Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

What it is
Potassium Cocoyl Hydrolyzed Potato Protein is a surfactant created by reacting hydrolyzed (broken down) potato protein with coconut fatty acids. The result is a mild cleansing molecule that is biodegradable and derived from renewable plant sources.
How it works
In a cosmetic product, this ingredient works by attracting both water and oil. One end of the molecule grabs onto dirt and oil on your skin, while the other end rinses away with water, lifting impurities off your skin. The protein portion also helps condition the skin, leaving it feeling softer after cleansing.
Pros
Very gentle on skin
Unlike harsh sulfates, this surfactant cleanses without disrupting the skin's moisture barrier, making it ideal for daily use on sensitive or dry skin.
Conditioning effect
The potato protein component helps leave skin feeling soft and smooth after washing, reducing the need for additional moisturizers.
Cons and cautions
Lower foam volume
This ingredient produces a creamy, low foam rather than big bubbles, which may not feel as satisfying to people used to high-foam cleansers.
Higher cost
As a specialty plant-derived surfactant, it is typically more expensive than common alternatives like sodium lauryl sulfate, which can raise product prices.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Those who prefer plant-based or mild cleansing ingredients
Use caution if
- Individuals who prefer high-foaming, lathering cleansers
