Chemical Numbering System

CASRN: 61788-85-0

EINECS: 500-147-5

Molecular Formula & Molecular Weight

Molecular Formula: N/A

Molecular Weight: N/A


Basic component:


Appearance    (1), liquid to solid.

Solubility    slightly soluble in water (dispersible in water) to soluble in water. The solubility increases with the increase of EO number.

Stability    stable. Under strong acid or strong alkali condition, easily hydrolyzed.

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

GHS (Rev.9) label:

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

Biodegradability    biodegradable.

Characteristics    excellent emulsifying, dispersing, solubilizing, lubricating abilities. Performance is related to EO number.

Note    (1), The by-product 1,4-dioxane is a possible carcinogen. Generally, can be acceptable when concentration of 1,4-dioxane is less than 30ppm or less.

(2), Be careful with using in children's products.
