Alkyl Glycoside-Based Micellar Thickeners For Surfactant Systems

摘要

A rheology modifier which includes a mixture of short and long chain fatty acid esters is suitable for use in liquid surfactant-based compositions. A surfactant-based composition includes a surfactant, the rheology modifier, and water. The rheology modifier includes a mixture of alkyl glycoside fatty acid esters including a long chain fatty acid ester of an alkyl glycoside and a short chain fatty acid ester of an alkyl glycoside. The long chain fatty acid ester includes at least one fatty acid residue: R1(O)O—, wherein R1 is a C12 or higher hydrocarbon. The short chain fatty acid ester includes least one fatty acid residue: R2(O)O—, wherein R2 is a C6-C10 hydrocarbon.

1. A composition comprising:
a surfactant;
a rheology modifier comprising a mixture of alkyl glycoside fatty acid esters comprising:a long chain fatty acid ester of an alkyl glycoside, the long chain fatty acid ester consisting of at least one fatty acid ester group R1(O)O—, wherein R1 is a C12 or higher hydrocarbon, anda short chain fatty acid ester of an alkyl glycoside, the short chain fatty acid ester consisting of least one fatty acid ester group R2(O)O—, wherein R2 is a C6-C10 hydrocarbon; andwater,
wherein a molar ratio of long chain fatty acid ester groups to short chain fatty acid ester groups in the rheology modifier is less than 1:1.
