CA 2608541

A liquid fabric treatment composition comprising a cationic fabric softening agent and a water-soluble linear polymeric viscosity modifier represented by the formula: Z-Y-(X-Y)n -Z in which: X represents a polyether chain, each Y independently represents a linking group derived from a diisocyanate, each Z independently represents a hydrophobic group and optionally includes a spacer linked to Y, n represents an integer of at least 2, and the molecular weight of the polymer is from 2,000 to 80,000.

L'invention concerne une composition liquide pour le traitement de tissus, comprenant un adoucissant cationique pour tissus et un modificateur de viscosité linéaire, polymérique et hydrosoluble, représenté par la formule : Z-Y-(X-Y)n-Z, dans laquelle : X représente une chaîne polyéther, chaque Y représente indépendamment un groupe de liaison dérivé d'un diisocyanate, chaque Z représente indépendamment un groupe hydrophobe et inclue éventuellement un espaceur lié à Y, n représente un entier d'au moins 2, et la masse moléculaire du polymère est comprise entre 2 000 et 80 000.
