Replacement of Arsenic Compounds

The move away from OBPA is evident in the product lines sold by Akcros Chemicals, a company that addresses both the material protection and hygienic surface markets. Akcros sells biocides imder the Intercide name for use in PVC, polyolefins and other polymer types. Between them these products can deal with all the various types of microorganism (fungi, bacteria, yeasts). 

The active ingredient in the BTX grades is Bethoguard , or 3-benzothien-2-yl-5,6-dihydro- 

2 oxathiazine 4-oxide, made by Janssen Pharmaceuticals in Belgium. Other active ingredients used by Akcros over the last three or four years have included zinc pyrithione in 

Intercide DP8438F and Intercide DP8434F, both targeted at polyolefin applieations such as rubbish sacks. 

Akcros issues a certificate saying Saniproofed by Intercide for users of their biocides to display in the form of a logo on their products.
