Compositions comprising reaction products of saccharide polymers and fatty acids or fatty esters formulated with an amide-based neutral surfactant

Abstract

Compositions comprising a reaction product of a saccharide polymer and a fatty acid or a fatty ester may be obtained in an aqueous phase in the presence of a hydroxide base and a neutral surfactant, the saccharide polymer comprising a dextran, a dextrin compound, or any combination thereof. The neutral surfactant may comprise at least one compound having a structure of in which Ris a saturated or unsaturated hydrocarbyl group having about 8 to about 30 carbon atoms; Ris C-Coptionally branched alkyl, CHOH, CHO(CHCHO)CHCHOH (x is 0 or a positive integer), CH(OH)CHOH, COH, or CHSO, and Ris H or C-Coptionally branched alkyl, and Rand Rare not simultaneously CHOH and H, respectively. The reaction product of the saccharide polymer may be present in the aqueous phase at a concentration effective to lower a surface tension of the neutral surfactant.
