Abstract
Amine functionality-containing materials such as cationic cellulose-based compositions are coated to suppress their tendency to generate "amine odors" in an alkaline pH environment. Further provided are effervescent compositions, liquid or solid soap formulations, fabric softeners, shampoos and the like comprising such materials coated with a suitable coating composition.
Claims14
A coated amine functionality-containing composition comprising 0.01-10% by weight, based on the total weight of the composition, a polymer comprising quaternary ammonium groups, said polymer in particulate form being coated with a water-soluble coating composition comprising at least one water-soluble coating agent selected from the group consisting of water-soluble long chain non-ionic surfactants free of amine functionalities, water-soluble polymers selected from the group consisting of polyethyleneglycol, polypropyleneglycol, polyvinylpyrrolidone, polysaccharides, starches, gums, hydroxyethyl cellulose, hydroxypropyl cellulose and mixtures thereof, and wherein said water-soluble coating composition has a melting point lower than that of said polymer comprising quaternary ammonium groups the composition further comprising at least one other suitable material selected from the group consisting of carbonate salts, cosmetic oils, organic acids, fillers, fragrances, inorganic acids, vitamins, crude drugs, natural dyes, artificial dyes, pigments and cosmetic powders.
