Tensio-active glucoside urethanes

A method for making a stable emulsion of an aqueous based liquid and a dispersed product by the addition of at least one emulsifying agent, which comprises supplying an emulsifying agent which comprises a glucoside alkyl urethane (I), which is composed of units of formula (II)

• A(O—CO—NH—R)S (II)
• wherein
• A represents a glucosyl unit of a starch hydrolysate molecule, wherein the starch hydrolysate is one having a Dextrose Equivalent (D.E.) ranging from 1 to 47,
• (O—CO—NH—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 a DS value ranging from about 0.01 to about 2.0 in solution;
• wherein the emulsifying agent is added in an amount of 0.001% to 5% (% w/v);
• and
• mixing the aqueous based liquid, dispersed product and the emulsifying agent to create a stable dispersion.
