Abstract
This disclosure provides a composition comprising a mixture of molecules of Formula (I): {RO—[CH(CH3)CH2O)]b[CH2—CH2O]a}mP(═O)(O−X+)n (I), wherein R is chosen from linear or branched C10-C18 alkyl or alkenyl groups; a is 0 to 50, b is 0-30, and a+b>0; X+ is potassium, triethanolamine, or H, and m and n are each equal to 1 or 2, such that when m=1 then n=2, and when m=2 then n=1. Moreover, in the mixture some of the molecules have m=1 and n=2 and some of the molecules have m=2 and n=1, wherein the mole ratio of compounds where m=1 to compounds where m=2 is of from 1:1 to 3:1.
