Определение

ChEBI: A macromolecule composed of repeating propyleneoxy units.

Общее описание

Colorless liquid that is odorless or has a mild sweet odor. May float or sink in water.

Профиль реактивности

Poly(propylene glycol) is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.

Угроза здоровью

The compound has a very low toxicity; few, if any, symptoms will be observed. Contact of liquid with eyes causes slight transient pain and irritation similar to that caused by a mild soap.

Профиль безопасности

Poison by intraperitoneal and intravenous routes.When heated to decomposition it emits acrid smoke and irritating fumes.
