Abstract
The present invention relates to methods for using polymeric suds enhancers (stabilizers) to increase the suds and/or foam volume and suds and/or foam retention in suds-forming and/or foam-forming compositions comprising such polymeric suds stabilizers. Suitable suds-forming and/or foam-forming compositions comprise one or more polymeric suds stabilizers. The polymeric suds stabilizers suitable for use in the methods and/or compositions of the present invention comprise cationic, anionic, and noncharged monomer units, or units having mixtures thereof, wherein said polymers have an average cationic charge density from about 0.05 to about 5 units per 100 daltons molecular weight at a pH of from about 4 to about 12.
