The surface activities of amino acid ester hydrochlorides were determined. Among these esters, amino acid lauryl ester hydrochlorides showed the best performance, with respect to lowering power of surface tension, foaming power and wetting power. The lowering power of surface tension decreased with increasing the carbon number of the amino acid residue, that is, in the following order, glycine, alanine and valine. On the contrary the wetting power gradually increased. The cmc values of L-forms were smaller than those of DL-forms. But there were no notable differences in the solubility, lowering power of surface tension, foaming power and wetting power.
