    Product Description

    Cetrimonium Chloride (CTAC) CAS 112-02-7 is a cationic quaternary ammonium surfactant with EINECS 203-928-6 and molecular formula C19H42ClN.

    Synonyms: Cetyltrimethylammonium chloride; Hexadecyltrimethylammonium chloride; Cetrimonium Chloride; CTAC.

    CAS: 112-02-7.

    Molecular formula: C19H42ClN.

    It is usually supplied as a clear to pale yellow solution or a more concentrated paste depending on active content.

    It is also called cetyltrimethylammonium chloride or hexadecyltrimethylammonium chloride.

    It is mainly used as a conditioning and antistatic agent in hair conditioners, conditioning rinses, creams, and cationic personal care formulations.

    It is also used in selected emulsified systems and industrial surfactant applications where cationic surface activity is required.

    It 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.

    Confirm active content, appearance, pH, water content, free amine, and related impurities or residual solvent.

    As a cationic surfactant, it can interact with anionic materials, so compatibility should be evaluated in the target formulation.

    Store 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.

    Confirm packaging suitable for the supply form and active content, and follow the current SDS.

    Every batch is checked for active content, appearance, pH, water content, free amine, and related impurities, with COA/TDS/SDS supplied per grade.

    Confirm active content, supply form, pH, packaging, and grade as required.

    FAQ - Technical & Supply Chain

    • Q:

      What is Cetrimonium Chloride CAS 112-02-7?

      A: 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.
    • Q:

      What is Cetrimonium Chloride mainly used for?

      A: 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.
    • Q:

      Why should active content and supply form be confirmed?

      A: 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.
    • Q:

      Is Cetrimonium Chloride compatible with anionic surfactants?

      A: 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.
    • Q:

      How should Cetrimonium Chloride be stored and handled?

      A: 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.
