(en)CLAIM OF PRIORITY
This patent application claims the benefit of priority of U.S. Provisional Patent Application Ser. No. 61/411,170, entitled SHINY, TRANSFER RESISTANT LIPSTICK AND METHOD OF MAKING, which was filed on Nov. 8, 2010, and which is hereby incorporated by reference herein in its entirety.
FIELD
Inventive subject matter disclosed herein relates to lipstick and other anhydrous cosmetic embodiments and method embodiments for making lipstick and other anhydrous cosmetics having shiny, transfer resistant properties.
BACKGROUND
Lip coloring has had a long and interesting history. Women started coloring their lips at least about 5000 years ago when Mesopotamian women decorated their lips with crushed jewels. About 1500 BC to 3000 BC, women in the Indus Valley colored their lips with a red dye. According to Meg Cohen Ragas and Karen Kozlowski in their book, “Read My Lips: A Cultural History of Lipstick,” Egyptian women colored their lips with henna and with a preparation that included a purplish-red dye obtained from seaweed, iodine, and bromine marmite. It is believed that Cleopatra colored her lips with a formulation that included a dye extracted from crushed carmine beetles and ants.
During the period of Queen Elizabeth I, women colored their lips with a formulation that included beeswax and red dye. Queen Elizabeth herself, colored her lips black according to some sources and red, according to others. According to Ragas and Kozlowski, Thomas Hall, an English pastor and author of the “Loathsomeness of Long Haire” (1653), led a movement declaring that face painting was “the devil's work” and that women who put brush to mouth were trying to “ensnare others and to kindle a fire and flame of lust in the hearts of those who cast their eyes upon them.” In 1770, the British Parliament passed a law condemning lipstick, stating that “women found guilty of seducing men into matrimony by a cosmetic means could be tried for witchcraft.”
Modern lip coloring was formulated by perfumers in Paris in 1884. The lip coloring was wrapped in silk paper and made with deer tallow, castor oil and beeswax.

Ingredients of the shiny, long lasting transfer resistance include the following:
Gel
Gel embodiments include a blend of from 1 to 50 weight percent of at least one block copolymer, wherein the block copolymer has at least one polystyrene block and at least one unsaturated rubber block; and from 99 to 50 weight percent of natural oil. The composition results in a clear natural oil gel.
The block copolymer portion represents from 1 to 50% by weight of the composition. For some embodiments, the block copolymer is a single block copolymer or a mixture of different block copolymers. The block copolymers have unsaturated rubber blocks, for examples, SBS, SB, SIS, SI, (SB)n, and (SI)n. The block copolymers have a polystyrene content from 5% to 80%, for some embodiments from 10% to 50%, and for some embodiments, from 15% to 40% by weight of the block copolymer. Examples of these copolymers include Kraton® D Polymers and Vector® polymers.
The natural oils of the gel described herein may be plant or animal oils, and tend to be liquid at the room temperature. They are extracted from a wide range of plants and animals. An example of animal oils is fish oil. The most preferred natural oils of the invention are plant or vegetable oils. For example a preferred vegetable oil is jojoba oil, which is a monoester of eicosanoic and docosanoic acids and eicosanol and docosanol alcohols. Most other vegetable oils are triglycerides of glycerin and fatty acids which are largely unsaturated fatty acids such as oleic acid and linoleic acid. The vegetable oils of the present invention include non-genetically modified oils, genetically modified oils, organic grown oils, non-organic grown oils, and mixtures thereof.
In general, vegetable oils are readily available and prepared by extraction from plant seeds. Examples of the vegetable oils or plant oils include, but are not limited to, almond, avocado, castor, coconut, corn, cottonseed, olive, peanut, rice bran, safflower, sesame, soybean, sunflower, walnut, canola, refined palm, meadaowfoam, tea tree oil, etc.
The clear natural oil gels used in inventive lipstick embodiments described herein may additionally contain auxiliary ingredients including a) skirt compatible hydrophobic emollients including, but not limited to, sensory enhancers, synthetic esters, and hydrocarbon oils, the preferred ones being those derived from natural oils; b) skin benefit agents; and c) colorants, fumed silica, cornstarch, antioxidants, etc, Additional information regarding the gel is found in U.S. Pat. No 7,674,848, which is herein incorporated by reference.
Coconut Alkanes:
The coconut alkanes include a volatile oily composition having from 50 to 100% by weight of a mixture of linear paraffins that include 70 to 99% by weight of at least one linear paraffin selected from C %, C 10 , C 12 paraffins and mixtures thereof, (ii) 1 to 30% by weight of at least one C 14 to C 24 linear paraffin, and (b) from 0 to 50% by weight of at least one non-volatile oil.
As used herein, the word, “between” refers to including the cited limits.
The coconut alkanes have a volatility within the same range as cyclomethicones, i.e. a vapour pressure in the region of 0.001 to 300 mm Hg at ambient temperature (20° C.) and atmospheric pressure. The coconut alkanes form a film having a soft, non-greasy touch and a reduced gloss similar to those of cyclomethicones. This oily composition further has a flash point (measured as per the ASTM D93 standard) below 100° C., and/or a kinematic viscosity below 5 cSt, or between 1 and 3 cSt, at 40° C. This association of raw materials may thus partly or completely substitute the volatile silicones conventionally used in cosmetic compositions and more particularly cyclopentasiloxane and mixtures containing same (such as DC345® sold by DOW CORNING). The paraffins (or fatty alkanes) contained in the oily composition according to the invention may be advantageously obtained according to a method comprising the following successive steps:
1—dehydration of at least one Ce-C 24 fatty alcohol to obtain an alkene, and
2—hydrogenation of said alkene to an alkane. The first step of this method may particularly be implemented as described in the document US 2008/0287722, i.e. at a temperature of 190 to 260° C., for some embodiments, temperatures of 220 to 250° C., in the presence of a dehydration catalyst consisting of trifluoromethane sulphonic acid, which may represent 0.5 to 3% of the weight of the alcohol, for example. The alcohol dehydrated in this step may be obtained from plant sources and particularly be obtained by saponification of natural oils or fats. However, it is preferable for it to be obtained according to a method comprising a transesterification step of fatty acid triglycerides, for some embodiments, of plant origin, followed by a hydrogenation step of the fatty acid esters (for example methyl esters) obtained. The use of fatty alcohols of plant origin leads to alkenes containing an even number of carbon atoms, generally mixture form. This mixture may also comprise a minor amount of branched alkenes.
The second step of this method may be implemented in a conventional manner for those skilled in the art, according to techniques used in the food processing industry for hydrogenating oils, and particularly placing the alkene(s) in contact with a catalyst comprising a transition metal. The alkanes obtained preferably contain, as above, an even number of carbon atoms. They are linear, although they may also include a minor amount of branched alkanes.
Obviously, this method may further comprise other steps (preliminary, intermediate and/or subsequent steps) than those mentioned above. Alternatively, commercially available paraffins, such as those available from SASOL under the brand name Parafol® (particularly Parafol® 14-97 for tetradecane) may be used in the oily composition according to the invention. The oily composition. according to the invention comprises 70 to 99% by weight, for example 70 to 90% or 90 to 99% by weight, Cg, C 10 and/or C 12 paraffin(s) and 1 to 30% by weight, for example 10 to 30% or 1 to 10% by weight, C 14 to C 24 paraffin(s). These two types of paraffins may be obtained separately and mixed, or obtained jointly from a mixture of fatty alcohols, particularly of plant origin, according to the method described above. Among the C %, C 10 and/or C 12 paraffin(s), the C 12 paraffin is preferred. Moreover, as explained above, the C 14 to C 24 paraffin(s) are preferably chosen among those having an even number of carbon atoms, still preferably the C 14 paraffin. Furthermore, preferably, the oily composition according to the invention comprises, or consists only of, dodecane and tetradecane.
In addition to the abovementioned paraffins, and according to the desired. volatility, the oily composition according to the invention may contain at least one non-volatile oil. According to the present invention, the term “oil” refers to a liquid compound at ambient temperature (25° C.), which, when introduced at a rate of at least 1% by weight in water at 25° C., is not at all soluble in water, or soluble at a rate of less than 10% by weight, with reference to the weight of oil introduced into the water, In this description, the term “non-volatile oil” refers to an oil remaining on the skin at ambient temperature and atmospheric pressure for a plurality of hours, in the absence of friction, and/or having a vapour pressure less than 0.001 mm Hg under these conditions.
Examples of non-volatile oils include: mineral or synthetic branched hydrocarbons, synthetic (poly)esters and (poly)ethers and particularly (polylesters of C 2 -C 24 (such as C 6 -C 20 ) acids and C 2 -C 24 (such as C 6 - C 20 ) alcohols or polyols, which are advantageously branched, C o -C 20 fatty acid triglycerides, vegetable oils, dialkyl carbonates such as dicaprylyl carbonate, branched and/or unsaturated fatty acids (such as linoleic and linolenic acids), branched and/or unsaturated fatty alcohols (such as octyldodecanol or hexyldecanol), silicone oils, fluorosilicone oils, fluorinated oils, and mixtures thereof. The term “hydrocarbon” refers to an oil containing only hydrogen and carbon atoms. Examples of non-volatile hydrocarbon oils are polybutene, hydrogenated polyisobutene, polydecene, hydrogenated polydecene, squalane, non-volatile paraffin oils and mixtures thereof. The (poly)esters of C 2 -C 24 acids and C 0 -C 20 alcohols and polyols, which represent the preferred category of non-volatile oils according to the invention, particularly include mono- and diesters such as ethyl acetate, isopropyl acetate, oleyl acetate, isononyl isononanoate, isononanoate, hexyl neopentanoate, ethylhexyl neopentanoate, isodecyl neopentanoate, isostearyl neopentanoate, heptyl undecylenate, neopentylglycol diheptanoate, neopentylglycol diethylhexanoate, pentaerythrityl tetraethylhexanoate, propanediol dicaprylate, neopentylglycol dicaprylate/dicaprate isopropyl myristate, isopropyl palmitate, hexyl laurate, the mixture of coco caprate and caprylate, C 12 to C 15 alcohol benzoates, and mixtures thereof.
Examples of vegetable oils are in particular wheat germ, sunflower, grape seed, sesame, corn, apricot, castor, shea, avocado, olive, soya, sweet almond, palm, rapeseed, cotton, hazelnut, macadamia, jojoba, alfalfa, poppy seed, pumpkin seed, sesame, marrow, rapeseed, blackcurrant, evening primrose, millet, barley, quinoa, rye, safflower, candlenut, passiflora, musk rose or camellia oils.
The term “silicone oil” refers to an oil comprising at least one silicon atom, and particularly at least one Si-O group. Non-volatile silicon oils particularly include polydimethylsiloxanes containing at least 8 silicon atoms, polyalkylmethylsiloxanes in which the alkyl chain contains 8 to 20 carbon atoms and oils identified using the INCI name phenyl trimethicone.
The oily composition according to the invention contains 50 to 100% by weight of paraffin mixture and 0 to 50% by weight of non-volatile oil(s), for example 70 to 95% by weight, for some embodiments, 85 to 95% by weight, of paraffin mixture and 5 to 30% by weight, for some embodiments, 5 to 15% by weight, of non-volatile oil(s). Oily compositions according to this invention are also marketed by One coconut alkane formulation is sold by BIOSYNTHIS under the trade name Vegelight®. 1214.

Fragrances
Embodiments disclosed herein are either fragrance free or include a fragrance compatible with lipstick, In one embodiment, the fragrance is Fleuri.
In one embodiment, the lipstick of high transfer resistance is made with a three-roller mill, a stirrer and a propeller. One step of the method includes preparing a colorant phase. The colorant phase includes combining colorant ingredients such as D&C Red NO. 7 Calcium Lake, iron oxides, titanium dioxide, and other colorants as desired. Coconut alkanes, such as Vegelight 1214C, are added to the colorant ingredients in a concentration effective to make a paste. The paste is passed through a 3-roller at least 3-4 times. The pigment grind is checked under a Hegman gauge to ensure good pigment dispersion.
In another step, a coconut gel, such as Nature Vgel, is added to a container, such as a reactor. The coconut gel is heated to 85 to 90° C. The coconut gel is mixed to obtain a uniform mixture. Polyethylene is added to the heated coconut gel at a temperature of 85 to 90° C. to form a PE-gel mixture. The PE-gel mixture is then well mixed to ensure that waxes are completely melted or homogeneous,
Coconut alkanes, for some embodiments, Vegelight 1214C are added to the coconut gel and polyethylene mixture at a temperature of 85° C. to 90° C., forming a PE-gel-alkane mixture. The PE-gel-alkane mixture then mixed,
Acacia Decurrens/Jojoba/Sunflower Seed wax/Polyglyeryl 3-ester is added to the PE-gel-alkane mixture. Caprylyl glycol is also added to the coconut alkanes, gel mixture.
The colorant paste, including the coconut alkanes, is quickly added to the heated mixture of coconut gel and polyethylene to form a new mixture. The new mixture is mixed and held at a temperature within a range of 85 to 90° C.
The temperature of 85° C. to 90° C. is maintained. Mica and lauroyl lysine, titanium dioxide and mica and mica are added one at a time to the new mixture.
For some embodiments, a fragrance is added to the mixture and mixed. The mixture is then poured into stick molds at 85° C., to make lipstick.
Compositions that include coconut alkanes having a volatile oily composition having from 50 to 100% by weight of a mixture of linear paraffins that include 70 to 99% by weight of at least one linear paraffin selected from C %, C 10 , C 12 paraffins and mixtures thereof; a coconut gel comprising vegetable oil, Cocos Nucifera Oil, a styrenelbutadiene copolymer and polyethylene; polyethylene, caprylyl glycol, and a mixture of Acacia Decurrens/Jojoba/Sunflower Seed wax/Polyglyceryl 3-ester in concentrations effective for ensuring coconut alkanes are melted and homogeneous; and one or more anhydrous actives are usable in a variety of anhydrous cosmetics, in addition to lipstick. The anhydrous cosmetics include skin care compositions, scalp care compositions, and compositions for hair, eyelashes and nails. The anhydrous cosmetics disclosed herein have an improved transfer resistance.
Skin care and other cosmetic anhydrous actives include but are not limited to petroleum-based emollients, vegetable oils, hydrogenated vegetable oils, and their derivatives; branched hydrocarbons; fatty alcohol ethers; free sterols, sterol esters and their derivatives; sphingolipids; phospholipids; and mixtures thereof. Suitable petroleum-based emollient include petrolatums, i.e., hydrocarbons or mixtures of hydrocarbons; particularly preferred are hydrocarbons having chain lengths of from C10 to C100. Petroleum-based emollients within this chain length range include mineral oil and petrolatum. Mineral oil usually refers to less viscous mixtures of hydrocarbons having from 10 to 30 carbon atoms, though the hydrocarbon molecular weight distribution may vary. Since the lower molecular weight hydrocarbons can cause irritation in some individuals, mineral oils having a small percentage of lower molecular weight hydrocarbons are preferred. Petrolatum usually refers to more viscous mixtures of hydrocarbons of higher molecular weight hydrocarbons.
The transfer resistance of a lipstick made with the formulation disclosed in the table herein was evaluated. In particular, panelists were given a blinded lipstick sample and applied an even coat of the lipstick and let it dry for fifteen minutes. All panelists were women above the age of eighteen years. Each panelist was given a white tile to kiss using moderate pressure. Three expert evaluators scored the amount of transfer according to the Lipstick Transfer Scale, as illustrated in FIG. 1.

Ingredients of the shiny, long lasting transfer resistance include the following:
Gel
Gel embodiments include a blend of from 1 to 50 weight percent of at least one block copolymer, wherein the block copolymer has at least one polystyrene block and at least one unsaturated rubber block; and from 99 to 50 weight percent of natural oil. The composition results in a clear natural oil gel.
The block copolymer portion represents from 1 to 50% by weight of the composition. For some embodiments, the block copolymer is a single block copolymer or a mixture of different block copolymers. The block copolymers have unsaturated rubber blocks, for examples, SBS, SB, SIS, SI, (SB)n, and (SI)n. The block copolymers have a polystyrene content from 5% to 80%, for some embodiments from 10% to 50%, and for some embodiments, from 15% to 40% by weight of the block copolymer. Examples of these copolymers include Kraton® D Polymers and Vector® polymers.
The natural oils of the gel described herein may be plant or animal oils, and tend to be liquid at the room temperature. They are extracted from a wide range of plants and animals. An example of animal oils is fish oil. The most preferred natural oils of the invention are plant or vegetable oils. For example a preferred vegetable oil is jojoba oil, which is a monoester of eicosanoic and docosanoic acids and eicosanol and docosanol alcohols. Most other vegetable oils are triglycerides of glycerin and fatty acids which are largely unsaturated fatty acids such as oleic acid and linoleic acid. The vegetable oils of the present invention include non-genetically modified oils, genetically modified oils, organic grown oils, non-organic grown oils, and mixtures thereof.
In general, vegetable oils are readily available and prepared by extraction from plant seeds. Examples of the vegetable oils or plant oils include, but are not limited to, almond, avocado, castor, coconut, corn, cottonseed, olive, peanut, rice bran, safflower, sesame, soybean, sunflower, walnut, canola, refined palm, meadaowfoam, tea tree oil, etc.
The clear natural oil gels used in inventive lipstick embodiments described herein may additionally contain auxiliary ingredients including a) skirt compatible hydrophobic emollients including, but not limited to, sensory enhancers, synthetic esters, and hydrocarbon oils, the preferred ones being those derived from natural oils; b) skin benefit agents; and c) colorants, fumed silica, cornstarch, antioxidants, etc, Additional information regarding the gel is found in U.S. Pat. No 7,674,848, which is herein incorporated by reference.
Coconut Alkanes:
The coconut alkanes include a volatile oily composition having from 50 to 100% by weight of a mixture of linear paraffins that include 70 to 99% by weight of at least one linear paraffin selected from C %, C 10 , C 12 paraffins and mixtures thereof, (ii) 1 to 30% by weight of at least one C 14 to C 24 linear paraffin, and (b) from 0 to 50% by weight of at least one non-volatile oil.
As used herein, the word, “between” refers to including the cited limits.
The coconut alkanes have a volatility within the same range as cyclomethicones, i.e. a vapour pressure in the region of 0.001 to 300 mm Hg at ambient temperature (20° C.) and atmospheric pressure. The coconut alkanes form a film having a soft, non-greasy touch and a reduced gloss similar to those of cyclomethicones. This oily composition further has a flash point (measured as per the ASTM D93 standard) below 100° C., and/or a kinematic viscosity below 5 cSt, or between 1 and 3 cSt, at 40° C. This association of raw materials may thus partly or completely substitute the volatile silicones conventionally used in cosmetic compositions and more particularly cyclopentasiloxane and mixtures containing same (such as DC345® sold by DOW CORNING). The paraffins (or fatty alkanes) contained in the oily composition according to the invention may be advantageously obtained according to a method comprising the following successive steps:
1—dehydration of at least one Ce-C 24 fatty alcohol to obtain an alkene, and
2—hydrogenation of said alkene to an alkane. The first step of this method may particularly be implemented as described in the document US 2008/0287722, i.e. at a temperature of 190 to 260° C., for some embodiments, temperatures of 220 to 250° C., in the presence of a dehydration catalyst consisting of trifluoromethane sulphonic acid, which may represent 0.5 to 3% of the weight of the alcohol, for example. The alcohol dehydrated in this step may be obtained from plant sources and particularly be obtained by saponification of natural oils or fats. However, it is preferable for it to be obtained according to a method comprising a transesterification step of fatty acid triglycerides, for some embodiments, of plant origin, followed by a hydrogenation step of the fatty acid esters (for example methyl esters) obtained. The use of fatty alcohols of plant origin leads to alkenes containing an even number of carbon atoms, generally mixture form. This mixture may also comprise a minor amount of branched alkenes.
The second step of this method may be implemented in a conventional manner for those skilled in the art, according to techniques used in the food processing industry for hydrogenating oils, and particularly placing the alkene(s) in contact with a catalyst comprising a transition metal. The alkanes obtained preferably contain, as above, an even number of carbon atoms. They are linear, although they may also include a minor amount of branched alkanes.
Obviously, this method may further comprise other steps (preliminary, intermediate and/or subsequent steps) than those mentioned above. Alternatively, commercially available paraffins, such as those available from SASOL under the brand name Parafol® (particularly Parafol® 14-97 for tetradecane) may be used in the oily composition according to the invention. The oily composition. according to the invention comprises 70 to 99% by weight, for example 70 to 90% or 90 to 99% by weight, Cg, C 10 and/or C 12 paraffin(s) and 1 to 30% by weight, for example 10 to 30% or 1 to 10% by weight, C 14 to C 24 paraffin(s). These two types of paraffins may be obtained separately and mixed, or obtained jointly from a mixture of fatty alcohols, particularly of plant origin, according to the method described above. Among the C %, C 10 and/or C 12 paraffin(s), the C 12 paraffin is preferred. Moreover, as explained above, the C 14 to C 24 paraffin(s) are preferably chosen among those having an even number of carbon atoms, still preferably the C 14 paraffin. Furthermore, preferably, the oily composition according to the invention comprises, or consists only of, dodecane and tetradecane.
In addition to the abovementioned paraffins, and according to the desired. volatility, the oily composition according to the invention may contain at least one non-volatile oil. According to the present invention, the term “oil” refers to a liquid compound at ambient temperature (25° C.), which, when introduced at a rate of at least 1% by weight in water at 25° C., is not at all soluble in water, or soluble at a rate of less than 10% by weight, with reference to the weight of oil introduced into the water, In this description, the term “non-volatile oil” refers to an oil remaining on the skin at ambient temperature and atmospheric pressure for a plurality of hours, in the absence of friction, and/or having a vapour pressure less than 0.001 mm Hg under these conditions.
Examples of non-volatile oils include: mineral or synthetic branched hydrocarbons, synthetic (poly)esters and (poly)ethers and particularly (polylesters of C 2 -C 24 (such as C 6 -C 20 ) acids and C 2 -C 24 (such as C 6 - C 20 ) alcohols or polyols, which are advantageously branched, C o -C 20 fatty acid triglycerides, vegetable oils, dialkyl carbonates such as dicaprylyl carbonate, branched and/or unsaturated fatty acids (such as linoleic and linolenic acids), branched and/or unsaturated fatty alcohols (such as octyldodecanol or hexyldecanol), silicone oils, fluorosilicone oils, fluorinated oils, and mixtures thereof. The term “hydrocarbon” refers to an oil containing only hydrogen and carbon atoms. Examples of non-volatile hydrocarbon oils are polybutene, hydrogenated polyisobutene, polydecene, hydrogenated polydecene, squalane, non-volatile paraffin oils and mixtures thereof. The (poly)esters of C 2 -C 24 acids and C 0 -C 20 alcohols and polyols, which represent the preferred category of non-volatile oils according to the invention, particularly include mono- and diesters such as ethyl acetate, isopropyl acetate, oleyl acetate, isononyl isononanoate, isononanoate, hexyl neopentanoate, ethylhexyl neopentanoate, isodecyl neopentanoate, isostearyl neopentanoate, heptyl undecylenate, neopentylglycol diheptanoate, neopentylglycol diethylhexanoate, pentaerythrityl tetraethylhexanoate, propanediol dicaprylate, neopentylglycol dicaprylate/dicaprate isopropyl myristate, isopropyl palmitate, hexyl laurate, the mixture of coco caprate and caprylate, C 12 to C 15 alcohol benzoates, and mixtures thereof.
Examples of vegetable oils are in particular wheat germ, sunflower, grape seed, sesame, corn, apricot, castor, shea, avocado, olive, soya, sweet almond, palm, rapeseed, cotton, hazelnut, macadamia, jojoba, alfalfa, poppy seed, pumpkin seed, sesame, marrow, rapeseed, blackcurrant, evening primrose, millet, barley, quinoa, rye, safflower, candlenut, passiflora, musk rose or camellia oils.
The term “silicone oil” refers to an oil comprising at least one silicon atom, and particularly at least one Si-O group. Non-volatile silicon oils particularly include polydimethylsiloxanes containing at least 8 silicon atoms, polyalkylmethylsiloxanes in which the alkyl chain contains 8 to 20 carbon atoms and oils identified using the INCI name phenyl trimethicone.
The oily composition according to the invention contains 50 to 100% by weight of paraffin mixture and 0 to 50% by weight of non-volatile oil(s), for example 70 to 95% by weight, for some embodiments, 85 to 95% by weight, of paraffin mixture and 5 to 30% by weight, for some embodiments, 5 to 15% by weight, of non-volatile oil(s). Oily compositions according to this invention are also marketed by One coconut alkane formulation is sold by BIOSYNTHIS under the trade name Vegelight®. 1214.

Fragrances
Embodiments disclosed herein are either fragrance free or include a fragrance compatible with lipstick, In one embodiment, the fragrance is Fleuri.
In one embodiment, the lipstick of high transfer resistance is made with a three-roller mill, a stirrer and a propeller. One step of the method includes preparing a colorant phase. The colorant phase includes combining colorant ingredients such as D&C Red NO. 7 Calcium Lake, iron oxides, titanium dioxide, and other colorants as desired. Coconut alkanes, such as Vegelight 1214C, are added to the colorant ingredients in a concentration effective to make a paste. The paste is passed through a 3-roller at least 3-4 times. The pigment grind is checked under a Hegman gauge to ensure good pigment dispersion.
In another step, a coconut gel, such as Nature Vgel, is added to a container, such as a reactor. The coconut gel is heated to 85 to 90° C. The coconut gel is mixed to obtain a uniform mixture. Polyethylene is added to the heated coconut gel at a temperature of 85 to 90° C. to form a PE-gel mixture. The PE-gel mixture is then well mixed to ensure that waxes are completely melted or homogeneous,
Coconut alkanes, for some embodiments, Vegelight 1214C are added to the coconut gel and polyethylene mixture at a temperature of 85° C. to 90° C., forming a PE-gel-alkane mixture. The PE-gel-alkane mixture then mixed,
Acacia Decurrens/Jojoba/Sunflower Seed wax/Polyglyeryl 3-ester is added to the PE-gel-alkane mixture. Caprylyl glycol is also added to the coconut alkanes, gel mixture.
The colorant paste, including the coconut alkanes, is quickly added to the heated mixture of coconut gel and polyethylene to form a new mixture. The new mixture is mixed and held at a temperature within a range of 85 to 90° C.
The temperature of 85° C. to 90° C. is maintained. Mica and lauroyl lysine, titanium dioxide and mica and mica are added one at a time to the new mixture.
For some embodiments, a fragrance is added to the mixture and mixed. The mixture is then poured into stick molds at 85° C., to make lipstick.
Compositions that include coconut alkanes having a volatile oily composition having from 50 to 100% by weight of a mixture of linear paraffins that include 70 to 99% by weight of at least one linear paraffin selected from C %, C 10 , C 12 paraffins and mixtures thereof; a coconut gel comprising vegetable oil, Cocos Nucifera Oil, a styrenelbutadiene copolymer and polyethylene; polyethylene, caprylyl glycol, and a mixture of Acacia Decurrens/Jojoba/Sunflower Seed wax/Polyglyceryl 3-ester in concentrations effective for ensuring coconut alkanes are melted and homogeneous; and one or more anhydrous actives are usable in a variety of anhydrous cosmetics, in addition to lipstick. The anhydrous cosmetics include skin care compositions, scalp care compositions, and compositions for hair, eyelashes and nails. The anhydrous cosmetics disclosed herein have an improved transfer resistance.
Skin care and other cosmetic anhydrous actives include but are not limited to petroleum-based emollients, vegetable oils, hydrogenated vegetable oils, and their derivatives; branched hydrocarbons; fatty alcohol ethers; free sterols, sterol esters and their derivatives; sphingolipids; phospholipids; and mixtures thereof. Suitable petroleum-based emollient include petrolatums, i.e., hydrocarbons or mixtures of hydrocarbons; particularly preferred are hydrocarbons having chain lengths of from C10 to C100. Petroleum-based emollients within this chain length range include mineral oil and petrolatum. Mineral oil usually refers to less viscous mixtures of hydrocarbons having from 10 to 30 carbon atoms, though the hydrocarbon molecular weight distribution may vary. Since the lower molecular weight hydrocarbons can cause irritation in some individuals, mineral oils having a small percentage of lower molecular weight hydrocarbons are preferred. Petrolatum usually refers to more viscous mixtures of hydrocarbons of higher molecular weight hydrocarbons.
The transfer resistance of a lipstick made with the formulation disclosed in the table herein was evaluated. In particular, panelists were given a blinded lipstick sample and applied an even coat of the lipstick and let it dry for fifteen minutes. All panelists were women above the age of eighteen years.
