Sodium Cocoyl Amino Acids is a mild, amino acid-derived anionic surfactant obtained from coconut fatty acids, used to gently cleanse and create foam in facial washes and shampoos. It is valued for being less stripping and lower in irritation potential than conventional sulfate surfactants.

| Mild eye irritation or stinging | Uncommon | On accidental ocular contact, as with most cleansing surfactants |

| Allergic contact dermatitis | Very rare | Isolated sensitization reports; uncommon for amino-acid surfactants |
