Allgemeine Beschreibung
An oily liquid with an unpleasant odor. Toxic by ingestion and skin absorption. Used as a depilatory and in hair waving preparations.
Air & Water Reaktionen
Soluble in water and denser than water.
Health Hazard
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Brandgefahr
Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
Sicherheitsprofil
Poison by ingestion.
Moderately toxic by inhalation. When
heated to decomposition it emits toxic
fumes of SOx. See also SULFIDES and
MERCAPTANS.
