Cocoyl Hydrolyzed Rice Protein
INCI: Cocoyl Hydrolyzed Rice Protein
A mild, amino-acid-based cleanser that cleans without stripping and leaves hair and skin feeling soft.
In plain English
Cocoyl Hydrolyzed Rice Protein is a gentle cleansing ingredient made by combining coconut oil fatty acids with broken-down rice proteins. It helps remove dirt and oil without stripping your skin or hair of their natural moisture. Because it's derived from rice protein, it also leaves a light, conditioning film that can make hair feel smoother and skin feel softer after washing.

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 and conditioning agent created by reacting coconut fatty acids with hydrolyzed (broken-down) rice protein. It belongs to the family of amino-acid-based cleansers, known for their mildness.
How it works
In a cleanser, it surrounds and lifts away dirt, oil, and makeup so they can be rinsed off with water. Unlike harsher sulfates, its large molecular structure is less likely to penetrate the skin barrier, reducing irritation. The rice protein portion also deposits a thin, moisturizing film on hair and skin, helping to reduce frizz and improve softness.
Pros
Very gentle on skin
Its large molecular structure means it's less likely to irritate or disrupt the skin barrier, making it a great choice for sensitive or eczema-prone skin.
Adds softness and manageability
The rice protein component leaves a light conditioning film on hair and skin, helping to reduce static, frizz, and dryness after washing.
Cons and cautions
Lower foam volume
It produces a creamy, low lather rather than big, bubbly foam. Some users may feel it isn't cleaning as thoroughly, even though it is.
May need help with heavy makeup
On its own, it may not fully remove waterproof makeup or long-wear sunscreen. A double-cleansing routine or a stronger primary surfactant may be needed.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Anyone wanting a sulfate-free shampoo that still cleans effectively
Use caution if
- Those who prefer a very high-foam, bubbly cleanser
- Individuals with a known allergy to rice or coconut-derived ingredients (rare)
