DMC Reaches BPR Milestone with Submission of Biocidal Product Dossiers

Horgen, Switzerland - June 22, 2017 - Today, Dow Microbial Control, a business unit of The Dow Chemical Company (NYSE: DOW), submitted the dossiers for the authorization of biocidal products containing CMIT/MIT1 as the single active ingredient to the European Chemicals Agency under the Biocidal Products Regulation (BPR). The investment and support by Dow enables the industry to continue to use CMIT/MIT in Europe across the multiple applications supported in Dow’s BPR Biocidal Product dossiers. This submission initiates the extension of national approvals for three years beyond the July 1st, 2017 expiration date for products included in the dossier.

Our regulatory team’s experience in submitting product dossiers and our in-depth knowledge of CMIT/MIT brought us a step further in our BPR product registration support strategy for 19 active substances and multiple products Dow supports in the EU under the BPR.

Dow’s long-term support for CMIT/MIT continues

Dow invented CMIT/MIT and first brought it to the European market with KATHON™ Biocides in 1976. The submitted dossiers for solid, solvent- and aqueous-based products are based on extensive efficacy data and comprehensive risk assessments that determined the products offer the desired antimicrobial efficacy and are safe to use. The product family covers concentrations ranging from 1.5-14 percent, giving our customers the formulation flexibility they need.
