The invention relates to a method for improving the foaming and/or yield value properties associated with surfactant containing compositions comprising at least one anionic surfactant, the method comprises combining an effective amount of at least one nonionic, amphiphilic polymer with at least one anionic detersive surfactant in combination with an optional surfactant selected from amphoteric surfactants, nonionic surfactants and combinations of two or more thereof. The at least one nonionic amphiphilic polymer is prepared from a free radically polymerizable monomer composition comprising at least one hydrophilic monomer and at least one hydrophobic monomer, wherein said hydrophilic monomer is selected from a N-vinyl lactam and wherein said hydrophobic monomer is selected from a vinyl ester of a C-Ccarboxylic acid or at least one monomer selected from a C-Calkyl (meth)acrylate an associative monomer, a semi-hydrophobic monomer, or mixtures thereof, and an optional crosslinking monomer.

Foaming performance in cleansing compositions through the use of nonionic, amphiphilic polymers

The present invention provides mild cleansing and cleaning compositions and methods for mitigating irritation induced by harsh detersive surfactants. The invention relates to a method of reducing skin irritation associated with a cleansing composition comprising at least one surfactant, the method comprising combining an effective amount of at least one nonionic amphiphilic polymer with at least one detersive surfactant selected from anionic surfactants, amphoteric surfactants, nonionic surfactants and combinations of two or more thereof. The at least one nonionic amphiphilic irritation mitigating polymer is prepared from a free radically polymerizable monomer composition comprising at least one hydrophilic monomer and at least one hydrophobic monomer, wherein said N-vinyl lactam and wherein said hydrophobic monomer is selected from a vinyl ester of a C-Ccarboxylic acid or at least one monomer selected from a C-Calkyl (meth)acrylate an associative monomer, a semi-hydrophobic monomer, or mixtures thereof.
