7.Description:
(en)FIELD OF THE INVENTION
The present invention generally relates to cosmetics, and more particularly relates to rinse-out cleaning agents that are used to eliminate, reduce, and/or prevent hair breakage and a method for cleaning hair and/or for eliminating, reducing, and/or preventing hair breakage.
BACKGROUND OF THE INVENTION
Cosmetic cleaning agents, such as hair shampoos, are usually based on traditional anionic, amphoteric, zwitterionic, non-ionic, and/or cationic surfactants. Because of their excellent cleaning and foaming ability, anionic surfactants are predominantly used, possibly in mixture with small amounts of co-surfactants. Such a commercially available shampoo cleans the hair and eliminates sebum residues and/or residues of styling agents and other soiling from the hair surface and the scalp. However, lipids and proteins are also removed from the hair and the scalp during the cleaning, whereby damage to the hair structure and/or drying out of the scalp can occur, especially if cleaning is performed frequently. Damage to the hair structure or the hair fibers, particularly split ends and/or hair breakage, can additionally be promoted by environmental influences (for example, intense solar irradiation), mechanical loads (for example, combing while blow-drying heat is applied), and chemical influences (for example, dyeing, shaping, or smoothing of the hair).
Numerous hair care agents, such as hair masks, conditioners, or hair care lotions, that can be used successfully to treat split ends and/or hair breakage are known from the prior art. However, for reasons of time and cost, hair cleaning agents that simultaneously have a care effect and a repair effect on the hair are desired by consumers for daily use.
The formulation of 2-in-1 or 3-in-1 preparations has also been known in the prior art for a long time. For example, in DE 102012201861, a conditioning hair cleaning agent that includes a cationic guar polymer, a silicone emulsion, and at least one wax in addition to an anionic surfactant is proposed. The cleaning agents having high foaming capability and give the hair improved combability and improved optical and tactile properties after the cleaning agents have been applied. However, it has been found that these agents and comparable 2-in-1 cleaning preparations known from the prior art must be optimized further, particularly with regard to the repair of damaged hair fibers and the strengthening of the hair structure.
It is therefore desirable to provide mild, care-providing hair cleaning agents that are safe for skin and hair, are highly effective against hair damage, and optimally strengthen the hair structure.
Furthermore, other desirable features and characteristics of the present invention will become apparent from the subsequent detailed description of the invention and the appended claims, taken in conjunction with this background of the invention.
BRIEF SUMMARY OF THE INVENTION
A cosmetic cleaning agent includes in a cosmetic vehicle, at least one anionic and/or amphoteric (zwitterionic) surfactant, at least one cationic polysaccharide, at least one silicone, at least one wax, and at least one virgin oil and/or at least one cationic protein hydrolysate.
A method for cleaning hair and/or for eliminating, reducing, and/or avoiding hair breakage includes applying to preferably wet hair a cosmetic agent that includes at least one anionic and/or amphoteric (zwitterionic) surfactant, at least one cationic polysaccharide, at least one silicone, at least one wax, and at least one virgin oil and/or at least one cationic protein hydrolysate. The agent is rinsed out with water after an exposure time of 5 seconds to 5 minutes.

2) Evaluation of Shampoos According to the Invention
Two compositions were produced. A composition according to the invention corresponded to example 1 (A) of the table provided above and a second composition not according to the invention corresponded to a commercially available care shampoo for hair that is fragile and susceptible to split ends (B), which included 0.7 wt. % of Polymer JR 400 and 0.2 wt. % of polydimethylsiloxane instead of the care complex according to the invention, consisting of Guar Hydroxypropyltrimonium Chloride, polydimethyl siloxane, manila oil, Hydrogenated Castor Oil, and Cocodimonium Hydroxypropyl Hydrolyzed Keratin. The two compositions were applied to identically pretreated (cleaned and then pre-damaged) hair strands from Kerling International (Backnang, Germany—European natural hair 7/0; lot #04/2010; N74; length: 12 cm; weight: 1+/−0.05 g) in a typical manner and then the reduction in hair breakage was determined.
The results can be found in the following table:
