Patent Application
20160279049
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.
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.
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.
The following detailed description of the invention is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background of the invention or the following detailed description of the invention.
It has now been found that the above-discussed problems can be solved by means of a specific mixture of at least one surfactant and specific care substances.

The humectants can be used in the cleaning agents according to the invention preferably in amounts of 0.01 to 10 wt. %, more preferably in amounts of 0.05 to 5 wt. %, and particularly in amounts of 0.1 to 3 wt. % —with respect to the total weight of the cleaning agents according to the invention.
Further active substances, aids, and additives that can be used in the cleaning agents according to the invention are, for example:
The cosmetic compositions according to the invention preferably have pH values in the range of 2.5 to 6.5, preferably 3.5 to 6, and particularly 4 to 5.5.
As mentioned at the beginning, the cleaning agents according to the invention have excellent properties in use on hair. In addition to the gentle and thorough cleaning, they give hair treated therewith improved properties. Treated dry hair (particularly hair previously damaged in the structure thereof and fragile hair) has improved hair texture and greater smoothness, shine, and softness in addition to significantly less hair breakage. Treated wet hair (particularly hair previously damaged in the structure thereof and fragile hair) has fewer or no knots in addition to significantly less hair breakage. A further advantage of the cleaning agents according to the invention is that they support the resistance of the hair surface to physical and/or chemical hair damage.
Second, the present invention relates to the use of a cosmetic cleaning agent according to the invention to eliminate, reduce, and/or avoid hair breakage.
Third, the present invention relates to a method for cleaning hair and/or for eliminating, reducing, and/or avoiding hair breakage, wherein a cosmetic agent, including
a) at least one anionic and/or amphoteric (zwitterionic) surfactant,
b) at least one cationic polysaccharide,
c) at least one silicone,
d) at least one wax, and
e) at least one virgin oil and/or at least one cationic protein hydrolysate,
is applied to the preferably wet hair and is rinsed out with water after an exposure time of 5 seconds to 5 minutes.
Statements made with regard to the use according to the invention apply, mutatis mutandis, to preferred embodiments of the use according to the invention and to the method according to the invention.
The examples below should illustrate the subject matter of the invention without restricting the subject matter of the invention to said examples.
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:
The results in the table clearly show that the cleaning agents according to the invention fight hair breakage significantly better than comparable shampoos from the prior art.
