Description

"Forming agent for keratin fibers provides strong hold and natural appearance"

The invention relates to the technical field of temporary transformation keratinhaltiger fibers, especially human hair. It relates in particular to hair treatment compositions containing a special polymer combination, the use of these agents for the temporary shaping and / or care of keratin-containing fibers and aerosol sprays or aerosol foams based on these agents.

The first most important property of a composition for the temporary deformation of keratinic fibers, also referred to below as styling agent, is to give the treated fibers in the produced form the strongest possible hold. In addition to a high degree of hold, styling agents must meet a whole range of other requirements. These may be broad in properties on the hair, properties of the particular formulation, e.g. Properties of the foam, the gel or the sprayed aerosol, and properties that affect the handling of the styling agent, are subdivided, with the properties of the hair is of particular importance. Particularly noteworthy are moisture resistance, low tackiness and a balanced conditioning effect. Furthermore, a styling agent should be universally applicable as possible for all hair types.

In order to meet the different requirements, a large number of synthetic polymers has already been developed, which are used in styling agents. The polymers can be subdivided into cationic, anionic, nonionic and amphoteric film-forming and / or setting polymers. Ideally, the polymers yield a polymer film even on a small amount when applied to the hair, which on the one hand gives the hairstyle a strong hold, but on the other hand is sufficiently flexible so as not to break under stress. If the polymer film is too brittle, it results in the formation of so-called Filmpiaken, that is residues that detach during the movement of the hair and give the impression that the user of the corresponding styling agent would dandruff. In addition, the hair coated with a firming polymer often feels harsh.

Furthermore, the temporarily styled hair should look healthy and natural next to the strong hairstyle. The hair shine plays an outstanding role. Often therefore the hair styling agents so-called brighteners are added in sufficient quantity. These brighteners are, for example, oils or gloss pigments such as mica particles. Glossy particles have the disadvantage that they detach with time from the hair and after some time, for example, on the clothing or facial skin again. Oils complain the hair and sometimes lead to a deteriorated adhesion of the film-forming or firming polymers on the hair. This possibly leads to the disadvantage that the imprinted hairstyle can not be fixed by the film-forming or setting polymers over a sufficient duration. The hairstyle hangs faster. The object of the present invention was therefore to provide a means for the temporary deformation of keratin-containing fibers, which is characterized by a high degree of hold, does not matt the keratin-containing fibers and effects good sensor technology of the keratin-containing fibers (in particular a soft hair feel).

It has now surprisingly been found that this can be achieved by a special polymer combination.

A first subject of the present invention is therefore an agent for treating keratin-containing fibers, especially human hair, contained in a cosmetically acceptable carrier

(a) at least one anchoring anionic copolymer comprising at least one structural unit of the formula (I) and at least one structural unit of the formula (II) and at least one structural unit of the formula (III)

wherein

R is a hydrogen atom or a methyl group,

R ² represents a hydrogen atom or a methyl group

R ³ is a branched (C ₁ to C ₂ o) -alkyl group, a branched (C ₂ to C ₆ ) -

Hydroxyalkyl group or a group ^* - (CH ₂ CH ₂ O) _n -R ⁶ where R ⁶ = branched (C 1 to C ₂₀ ) -alkyl and n = 1 to 30,

R ⁴ and R ⁵ are each a hydrogen atom or one of the two radicals

Hydrogen atom and the other for a methyl group, and at least one polymer comprising at least one structural unit of the formula (M1)

According to the above formulas and all the following formulas, a chemical bond marked with the symbol ^{* stands} for a "free valence" of the corresponding structural fragment, to which "free valence" bind further structural fragments in the corresponding copolymer. These are previously described and optionally further structural fragments of the respective polymer. Firming polymers contribute to the maintenance and / or build-up of the hair volume and hair fullness of the overall hairstyle. These polymers are at the same time also film-forming polymers and therefore generally typical substances for shaping hair treatment agents such as hair fixatives, hair foams, hair waxes, hair sprays. The film formation can be quite selective and connect only a few fibers. As a test method for the firming effect of a polymer, the so-called curl retention test is often used.

Film-forming polymers are polymers which leave a continuous film on the skin, the hair or the nails when drying. Such film formers can be used in a wide variety of cosmetic products, such as for example face masks, make-up, hair fixatives, hair sprays, hair gels, hair waxes, hair treatments, shampoos or nail varnishes. Particular preference is given to polymers which have a sufficient solubility in water or water / alcohol mixtures in order to be present in completely completely dissolved form in the agent according to the invention. The film-forming polymers may be of synthetic or natural origin.

According to the invention, film-forming polymers are understood as meaning polymers which, when used in 0.01 to 20% strength by weight aqueous, alcoholic or aqueous-alcoholic solution, are capable of depositing a transparent polymer film on the hair.

For the purposes of the invention, "crosslinked" or "crosslinking" is the linking of polymer chains to one another by covalent chemical bonding to form a network. This covalent linkage of the polymer chains takes place through a bridging polysiloxane molecule fragment. The cross-linking polysiloxane molecule fragment binds to the polymer chains bridged by the molecule fragment, each by means of covalent chemical bonding.

According to the invention, an anionic polymer is understood as meaning a polymer which, in standard conditions, contains structural units with anionic groups which have to be compensated by counterions while maintaining the electroneutrality in a protic solvent and has no structural units with permanently cationic or cationizable groups. Anionic groups include carboxyl and sulfonic acid groups.
