  • Patent number: 5756447
    Abstract: A cleaning composition contains (a) a detersive surfactant and (b) a poly(amino acid) compound or a precursor thereof, the said component (b) being protected from contact with a level of alkalinity as would cause degradation thereof. The component (b) may be stabilized by, for example, coating it with an organic acid compound or with a film-forming polymer; by agglomerating it with a controlled level of alkaline or alkaline-reacting compound (e.g. sodium carbonate); by spray-granulating it in admixture with a nonionic surfactant; by encapsulating it with a silicone-based resin; or by incorporating it in a composition that is non-alkaline. The storage stability of the compositions is thereby improved.

  • Patent number: 5756436
    Abstract: Disclosed are aqueous conditioning shampoo compositions which comprise an anionic detersive surfactant component; dispersed, liquid, droplets of a water insoluble, hair conditioning agent having a number average particle diameter of from about 0.01 microns to about 2000 microns; from about 0.025% to about 5% by weight of an organic, cationic, non crosslinked, deposition or conditioning polymer having a cationic charge density of from about 4 meq/gm to about 7 meq/gm and an average molecular weight of from about 1,000 to about 1 million. The cationic polymer, in combination with anionic detersive surfactant component and other essential components, provides improved deposition of the conditioning agent on hair or skin, even when the dispersed conditioning agent particles have a number average particle size of up to about 2,000 microns. The composition may be applied to skin or hair, and provides improved conditioning performance even without the use of the dispersed hair conditioning agent particles.
