    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.
