Common Name(s): Amino acid or organic acid salt surfactant,mild anionic surfactant,gentle cleansing

CAS Number: N/a

DESCRIPTION

What It Does: Provides gentle, effective cleansing with minimal skin irritation — suitable for sensitive skin, baby care, and facial cleansers requiring mild surfactant systems.

Why It's Used: Amino acid and organic acid surfactants provide the gentlest anionic cleansing — glutamate, taurate, and sarcosinate head groups have inherently lower skin protein denaturing activity than sulfate head groups from the amino acid's protein-complementarity chemistry.

How It Works: The amino acid-derived head group (glutamate, glycinate, taurate, sarcosinate) provides anionic character at cleansing ph while the amino acid backbone has structural complementarity with skin proteins — reducing the electrostatic protein-surfactant binding energy that causes irritation compared to simple sulfate anionics.

Typically Found In: Gentle cleansers,baby care,facial wash

SCIENTIFIC NOTE

Amino acid surfactant mildness ranking: cocoyl glutamate ≈ cocoyl glycinate > cocoyl sarcosinate > lauryl glucoside > sles > sls — the amino acid head group provides consistently lower zein protein solubilisation (irritation predictor) than equivalent-chain-length sulfates.
