Proxel TN Preservative - Arxada - 2634-33-5

The product is effective in a wide range of industrial aqueous-based products. The combination of two active agents provides a quick microbial kill with long term protection. In addition, the “triazine” active agent gives enhanced head space protection in the container. Application areas include:

Synthetic polymer emulsions
Emulsion paints
Aqueous pigment dispersions
Water-based adhesives

Amount to Use

Table 3. Applications

Product	% PROXEL™ TN Preservative (w/w)
Emulsion Paints	0.05-0.2
Pigment dispersions: based on slurries	0.05-0.2
Synthetic polymer emulsions	0.05-0.2
Water-based adhesives	0.05-0.15

PROXEL™ TN Preservative should be added to the system as early in the process as possible but only after all heating stages are completed and the temperature of the product is less than 40°C. The concentration required to adequately preserve your product depends on several factors. These include the susceptibility of the system to microbiological degradation, the extent to which micro-organisms can gain access, the species involved, pH, temperature, and length of time for which protection is required.

A range of concentrations and applications is recommended in Table 3; however, it is recommended that a testing program be undertaken to determine the most costeffective dose for your application.

Testing should take into account chemical compatibility/stability, plant hygiene conditions, susceptibility of the product to contamination, and the typical organisms involved.

Antimicrobial Properties

The levels of product needed to prevent the growth of problem microorganisms are listed in Table 1; Minimum Inhibitory Concentrations (MICs) do not represent effective use levels but do indicate the broad spectrum of activity.

PROXEL™ TN Preservative has a non-specific mode of action which means that bacterial resistance is very unlikely to occur. Detailed information on the mode of action is available on request.

Active Agent

50% w/w “triazine” and 5.5% w/w 1,2-benzisothiazolin-3-one

Compatibility

Compatible and effective over pH range 4-12. Stable in the presence of amines.
Incompatible with some oxidizing and reducing agents e.g. persalts, sulphites etc.
