Abstract: Disclosed are compositions for washing, cleansing, and/or rinsing keratin substrates, comprising: (a) an ampholytic polymer comprising a repetition of: (i) one or more units obtained from a monomer of (meth)acrylamide type, (ii) one or more units obtained from a monomer of (meth)acrylamidoalkyltrialkylammonium type, and (iii) one or more units obtained from an acidic monomer of (meth)acrylic acid type; (b) a copolymer comprising a monomer (i) selected from acrylic acid amide, methacrylic acid amide, N-alkylacrylic acid amide and N-alkyl-methacrylic acid amide; a monomer (ii) selected from N-vinyllactams and N-vinylpyrrolidone; a monomer (iii) selected from quaternized N-vinylimidazoles; and the monomer N-vinylimidazole; (c) a silane; (d) a surfactant mixture; and (e) water. Also disclosed are processes for washing, cleansing, and/or rinsing keratin substrates using the composition, and processes for imparting instant and long lasting volume as well as conditioning to the keratin substrates.
