Ingredient review
Sodium Cocoyl Hydrolyzed Collagen
INCI: SODIUM COCOYL HYDROLYZED COLLAGEN
A gentle, coconut-derived cleanser that also conditions skin and hair, making it a good choice for sensitive or dry types.
In plain English
Sodium Cocoyl Hydrolyzed Collagen is a mild cleansing ingredient made by combining fatty acids from coconut oil with broken-down collagen proteins. It helps remove dirt and oil without stripping the skin's natural moisture barrier, and it leaves skin and hair feeling soft and smooth rather than tight or dry.

Quick decision guide
Useful, but context matters
Sodium Cocoyl Hydrolyzed Collagen is generally a lower-concern ingredient when the full formula suits your skin.
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 Collagen.
- 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 oil fatty acids with hydrolyzed collagen (collagen broken into smaller peptides). It appears as a clear to slightly hazy liquid in formulas.
How it works
It works by lowering the surface tension between water and oil, allowing dirt and excess sebum to be rinsed away. The collagen-derived portion deposits a thin, moisturizing film on skin or hair, reducing friction and improving softness.
Pros
Gentle on skin
Its mild cleansing action helps maintain the skin's moisture barrier, reducing the risk of irritation or dryness compared to harsher surfactants.
Dual cleansing and conditioning
It not only cleans but also deposits collagen peptides that leave skin and hair feeling softer and smoother after rinsing.
Cons and cautions
Lower foam volume
It produces a creamier, less bubbly lather than sodium lauryl sulfate, which some users may perceive as less effective even though it cleans just as well.
Potential allergen for some
Because it is derived from coconut oil, people with coconut allergies should patch test or avoid products containing this ingredient.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Anyone wanting a sulfate-free, mild shampoo or body wash
Use caution if
- Individuals with a known allergy to coconut or coconut-derived ingredients
Usage tips
Safety summary
Sodium Cocoyl Hydrolyzed Collagen is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for sensitive skin. As with any ingredient, patch testing is recommended for those with known coconut allergies.
Research notes
Research on this specific ingredient is limited, but studies on similar amino acid-based surfactants show they are mild, non-irritating, and effective cleansers. The collagen component provides surface conditioning without significant penetration.
Common label clues
- Typical concentration
- 1% to 10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets; generally recognized as safe when used as directed
- Common uses
- Facial cleansers, Body washes, Shampoos, Conditioners, Bar soaps
- Environmental note
- Derived from renewable coconut oil and collagen byproducts; biodegradable and considered more eco-friendly than some petroleum-based surfactants
Good to know
- Hydrolyzed collagen in this ingredient is too large to penetrate deeply into skin, so it works mainly on the surface as a conditioner
- It is often listed near the middle or end of ingredient lists because it is used at moderate concentrations
