Abstract
Mixtures comprising at least one alk(en)yl polyglycoside ether carboxylate, and one or more fatty alcohols are described along with methods for preparing the same, wherein a starting mixture comprising (i) at least one alk(en)yl polyglycoside, and (ii) one or more fatty alcohols is provided, and the starting mixture is reacted with a compound selected from the group consisting of ω-halocarboxylic acids, ω-halocarboxylic acid salts, ω-halocarboxylic acid esters, and mixtures thereof.
Claims18
A mixture comprising:
- (a) at least one alk(en)yl polyglycoside ether carboxylate;
- and (b) one or more fatty alcohols, which fatty alcohols consist of C8-C20 alcohols.
A mixture comprising:
- (a) at least one alk(en)yl polyglycoside ether carboxylate, wherein the at least one alk(en)yl polyglycoside ether carboxylate is derived from an alk(en)yl polyglycoside corresponding to the general formula (I):
- R1O-[G]p (I)
- wherein R1 represents an alkyl or alkenyl group having from 4 to 22 carbon atoms, G represents a sugar unit having 5 or 6 carbon atoms and p represents a number of from 1 to 10;
- and
- (b) one or more fatty alcohols, wherein the one or more fatty alcohols consist of a mixture of C16 and C18 alcohols;
- wherein the at least one alk(en)yl polyglycoside ether carboxylate is present in an amount of from 20 to 60% by weight, and the one or more fatty alcohols is present in an amount of from 40 to 80% by weight, based on the mixture.
3 more elements
A process comprising:
- (a) providing a starting mixture comprising (i) at least one alk(en)yl polyglycoside, and (ii) one or more fatty alcohols present in an amount of from 10 to 80% by weight of the starting mixture;
- and
- (b) reacting the starting mixture with a compound selected from the group consisting of ω-halocarboxylic acids, ω-halocarboxylic acid salts, ω-halocarboxylic acid esters, and mixtures thereof.
