Sodium Cocoyl/Olivoyl Hydrolyzed Oat Protein
INCI: SODIUM COCOYL/OLIVOYL HYDROLYZED OAT PROTEIN
A mild, multi-tasking surfactant that cleanses without stripping and leaves skin feeling soft, ideal for sensitive or dry skin.
In plain English
This ingredient is a gentle cleanser made by attaching coconut and olive fatty acids to oat protein. It helps remove dirt and oil without stripping your skin's natural moisture barrier, and the oat protein leaves a light, conditioning film that helps skin feel soft and smooth. It's often used in sulfate-free cleansers and is well-tolerated by most skin types.

Quick decision guide
Easy yes for most routines

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/Olivoyl Hydrolyzed Oat 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 and conditioning agent created by reacting coconut and olive fatty acids with hydrolyzed oat protein. The result is a mild, amino acid-based cleansing molecule that is biodegradable and derived from renewable plant sources.
How it works
The fatty acid tails (from coconut and olive) attract and trap oil-based dirt, while the oat protein head group is water-soluble, allowing the whole complex to be rinsed away. The oat protein portion also deposits a thin, moisturizing film on skin and hair, reducing the tight, dry feeling often left by harsher cleansers.
Pros
Ultra-gentle cleansing
Cleanses effectively without disrupting the skin's moisture barrier, making it ideal for daily use on sensitive or compromised skin.
Built-in conditioning
The oat protein component deposits a light film that helps maintain softness and reduces post-wash tightness, unlike many harsher surfactants.
Cons and cautions
Low foam profile
Produces a creamy, low-lather experience that may feel less satisfying to those accustomed to bubbly cleansers.
Higher cost
As a specialty, plant-derived ingredient, it is more expensive than commodity surfactants like sodium lauryl sulfate, which can raise product prices.
Best for
- People with dry, sensitive, or eczema-prone skin
- Anyone seeking a sulfate-free, gentle cleanser
Use caution if
- Those who prefer high-foaming, bubbly cleansers (may find this too low-lather)
Usage tips
Safety summary
Considered very safe for topical use. Low irritation and sensitization potential. No known toxicity concerns at typical cosmetic concentrations.
Research notes
Amino acid-based surfactants like this one are well-documented for their mildness and skin compatibility. Oat protein has additional soothing and moisturizing properties supported by traditional use and some clinical studies.
Common label clues
- Typical concentration
- 1–10% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU; no specific restrictions.
- Common uses
- Facial cleansers, Body washes, Shampoos, Conditioners, Micellar waters
- Environmental note
- Derived from renewable plant sources (coconut, olive, oat) and is biodegradable, making it a more eco-friendly surfactant choice.
Good to know
- This ingredient is often found in 'amino acid' or 'milk protein' cleansers.
- It is compatible with other mild surfactants to adjust foam and feel.
- The oat protein portion can help soothe minor irritation.
