    Abstract: A copolymer consisting of the following monomers is used as a solubilizing agent: (a) 5-99 wt.% of at least one N-vinyl carboxamide (I), (b) 1-95 wt.% of at least one monomer with a hydrophobic group, and (c) 0-94 wt.% of at least one other comonomer. A copolymer consisting of the following monomers is used as a solubilizing agent: (a) 5-99 wt.% of at least one N-vinyl carboxamide of formula (I), (b) 1-95 wt.% of at least one monomer with a hydrophobic group, and (c) 0-94 wt.% of at least one other comonomer. R , R = H or 1-6C alkyl. Independent claims are also included for the following: (1) a composition containing at least one water-insoluble ingredient and at least one copolymer as above; (2) use of the copolymer as a protective colloid, especially for stabilizing oil-in-water emulsions.

    Abstract: A cosmetic composition comprising water-soluble copolymer, which as characteristic structural elements comprisesa) vinylcarboxamide units of the general formula IwhereR1 and R2 independently of one another are H, alkyl, cycloalkyl, aryl or aralkyl, andb) units of the general formula IIwhereA is a chemical bond or an alkylene group,the radicals R3 independently of one another are H, alkyl, cycloalkyl, aryl or aralkyl, or together with the nitrogen atom to which they are bonded, form an unsubstituted, mono- or polysubstituted, five- to seven-membered, heterocyclic, aromatic or nonaromatic ring, which if appropriate contains one or two further heteroatoms, selected from among O, N and S, it being possible for the heterocyclic ring to be fused to a further five- or six-membered, aromatic or nonaromatic ring,R4 is H, alkyl or aralkyl.
