[0036] The aqueous polyurethane dispersions used in the preparation of the cosmetic compositions according to the invention preferably have a volatile organic compound (VOC) content of less than 10% by weight, more preferably of less than 3% by weight, even more preferably of less than 1% by weight, in which Based on waterborne polyurethane dispersion.

[0037] The volatile organic compound (VOC) content is determined within the scope of the present invention by gas chromatographic analysis.

[0038] The water-insoluble and non-dispersible isocyanate-functional polyurethane prepolymers A1) used according to the invention essentially have neither ionic nor ionogenic groups. Water here refers to deionized water without added surfactant. In the context of the present invention, this refers to polyurethanes in which the proportion of ionic and / or ionogenic (ion-forming) groups, such as anionic groups (such as carboxylate or sulfonate) or cationic groups is less than 15 milliequival...
