  • Hair care compositions
    Patent number: 6749836
    Abstract: A latex composition for hair care containing a spray-dried hybrid-graft copolymer of a sulfopolyester and an acid-functional polymer segment. The acid-functional polymer segment is formed from at least one acid-functional monomer, at least one ethylenically unsaturated monomer, and at least one amide-containing monomer. Such compositions exhibit superior curl retention even at high humidity.
    Type: Grant
    Filed: October 23, 2000
    Date of Patent: June 15, 2004
    Assignee: Eastman Chemical Company
    Inventors: Robert Gow-Sheng Chen, Phillip Michael Cook, Ramesh Chand Munjal
