Cationic guar polymer

U.S. 6649155 (2003) Dunlop et al. (Procter Gamble) 0.02-5% cationic guar gum derivative (mol wt from 50,000 to 700,000, charge density from 0.05 to 1.0 meq/g) 0.1—4% antidandruff particulate (pyridinethione salts, selenium sulfide, or sulfur) nonvolatile conditioning agent Improved coacervate formed between the cationic polymer and anionic surfactant upon dilution of the shampoo superior combination of antidandruff efficacy and conditioning (three-in-one)... 

Cationic polymers such as polymer JR (polyquaternium-10), a quater-nized cellulosic ingredient [6] cationic guar, a quaternized polymer of galactose Merquat polymers (polyquaternium-6 and -7) copolymers of dimethyl diallyl ammonium chloride and acrylamide [7] and Gafquat polymers (polyquaternium-11) (copolymer of polyvinyl pyrrolidone and dimethy-laminoethyl methacrylate) [8] have all been used and are currently used in conditioning shampoos, setting lotions, or mousses.

Anionic galactomannans, which are derived from guar gum, in which the hydroxyl groups are partially esterified with sulfonate groups that result from 2-acrylamido-2-methylpropane sulfonic acid and l-allyloxy-2-hydroxypropyl sulfonic acid [1872], have been claimed to be suitable as thickeners. The composition is capable of producing enhanced viscosities, when used either alone or in combination with a cationic polymer and distributed in a solvent.

Although in pxinciple associative thickenos could be prepared from any water-soluble polymer to which hydrophobic blocks can be attached, only three types are commercially available at present hydrophobe-modified polyfetl lene oxide), hydrophobe-modified alkali-soluble acrylic polymers, and hydrophobe-modified hydroxyethyl cellulose. However, the literature contains reports on other types, including hydrophobe-modified polyacrylamide [103], hydrophobe-modified hydroxypropyl guar [104], and a hydrophobe-modified cationic cellulose... 

A recent patent describes the use of poly(diallylamine)-epichlorohydrin, which is a cationic resin, for crosslinking of nonionic or anionic polymers. This cationic resin has been successfully used to crosslink anionic polymers of cellulose and guar, xanthan gum, and partially hydrolyzed polyacrylamides The nonionic polymers which can be crosslinked with this cationic resin include polyacrylamide,... 

Cationic polymers include homopolymers and cationic copolymers obtained by the polymerization of a vinylic monomer with a quaternary ammonium group or a quatemized amine with another soluble monomer in water such as acrylamide and methacrylamide. The most frequently used polymers are those derived from gum guar such as guar hydroxyl propyl triamonium chloride. They are sold under the trade names Jaguar C13S, C17, etc. [12-16].
