    Benzethonium Chloride CAS 121-54-0

    Benzethonium Chloride (CAS 121-54-0, EC 204-479-9) is a quaternary ammonium ingredient used in personal-care, hygiene and specialty formulations where cationic surface activity and antimicrobial performance are required. It should not be confused with benzalkonium chloride or methylbenzethonium chloride. Purity or active content, physical form and packaging should be confirmed for the selected grade. COA, TDS and SDS may be provided on request.

    Product Overview

    Benzethonium Chloride is a cationic quaternary ammonium ingredient used in selected personal-care, hygiene and specialty formulations. Because antimicrobial and antiseptic uses can be regulated, confirm the supplied grade and destination-market requirements before formulation.

    Assess compatibility with anionic ingredients and confirm the permitted use level and documentation for the destination market.

    • Dispose of residues and empty packaging in accordance with local regulatory requirements.

    FAQ - Technical & Supply Chain

    • Q:

      Is Benzethonium Chloride the same as Benzalkonium Chloride?

      A: No. Benzethonium Chloride (CAS 121-54-0) is a defined quaternary ammonium compound, whereas Benzalkonium Chloride is commonly a mixture of alkylbenzyldimethylammonium chlorides. They should not be exchanged without confirming the intended formulation and applicable requirements.
    • Q:

      Is Benzethonium Chloride compatible with anionic surfactants?

      A: As a cationic quaternary ammonium ingredient, Benzethonium Chloride can interact with soaps and anionic surfactants. This can alter solution clarity or reduce the intended functional contribution; assess compatibility in the complete formula before selecting it.
    • Q:

      Which grade details should accompany Benzethonium Chloride selection?

      A: Confirm the material identity, assay basis, water or loss-on-drying limit, appearance, physical form and any application-specific impurity limits. The final formula and destination-market requirements determine whether a particular grade and its documentation are suitable.
