What it is
A semi-synthetic surfactant created by reacting coconut fatty acids with hydrolyzed (broken down) oat protein. It cleanses while depositing a thin layer of protein on skin or hair for conditioning.
How it works
The coconut fatty acid part acts as a mild detergent, lifting away dirt and oil. The oat protein portion helps bind moisture and forms a protective film that reduces irritation and leaves skin feeling smooth.
Pros
Extra gentle on skin
Unlike harsher sulfates, cocoyl hydrolyzed oat protein cleanses without stripping natural oils, reducing the risk of dryness and irritation.
Adds a touch of conditioning
The oat protein leaves a subtle film that helps skin and hair feel softer and more hydrated after washing.
Cons and cautions
Milder lather
It produces a creamier, less bubbly foam than traditional cleansers, which some users may find less satisfying.
Higher cost potential
As a specialty ingredient, products containing it may be priced higher than basic drugstore cleansers.
Best for
- People with dry, sensitive, or eczema-prone skin
- Those looking for a sulfate-free, gentle cleanser
Use caution if
- Individuals who prefer high-foam, deep-cleansing formulas
