  • Patent number: 6007794
    Abstract: This invention relates to an aerosol hair spray formulation containing 0.5 to 15 weight percent of a water-dispersible or water-dissipatible, linear sulfopolyester having a Tg of 40.degree. C. to 50.degree. C. and an inherent viscosity of 0.24 to 0.60 dl/g which contains repeat units from 20 to 26 mole percent dimethyl-5-sodiosulfoisophthalate and 74 to 80 mole percent isophthalic acid, based on 100 mole percent dicarboxylic acid; 10 to 30 mole percent 1,4-cyclohexanedimethanol and 70 to 90 percent diethylene glycol, based on 100 mole percent diol; and up to 60 weight percent of an alcohol. The aerosol hair spray formulations are clear, have improved dry time and curl retention, and exhibit less than 20 NTU's, which is a measure of turbidity, even at high concentrations of alcohol.

  • Patent number: 5660816
    Abstract: A clear hair spray formulation which exhibits less than 30 NTU's and contains a linear sulfopolyester and a water-soluble polymer wherein the formulation is in water or a water/alcohol mixture. The sulfopolyester has a glass transition temperature of 40.degree. C. to 60.degree. C. and contains repeat units from the reaction product of a dicarboxylic acid, a diol and a difunctional sulfomonomer. The difunctional sulfomonomer is present in an amount from 18.5 to 22.5 mole percent based on 100 mole percent dicarboxylic acid and 100 mole percent diol. The hair spray formulation may optionally contain a propellant.

  • Patent number: 5320836
    Abstract: This invention relates to hair spray formulations which eliminate flaking. The hair spray formulations are based on (1) a sulfonate-containing, water-dispersible or water-dissipatible, linear polyester having a glass transition temperature of 33.degree. C. to 60.degree. C., (2) a polyethylene glycol ester of a mixture of caprylic and capric acids, (3) an alpha-hydroxy carboxylic acid having 2 to 6 carbon atoms, and (4) water or a water/alcohol mixture.

    Assignee: Eastman Kodak Company
    Inventor: Andy H. Singleton
  • Patent number: 5266303
    Abstract: This invention relates to aerosol hair spray formulations based on (1) a sulfonate-containing, water-dispersible or water-dissipatible, linear polyester having a glass transition temperature of about 36.degree. C. to about 40.degree. C. and (2) a water-soluble, polyvinyl lactam polymer. In addition, the formulations contain water as the liquid vehicle and a propellant. Such aerosol hair spray formulations do not contain any volatile organic compounds other than propellant yet exhibit fast drying times and excellent performance characteristics.
