Description

"Means and Method of Temporarily Deforming Keratinous Fibers"

The present invention relates to a cosmetic composition for the hair setting or for the temporary reshaping of keratinic fibers, in particular human hair, wherein the composition contains a combination of two anionic acrylate polymers.

The temporary design of hairstyles for a longer period of time to several days usually requires the application of firming agents. Therefore, hair treatment agents which serve a temporary shaping of the hair, play an important role. Corresponding temporary deformation agents usually contain synthetic polymers and / or waxes as the setting agent. Means for supporting the temporary shaping keratinhaltiger fibers can be formulated for example as a hair spray, hair wax, hair gel, hair foam.

The most important property of a hair temporary deformation agent, hereafter called a styling agent, is to treat the treated fibers in the newly modeled form - i. a form imprinted on the hair - to give as strong a hold as possible. One also speaks of strong hairstyle or the high degree of hold of the styling means. The hairstyle stop is in

Essentially determined by the nature and amount of the setting agents used, but also an influence of the other components of the styling agent may be given.

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 tack and a balanced conditioning effect. Furthermore, a styling agent should be universally applicable for all hair types and mild to hair and skin.

In order to meet the different requirements, a variety of synthetic polymers have been developed as setting agents, which are used in styling agents. The polymers can be solidified in cationic, anionic, nonionic and amphoteric

Divide polymers. Ideally, when applied to hair, the polymers give a polymer film which, on the one hand, gives the hairstyle strong hold but, on the other hand, is sufficiently flexible 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. Similar problems arise when waxes are used as a firming agent in the styling agent

Find. If the styling agent is a gel or a paste, the polymers should also have thickening properties. Known anionic polymers used in hair fixation products are acrylate copolymers having two or more structural units. Certain such copolymers having the INCI name Acrylates / Steareth-20 Methacrylate Copolymer as a component of hair cosmetic compositions for temporary hair deformation are described in European Patent EP 897 71 1 B1.

Other such copolymers with the INCI nomenclature Acrylates / beheneth-25 methacrylate copolymer and their use in cosmetic compositions for the temporary deformation of keratinous fibers, are described in the German patent application DE 10 2008 038 105 A1.

Furthermore, hydrophobically modified acrylate copolymers (INCI: Acrylates Copolymer (and) Water) are commercially available, which act essentially as a thickener. The data sheet Aquastyle SH ^® 100 polymer (Ashland Inc.) describes such an acrylate copolymer and its use in combination with carbomers. It will be a good match for crystal clear hair gels

Initial stiffness, moisture resistance and a long-term effect described.

An object of the present invention was to provide other suitable polymer combinations which are characterized by good film-forming and / or setting properties, have a very high degree of hold without compromising on flexibility and good

Moisture resistance - in particular sweat and water resistance - would have to be waived and also for the production of stable viscous and stable transparent cosmetic

Compositions are suitable. In particular, currently available styling agents can be improved to the extent that a good combination of stiffness (Stiffness) and long-term (High Humidity Curl Retention) is not always sufficiently guaranteed. It is therefore an object of the present invention to provide such styling agents which, in addition to the abovementioned properties, result in particular both good rigidity and good long-term maintenance.

Hair foam or hair wax. Preference is given to the preparation as a hair gel.

Both hair mousses and hair sprays require the presence of leavening agents.

According to the invention, however, preferably no or only small amounts of

Hydrocarbons are used. Propane, propane / butane mixtures and dimethyl ether are particularly suitable blowing agents according to the invention.

The present invention also relates to the use of cosmetic compositions according to the invention for the temporary reshaping of keratinic fibers, in particular of human hair, as well as a method for the temporary deformation of keratinic fibers, in particular human hair, in which the cosmetic composition according to the invention is applied to keratinic fibers.

A further subject of this patent application is the use of a cosmetic composition according to the invention for improving the moisture resistance of temporarily deformed keratinic fibers.

Examples

1 . The following hair gels were produced:

30% by weight of active substance in water

The quantities in the table are given in wt .-% of the respective raw material, based on the total composition. The polymer content in each of the compositions V1, V2 and E1 was 1.0% by weight.

For the resulting styling agents, the moisture resistance was determined by means of an HHCR test (High Humidity Curl Retention Test: 6 h) on new Kerling hair strands (average when determined on 5 hair strands each):

The polymer combination E1 according to the invention therefore showed a clearly superadditive, synergistic effect in terms of moisture resistance.

2. The following hair gels were prepared:

20% by weight of active substance in water

30% by weight of active substance in water The quantities in the table are given in wt .-% of the respective raw material, based on the total composition.

For the resulting styling agents, the moisture resistance was determined by means of an HHCR test (High Humidity Curl Retention Test: 6 h) on purified Kerling hair strands (mean value determined on 5 hair strands each):
