Patent

CA 2395105

The invention provides a fabric softening composition comprising: (i) at least one oily sugar derivative which is a liquid or soft solid derivative of a cyclic polyol or of a reduced saccharide, said derivative resulting from 35 to 100 % of the hydroxyl groups in said polyol or in said saccharide being esterified or etherified, and wherein, the derivative has two or more ester or ether groups independently attached to alkyl or alkenyl chains derived from a fatty acid mixture comprising at least 50 % by weight of a mixture of tallow fatty acid and oleyl fatty acid, and (ii) one or more deposition aid(s). The invention also provides a method of treating fabric by applying thereto the composition of the invention and the use of the aforementioned oily sugar derivatives within a fabric softening composition as a fabric softening aid that does not decrease the absorbency of the fabric. Also provided are the above mentioned oily sugar derivatives.

La présente invention concerne une composition adoucissante pour tissus comprenant (i) au moins un dérivé huileux à base de sucre sous forme liquide ou un solide mou dérivé d'un polyol cyclique ou d'un saccharide réduit, ledit dérivé étant obtenu par estérification ou étherification de 30 à 100 % de groupes hydroxyles dans ledit polyol ou ledit saccharide, et dans laquelle, ledit dérivé présente un ou plusieurs groupes d'esters ou d'éthers liés indépendamment à des chaînes alkyles ou alkényles dérivées d'un mélange d'acides gras comprenant au moins 50 % en poids d'un mélange d'acide gras de suif et d'acide gras oléique; et (ii) un ou plusieurs adjuvants de dépôt. L'invention concerne également un procédé de traitement de tissus par application d'une composition selon l'invention et l'utilisation desdits dérivés huileux à base de sucre au sein d'une composition adoucissante en tant qu'adjuvant adoucissant pour tissu et qui ne diminue pas les propriétés absorbantes du tissu. L'invention concerne en outre lesdits dérivés huileux à base de sucre.
