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.

Preparation of cationic nanoparticles and personal care compositions comprising said nanoparticles

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.

Polyelectrolyte complexes as thickeners for high ionic strength salt solutions

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.

Polysiloxane block copolymers

A cleaning composition for hard surfaces containing a polymeric compound comprising a main backbone derived from at least the following monomeric components: (I) 20 to 99.9% by weight of at least one cationic monomer according to formula (I) wherein Rand Rare, independently of one another, hydrogen or C-Calkyl; Rand Rare, independently of one another, hydrogen or alkyl, hydroxyalkyl, carboxyl alkyl, carboxyamide alkyl or alkoxyalkyl having from 1 to 18 carbon atoms; and Y represents an anion, and (II) 0.1 to 80% by weight of a hydrophobic unsaturated nonionic monomer that polymerizes in the presence of an initiator; optionally up to 60% by weight of a water-soluble monomer (III) which is different from either monomer (I) or monomer (II); and optionally reactant (IV), a crosslinking agent in an amount between 0 to 10% by weight, gives improved soil removal properties, antimicrobial and biofilm suppression properties as well as resistance to resoiling and staining. 

Hydrophobically modified cationic polymers and their use as cleaning aids

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.

Preparation of functionalized cationic polymers and their application in personal care

The present invention is directed to polymeric compounds comprising a main backbone derived from at least the following monomeric components: (I) 20 to 99.9% by weight, preferably 50% to 99% by weight, of at least one cationic monomer according to formula (I), and (II) 0.1 to 80% by weight of a hydrophobic unsaturated nonionic monomer that polymerizes in the presence of an initiator, optionally a water-soluble monomer (III) different from either monomer (I) and monomer (II), and optionally a crosslinking agent (IV). Said compounds are particularly useful to overcome the problem of dye bleeding and/or dye transfer in laundry processes. 

Hydrophobically modified polymers as laundry additives

A process for the antimicrobial treatment of fiber materials, comprising applying to the fiber material an inclusion complex of a fiber-reactive cyclodextrin derivative with an antimicrobial agent selected from the group consisting of (a) halogeno-o-hydroxydiphenyl compounds or non-halogenated hydroxydiphenyl ether compounds; (b) phenol derivatives; (c) benzyl alcohols; (d) chlorohexidine and derivatives thereof; (e) Calkybetaines and C&#x2013;Cfatty acid amidoaklylbetaines; (f) amphoteric surfactants; (g) trihalocarbanilides; (h) quaternary and polyquaternary compounds; and (i) thiazole compounds.
