SCIENTIFIC NOTE
N-acyl alaninate mildness rationale: amino acid-derived anionic surfactants have the same polar backbone as skin proteins โ the amino acid head group interacts with skin proteins through structurally complementary hydrogen bonding (protein-to-protein compatible geometry) rather than the disruptive electrostatic denaturing of conventional sulfate surfactants. structural complementarity with skin proteins provides the documented superior mildness of amino acid surfactants.
