INCI: COCAMIDOPROPYLDIMONIUM HYDROXYPROPYL HYDROLYZED COLLAGEN
A gentle conditioning ingredient that helps detangle hair and soften skin without heavy buildup.
In plain English
This ingredient is a modified protein made from collagen (a structural protein found in skin and hair) and coconut oil. It is designed to stick to hair and skin, leaving them feeling smoother and softer. It also helps reduce static and tangles in hair, and can make cleansers feel less stripping.

Quick decision guide
Useful, but context matters
Cocamidopropyl Dimonium Hydroxypropyl 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 Dimonium Hydroxypropyl 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 a coconut-derived fatty acid (cocamidopropyl) with a modified collagen protein. The result is a positively charged molecule that clings to negatively charged hair and skin surfaces.
How it works
The positive charge of this ingredient attracts it to the negative charges on damaged hair and skin. It forms a thin, flexible film that smooths the cuticle, reduces friction, and locks in moisture. In cleansers, it also helps reduce irritation from stronger surfactants.
Pros
Excellent detangler
Reduces tangles and makes wet hair easier to comb through, minimizing breakage during washing.
Gentle on skin
Less irritating than many other conditioning agents, making it suitable for sensitive scalps and skin.
Cons and cautions
Potential buildup
On fine or low-porosity hair, frequent use can lead to a heavy, greasy feel that requires clarifying shampoo.
Not vegan-friendly
Derived from animal collagen, so it is not suitable for vegan or cruelty-free routines.
Best for
- Those with dry, damaged, or chemically treated hair
- People looking for a mild conditioner in sulfate-free shampoos
Use caution if
- Strict vegans or those avoiding animal-derived ingredients
- Those with very fine hair prone to product buildup
Usage tips
Safety summary
Considered safe for use in rinse-off and leave-on products at typical concentrations. Rare reports of mild irritation are usually linked to the cocamidopropyl component, but overall risk is low.
Research notes
Limited peer-reviewed studies specifically on this compound, but its components (hydrolyzed collagen and cocamidopropyl derivatives) have a long history of safe use in cosmetics. Anecdotal evidence supports its conditioning benefits.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and most major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Shampoos, Conditioners, Hair masks, Body washes, Facial cleansers
- Environmental note
- The collagen source is typically a byproduct of the meat industry, which may be considered more sustainable than virgin materials, but it is not plant-based.
Good to know
- This ingredient is often listed near the end of ingredient lists because it is used in low concentrations.
- It is sometimes labeled as 'Hydrolyzed Collagen' on natural-focused products, but the cocamidopropyl modification makes it more effective as a conditioner.
