The
first product containing sodium DDC was registered in 1949, and
the first product containing potassium DDC was registered in 1980.
For a list of the current products, please see Appendix A. The DDC
Salts case consists of two PC codes: 034803 (potassium dimethyldithiocarbamate,
or KDDC) and 034804 (sodium dimethyldithiocarbamate, or NaDDC).
There are 25 active potassium DDC products and 14 active sodium
DDC products. There are no inert uses and no pending registrations.
DDC Salts act as materials preservatives for fuels, metalworking
fluids, paints, coatings, adhesives, cloth, and paper/paperboard;
they act as antifoulants/slimicides in a variety of liquids including
industrial/commercial cooling water, air washer water, sugar mill
pulp/process water, marine heat exchangers, gas/oil recovery fluid,
industrial wastewater treatment systems, industrial water purification
systems, reverse osmosis water systems, and pasteurizer cooling
water. Their main uses are as antifoulants in industrial cooling
and air washer water systems, as well as pulp and paper mills and
gas/oil drilling muds.
Several uses of DDC Salts are pending
cancellation as of the publication of this document, including all
wood-preservative and paints/coatings uses, as well as preservation
of cloth and alginate paste.
