Physical dangers

Chemical dangers
Decomposes on heating. This produces toxic fumes including sulfur oxides, nitrogen oxides and sodium oxide. The substance is a weak base.

Formula: (C₂H₅)₂NCS₂Na / C₅H₁₀NNaS₂
Molecular mass: 171.3
Melting point: 90-102°C
Relative density (water = 1): 1.1
Relative vapour density (air = 1): 5.9
Solubility in water: soluble

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by ingestion. Effects of short-term exposure The substance is irritating to the skin, eyes and upper respiratory tract.	Inhalation risk Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly when dispersed. Effects of long-term or repeated exposure See Notes.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by ingestion.

Effects of short-term exposure
The substance is irritating to the skin, eyes and upper respiratory tract.

Inhalation risk
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly when dispersed.

Effects of long-term or repeated exposure
See Notes.

OCCUPATIONAL EXPOSURE LIMITS
MAK: (inhalable fraction): 2 mg/m³; peak limitation category: II(2); sensitization of skin (SH); pregnancy risk group: D

ENVIRONMENT
The substance is very toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment.

NOTES
The reaction with nitrosating agents can result in the formation of carcinogenic N-nitrosodiethylamine (DFG 2008). This substance is usually commercially available as a solution. Decomposes slowly in water or acidic solutions forming carbon disulfide and amines. See ICSC 0022. Other CAS numbers: 20624-25-3 (trihydrate). Use of alcoholic beverages enhances the harmful effect.
