RAC adopts opinion on harmonized classification of MBIT

July 24, 2018

On June 15, the European Chemicals Agency (ECHA) announced that its Risk Assessment Committee (RAC) adopted opinions on harmonized classification and labeling of 13 substances. Amongst others, RAC agreed to classify MBIT (2-methyl-1,2-benzisothiazol3(2H)-one) as a substance that may cause an allergic skin reaction (Skin Sens. 1A), with a specific concentration limit (SCL) of 15 ppm.

MBIT has recently been approved as a new active substance for use in biocidal products for product-type 6 (preservatives for products during storage) under the BPR.

Dow Microbial Control strongly contests the basis of the decision for an SCL of 15 ppm for skin sensitization, since the available data clearly supports the use of the generic concentration limit (GCL) of 1000 ppm. Dow Microbial Control is currently evaluating options for the continued defense of MBIT as an effective preservative under the BPR.
