What it is
A semi-synthetic surfactant created by reacting olive oil fatty acids with hydrolyzed oat protein. The result is a mild cleansing molecule that is less irritating than traditional sulfates.
How it works
The olive oil portion attracts and lifts dirt and oil from the skin, while the oat protein part helps the ingredient rinse away cleanly. It also deposits a thin, conditioning film on the skin that reduces water loss and leaves skin feeling soft.
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 moisture while cleansing
The oat protein component helps retain hydration, so your face doesn't feel tight or dry after washing.
Cons and cautions
Low foam production
If you enjoy a bubbly, foamy wash, this ingredient may feel less satisfying because it produces a creamy, low-lather texture.
Higher cost
Products formulated with this ingredient tend to be pricier than conventional sulfate-based cleansers due to the more complex manufacturing process.
Best for
- People with dry or sensitive skin looking for a non-stripping cleanser
- Anyone wanting to avoid harsh sulfates in their skincare routine
Use caution if
- Those who prefer a rich, foamy lather may find this too low-foaming
