Thiourea Dioxide is a new type of reducing agent used in the printing and dyeing industry, synthetic fiber industry, polymerization additives, polyvinyl chloride stabilizers, photographic emulsion sensitizers, etc. It is a safe substitute for Sodium Hydrosulfite.

It is white crystal, slightly soluble in water, insoluble in organic solvent, and has a solubility of 3% in water at 25°C. The appearance of the product is white loose powder, non-toxic, non-volatile, non-flammable, and non-polluting to the environment.

1. Precautions for handling and storage:

Avoid formation of dust and aerosols. Do not breathe dust. Avoid contact with skin, eyes, and clothing. Wash thoroughly after handling. Provide appropriate exhaust ventilation at places where dust is formed.

Keep container closed when not in use. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances (Strong bases, Strong oxidizing agents). Keep it cool, ventilated, dry, and strictly prevent moisture, exposure and rain.

Tightly closed and away from sources of ignition and heat. The best storage conditions: relative humidity<80%, temperature<30°C. If this condition is exceeded, it is recommended to take cooling and dehumidification measures.

2. Thiourea Dioxide's decomposition control:
When heated to decomposition or under fire conditions to release nitrogen oxides, carbon monoxide, oxides of sulfur, carbon dioxide, nitrogen gas. Use water spray, dry chemical, carbon dioxide, or appropriate foam. Do not stay in dangerous zone without self-contained breathing apparatus. In order to avoid contact with skin, keep a safety distance and wear suitable protective clothing.

3. Disposal considerations:

The material should be disposed of by incineration in a chemical incinerator in compliance with national and regional requirements.
