Ingredient review
Chitosan Rice Branamide Hydroxypropyltrimonium Chloride
INCI: Chitosan Rice Branamide Hydroxypropyltrimonium Chloride
A gentle conditioning ingredient that forms a protective film on hair, reducing frizz and improving softness without heavy buildup.
In plain English
This ingredient is a modified version of chitosan, which comes from the shells of shrimp and crabs, combined with a compound from rice bran oil. It has a positive electrical charge that helps it stick to the negatively charged surface of hair strands. Once applied, it forms a thin, flexible film that smooths the hair cuticle, reduces static, and makes hair feel softer and easier to comb. It is often used in rinse-off and leave-on hair products.

Quick decision guide
Useful, but context matters
Chitosan Rice Branamide Hydroxypropyltrimonium Chloride 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 Chitosan Rice Branamide Hydroxypropyltrimonium Chloride.
- 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 cationic polymer created by chemically bonding chitosan (a natural polysaccharide from crustacean shells) with a rice bran fatty acid derivative and a quaternary ammonium group. This structure gives it strong affinity for hair and skin surfaces.
How it works
The positively charged quaternary ammonium group binds to the negatively charged surfaces of hair and skin, forming a thin, flexible film. This film smooths the hair cuticle, reduces friction between strands, and helps prevent moisture loss, leading to softer, more manageable hair with less static and frizz.
Pros
Excellent detangling
The positive charge helps the ingredient cling to hair, reducing friction and making combing easier, especially for wet hair.
Frizz control without heaviness
Forms a lightweight film that smooths the cuticle and reduces static, so hair stays soft and manageable without feeling greasy or stiff.
Cons and cautions
Potential buildup
Because it sticks strongly to hair, using it too often or in high concentrations may lead to product buildup, making hair feel dull or heavy over time.
Animal-derived source
Traditional chitosan comes from crustacean shells, which may not be suitable for vegans or those with shellfish allergies, though some biotech versions exist.
Best for
- People with dry, frizzy, or damaged hair seeking extra smoothness
- Those who want a gentle conditioning agent that doesn't weigh hair down
Use caution if
- Individuals with shellfish allergies should check with their dermatologist, as chitosan is derived from crustacean shells
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. Low irritation and comedogenic risk. Individuals with shellfish allergies should exercise caution due to the chitosan source.
Research notes
Studies on chitosan derivatives show good biocompatibility and film-forming properties. Specific data on this exact compound is limited, but the class of quaternized chitosan polymers is well-studied for hair conditioning.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. No specific restrictions known at typical use levels.
- Common uses
- Shampoos, Conditioners, Leave-in treatments, Hair masks
- Environmental note
- Chitosan is derived from a renewable source (shellfish waste), but its production involves chemical modification. Biodegradability may vary depending on the specific modification.
Good to know
- This ingredient is often listed near the middle or end of an ingredient list, as it is used at low concentrations.
- It is compatible with many other conditioning agents and can be used in both rinse-off and leave-on products.
