ABSTRACT:
Novel ether carboxylates of the following formula (I) ##STR1## in which R represents a linear or branched alkyl or alkenyl group having from 4 to 32 carbon atoms, and A and B independently represent hydrogen or a --CH.sub.2 COOM group wherein M represents hydrogen, alkali metal, ammonium, alkanolammonium or lower alkylammonium, provided that A and B are not hydrogen at the same time are prepared by a simple reaction in which a monohaloacetic acid or a salt thereof is reacted with a mono and/or dialcoholate of an alkyl glyceryl ether of the general formula (II) ##STR2## in which R has the same meaning as defined above. Optionally, the resulting product may be converted into a free acid or a salt thereof.
Highly pure ether carboxylates can be produced from inexpensive and readily available starting materials with high yield. The carboxylates are useful as a surfactant of low stimulus and have wide utility in the fields of cosmetics, detergents, medicines, paints and so on.
