    Composition

    BIT in aqueous anionic dispersant.

    Features & Benefits

    Key Attributes
    • Long lasting bactericide:
      Non specific action means organisms are less liekly to develop resistance.
    • Low acute mammalian toxicity.
    • Contains no added formaldehyde.
    • Easy to use:
      Aqueous dispersion.
      Additives compatible with customer products and processes.
      Good flow properties.
      Non-flammable.
    • Broad pH compatibility:
      Effective over pH range 4-12.
    • Heat stability:
      PROXEL™ BD Preservative is temperature stable up to 80oC.

    Applications & Uses

    Coating Type
    Amount to Use

    The dose required to protect aqueous systems will depend on several factors.
    These include the type of product, its susceptibility to microbiological attack, the extent to which micro-organisms can gain access, the organisms present, the pH of the product, the temperature of storage and the length of time for which protection is required.


    In most new cases, trials are necessary to optimize the needs of an individual system.
    Typical addition levels for trial purposes are shown in Table 3.


    If higher levels are required, we recommend reference to the Safety Data Sheet.

    When To Add

    The exceptional stability of PROXEL™ BD Preservative to both heat and to pH variations normally permits its addition together with the water at an early stage of manufacture, since the non-volatility of BIT ensures no loss of antimicrobial activity when the product is subsequently heated.
    However, the antimicrobial activity of BIT may be affected by the presence of some oxidizing agents, for example, persalts or sulphites.

    Antimicrobial Properties

    Manufacturers of aqueous-based products need to prevent the growth of the many different types of micro-organisms that can occur in these systems. Thus, the requirement is for a broad-spectrum preservative.
    The effectiveness of PROXEL™ BD Preservative against a wide range of microorganisms is shown in Table 1.

    Dispersibility in Aqueous Systems

    Easily dispersible in all proportions.
