What is Cetrimonium Chloride CAS 112-02-7?

Cetrimonium Chloride is a cationic quaternary ammonium surfactant with CAS 112-02-7, EC 203-928-6, and molecular formula C19H42ClN. It is also known as cetyltrimethylammonium chloride, hexadecyltrimethylammonium chloride, or CTAC, and is usually supplied as a clear to pale yellow solution or concentrated paste depending on active content.

What is Cetrimonium Chloride mainly used for?

It is mainly used as a conditioning and antistatic agent in hair conditioners, conditioning rinses, creams, and cationic personal care formulations. It can also be used in selected emulsified systems and industrial surfactant applications where cationic surface activity is required.

Why should active content and supply form be confirmed?

Cetrimonium Chloride is supplied in different forms, including liquid solutions at various active contents and more concentrated paste or solid grades. Active matter, solvent or water content, and physical form all affect dosing, handling, and formulation behavior, so the supplied grade should be confirmed before ordering.

Is Cetrimonium Chloride compatible with anionic surfactants?

It is a cationic surfactant and can interact with anionic materials, potentially causing complex formation or reduced performance. Compatibility should be evaluated in the target formulation, especially when combining CTAC with anionic surfactants, polymers, or other charged ingredients.

How should Cetrimonium Chloride be stored and handled?

Store it in tightly closed original containers in a cool, dry, well-ventilated area away from excessive heat, direct sunlight, strong oxidizers, and incompatible anionic materials. Maintain package integrity, use appropriate PPE, and avoid prolonged skin or eye contact.

Cetrimonium Chloride CAS 112-02-7

Cetrimonium Chloride is a quaternary ammonium cationic surfactant mainly used as a formulation ingredient in conditioning and antistatic systems. It is commonly selected for hair care and related formulations where smooth feel, easier wet combing, antistatic performance, and cationic surface activity are required. Where a behenyl quaternary is specified, Behentrimonium Chloride is a related conditioning option. From a supply perspective, it may be offered in different active-content forms depending on formulation needs, with standard export packaging and routine documentation such as COA, TDS, and SDS available on request.

Typical Applications

Hair conditioning formulations where improved combing, softer feel, and reduced static are required.
Conditioning rinses, creams, and related cationic personal care systems.
Formulation systems requiring cationic surface activity and deposition performance.
Selected emulsified systems where a cationic conditioning effect is desired.

Specific end uses, use levels, and claim language should be evaluated according to local regulatory requirements and the intended formulation type.

Packaging

Cetrimonium Chloride is typically supplied in sealed containers suitable for liquid or solution-form material handling. Standard export packaging can be arranged according to active content, supply form, and order quantity. Clean container condition, sealed closure, and protection during storage and transport are important to maintain product consistency. For regular orders and bulk supply programs, packaging can be coordinated according to customer logistics requirements.

Storage

Store in a cool, dry, and well-ventilated place in tightly closed original containers. Keep away from excessive heat, direct sunlight, and sources of contamination. Maintain package integrity during storage and transport. For materials supplied in solution form, storage conditions should be managed to preserve uniformity and handling stability.
