Personal care compositions with ethylene acrylic acid copolymer aqueous dispersions
WIPO Patent Application WO/2011/156579
Publication date: Dec. 15, 2011
Assignee: Union Carbide Chemicals & Plastics Technology LLC and S. Jordan
Described in this patent are personal care compositions comprising an aqueous dispersion including an ethylene acrylic acid copolymer, and a least one cosmetically acceptable surfactant, emollient or cosmetic active. According to this invention, while cationic polymers are known to provide conditioning benefits, they tend to build up on hair and cause limp and/or unmanageable hair. Other conditioning agents containing oily (silicone) or waxy (fatty acids) material are known but have several drawbacks, including the proclivity of silicones to wash off the hair when paired with surfactants.
