DISPERSANT FORMULATION FOR CLEANING UP OIL SPILLS

摘要

A dispersant formulation and process for dispersing oil spills on water, which formulation contains: (a) a sorbitan monoester of a C10-C20 aliphatic monocarboxylic acid, (b) a polyoxyethylene adduct of a sorbitan monoester of a C10-C20 aliphatic monocarboxylic acid which has from 6 to 30 ethyleneoxide units per mole of ester, (c) an alkali metal salt of a dialkyl sulfosuccinate wherein the alkyl group is a branched chain radical containing 4 to 13 carbon atoms, (d) a polyoxyethylene adduct of a sorbitan triester of a C10-C20 aliphatic monocarboxylic acid having from 6 to 30 ethyleneoxide units per mole of triester or a polyoxyethylene adduct of a sorbitol hexaester of a C10-C20 aliphatic monocarboxylic acid having from 6 to 30 ethyleneoxide units per mole of hexaester, and (e) a solvent comprising at least one of a propylene glycol ether, ethylene glycol ether, water, alcohol, glycol and a paraffinic hydrocarbon.
