Example Embodiment

[0036] The aqueous polyurethane dispersion used in the preparation of the cosmetic composition according to the present invention preferably has a volatile organic compound (VOC) content of less than 10% by weight, more preferably less than 3% by weight, and even more preferably less than 1% by weight. Aqueous polyurethane dispersion is the basis.

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

[0038] The water-insoluble and non-aqueous-dispersible isocyanate-functional polyurethane prepolymer A1) used in accordance with the invention basically has neither ionic groups nor ion source groups. The water here refers to deionized water without added surfactant. In the context of the present invention, this means that the ratio of ion and / or ion source (ion forming) groups, such as anionic groups (such as carboxylate or sulfonate) or cationic groups, is less than 15 meq / 100g of polyurethane ...

Description

technical field [0001] The present invention relates to a cosmetic composition comprising polyurethane and its use in hair styling. Background technique [0002] Both human and animal hair are keratin fibers. Compositions for styling hair are a class of cosmetic compositions which can be used to style and stabilize different hairstyles. Hair styling compositions mainly take the form of styling mousses or hairsprays. Styling mousses and hairsprays differ little in their composition, but differ in their application. A styling mousse is applied to damp hair as an aid to modeling the hairstyle. In contrast, hairsprays are sprayed onto dry styled hair to set the style. In addition to hairsprays and styling mousses, it also comes in the form of hair styling gels. [0003] In the case of hairsprays and styling mousses, the fixative or styling composition used for the hairstyle is usually in the form of a formulation that can be sprayed from an aerosol container, squeezed from ...
