    Abstract: The invention relates to cleavable surfactants of formula: in which R′ and R, which may be identical or different, represent a hydrogen atom or a linear or branched, saturated or unsaturated alkyl radical, the sum of the carbon atoms of R′ and R being between 5 and 42. The invention also relates to the corresponding derivatives obtained by alkaline hydrolysis or amidation. The invention furthermore relates to the preparation of these surfactants from glucono-1(5)-lactone and a compound of formula R—CO—R′ in the presence of an acid catalyst, R and R′ having the meaning given above. The surfactants are used in particular in emulsion polymerization and in the field of cosmetics.
