Abstract
The present invention then concerns a fabric softener composition that performs well on softening fabrics, which comprises a blend of amphoteric surfactant carrying a C12-C22-alkyl or C12-C22-alkenyl, a fatty acid or a fatty alcohol, and a polysaccharide or polysaccharide derivative. The invention also concerns the use of said softening composition to impart fabric softness to fabrics.
Claims5
A method for softening a fabric comprising the step of contacting an aqueous medium comprising a softening composition with a fabric during a rinse cycle of a fabric washing machine, the softening composition comprising at least:
- a) 1-10% wt of a betaine having the structure:
- R1R2R3N+(CH2)yC(O)O− (I)
- wherein R1 is methyl, R2 is a C16-alkyl, R3 is methyl, and y is 2;
- b) 0.1-5% wt of an alcohol compound carrying a C14-alkyl;
- the weight ratio of compound a) to compound b) is comprised between 1:2 and 20:1;
- c) 0.01-2% wt of hydroxypropyl guar hydroxypropyltrimonium chloride;
- the weight ratio of compound a) to compound c) is comprised between 3:1 and 30:1;
- and
- d) water;
- wherein the percent by weight is expressed in relation with the total weight of the softening composition.
