ANIONIC SURFACTANTS AND COMPOSITIONS CONTAINING THE SAME

摘要

The invention provides surfactants excellent in the balance among detergency against oily stains, rinsability, handleability and handling safety. Namely, secondary alkyl ether sulfate salt type anionic surfactants of the general formula (1) having average chain lengths of polyalkylene ether of 1.5 to 2.5; and compositions containing the surfactants: wherein R1 and R2 are each independently straight-chain or branched alkyl having 1 to 18 carbon atoms, with the total number of carbon atoms of both being 7 to 29; A is alkylene having two or more carbon atoms; n is the number of oxyalkylene repeating units and the average of n's is 1.5 to 2.5; M is alkali metal, alkaline earth metal, ammonium, or substituted ammonium; and m is the valence of M.
