Abstract
The present disclosure provides an oil-in-water (O/W) emulsifier comprising esters of polyglycerol-6 and of fatty acids, and of polyglycerol-X, wherein X is any one of 4, 5 and 7 to 12 and of fatty acids, wherein the fatty acids are liquid fatty acids having a purity of at least 85% w/w, wherein the polyglycerols have a purity of at least 60% w/w, and wherein the emulsifier can form a stable O/W emulsion for at least 1 week at about 50° C. It also provides a method for making the emulsifier and emulsions comprising the emulsifier.
Claims23
An oil-in-water (O/W) emulsifier consisting essentially of esters of polyglycerol-6 and of a C12-C14 fatty acid, and of polyglycerol-X, wherein Xis any one of 4, 5 and 7 to 12 and of the C12-C14 fatty acid,
- wherein the esters were prepared by mixing the polyglycerol-6 and the polyglycerol-X prior to esterification with the C12-C14 fatty acid,
- wherein prior to mixing the C12-C14 fatty acid with the polyglycerols, the C12-C14 fatty acid has a purity of at least 85% w/w, and the polyglycerols have a purity of at least 60% w/w, and
- wherein the emulsifier can form a stable O/W emulsion for at least 1 month at about 50° C., and wherein the emulsifier is liquid at about 20° C. to about 30° C.
A method of preparing an oil-in-water (O/W) emulsifier comprising:
- (a) heating polyglycerol-6, polyglycerol-X, wherein X is any one of 4, 5 and 7 to 12, and a C12-C14 fatty acid at about 70° C. to about 110° C. to form a mixture, wherein prior to mixing the C12-C14 fatty acid with the polyglycerols, the polyglycerols have a purity of at least 60% w/w, and the C12-C14 fatty acid has a purity of at least 85% w/w;
- and
- (b) esterifying the mixture at a temperature between about 120 and about 170° C., wherein the O/W emulsifier consists essentially of esters of the polyglycerol-6 and of the C12-C14 fatty acid, and of polyglycerol-X and of the C12-C14 fatty acid;
- and the emulsifier can form a stable O/W emulsion for at least 1 month at about 50° C., and wherein the emulsifier is liquid at about 20° C. to about 30° C.
