Branched polymeric emulsifiers

摘要

The present invention relates to esterified glycerylated alkyl glycoside and to a process for making same. The esterified glycerylated alkyl glycoside have one or more polyglyceryl moieties and one or more acyl moieties, wherein all of the one or more acyl moieties are situated on the one or more polyglyceryl moieties via an ester linkage. These compounds have been found to be useful as emulsifiers and coemulsifiers in the formulation of a phase stable emulsions suitable for use in personal care, home care, industrial and institutional, and health care applications.

主权项

1. An esterified branched polyglyceryl ether of an alkyl glucoside having one or more polyglyceryl moieties and one or more acyl moieties, wherein all of said one or more acyl moieties are situated on said one or more polyglyceryl moieties via an ester linkage, wherein said alkyl glucoside is represented by the formula:wherein R represents an alkyl group containing 1 to 22 carbon atoms; GLY is a substituted or unsubstituted glyceryl or polyglyceryl residue represented by the formulae:and combinations thereof, wherein R1 can be the same or different and is selected from hydrogen, an acyl group containing 8 to 54 carbon atoms, and GLY, wherein GLY is as defined above, the sum of v+w+x+y is an integer ranging from about 20 to about 150, subject to the proviso that a portion of R1 represents said acyl group, and wherein the average degree of glyceryl substitution (DSg) on the alkyl glucoside is about 4.
