Embodiment

[0126] The present invention is further illustrated by the following experiments. These examples are illustrative only and are not intended to limit the scope of the invention in any way.

[0127] Preparation of Hyperbranched Copolymer (HBC1)

[0128] The hyperbranched copolymer HBC1 of the monomers dodecenylsuccinic anhydride and diisopropanolamine and bisdimethylaminopropylamine has been used according to example 3 in EP 2 794 729 B1 using 237.59 g of N,N-bis (N'N'-dimethylaminopropyl)amine was prepared with 112.6 g of diisopropanolamine and 426.89 g of dodecenylsuccinic anhydride. After heating and vacuum, a residual carboxylic acid content 1 H-NMR analysis showed complete conversion of chloroacetate to obtain hyperbranched copolymer HBC1 with end groups of the formula

[0129] And the molecular weight Mn is 2.3 kDa.

[0130] The hyperbranched copolymer HBC1 was used in the following experiments as a 45% aqueous solution.

Abstract

The present invention relates to cosmetic skin care compositions which comprise a hyperbranched copolymer of the monomers dodecenyl succinic acid anhydride, diisopropanol amine and bis-dimethylaminopropyl amine having quaternary terminal groups and at least one non-ionic emulsifier being an ether or an ester of (poly)ethylene glycol.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to the fields of skin care and sun protection. Background technique [0002] In the field of cosmetics, the details of a cosmetic composition, the formulation, are sensitive to texture, sensory and visual aspects. [0003] A big problem is that when such composition materials are applied to a surface, especially the skin, the composition transfers to the other surface when the other surface comes into contact with the composition. Such transfer is negative in two respects: First, transfer of material is undesirable since it is removed from the site of action (eg to treat, moisturize or protect the skin). Secondly, the contact surfaces are contaminated with said material. In particular fabrics, such as clothing, can be stained. Furthermore, decorative or functional surfaces may become contaminated, which is detrimental to the functionality or their visual or aesthetic properties. In part...
