Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A mild anionic surfactant created by combining caprylic acid (from coconut oil) with glutamic acid (an amino acid). It is often used in sulfate-free cleansers.
How it works
It reduces the surface tension between water and oil, allowing impurities and excess sebum to be emulsified and washed away. Its large molecular structure makes it less penetrating and less irritating than smaller surfactants like sodium lauryl sulfate.
Pros
Very gentle on skin
Its large molecular structure means it doesn't penetrate deeply, reducing the risk of irritation and making it suitable for sensitive skin.
Maintains moisture balance
Unlike harsh detergents, it cleans without stripping natural oils, helping to keep the skin barrier intact and hydrated.
Cons and cautions
Lower foam volume
It produces a creamy, low-foam lather that some users may find less satisfying than the rich foam of sulfate cleansers.
Higher cost
As a specialty amino-acid surfactant, it is more expensive to produce than conventional sulfates, which can raise product prices.
Best for
- People with sensitive or reactive skin
- Those with dry or dehydrated skin
- Anyone seeking a sulfate-free cleanser
Use caution if
- Individuals with a known allergy to coconut-derived ingredients (rare)
