Abstract:
Surfactant concentrates containing the following components: I) at least one base-catalyzed reaction product of reactants comprising: A) at least one compound of formula I wherein each X group is a halogen atom or one X group is a halogen atom and two X groups represent an epoxy oxygen atom, which is attached to two adjacent carbon atoms in the Rgroup to form an epoxy group, and Ris an alkanetriyl group containing from 3 to 10 carbon atoms; and B) at least one compound having the formula II wherein Ris a substituted or unsubstituted, saturated or unsaturated, organic group having from 1 to 36 carbon atoms; X is —O—, —S—, or —NR— where Ris hydrogen or a C-Calkyl group; each AO group is independently an ethyleneoxy, 1,2-propyleneoxy, or 1,2-butyleneoxy group, n is a number of from 0 to 200, preferably from 1 to 100, more preferably from 2 to 20; and Y is hydrogen, or Y can be a mercapto group or an amino group (amino or C-Calkylamino group) in place of the terminal —OH group, provided that when Y is mercapto, amino, or a C-Calkylamino group, n is at least 1; and II) at least one nonionic surfactant other than nonionic surfactants of component I).
