What Is Cocoyl Hydrolyzed Oat Protein?
Cocoyl Hydrolyzed Oat Protein is a plant-based ingredient created by joining fatty acids from coconut with small protein fragments from oats. The result is a gentle surfactant that combines the softness of oats with the cleansing power of coconut. It first appeared in natural and sulfate-free shampoos in the early 2000s when brands began looking for milder alternatives to harsh detergents. Today formulators prize it for its ability to clean while leaving skin and hair comfortable.
The production process starts with oat proteins that are broken down into smaller peptides through controlled hydrolysis. Separately coconut fatty acid chloride is prepared from coconut oil. When the two meet in a condensation reaction they form Cocoyl Hydrolyzed Oat Protein, which is then neutralized and purified into a clear to pale yellow liquid.
You will commonly spot this ingredient in sulfate-free shampoos, co-washes, micellar facial cleansers, foaming body washes, baby products, conditioning masks and lightweight leave-in sprays. Its mild nature makes it popular in products aimed at sensitive skin and color-treated hair.

Comedogenic Rating
Rating: 1 / 5
Cocoyl Hydrolyzed Oat Protein scores a 1 because its large oat-derived peptides and water-soluble coconut fatty acids rinse away easily and do not linger inside pores. It lacks the heavy oils or waxes that typically lead to clogged pores so the risk of breakouts is very low.
Suitable for acne-prone skin in both face and body products.
Most formulas that use this ingredient are wash-off cleansers, which further lowers any pore-clogging chance
Summary
Cocoyl Hydrolyzed Oat Protein is a mild multitasker that cleans, softens hair and conditions skin all in one. The coconut portion lifts dirt while the oat peptides coat strands and skin with a light, silky layer that locks in moisture.
It has become a go-to choice for brands making sulfate-free shampoos, gentle body washes and baby products, though it is still less common than classic surfactants like sodium laureth sulfate.
Current research shows a strong safety profile with only rare reports of irritation. As with any new cosmetic ingredient it is wise to do a quick patch test before full use, just to make sure your skin agrees with it
