TENSOTIVE COMPOUND, METHODS OF PRODUCTION OF A COMPOUND, POLYMERIZATION IN EMULSION, INHIBITION OF GAS HYDRAT FORMING, POLYMERIZATION OR COPOLYMERIZATION OF EMULSIN WATER PRODUCTS , DISPERSION OF A SOLID IN A WATER, DETERGENT FORMULATION FOR WASHING CLOTHES, AGRICULTURAL FORMULATION, DRILLING FLUID, DISPERSION OF A SOLID IN A NON-WATER, FLUID, EMULSION, FLUID, EMULSION, FLUID FOR METAL WORKING. oligoester fatty esters of a dicarboxylic acid and a polyol retaining at least one hydroxyl group, in particular of formula (1): R¹- ¢ OR²O-C (O) -R³- (O) C-! mR¬ 4¬ ( I) wherein R¹ is H, a monocarboxylic acid group, or R¬ 6¬O- ¢ C (O) -R³- (O) C! -R² are polyol residues having at least one substituent-free hydroxyl; R³ is hydrocarbylene; R¬ 4¬ is -OH, -OM, where M is a salt, amine or ammonium forming metal, -0R¬ 6¬ or -OR²O-R¬ 7¬; R¬5¬ is Cila7 a to C ~21 ~ hydrocarbyl; R6 is hydrocarbyl C8 to C22; R¬7¬ is H, or -C (O) R¬5¬; and m is from 1 to 20; provided that at least one of R 'and R¬ 4¬ is or includes a group C ~ 8 ~ to C ~ 22 ~, they are surfactants. A range of surfactant properties can be obtained by varying the molecules within these ranges. In particular, where R² is derived from a higher polyol, for example sorbitol, R³ is C ~ 2 ~ C ~ 6 ~ and the fatty terminal group is C ~ 8 ~ C ~ 14 ~, the products may be highly soluble. in water and effective oil-in-water emulsifiers.
