Regulatory evidence across markets

None of the 13 markets tracked here holds an imported rule under the name FORMAMIDINE SULFINIC ACID.

That is a statement about this inventory, not about the law: no imported rule is not evidence that a substance is permitted. A rule may exist under a different name, under a CAS or EC number this glossary entry does not carry, or in a dataset not yet imported.

Thiourea dioxide

Thiourea dioxide appears as a white or light-yellow odorless crystalline powder. Mp:126 °C. Soluble in water (27 g / L at room temperature). Decomposes exothermically at temperatures above 126 °C with the emission of noxious gases (sulfur oxides, ammonia, carbon monoxide, nitrogen oxides and hydrogen sulfide) and carbon dioxide. Extended exposure to temperatures above 50 °C and moisture may cause visible decomposition. Irritating to skin and mucous membranes. Corrosive to eye tissue. Used in leather processing, the paper industry, photographic industry, and in textile processing as a bleaching agent. — CAMEO Chemicals
