Abstract: A polyelectrolyte complex composition capable of viscosifying or thickening an aqueous high salt-containing system comprises a mixture of at least one anionic polymer and at least one cationic polymer in an inorganic salt-containing aqueous medium. The anionic polymer and cationic polymer can each be linear and water-soluble, crosslinked and water-soluble, or crosslinked and water-insoluble or swellable.

Abstract: This invention encompasses novel amphiphilic block copolymers comprising polysiloxane blocks and polycationic blocks. The polycationic blocks are formed from diallyldialkylammonium derivatives. The formed block copolymers are particularly useful for treating or conditioning keratinous substances such as hair or skin.

Abstract: A microgel is produced by a two-stage process wherein the monomers are first polymerized in the absence of solvent for a controlled period, and in a second stage solvent is added and polymerization is completed. The polymer is preferably a polyurethane formed from a polyalkylene glycol, a triol and a diisocyanate. The molecular weight is typically 100,000 to 200,000. The microgels form granules which may be compressed into solid form. Such solid forms containing an active agent, such as a protein, are useful as sustained delivery devices.
