  • Two-pack type keratinous fiber treating composition
    Patent number: 5750099
    Abstract: A two-pack type keratinous fiber treating composition where the first pack contains an organic solvent and an acid and the second pack contains a cationic polymer and/or an amphoteric polymer. When keratinous fibers are treated with the keratinous fiber treating composition, the cationic polymer and the amphoteric polymer contained in the second pack penetrate into the keratinous fibers which have been swollen by the first pack. Thus, conditioning effects (for example, softness, moistness, smoothness and ease of arrangement of the hair) are exerted on the keratinous fibers for a prolonged period of time.
