Abstract:
A lubricant composition comprisinga) from 70 to 99 percent of an optionally esterified or etherified reaction product of i) an alcohol comprising up to 6 hydroxy groups and no heteroatom other than oxygen and ii) one or more alkylene oxides of 2 to 4 carbon atoms, the total number of alkylene oxide units being from 3 to 100, which reaction product comprises up to 6 hydroxy groups or is partially or fully esterified with an aliphatic saturated or unsaturated C1-20-monocarboxylic acid or an acid halide thereof or is partially or fully etherified with a C1-4 halide or sulfate; and b) from 1 to 30 percent of a compound of Formula I wherein each R1 independently is a hydrocarbon group comprising from 1 to 6 carbon atom,each R2 independently is hydrogen, methyl or ethyl, a, b and c each are 1, and m, n and o each independently are from 0 to 12, with the proviso that the sum of m, n and o is from 1 to 12, the percentages of a) and b) being based on the total weight of a) and b), and wherein the average OH-functionality of the total of the reaction product a) and the compound b) is up to 4.5.
