Abstract
Compositions of matter comprising benzoate esters of hydroxyl terminated polyether polysiloxane copolyols, in particular dimethicone copolyol benzoates, and process for preparing same. The benzoate esters are useful for personal care cleansing products, such as bar and liquid soaps, skin and hair care products and textiles and fibers. The compounds are prepared by reacting benzoic acid with hydroxyl terminated polyether polysiloxane copolyols.
Claims63
A benzoate ester of hydroxyl terminated polyether polysiloxane copolyol having the following structure:
- wherein x and y are integers which independently range from 1 to 50;
- R1, R2, R3 and R4 may all be the same or different, provided that at least one of R1, R2, R3 or R4 is a hydroxyl terminated polyether group;
- provided that when one of R1, R2, R3 and R4 is a hydroxyl terminated polyether, the others of R1, R2, R3 and R4 are selected from the group consisting of alkyl, aryl, alkaryl, aralkyl, alkoxy, substituted alkyl, substituted aryl, and mixtures thereof;
- and wherein the hydroxyl terminated polyether group has been esterified with Benzoic Acid and has the structure
- wherein R5 is an alkyl group of one to ten carbon atoms;
- p is a number from one to ten;
- R6 is an alkyl group of from two to twelve carbon atoms;
- m is a number from one to fifty;
- R7 is an alkyl group of from two to twenty carbon atoms;
- and n is a number from one to fifty.
