Alkoxylated sucrose esters composition

摘要

Purified alkoxylated sucrose esters of the formula:;
wherein R is independently selected from: COR′; (CH2CH2O)xH; and (CH2CH2O)x COR′; wherein R′ is a fatty acid compound having from about 2 to about 28 carbon atoms; and wherein x is a number selected from about 1 to about 50; wherein at least one of the R groups is an ester group that is directly esterified to the sucrose backbone; and wherein the alkoxylated sucrose ester composition further comprises: less than 1% aldehydes; less than 1% ketones; less than 1% benzyl halide; less that 1% mono-benzyl ether; less than 1% acetals; and less than 1% ketals.
