Abstract: The use of N-vinyl-pyrrolidone (NVP) copolymers (I) is claimed as surfactants in formulations of water-insoluble materials (II). (I) is derived from (a) 60-99 mol.% NVP, (b) 1-40 mol.% of one or more monomer(s) selected from (b1) 8-30C alkyl esters of mono-ethylenically unsaturated 3-8C carboxylic acids, (b2) N-(8-18C alkyl)- or N,N-di-(8-18C alkyl)-substituted (meth)acrylamides and (b3) vinyl esters of 8-30C aliphatic carboxylic acids and (c) 0-39 mol.% of further radically copolymerisable monomers. The (II) formulations containing (I) as surfactant are also claimed.
