Abstract
The present application relates to citric acid-modified polypropylene glycols which are represented by Formula (1) or, as well as compositions comprising such compounds. The polypropylene glycol-based compounds of the invention are useful as additives and in particular as emulsifying agents in e.g. cooling lubricants, as release agents, as well as additives for cosmetic products.
Claims19
A compound according to Formula (1)
- wherein each A is independently represented by [CH2CHCH3O] or [CHCH3CH2O];
- R1 and R2 each independently are hydrogen, a linear or branched C6-34 alkyl group which is optionally substituted with OH, a linear or branched C6-34 alkenyl group which is optionally substituted with OH, or a group of the formula N(R3)—C(═O)—R4;
- L is a direct bond, C(═O), C1-10 alkylene or a polypropylene oxide unit of the formula [A]n+2;
- R3 is H, C1-6 alkylene or O—C1-6 alkylene;
- R4 is a linear or branched C6-34 alkyl group which is optionally substituted with OH, or a linear or branched C6-34 alkenyl group which is optionally substituted with OH;
- n is an integer from 0-50;
- m is 0 or 1, l is 0 or 1, with the proviso that at least one of m and l is 1;
- x is 0 or 1, y is 0 or 1 and the sum of x and y is 1 and
- v is 0 or 1, w is 0 or 1 and the sum of v and w is 1.
