What is Behentrimonium Chloride CAS 17301-53-0?

Behentrimonium Chloride, also called BTAC or docosyltrimethylammonium chloride, is a cationic quaternary ammonium compound with a C22 alkyl chain. It has molecular formula C25H54ClN, EC number 241-327-0, and molecular weight about 404.16 g/mol.

Why is Behentrimonium Chloride used in hair-care formulations?

Its long C22 chain gives strong substantivity to the hair surface, helping to reduce static and improve wet and dry combability. It is commonly used to build conditioning, detangling, and softening performance in shampoos, conditioners, hair masks, and leave-in products.

What is the difference between Behentrimonium Chloride and Behentrimonium Methosulfate?

Both are C22 quaternary ammonium conditioning agents, but the chloride and methosulfate counterions can affect solubility, compatibility, and formulation behavior. They should not be treated as direct drop-in replacements without formulation testing.

What supply forms and active contents should be confirmed?

Behentrimonium Chloride can be offered as a white to off-white solid, powder, flake, or pastille, and may also be supplied as a compounded lower-active blend. Confirm active content, physical form, amine hydrochloride, ash, color, pH, and the intended cosmetic or personal care grade before ordering.

Where is Behentrimonium Chloride mainly used?

It is mainly used as a conditioning and antistatic raw material in rinse-off and leave-on hair care, conditioning shampoos, personal care emulsions, and cationic cream systems. It is an ingredient for formulated products, not a finished consumer product.

Behentrimonium Chloride CAS 17301-53-0

Behentrimonium Chloride (BTAC, CAS 17301-53-0) is supplied as a cationic conditioning and antistatic ingredient for hair-care and personal-care formulations. Formulators commonly evaluate it for conditioners, hair masks, rinses and other emulsified systems requiring a smoother feel, improved combability and reduced static. Available grade, active content and physical form should be confirmed against the formulation and target-market requirements. Where a fatty-alcohol conditioning raw material is specified, Behentrimonium Methosulfate is a related product to evaluate. COA, TDS and SDS support can be provided for the confirmed product. Send your target specification, application, quantity, packaging and destination for review and quotation.

Packaging

Behentrimonium Chloride is generally supplied in sealed packaging suitable for solid or high-active conditioning raw materials. Packaging is arranged according to the supply form, handling needs, and order quantity. Clean container handling and proper sealing are recommended to help maintain product stability during storage and transport. Standard export packaging and bulk supply arrangements can be coordinated for routine formulation raw material procurement.

Storage

Store in a cool, dry, and well-ventilated place in tightly closed original packaging. Keep away from excessive heat, direct sunlight, and sources of contamination. During storage and transportation, package integrity should be maintained and unnecessary exposure to moisture should be avoided. After opening, the container should be resealed promptly for normal material handling.
