Amide surfactant compound of the formula (I): R?1-CO-NR2R3¿, where R1 is a polymeric hydrophobe group; R2 is a group CH¿2?-(CHOR?4)¿n-CH2OR4 where n is from 3 to 6 and R4 is hydrogen, C¿1? to C6 alkyl or a saccharide residue, containing at least 2 free hydroxyl groups; and R?3¿ is hydrogen, C¿1? to C22 hydrocarbyl, substituted alkyl, or R?3¿ is independently as defined above for R2, are useful as emulsifiers and/or stabilisers for water in oil emulsions, or as dispersants for solids in aqueous or non-aqueous liquids. Particular end use applications include as emulsifiers, stabilisers or dispersants in making polyacrylamide, particularly for water treatment, by inverse emulsion polymerisation; emulsion explosives; personal care compositions including an aqueous phase dispersed or emulsified in an oil phase; agrochemical emulsions and concentrates, and cutting fluid emulsions and concentrates. |
