Chemistry: They derive from the carboxymethylation of fatty alcohol ethoxylates with sodium monochloroacetate. The Alkylethers Carboxylates developed by our team have a “soap-like” structure with a polyoxyethylene chain, inserted between the fatty chain and the carboxylic group, that greatly improves the solubility in hard water.
Applications: Our derivatives with alkyl chains longer than C16 and with low ethoxylation degrees are w/o emulsifiers very stable also in extreme temperature and pH conditions (metalworking and oil & gas sectors).
Chemistry: They derived from the esterification of fatty alcohol ethoxylates and one or two carboxylic group of citric acid. They can be sold both in acid or salified forms.
Applications: They are milder surfactants to the skin and mucous membranes in comparison to conventional anionic surfactants and are able to reduce the irritating power of laurylsulfates and laurylethersulfates.
Owing to these properties, the alkylether citrates are particularly well suited as co-surfactants in the personal care formulations
