Advantages of Cocamidopropyl Hydroxysultaine
Gentle | Foaming | Thickening | Compatible — One Bottle Solves Multiple Formulation Challenges
Buy Cocamidopropyl Hydroxysultaine, choose Highassay—we are your trusted long-term partner in the field of daily chemical and personal care raw materials.
CHSB, as a soothing surfactant, has a free amine content of ≤0.5%, significantly lower than that of CAPB.While gentle in its own right, it also alleviate the irritation caused by other active ingredients.It is the preferred choice for products for sensitive skin and infants.
CHSB foams rapidly and rinses off easily, with a foaming speed approximately 30% faster than that of CAPB.Even in hard water areas,it still maintains stable, dense foam and excellent longevity.
CHSB serves as an excellent thickening and texturizing agent, significantly optimizing a product’s rheological properties and skin feel;For example, when compounded with AES, viscosity can be increased by 30%.At the same time, it excels at enhancing the softness of the skin and hair, as well as maintaining their moisture levels.
CHSB is compatible with anionic, nonionic, and amphoteric surfactants.It is particularly suitable for rinse-off product formulations and is the preferred choice of many formulators.
Our minimum order quantity is flexible.
We offer product packaging in various specifications:
- 50kg / 200kg Plastic Drums: Suitable for standard production
- IBC Totes / Tank Trucks: Suitable for large-scale procurement

Yes. The safety profile of CHSB is well-documented; it has been rated by the EWG as a low-hazard ingredient. It is non-carcinogenic, non-toxic, and safe for both humans and the environment. Furthermore, it is biodegradable.
Note: In very rare instances, the concentrated raw solution may cause mild eye irritation; this can be avoided by using the product in a diluted form.
Cocamidopropyl Hydroxysultaine remains stable across a relatively wide pH range; it exhibits cationic properties under acidic conditions and anionic properties under alkaline conditions, thereby significantly enhancing formulation flexibility. This is another key reason why it is well-suited for rinse-off products.
Yes. CHSB in shampoo is beneficial for the hair.
Its gentle properties protect both the hair and scalp from damage, imparting a natural luster to the hair while improving texture and reducing roughness and frizz.
It also effectively minimizes static electricity in the hair, leaving it looking voluminous yet tidy and more manageable after use. Suitable for use in all seasons, its performance remains unaffected by low temperatures.
No, Cocamidopropyl Hydroxysultaine is a sulfobetaine, and it is a sulfate-free ingredient.
Sulfates typically refer to surfactants such as SLS and SLES; compared to these sulfates, CHSB is milder and less irritating, while still maintaining excellent foaming and cleansing capabilities.
