Abstract
Disclosed is an anionic shampoo-conditioning composition comprising an oily conditioning agent, a shampooing agent, a carboxyvinyl polymer, a cationic conditioning agent, and water. The carboxyvinyl polymer has a large proportion of carboxyl monomeric groups and a small proportion of long-chain alkyl monomeric units, and is crosslinked to a small degree. Further disclosed is a process for making the above composition and a method for applying it to hair. The composition provides enhanced conditioning properties utilizing both oily and cationic conditioning agents in combination with an anionic carboxyvinyl polymer while maintaining stability and dispersion.
