Abstract
Abstract The specification describes a hair setting composition comprising as an effective component polyethylene glycol having an average molecular weight of 6,000-30,000. It also describes a hair setting composition comprising as effective components the following ingredients: (A) polyethylene glycol having an average molecular weight of 6,000-30,000 and (B) a divalent or trivalent metal salt of pyrrolidonecarboxylic acid and/or a polyoxyalkylene-added silicone oil. Such hair setting compositions may be formulated into an aerosol type or lotion or pump spray type and facilitates long-lasting hair styling without damaging hair.
