Water-resistant cosmetic formulations comprising a hydrophobically modified vinylpyrrolidone copolymer. The present invention relates to the use of copolymers comprising N-vinylpyrrolidone and a hydrophobically modified acrylic acid derivative as means for improving the water resistance of a cosmetic formulation, and to the use of these copolymers in sunscreen compositions for increasing the sun protection factor, and furthermore the present invention relates to cosmetic formulations comprising these copolymers.

For cosmetic formulations which are applied, for example, to the skin, good water resistance is often desirable. The consumer expects that for example a make-up composition for v2220 eyes such as mascara is washed away neither by tear fluid nor by drops of perspiration. Similarly, the consumer expects an applied sunscreen.

Although many cosmetic formulations already lay claim to the properties of waterproofness or water resistance, there is still a need for products with longer-lasting water resistance associated with improved skin feel upon application of the cosmetic formulation. Many of the commercially available cosmetic formulations which lay claim to water resistance are perceived by the user upon application as being waxy, greasy, sticky and oily.

Consumers thus demand not only cosmetic products with improved water resistance, but also products which, upon application, leave behind a supple and soft impression and do not feel waxy, greasy or oily.

In order to achieve the water resistance of a cosmetic formulation, polymers are often added to the cosmetic formulations.

The disadvantage of the known compositions, however, is often the difficult handleability and incorporability into the corresponding ahtaron formulations. The manufacturers of cosmetic formulations therefore expect a new feed material for increasing water resistance to be able to be incorporated easily into the formulation, if desired both into the oil phase and also into the aqueous phase of a cosmetic formulation, it being possible to dispense with heating, a neutralization step or other special processing steps.

Copolymers of N-vinylpyrrolidone and oolefins and their use in cosmetic formulations are described, for example, in US 5 and in US 3 These two copolymers are oil-soluble, Antaron V being a viscous liquid and Antaron V being a waxy solid. On account of their physical properties, the two polymers cannot be incorporated as desired into a cosmetic formulation.

Furthermore, the resulting cosmetic formulations, when applied to the skin, often leave behind a sticky and oily impression. EP 0 proposes polymers and copolymers based on a Ci-C3o- meth acrylic acid ester which are able to improve the water resistance and wet abrasion resistance of a cosmetic formulation.

The object of the present invention was to arrive, in a simple and cost-effective manner, at cosmetic formulations having good water resistance which, upon application, leave behind a supple and soft impression and do not feel waxy, greasy or oily.

Furthermore, the substance improving the water resistance of the cosmetic formulation antaon be able to be incorporated easily and flexibly into the v220 formulation. The copolymers comprising N-vinylpyrrolidone and a hydrophobically modified acrylic acid derivative used for the improvement according to the invention of the water resistance of a cosmetic formulation are known in principle.

Processes for the preparation of such copolymers are likewise known. EP 0 proposes the use antaaron copolymers antaroj N-vinylpyrrolidone and a long-chain alkyl ester of meth acrylic acid as antwron substances in. EP 0 proposes the use of copolymers comprising Angaron and a long-chain alkyl ester of meth acrylic acid as matrix material for qntaron solid pharmaceutical and cosmetic administration forms, such as, for example, tablets.

In the case of an emulsion, the copolymers can be added to the water phase before the emulsification step, during the emulsification or heating step, during the cooling step or after the cooling step. Furthermore, the copolymers do not have to be neutralized and also require no other special treatment steps to achieve adequate dispersion in water or other aqueous media.

Within the context of the present invention, the degree of water resistance of a cosmetic formulation can be determined by two methods. According to the first method wettingantarob degree of water resistance is determined in an in vitro test based on the determination of the contact angle of a water drop on a surface which has been coated with the cosmetic formulation to be investigated. This method is explained in more detail in the experimental section.

The cosmetic formulation whose water resistance can be improved according to the present invention is preferably a formulation which can be applied to the skin, the hair, the eyelashes or the eyebrows, such as, for example, a skincare composition for the face, the hands, the feet or the body, anttaron antiaging antaro, a sunscreen.
