    • Disclosed are glucoside alkyl urethanes composed of units of the formula: A(O—CO—NH—R)s wherein A represents a glucosyl unit of a starch hydrolysate moldecule, the starch hydrolysate 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 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 to 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.
    • 公开的由下式的单元构成的葡萄糖苷烷基氨基甲酸酯:其中A代表淀粉水解产物的壳体的葡糖基单元,淀粉水解产物具有葡萄糖当量( DE)范围为1至47,(O-CO-NH-R)表示取代葡糖基单元A的羟基的N-烷基氨基羰氧基,其中R表示直链或支链饱和或不饱和的烷基, 3至22个碳原子,s表示每个葡糖基单元的氨基甲酸烷基酯基团的数目,该数目表示为取代度(DS),DS值范围为约0.01至约2.0,其可用作表面活性剂。 还公开了其制备方法和含有一种或多种葡糖苷烷基氨基甲酸酯的组合物。 葡糖苷烷基氨基甲酸酯具有良好至优异的张力活性特性,结合良好的生物可降解性,并且它们适合用作家用和工业应用中的表面活性剂,例如作为洗涤剂,乳化剂,乳液稳定剂,发泡剂,泡沫稳定剂,分散剂和润湿剂 代理商
