7.Description:
(en)This application claims benefit of U.S. Provisional Application No. 60/612,873, filed Sep. 27, 2004, the contents of which are incorporated herein by reference. This application also claims benefit of priority under 35 U.S.C. § 119 to French Patent Application No. 04/51990, filed Sep. 8, 2004, the contents of which are also incorporated by reference.


Disclosed herein are novel cosmetic compositions, for example, hair compositions, comprising at least one cationic surfactant, at least one aminated silicone, at least one fatty alcohol, and at least one diol. Also disclosed is the use of these compositions in cosmetics, for example, in conditioners.
Conventional conditioners comprising a cationic surfactant and fatty alcohols may make it possible to obtain good cosmetic properties for the hair. However, the user may sometimes have the feeling that the hair is heavy and lank, and that it easily returns to a greasy condition, particularly if the hair is fine. Furthermore, for some hair types, the cosmetic properties of the conventional conditioner may be inadequate. In addition, the distribution of the product is sometimes difficult.
The present inventors have discovered that compositions comprising at least one cationic surfactant, at least one quaternized or non-quaternized aminated silicone, at least one fatty alcohol, and at least one diol comprising 6 carbon atoms, in certain ratios between the various constituents, may overcome the abovementioned disadvantages.
These compositions may also make it possible to render the fiber more supple, i.e., render the fiber less rough and more malleable.
The inventors have also found that, during application to fibers such as hair, the compositions may be easily distributed and easily spread from the roots to the ends, and/or may be easier to rinse out.
Finally, these compositions may confer good cosmetic properties on keratin fibers, such as the hair, for example, the hair may have improved disentangling and/or smoothness, the hair may be light and return more slowly to a greasy condition, and/or the hair may be very easily and/or lastingly shaped.
One embodiment of the present disclosure is thus a non-coloring cosmetic composition, for example, a hair composition, comprising, in a cosmetically acceptable medium, at least one cationic surfactant chosen from quaternary ammonium salts, at least one quaternized or non-quaternized aminated silicone, at least one fatty alcohol, and at least one diol comprising 6 carbon atoms, wherein the ratio of the weight concentrations of fatty alcohol/cationic surfactant is greater than or equal to 1, the ratio of the weight concentrations of cationic surfactant/silicone is greater than or equal to 0.85 and the ratio of the weight concentrations of fatty alcohol/silicone ranges from 2 to 15.
Another embodiment of the disclosure is a cosmetic haircare process comprising applying the compositions of the disclosure to the hair.
A further embodiment of the instant disclosure is a process for the cosmetic treatment of the hair and/or scalp comprising applying the compositions applying the compositions of the present disclosure to the hair and/or scalp.
Still a further embodiment of the present disclosure is a process for conditioning keratinous substances, such as the hair, comprising applying the compositions disclosed herein to the keratinous substances.
Other characteristics, aspects, subject-matters and advantages of the present disclosure will become even more clearly apparent on reading the description and examples which follow.
As used herein, the term “at least one” will be understood as meaning “one or more.”
As used herein, the term “cosmetically acceptable medium” is understood to mean a medium compatible with keratinous substances, such as the skin, hair, nails, eyelashes, eyebrows, lips, and/or any other region of the body and/or face.
As used herein, the term “non-coloring composition” is understood to mean a composition comprising essentially no oxidation dye, for example, less than 0.5% by weight, or less than 0.1% by weight with respect to the total weight of the composition, or comprising no oxidation dye.
The cosmetically acceptable medium may comprise at least one medium chosen from water, from cosmetically acceptable solvents, for example, hydrophilic solvents, and from water-solvent mixtures. These solvents may be alcohols, for example, linear or branched C 1 -C 6 monoalcohols, such as ethanol, tert-butanol, n-butanol, isopropanol, and n-propanol.
The cosmetically acceptable medium may be present in the composition in an amount ranging from 30% to 99% by weight, with respect to the total weight of composition, for example, from 60% to 90% by weight.

Compositions A and B were applied to the hair, followed by rinsing. Composition A was distributed more easily over the hairs from the root to the tip. Furthermore, composition A was easier to rinse out than composition B. The hair treated with composition A was also more supple under water.
It was observed that the hair treated with composition A was easier to disentangle and smoother than the hair treated with composition B.
EXAMPLE 2
A conditioning composition A according to the disclosure and a comparative composition B were prepared by combining the following components:
Composition A Composition B Cetearyl alcohol 5 g 5 g Behenyltrimethylammonium 3.2 g AM 3.2 g AM chloride Dipropylene glycol 1.27 g AM — Isopropanol — 1.27 g AM Myristyl/cetyl/stearyl 1 g 1 g myristate/palmitate/ stearate mixture Polydimethylsiloxane 1.05 g AM 1.05 g AM comprising an aminoethyliminopropyl group as a 35% aqueous emulsion (DC939 from Dow Corning) Fragrance, Preservatives q.s. q.s. pH agent q.s. pH 4 ± 0.5 pH 4 ± 0.5 Water q.s. for 100 g q.s. for 100 g

Compositions A and B were applied to the hair, followed by rinsing. Composition A was distributed more easily over the hairs from the root to the tip. Furthermore, composition A was easier to rinse out than composition B. The hair treated with composition A was also more supple under water.

EXAMPLE 3
A conditioning composition A according to the disclosure and a comparative composition B were prepared by combining the following components:
Composition A Composition B Cetearyl alcohol 7 g 7 g Behenyltrimethylammonium 5 g AM 5 g AM chloride Dipropylene glycol 2 g AM — Isopropanol — 2 g AM Myristyl/cetyl/stearyl 1.5 g 1.5 g myristate/palmitate/ stearate mixture Polydimethylsiloxane 1.75 g AM 1.75 g AM comprising an aminoethyliminopropyl group as a 35% aqueous emulsion (DC939 from Dow Corning) Glycerol 3 g 3 g Fragrance, Preservatives q.s. q.s. pH agent q.s. pH 4.5 ± 0.5 pH 4.5 ± 0.5 Water q.s. for 100 g q.s. for 100 g

Compositions A and B were applied to the hair, followed by rinsing. Composition A was easier to rinse out than composition B.
It was observed that the hair treated with composition A was easier to disentangle and smoother than the hair treated with composition B.
EXAMPLE 4
A conditioning composition A according to the disclosure and a comparative composition B were prepared by combining the following components:
Composition A Composition B Cetearyl alcohol 7 g 7 g Behenyltrimethylammonium 5 g AM 5 g AM chloride 1,6-Hexanediol 1.67 g AM — Isopropanol — 1.67 g AM Myristyl/cetyl/stearyl 1.5 g 1.5 g myristate/palmitate/ stearate mixture Polydimethylsiloxane 1.75 g AM 1.75 g AM comprising an aminoethyliminobutyl group as a 58% aqueous emulsion (DC2-8299 from Dow Corning) Glycerol 3 g 3 g Fragrance, Preservatives q.s. q.s. pH agent q.s. pH 4.5 ± 0.5 pH 4.5 ± 0.5 Water q.s. for 100 g q.s. for 100 g
