Description

"Spray for elastic and lasting hold"

The invention is in the technical field of forming and fixing the shape of keratin-containing fibers, in particular human hair. In principle, all animal hairs, e.g. Wool, horsehair, angora hair, furs, feathers and products or textiles made from them. Preferably, however, according to the invention, the keratin fibers are human hair.

The use of polymers in various cosmetic products is widespread. They are found in skin treatment agents as well as in hair treatment agents, in agents that are washed off or washed off immediately after use, so-called rinse-off products, as well as in skin or skin care products Hair remains, so-called leave-on remedies. The polymers are used for various reasons and in each case exploited certain properties of the polymers. In agents for skin treatment, in shampoos, hair conditioners and hair treatments, the thickening or care properties of the polymers are often in the foreground. In means for the temporary deformation of keratinous fibers, hereinafter also referred to as styling agents, in addition to these properties, above all film-forming and / or strengthening effects are required. Often polymers also serve as an aid to improve the deposition and fixation of other active ingredients and ingredients on the skin or hair or make it possible. Thus, for example, by adding suitable polymers to hair dyes, the rubbing fastness and the stability of the dyeing can be increased.

In the case of styling agents, it is necessary for the polymers used to give the treated hair the strongest possible hold. However, in addition to a high degree of hold, styling agents must meet a whole range of other requirements. These may be broadly subdivided into properties on the hair, properties of the particular formulation, eg properties of the foam, of the gel or of the sprayed aerosol, and of properties relating to the handling of the styling agent, the properties of the hair being 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. Pump sprays contain a higher proportion of water than aerosol sprays. The firming polymers applied by a pump spray often give a good initial hold, but in particular decreases at higher humidity. In addition, it has been found that the carboxylate-based anionic polyester-polyurethane polymers increasingly used in pump sprays are in need of improvement in terms of durability and flexibility.

The object of the present invention was therefore to provide a cosmetic agent which gives keratin-containing fibers, especially human hair, very good support, without having to sacrifice flexibility and good moisture resistance - in particular sweat and water resistance.
