Abstract

Polyalkene alcohol polyalkoxylates R—(CH2)n—(O—A)m—OH, where R is a polyalkene radical derived from C2- to C30-alkenes and having a number average molecular weight from 300 to 5000, A is an alkylene group of 2 to 8 carbon atoms, m is a number up to 200, with the proviso that the oxygen in the oxyalkylate radical accounts for at least 16.5% by weight of the number average molecular weight of the total molecule I, and n is 0 or 1, are suitable as carrier oils in fuel and lubricant compositions.
