Abstract
Abstract An emulsifying or solubilizing agent composition comprising 58 to 95% by weight of a polyoxyethylene (10 to 100) sorbitol branched saturated fatty acid (C 11 to C 21 ) ester having from 3 to 6 ester groups in the molecule, 0.5 to 2.5% by weight of an alkali metal salt of a linear or branched fatty acid (C 11 to C 21 ), 2.5 to 6.0% by weight of a linear or branched fatty acid (C 11 to C 23 ) and 2 to 35% by weight of a branched saturated fatty acid ester of polyethylene glycol having an average molecular weight of from 150 to 2000.
