What it is

A semi-synthetic surfactant created by reacting coconut oil fatty acids with hydrolyzed oat protein. The result is a mild cleansing molecule that is less irritating than traditional sulfates.

How it works

It works by reducing the surface tension of water, allowing oils and dirt to be lifted away from the skin and rinsed off. The oat protein portion also deposits a thin, conditioning film on the skin, which helps retain moisture and reduce irritation.

Pros

Ultra-gentle on skin

Unlike sodium lauryl sulfate, this ingredient cleanses without disrupting the skin barrier, making it ideal for eczema-prone or reactive skin.

Adds conditioning benefits

The oat protein component deposits a moisturizing film, so skin feels soft and hydrated after washing, not tight or dry.

Cons and cautions

Lower foam volume

It produces a creamy, low-lather experience that some users accustomed to bubbly cleansers may find less satisfying.

Higher cost

As a specialty ingredient, products containing it tend to be priced higher than conventional sulfate-based cleansers.

Best for

  • People with dry or sensitive skin looking for a non-stripping cleanser
  • Anyone seeking a sulfate-free, gentle cleansing option

Use caution if

  • Those who prefer a rich, foamy lather may find it less satisfying

Usage tips

Use in a gentle, sulfate-free cleanser for daily face washing.
Pair with hydrating ingredients like glycerin or aloe for extra moisture retention.
Avoid using with high-pH ingredients that could reduce its mildness.
