Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

What it is
TEA-Cocoyl Sarcosinate is a surfactant derived from coconut fatty acids and sarcosine, an amino acid naturally found in the body. It is often used as a gentler alternative to sodium lauryl sulfate (SLS) in cleansers.
How it works
It works by reducing the surface tension between water and oil, allowing dirt and sebum to be rinsed away. Its mildness comes from its large molecular structure, which is less penetrating and less disruptive to the skin's lipid barrier compared to harsher surfactants.
Pros
Extremely mild on skin
Its amino-acid base makes it one of the gentlest surfactants, ideal for daily use without causing irritation or tightness.
Supports moisture retention
Unlike sulfates, it cleans without stripping natural oils, helping your skin stay hydrated and comfortable after washing.
Cons and cautions
Lower foaming power
It produces a creamy, low foam rather than big bubbles, which some users may find less satisfying.
Less effective on heavy makeup
If you wear long-wear or waterproof makeup, you may need a double cleanse or a stronger first cleanser.
Best for
- People with sensitive or reactive skin
- Those with dry or dehydrated skin looking for a non-stripping cleanser
Use caution if
- Individuals seeking a high-foaming, deep-cleansing experience for very oily skin
