Ingredient review
Chitosan Rice Branamide Sulfonate
INCI: Sodium Chitosan Rice Branamide Hydroxypropylsulfonate
A gentle, semi-synthetic ingredient that forms a protective film on hair and skin, improving feel and moisture retention without irritation.
In plain English
This ingredient is a modified version of chitosan (derived from shrimp or crab shells) combined with rice bran oil. It's been chemically tweaked to make it water-soluble and more effective in skincare and haircare. When applied, it leaves a thin, flexible film on your skin or hair that helps lock in moisture, smooths the surface, and reduces frizz. Think of it as a gentle, natural-ish coating that makes your hair shinier and your skin feel softer.

Quick decision guide
Useful, but context matters
Chitosan Rice Branamide Sulfonate 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 Sulfonate.
- 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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A semi-synthetic polymer created by chemically modifying chitosan (from crustacean shells) with rice bran oil and a sulfonate group. This modification makes it water-soluble and gives it film-forming and conditioning properties.
How it works
It deposits a thin, flexible film on the surface of hair or skin. On hair, this film smooths the cuticle, reduces static, and adds shine. On skin, it helps reduce water loss (transepidermal water loss, or TEWL) and leaves a soft, non-greasy feel. The sulfonate group also gives it mild cleansing and anti-static properties.
Pros
Gentle film former
Creates a protective layer on hair and skin without feeling heavy or sticky, making it suitable for daily use.
Multi-functional
Works as both a hair conditioner and skin moisturizer, simplifying formulations for those who prefer fewer products.
Cons and cautions
Shellfish origin
Derived from crustacean shells, which may be a concern for vegans or people with shellfish allergies.
Limited research
There is less published safety and efficacy data compared to more established conditioning ingredients like glycerin or silicones.
Best for
- People with dry or frizzy hair looking for smoothing and shine
- Those who want a gentle film-forming ingredient for sensitive skin
Use caution if
- Individuals with shellfish allergies (due to chitosan source)
- Strict vegans (animal-derived chitosan)
Usage tips
Safety summary
Generally considered safe for topical use at typical concentrations. The main concern is potential allergenicity for those with shellfish allergies. No significant irritation or comedogenicity reported.
Research notes
Research on this specific modified ingredient is limited, but chitosan derivatives in general have been studied for their film-forming and antimicrobial properties. More studies are needed to confirm long-term safety and efficacy.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and other major markets. No specific restrictions noted.
- Common uses
- Shampoos, Conditioners, Hair serums, Facial cleansers, Moisturizers
- Environmental note
- Chitosan is typically sourced from seafood industry waste, which can be seen as a sustainable practice. However, the chemical modification process may involve synthetic reagents.
Good to know
- The 'sulfonate' part makes it water-soluble, so it rinses off easily and won't build up on hair.
- It is often used in sulfate-free shampoos to improve foam quality and mildness.
