Abstract

The emulsifier composition may be formulated as YA ¹ .OC. (HR) CC (HR ¹ ) .CO.A. (C _m H _2m O) _n .R ^{2 of} formula (I) or formula (II) YA ¹ .OC. (HR) CC (HR ¹ ) .CO.A. (C _m H _2m O) _n .C _p H _2p .A.CO (HR ¹ ) CC (HR) CO.A ¹ .Y. Surfactants are effective in emulsifying substances, such as agrochemicals, to provide a stable emulsion, as well as surfactants big-dicarboxylic acid polyalkyleneoxy half ester derivatives of The emulsifiers may be formed as concentrates which may comprise particularly effective chemical agents and typically organic liquids or solvents, such that the concentrates form an emulsion directly upon dilution with water.
