📚 Research & Evidence

🔬 The Science

Sodium cocoamphoacetate is classified as an amphoteric surfactant, meaning its molecular structure allows it to carry both positive and negative electrical charges. This dual nature influences how it works in cleansing products. According to Contact Dermatitis (2006), this ingredient has relatively weak irritant properties compared to other surfactants, which explains why manufacturers frequently include it in formulations designed for sensitive skin—including products for intimate hygiene and baby care. However, the same source documents a case where someone with atopic skin (a condition involving heightened skin reactivity) and multiple existing contact sensitivities experienced an allergic reaction to a cleanser containing sodium cocoamphoacetate.

This case report suggests that while the ingredient is gentler than many alternatives, it can still trigger allergic responses in susceptible individuals, particularly those with a history of contact allergies or compromised skin barriers.
