Foam improvement of soap containing compositions

摘要

The present invention concerns the use of a combination of an amphoteric surfactant and a cationic polymer derivative of polysaccharide to increase the foam volume and foam quality of soap containing compositions. Said advantage may be used to produce cleansing products like cleansing liquid, paste, gel or foam, body shampoo or hair shampoo.

1. Use of a combination of a compound of formula (I) and a cationic polymer derivative of polysaccharide to increase the foam volume and foam quality of a soap containing aqueous composition; said composition comprising at least:
(1) 0.5 to 85% by weight of carboxylic acids having 8 to 24 carbon atoms, and salts thereof; (2) 0.5 to 15% by weight of an amphoteric surfactant of formula (I) as follows:
R1—(CONH)a—(CH2)b—N+(R2)(R3)(R4)Z+  (I) wherein:
a is 0 or 1;b is comprised between 1 and 3;R1 is an alkyl or alkenyl hydrocarbon chain comprising from 7 to 21 carbon atoms;R2 is an alkyl group having 1 to 3 carbon atoms or —(CH2)cOH with c is comprised between 1 and 3;R3 is H, an alkyl group having 1 to 3 carbon atoms, or —(CH2)dCOO− with d is comprised between 1 and 3;R4 is —(CH2)eCOO− with e is comprised between 1 and 3; or —(CH2)fCH(OH)—CH2—SO3− with f is comprised between 1 and 3; andZ is a monovalent cation. (3) 0.01 to 5% by weight of a cationic polymer derivative of polysaccharides; and each components of the composition are expressed in percent by weight in relation with the total weight of the composition.
