Abstract

Improved process for making carboxyalkylated alkyl polyether surfactants with narrow polyethoxy chain distributions using approximately equimolar ratios of alcohol and alkali metal or alkali metal hydride catalyst. The products are useful in making improved carboxyalkylated alkyl polyether surfactants having specific narrow ranges of ethoxylation and containing less than about 6% fatty alcohol. Detergent compositions containing said alkyl carboxyalkylated polyether surfactants and having less than about 6% fatty alcohol by weight of said alkyl carboxyalkylated polyether surfactants. Processes of making said alkyl carboxyalkylated polyether surfactants.
