Patent Application
20170151163
This application claims priority to German Patent Application No. 10 2015 223 845.8, filed Dec. 1, 2015, which is incorporated herein by reference in its entirety.
The disclosure relates to hair treatment agents, in particular shampoos and so-called conditioners, with an active substance combination for the gentle and effective care of hair.
The importance of care products with the longest-lasting possible effect is increasing not least due to the great stressing of hair, for example, by coloring or permanents, as well as by cleaning the hair with shampoos and by harmful environmental factors. Care products of this type influence the natural structure and properties of hair. Thus, after such care treatments, for example, the wet and dry combability of hair, the hold, and fullness of the hair can be optimized or the hair can be protected from an increase in split ends.
It has long been customary, therefore, to subject hair to a special aftertreatment. In this regard, the hair is treated with special active substances, for example, quaternary ammonium salts or special polymers, usually in the form of a rinse. Depending on the formulation, the combability, hold, and fullness of the hair can be improved by this treatment and the splitting rate reduced.
Multifunctional cosmetic products are also known in the prior art. These include in particular the so-called “2 in 1” shampoos, which not only clean the hair but also condition it. Such products are highly valued by the consumer, because due to their product performance they make at least one process step unnecessary, for example, the conditioning with a classic hair rinse.
Similarly, products for modifying the natural hair color play a prominent role in hair cosmetics. Permanent, semipermanent, or temporary coloring systems are differentiated, which are based on chemical and/or natural dyes. The hair colors produced artificially by permanent, semipermanent, or temporary coloring systems have the disadvantage, however, that they can change in an undesirable way, for example, during or after the cleaning of hair.
An “undesirable change” is understood to be the fading or bleeding and the loss of color brilliance of the hair shade achieved by the particular dyeing. Environmental effects and/or the effects of sunlight can intensify these changes further still.
The use of divalent metal salts in hair dyes to improve the durability and thereby the fastness of the color is known from EP 2438900 A1.
There continues to be a need to provide active substances or active substance combinations for hair treatment agents with good care properties, which, moreover, strengthen the adhesion of dyes to hair fibers and thus maintain the fastness of the artificially produced hair color, and in this respect to develop hair treatment agents further.
It was observed, however, that water hardness at times can have a negative effect on the care properties of hair treatment agents, so that the care performance of the same product is either too-low or too-high depending on the water quality.
A too-high care performance or “overcare” (occurrence of a so-called build-up effect) of the hair is understood primarily as a greasy hair feel, smaller hair volume, and/or a stringy, unkempt appearance of the hair, whereas damaged (brittle, prone to splitting, dull) hair is an indication of a too-low care performance.
Hair treatment agents and methods are provided herein. In an embodiment, a hair treatment agent includes:
In another embodiment, a method for treating hair includes applying a hair treatment agent to dry or damp hair, wherein the hair treatment agent includes:
The following detailed description is merely exemplary in nature and is not intended to limit the hair treatment agents and methods for treating hair. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.
The object of the present application therefore was to provide highly skin-compatible hair treatment agents with care properties, which have excellent foam properties and have a good rinsability with water and, moreover, reduce or prevent the washing out of color from dyed hair.
The hair treatment agents with care properties should have, independent of the water quality, an unvarying conditioning performance and not weigh down in particular fine hair and/or damaged hair and thereby strengthen the hair's structure and thus protect from splitting and breaking and improve combability and feel. Moreover, it should have a germ-reducing effect.
It has now been found that a combination of certain ingredients has an especially positive effect on dyed hair treated therewith and on the hair follicle.
A first subject as contemplated herein as contemplated herein is hair treatment agents, containing
Hair treatment agents in the context as contemplated herein as contemplated herein are, for example, hair shampoos, hair conditioners, conditioning shampoos, hair sprays, hair rinses, hair treatments, hair packs, hair tonics, permanent wave fixing solutions, hair coloring shampoos, hair dyes, hair setting lotions, hair setting products, hair styling preparations, blow-dry wave lotions, styling mousses, hair gels, hair waxes, or combinations thereof.

These silicones are designated as Trimethylsilylamodimethicone in accordance with the INCI Declaration.
Particularly preferred as well are agents as contemplated herein that contain an amino-functional silicone of the formula (Si-IIb)
in which R stands for —OH, —O—CH3, or a —CH3 group and m, n1 and n2 are numbers, whose sum (m+n1+n2) amounts to between 1 and about 2000, preferably between 50 and about 150, the sum (n1+n2) preferably assuming values from 0 to about 1999 and in particular from 49 to about 149 and m preferably assuming values from 1 to about 2000, in particular from 1 to 10.
These silicones are designated as Amodimethicone in accordance with the INCI Declaration.
Irrespective of which amino-functional silicones are used, agents as contemplated herein are preferred that contain an amino-functional silicone whose amine value is above about 0.25 mEq/g, preferably above about 0.3 mEq/g, and in particular above about 0.4 mEq/g. The amine value here stands for the milliequivalents of amine per gram of the amino-functional silicone. It can be determined by titration and may also be given in the unit mg of KOH/g.
Agents preferred as contemplated herein are characterized in that, based on their weight, they contain about 0.01 to about 20% by weight, preferably about 0.1 to about 10% by weight, particularly preferably about 0.5 to about 7.5% by weight, and in particular about 1 to about 5% by weight of amino-functional silicone(s).
The agents as contemplated herein contain with particular preference amino-functional silicone(s) with terminal hydroxy group(s). Some special amino-functional silicone(s) with terminal hydroxy group(s) have emerged as being especially suitable in the agents as contemplated herein. These are described hereafter.
Agents preferred as contemplated herein are characterized in that, based on their weight, they contain about 0.01 to about 20% by weight, preferably about 0.1 to about 10% by weight, particularly preferably about 0.5 to about 7.5% by weight, and in particular about 1 to about 5% by weight of at least one silicone of the following formula (Si-III)
in which
Further agents preferred as contemplated herein are characterized in that, based on their weight, they contain about 0.01 to about 20% by weight, preferably about 0.1 to about 10% by weight, particularly preferably about 0.5 to about 7.5% by weight, and in particular about 1 to about 5% by weight of at least one silicone of the following formula (Si-IV)
in which
The silicones of the formulas (Si-III) and (Si-IV) differ by the grouping on the Si atom that carries the nitrogen-containing group: In formula (Si-III), R2 denotes a hydroxy group or a C1-4 alkoxy group, whereas the group in formula (Si-IV) is a methyl group. The individual Si groupings, which are labeled with the subscripts m and n or p and q, need not be present as blocks, but rather the individual units can also be distributed randomly; i.e., in the formulas (Si-III) and (Si-IV) each R1-Si(CH3)2 group is not necessarily bound to a —[O—Si(CH3)2] grouping.
Pretreatment agents that contain at least one silicone of the formula (Si-V) have emerged as especially effective in the method as contemplated herein in regard to the desired effects:
in which
Agents as contemplated herein that contain, based on their weight, about 0.01 to about 20% by weight, preferably about 0.1 to about 10% by weight, particularly preferably about 0.5 to about 7.5% by weight, and in particular about 1 to about 5% by weight of at least one silicone of the formula (Si-V):
in which
In the aforementioned formula (Si-V), the individual siloxane units with the subscripts b, c, and n are randomly distributed; i.e., they need not necessarily be block copolymers.
Further particularly suitable silicones are 4-morpholinomethyl-substituted. Agents as contemplated herein are particularly preferred, which, based on their weight, contain about 0.01 to about 20% by weight, preferably about 0.1 to about 10% by weight, particularly preferably about 0.5 to about 7.5% by weight, and in particular about 1 to about 5% by weight of at least one 4-morpholinomethyl-substituted silicone of the formula (Si-VI).
in which
Structural formula (Si-VI) is intended to clarify that the siloxane groups n and o need not necessarily be bound directly to an end grouping B or D. Instead, in preferred formulas (Si-VI) a>0 or b>0 and in particularly preferred formulas (Si-VI) a>0 and b>0; i.e., the terminal grouping B or D is preferably bound to a dimethylsiloxy grouping. In formula (Si-VI) as well, the siloxane units a, b, c, n, and o are preferably distributed randomly.
The silicones represented by formula (Si-VI) and used as contemplated herein can be trimethylsilyl-terminated (D or B=—Si(CH3)3), but they may also be dimethylsilylhydroxy-terminated at both ends or dimethylsilylhydroxy- and dimethylsilylmethoxy-terminated at one end. In the context as contemplated herein, silicones used with particular preference are selected from silicones in which
In formula (Si-VI) as well, the A group can stand
Thus, formula (Si-VI) is more precisely one of the formulas (Si-VIa), (Si-VIb), or (Si-VIc):
Irrespective of the type of employed amino-functional silicone(s) with terminal hydroxy group(s), the agents as contemplated herein contain the silicone(s) preferably in the form of an emulsion, particularly preferably in the form of a microemulsion.
It has been found that the action of the silicones used in the agents as contemplated herein can be increased still further if specific nonionic components are also used in the agents. In addition, these nonionic components have positive effects on the storage stability of the agents. Nonionic components that are particularly suitable here are ethoxylates of decanol, undecanol, dodecanol, tridecanol, etc. Ethoxylated tridecanols which are incorporated more preferentially into the agents as contemplated herein have proven particularly suitable. Particularly preferred agents as contemplated herein are characterized in that, based on their weight, they contain about 0.00001 to about 5% by weight, preferably about 0.0001 to about 3.5% by weight, particularly preferably about 0.001 to about 2% by weight, more preferably about 0.01 to about 1% by weight, and in particular about 0.1 to about 0.5% by weight of branched, ethoxylated tridecanol (INCI name: Trideceth-5) or α-isotridecyl-ω-hydroxypolyglycol ether (INCI name: Trideceth-10), or mixtures thereof.

Suitable protein hydrolysates are understood to be product mixtures that can be obtained by acid-, base-, or enzyme-catalyzed degradation of proteins.
Protein hydrolysates of plant, animal, and/or marine origin can be used.
Animal protein hydrolysates are, for example, elastin, collagen, keratin, silk, and milk protein hydrolysates, which can also be present in the form of salts. Such products are marketed, for example, under the trademarks Dehylan® (Cognis), Promois® (Interorgana), Collapuron® (Cognis), Nutrilan® (Cognis), Gelita-Sol® (Deutsche Gelatine Fabriken Stoess & Co), Lexein® (Inolex), and Kerasol® (Croda).

The protein hydrolysates underlying the cationic derivatives may be obtained from the corresponding proteins by chemical, in particular, alkaline or acidic hydrolysis, by enzymatic hydrolysis, and/or by a combination of both types of hydrolysis. The hydrolysis of proteins usually gives rise to a protein hydrolysate with a molecular weight distribution of about 100 Da up to several thousand daltons. Preferred cationic protein hydrolysates are those whose underlying protein portion has a molecular weight of about 100 up to about 25,000 Da, preferably about 250 to about 5000 Da. Furthermore, cationic protein hydrolysates are understood to be quaternized amino acids and mixtures thereof. Quaternization of the protein hydrolysates or of the amino acids is often performed by means of quaternary ammonium salts such as, for example, N,N-dimethyl-N-(n-alkyl)-N-(2-hydroxy-3-chloro-n-propyl)ammonium halides. Furthermore, the cationic protein hydrolysates can also be derivatized still further.
