Sodium Cocoyl Hydrolyzed Rice Protein
INCI: SODIUM COCOYL HYDROLYZED RICE PROTEIN
A mild, plant-based cleanser that removes dirt without stripping the skin, making it ideal for sensitive or dry skin types.
In plain English
Sodium Cocoyl Hydrolyzed Rice Protein is a gentle cleansing ingredient made by combining coconut oil fatty acids with broken-down rice proteins. It helps wash away dirt and oil without stripping your skin's natural moisture barrier. Because it's derived from natural sources and is very mild, it's often used in products for sensitive skin, baby care, or dry skin. It also leaves skin feeling soft and smooth, not tight or dry.

Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Sodium Cocoyl Hydrolyzed Rice Protein.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
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 coconut oil fatty acids with hydrolyzed (broken down) rice protein. The result is a mild, biodegradable cleansing agent that is gentle on skin and hair.
How it works
It works by reducing the surface tension of water, allowing oil and dirt to be lifted away from the skin and rinsed off. Unlike harsher sulfates, it does not disrupt the skin's lipid barrier, so it cleanses without causing dryness or irritation. The rice protein component also leaves a light conditioning film on skin and hair, improving feel and manageability.
Pros
Very gentle on skin
Its mild cleansing action makes it suitable for daily use, even on sensitive or compromised skin, without causing tightness or irritation.
Conditioning effect
Unlike many cleansers that leave skin dry, this ingredient deposits a light protein film that helps maintain softness and smoothness after washing.
Cons and cautions
Lower foaming
It produces a creamy, low foam rather than big bubbles, which some users may associate with less effective cleansing.
Limited heavy-duty cleansing
On its own, it may struggle to remove heavy makeup or waterproof sunscreen, often requiring a double-cleansing approach.
Best for
- People with sensitive or easily irritated skin
- Those with dry or dehydrated skin looking for a non-stripping cleanser
- Anyone seeking a more natural or gentle alternative to traditional sulfates
Use caution if
- Individuals with a known allergy to rice or coconut-derived ingredients (rare)
