Abstract
AbstractStarch heated with a polyol, such as ethylene glycol, propylene glycol, or glycerol, in the presence of an acid catalyst undergoes transglycosidation and forms a mixture of polyol glycosides. This mixture is sufficiently heat‐stable to permit polyetherification with ethylene oxide. The preparation and properties of a number of glycoside polyoxyethylene ethers are described.Nonionic emulsifying agents were prepared by reacting glycoside polyethers with either saturated or unsaturated long‐chain fatty acids and linseed oil. In general, the esterified glycoside polyethers exhibited good emulsifying action, and the unsaturated esters of the polyethers possessed film‐forming properties.
