Clear aerosol hair spray formulations containing a linear sulfopolyester in a hydroalcoholic liquid vehicle

Claim 1

A clear aerosol hair spray formulation exhibiting less than 20 NTU's and having a volatile organic content that does not exceed 60 weight percent, wherein the formulation consists essentially of the following ingredients: (1) 0.5 to 15 weight percent of a linear sulfopolyester having a Tg of 40° C. to 50° C. and an inherent viscosity of 0.24 to 0.60 dl/g congaining repeat units consisting essentially of the reaction product of 20 to 26 mole percent dimethyl-5-sodiosulfoisophthalate and 74 to 80 mole percent isophthalic acid, based on 100 mole percent of the dimethyl-5-sodiosulfoisophthalate and isophthalic acid, and 10 to 30 mole percent 1,4-cyclohexanedimethanol and 70 to 90 mole percent diethylene glycol, based on 100 mole percent of the 1,4-cyclohexanedimethanol and diethylene glycol; (2) a water/alcohol liquid vehicle wherein the alcohol is an aliphatic straight or branched chain monohydric alcohol having 2 to 4 carbon atoms; (3) 3 to 40 weight percent based on the weight of ingredients (1), (2), (3) and (4) of a propellant selected from the group consisting of methane, ethane, propane, butane, trichlorofluoromethane, dichlorodifluoromethane, dichlorotetrafluoroethane, monochlorodifluoromethane, trichlorotrifluoroethane, 1,1-difluoroethane, carbon dioxide, nitrous oxide, nitrogen, helium, dimethyl ether, fluorinated oxepane, fluorinated oxetane, and mixtures thereof; and (4) 0.5 to 10 weight percent based on the weight of ingredients (1), (2), (3) and (4) of a water-soluble polymer having a weight average molecular weight of 1,000 to 100,000, which is prepared from at least one vinyl monomer selected from the group consisting of alkyl vinyl ethers, alkyl acrylates, vinyl esters, n-vinyl lactams, alkyl acrylamides, half vinyl esters/half amides, half esters of maleic anhydride vinyl pyrrolidone, acrylic acid, crotonic acid, mathacrylic acid, and combinations thereof.
