Non-ionic surface active compsns. contain a hydroxy-fatty acid amide- polyoxyalkylene ether having formula (H2NOCR-O(CHR'CH2O)yH)z(I) (where R is 7-21C hydrocarbyl, R' is H or lower alkyl, y is integer 1 to 100 and z is integer >=1). Compsns. are useful as dispersants, corrosion-inhibitors, anti-microbial agents and preservatives, wetting agents and emulsifiers, and stabilisers, e.g. for I in water. (I) are suitable for use in food, cosmetics and pharmaceutical industry. |
