Potassium Behenoyl Hydrolyzed Rice Protein
INCI: Potassium Behenoyl Hydrolyzed Rice Protein
A mild, amino-acid-based cleanser derived from rice protein that effectively cleanses without stripping the skin barrier.
In plain English
This ingredient is a gentle cleanser made by combining rice protein with a fatty acid from rapeseed oil. It works like a soap but is much kinder to your skin because it cleans without removing too many of your skin's natural oils. You'll often find it in creamy cleansers and shampoos that claim to be mild or moisturizing.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic surfactant created by reacting behenic acid (a fatty acid from rapeseed oil) with hydrolyzed rice protein. The result is a mild cleansing molecule that is part of the amino-acid surfactant family.
How it works
It has a water-loving head and an oil-loving tail. When you wash, the tails grab dirt and oil while the heads rinse away with water. Because the rice protein part is large and gentle, it doesn't penetrate the skin deeply, reducing irritation risk.
Pros
Very gentle on skin
Its large molecular structure means it stays on the surface and doesn't penetrate, reducing the chance of irritation or dryness.
Conditioning feel
The rice protein component leaves a subtle film on skin and hair that feels soft and smooth, unlike harsher cleansers that can leave a tight, dry feeling.
Cons and cautions
Lower foam volume
It produces a creamy, low foam rather than big bubbles, which some users associate with less cleansing power even though it cleans effectively.
Higher cost
As a specialty amino-acid surfactant, it is more expensive to produce, which can increase the price of the final product.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Anyone wanting to avoid harsh sulfates like SLS/SLES
Use caution if
- Those who prefer a very high-foam, bubbly cleanser may find it too mild
Usage tips
