Abstract
Surfactant compositions suitable for the emulsification of methanol or ethanol in hydrocarbon liquids, especially diesel oil, consist of a blend of (i) from 10% to 90% by weight of block or graft copolymer in which one polymeric component is the residue of an oil-soluble complex monocarboxylic acid and another polymeric component is the residue of a water-soluble polyalkylene glycol or polyalkyleneoxy polyol and (ii) from 90% by 10% by weight of the salt of an aliphatic amino compound with a long-chain aliphatic carboxylic acid.
