What Is Sodium Lauroamphoacetate?
As an amphoteric surfactant, this ingredient is commonly used in facial cleansers, body washes, shampoos, and baby care products. Amphoteric surfactants are able to adapt to different pH levels, which helps improve mildness and skin compatibility.
Compared to harsher cleansing agents, this type of surfactant cleanses effectively while remaining gentle on the skin.
Where Does It Come From?
The ingredient is typically derived from fatty acids sourced from coconut oil or palm kernel oil. These fatty acids are processed into a surfactant designed to balance cleansing performance with reduced irritation.
Its amphoteric structure contributes to versatility and mildness in gentle and low-irritation formulations.
Why Is It Used in Skincare?
Formulators often select this surfactant for its ability to cleanse while maintaining skin comfort. It is commonly used because it offers:
-
Low irritation potential
-
Soft, creamy foam
-
Good compatibility with sensitive and baby skin formulas
-
Ability to reduce the harshness of other surfactants
As a result, it is frequently included in sulfate-free and mild cleansing products.
Is It Gentle on Skin?
In most cases, yes. Sodium Lauroamphoacetate is generally considered mild and well tolerated, particularly when used in balanced formulations. It is commonly found in products designed for sensitive skin, dry skin, and scalp care.
It is also often paired with other mild surfactants for sensitive skin to further improve skin tolerance.
Who Should Be Cautious?
Although considered gentle, individual skin responses can vary. People with highly sensitive or reactive skin should patch-test new products before regular use.
As with most cleansers, irritation is more likely to be caused by added fragrances, essential oils, or preservatives rather than the surfactant itself.
