Structure

Schematic formula:

Properties

Appearance    (1), solid.

Solubility    soluble in water.

Stability    stable.

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

GHS (Rev.7) label:  

Generally, irritation is lower than the corresponding carbon chain alkylbenzene sulfonate.

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

Biodegradability    biodegradable.

Characteristics    excellent foaming, cleansing, emulsifying, wetting, dispersing, solubilizing, permeating abilities.

Note    (1), Avoid using in children products, such as shower gels, shampoo, skin care products, and so on.
