Abstract
Methods of making emulsions comprising: adding an emulsifying agent comprising glucoside alkyl urethanes of formula:A(O—CO—NH—R)S,wherein A represents a glucosyl unit having a Dextrose Equivalent (D.E.) ranging from 1 to 47, and wherein R represents a linear or branched, saturated or unsaturated alkyl group containing from 3 to 22 carbon atoms, and s is the degree of substitution (DS) ranging from about 0.01 to about 2.0; to an aqueous based liquid and a dispersed product; followed by mixing to create a stable dispersion. The glucoside alkyl urethanes present properties of thermal and chemical stability with biodegradability and free of phosphor/phosphates. The glucoside alkyl urethanes are suitable as surfactants for use in household and industrial applications, e.g., as detergents, emulsifiers, emulsion stabilizers, foaming agents, foam stabilizers, dispersants and wetting agents.
