Abstract: Disclosed are hair conditioning compositions which provide cleaner hair conditioning than is experienced with traditional hair conditioners based on quaternary ammonium compounds and lipid materials. The present conditioning compositions are based on a substantially non-depositing vehicle base which comprises a primary thickening agent which is a nonionic long chain alkylated cellulose ether, a secondary thickening agent which is a water-insoluble surfactant, and a compatible solvent. These compositions comprise a mixture of conditioning agents including silicone conditioning agents, cationic surfactant conditioning agents, and high levels of fatty alcohol conditioning agents. These conditioning compositions provide optimized hair conditioning without the drawbacks associated with traditional hair conditioners, that is, dirty hair feel and quick resoiling of hair.
