ABSTRACT:
Tensio-active cyclic polyethers of the general formula: ##STR1## where A refers to a hydrophile block chosen from the amine, ammonium, ammonio alkyl carboxylate, ammonio alkyl sulfonate, amide, sulfonamide, ether, thioether, hydroxyl, ester and acid groupings.
These polyethers may be prepared (1) by reaction of alcohol or of undecylenic acid with thioacetic acid, (2) saponification with an alkaline base, (3) reaction of the product obtained in (2) with the tetramer of epichlorohydrin or of epibromohydrin, (4) reaction of mesylate or tosylate of the compound obtained in (3) either (a) with dimethylamine or methylethanolamine, the resulting compound being able to be salified or alkylated, or (b) with the mercapto ethanol or mercapto glycerol; the compounds thereby obtained being then able to be submitted to reactions of polyaddition of ethylene oxide and/or of glycidol oxide.
These tensio-active cyclic polyethers are suitable for use in the cosmetic, textile, insecticide and similar industries.
