Abstract
The present invention relates to personal care compositions, especially hair care compositions, containing hydrophobic, linear random copolymers and a hydrophobic, volatile, branched hydrocarbon solvent for the copolymer. The copolymer is formed by the copolymerization of monomer units that form a homopolymer having a T.sub.g of at least 90.degree. C., and monomer units that form a homopolymer having a T.sub.g of less than 25.degree. C. The hydrocarbon solvent consists essentially of one or more branched chain hydrocarbons containing from 10 to 16 carbon atoms. The invention relates to hair styling and conditioning products such as rinses, leave on conditioners, and combination shampoo products useful for cleansing, styling and conditioning the hair.
