1. A composition comprising an amine alkoxylate of formula I:wherein R1-R7 and R1′-R7′ are independently hydrogen or hydrocarbyl groups; x and x′ are independently 0 (a covalent bond) or an integer in the range of 1-10, and if x or x′ is greater than 1, then R1 and R1′ are the same or different; and A, A′ and A″ are independently alkoxylate homopolymer or copolymer chains where the alkyl of the alkoxylate units is independently selected from CH2CH2, CH2CH(CH3), CH(CH3)CH2, CH2CH(CH2CH3), or CH(CH2CH3)CH2 groups.
