Methods of making emulsions comprising: adding an emulsifying agent comprising glucoside alkyl urethanes of formula:A(O&#x2014;CO&#x2014;NH&#x2014;R),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.

Tensio-active glucoside urethanes

Disclosed are glucoside alkyl urethanes composed of units of the formula: A(O&#x2014;CO&#x2014;NH&#x2014;R)wherein A represents a glucosyl unit of a starch hydrolysate molecule, the starch hydrolysate having a Dextrose Equivalent (D.E.) ranging from 1 to 47, (O&#x2014;CO&#x2014;NH&#x2014;R) represents an N-alkyl aminocarbonyloxy group replacing a hydroxyl group of the glucosyl unit A, and wherein R represents a linear or branched, saturated or unsaturated alkyl group containing from 3 to 22 carbon atoms, and s represents the number of alkyl carbamate groups per glucosyl unit which number is expressed as degree of substitution (DS) with said DS value ranging from about 0.01 to about 2.0 which are useful as surface-active agents. Also disclosed are a method for their manufacture and compositions containing one or more glucoside alkyl urethanes. The glucoside alkyl urethanes have good to excellent tensio-active properties in combination with good biodegrability and they are suitable as surfactants for use in household and industrial applications, e.g., as detergents, emulsifiers, emulsion stabilisers, foaming agents, foam stabilisers, dispersants and wetting agents.
