CA 2590707

A rinse-added fabric enhancer composition has from about 0.01% to about 10% of a cationic polysaccharide polymer, from about 0.1 to about 50% of an anionic surfactant, and the balance adjunct ingredients. The cationic polysaccharide polymer has a weight average molecular weight of from about 400 g/mol to about 2,000,000 g/mol and a calculated charge density of from about 1% to about 50%, while the anionic surfactant has an alkyl chain having from about 6 to about 22 carbon atoms. The cationic polysaccharide polymer and the anionic surfactant undergo associative phase separation such that when the fabric enhancer composition is diluted with water at a ratio of water : fabric enhancer composition of 500:1, minimum transmittance is achieved within about 10 minutes.

L'invention concerne une composition d'amélioration des tissus, à ajouter au rinçage, comprenant environ 0,01 % à environ 10 % d'un polymère de polysaccharide cationique, environ 0,1 à environ 50 % d'un agent tensio-actif anionique, le reste étant constitué par des ingrédients formés par des ajouts. Le polymère de polysaccharide cationique présente un poids moléculaire moyen en poids d'environ 400 g/mol à environ 2.000.000 g/mol et une densité de charge calculée d'environ 1 % à environ 50 %, cependant que l'agent tensio-actif anionique présente une chaîne alkyle d'environ 6 à environ 22 atomes de carbone. Le polymère de polysaccharide cationique et l'agent tensio-actif anionique subissent une séparation de phase associative, telle que lorsque la composition d'amélioration des tissus est diluée avec de l'eau, dans un rapport : eau : composition d'amélioration des tissus de 500 :1, un minimum de transmittance est obtenue au bout d'environ 10 minutes.
