An amide surfactant compound of formula 1: R1-CO-NR2R3 (1) wherein R1 is a polymeric hydrophobic group; R2 is a CH2- (CHOR4) n-CH2OR4 group in which nes of 4 to 6 and R4 is hydrogen, C1-6 alkyl or a saccharide residue, containing at least 2g free hydroxyl groups; and R3 is hydrogen, C1-22 hydrocarbyl, substituted alkyl, or R3 is independently as defined above for R2. Such compounds are useful as emulsifiers and / or stabilizers for water emulsions in oil or as dispersants for solids in aqueous or non-aqueous liquids. Particular end-use applications include the use of such compounds as emulsifiers. Stabilizers or dispersants in the preparation of polyacrylamide, particularly in the treatment of water; in emulsion polymerization in reverse phase; in explosives in emulsion; in personal hygiene compositions that include an aqueous phase dispersed or emulsified in an oil phase; in emulsions or agrochemical dispersions; in reverse phase drilling fluids; in emulsions and oil concentrates for lamination; and in emulsions and fluid concentrates for cutting operations. |
