ETHOXYLATED POLYURETHANE VISCOSITY ENHANCERS

摘要

The invention provides personal care products comprising fatty ethoxylated dimeric urethane compounds that enhance the viscosity of constituent water based surfactant systems. In compositions and methods of the invention, ethoxylated nonionic, urethane dimers increase the viscosity of water based surfactant systems and serve as thickeners. These thickeners produce clear solutions in combination with surfactants and can be made sufficiently water soluble to produce clear solutions in water. The thickeners are compatible with anionic, cationic, amphoteric and nonionic surfactants and are functional and stable over a wide pH range.
