A surfactant composition includes a homogeneous mixture of greater than 70%, by weight, of N-acyl alaninate surfactant of formula (I) and an N-acyl amino acid surfactant of formula (II). A process for preparation of a blend of an N-acyl alaninate surfactant and an N-acyl amino acid surfactant includes combining (a) an alanine amino acid and (b) other amino acid, an anhydrous alkali salt of the other amino acid, or both, a waterless base, and a fatty alkyl ester of formula (V) to form a mixture including alanine amino acid salt of formula (III), and other amino acid salt of formula (IV). The process further includes increasing the temperature of the mixture to 180° C. or less to form a reaction mixture. The process further includes continuously removing alkyl alcohol from the reaction mixture and allowing the reaction mixture to become substantially clear to form the blend.
