Abstract
A hair fixative composition includes at least one carboxylated cellulose ether based polyglucose polymer, an alcohol based solvent system, and a cosmetically acceptable additive, wherein the polyglucose polymer is soluble in the alcohol based solvent system. The polyglucose polymer is obtained by reacting at least one cellulose ether with at least one anhydride.
