Abstract
Provides hair conditioning shampoo compositions suitable and safe for frequent (e.g., daily) use and contact with the hair and skin, said compositions comprising: (a) one or more detersive surfactants such as those selected from the group consisting of anionic, nonionic, amphoteric, and zwitterionic surfactants;(b) a nonvolatile hair conditioning agent or combination of nonvolatile hair conditioning agents selected from the group consisting of insoluble silicones, water soluble organic cationic conditioning agents such as cationic surfactants and cationic polymers; and (c) from about 20% to about 99.5%, by weight, water; wherein said composition additionally comprises from about 0.004M to about 0.08M of free polyvalent metal cations. The present invention can provide improved consistency of deposition on the hair for nonvolatile, insoluble silicone and water soluble cationic conditioning agents when the composition is applied using water across a broad range of hardness.
