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:
High molecular weight, crosslinked, water-soluble cationic polymers, such as poly(diallyldialkyl ammonium) halides, give superior performance to conventional polymers in hair care applications, particularly as conditioning agents for hair together with or after a beautification treatment such as relaxing, waving, perming, coloring, straightening or bleaching.
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.
Abstract:
Water-soluble functionalized cationic copolymers obtainable by a process which comprises reacting a cationic base polymer which contains amino groups with at least one functional compound reactive to at least a part of the amino groups on the base polymer, are useful in personal care and cosmetic formulations.
Abstract:
The present invention is directed to cationic nanoparticles, methods to make them, and the use of compositions containing said nanoparticles in personal care compositions or formulations. The nanoparticles are useful in personal care applications and impart antimicrobial properties to home and personal care products containing them. These cationic nanoparticles also contribute useful conditioning properties to hair-care and skin-care products.
Abstract:
Described is a process for the incorporation of an antimicrobial agent into a non-woven comprising treating the nonwoven with a formulation comprising (a) an antimicrobial agent selected from (a1) halogeno-o-hydroxydiphenyl compound; (a2) phenol derivative; (a3) benzyl compound; (a4) chlorohexidine and a derivative thereof; (a5) C12-C14alkylbetaine and C8-C18fatty acid amidoalkylbetaine; (a6) an amphoteric surfactant; (a7) trihalocarbanilide; (a8) quaternary and polyquaternary compound; and (a9) a thiazole compound; and (a10) a iodine containing agent; (a11) a naphthyl derivative; (b) a solubilizing agent; and optionally (c) at least one copolymer made from two or more monomers, with at least one monomer having good affinity to the textiles and at least another monomer having affinity to the involved antimicrobial substances. Nonwovens finished according to the present process have long lasting antimicrobial efficacy and are advantageous with respect to inhibition of micro-organisms, reduction of the risk of contamination, reduction of odor, increase in freshness and improvement in hygienic conditions.

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.
