Structure

Properties

Appearance    (1), solid; (2), liquid.

Solubility    soluble in water.

Stability    stable in weak acid, hard water. Under strong acid or strong alkali, easily hydrolyze. Under alkaline conditions, ammonia is released.

Risk    Solid form: flammable material; irritation, low irritation to skin, eye. Harmful products of combustion are CO, CO2 and so on. Contact with strong oxidants, can cause to burn.

GHS (Rev.7) label:  

Ecology    may be hazardous to environment. Water body should be given special attention.

Biodegradability    biodegradable.

Characteristics    excellent wetting, permeating, emulsifying, dispersing, cleansing, foaming, solubilizing abilities. Good lime soap dispersing power. Suitable for neutral formula system.

Synthesis
