Ingredient review
Cocamidopropyl Dimethylaminohydroxypropyl Hydrolyzed Collagen
INCI: COCAMIDOPROPYL DIMETHYLAMINOHYDROXYPROPYL HYDROLYZED COLLAGEN
A gentle conditioning ingredient that combines collagen's moisturizing benefits with mild cleansing properties, but its complex name can be misleading.
In plain English
This ingredient is a modified protein made by attaching a fatty acid from coconut oil to hydrolyzed collagen (broken-down animal protein). It helps hair and skin feel softer and smoother by depositing a thin film that reduces friction and locks in moisture. In shampoos, it also helps clean without stripping natural oils.

Quick decision guide
Useful, but context matters
Cocamidopropyl Dimethylaminohydroxypropyl 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 Cocamidopropyl Dimethylaminohydroxypropyl 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 compound created by chemically bonding cocamidopropyl (derived from coconut oil) with a modified form of hydrolyzed collagen (collagen broken into smaller peptides). It acts as a mild surfactant and conditioning agent.
How it works
The fatty part (cocamidopropyl) helps the ingredient bind to hair and skin surfaces, while the collagen peptides provide moisture and film-forming properties. This reduces static, improves manageability, and leaves a smooth feel without heavy buildup.
Pros
Gentle conditioning
Provides noticeable softness and manageability to hair without the heaviness of silicones.
Mild cleansing
Works as a gentle surfactant that cleans without stripping natural oils, making it suitable for daily use.
Cons and cautions
Not vegan-friendly
Contains hydrolyzed collagen sourced from animal skin or bones, so it's unsuitable for vegans or those avoiding animal products.
Potential for irritation
Though generally mild, cocamidopropyl derivatives can cause irritation or allergic reactions in a small number of sensitive individuals.
Best for
- People with dry or damaged hair seeking extra conditioning
- Those who prefer mild, sulfate-free cleansers
Use caution if
- Vegans or those avoiding animal-derived ingredients
- Individuals with known sensitivity to coconut-derived surfactants
Usage tips
Safety summary
Generally recognized as safe for topical use in cosmetics at typical concentrations. Rare reports of mild irritation or allergic reactions, primarily due to the cocamidopropyl component.
Research notes
Limited peer-reviewed studies specifically on this compound, but its components (hydrolyzed collagen and cocamidopropyl betaine) are well-studied and considered safe. Evidence for conditioning benefits is largely anecdotal and formulation-dependent.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Shampoos, Conditioners, Hair masks, Body washes, Facial cleansers
- Environmental note
- The collagen component is typically sourced from animal by-products, which may have sustainability implications. The coconut-derived part is renewable.
Good to know
- Despite its long name, this ingredient is not a pure collagen but a modified protein derivative.
- It is often used in combination with other conditioning agents for a balanced formula.
