DODECAMETHYLPENTASILOXANE(Cas 141-63-9) Usage

Chemical Properties

clear colorless liquid

Uses

A non-cyclic polydimethyl siloxane. Study shows that it can be transformed by a specific microflora and in the natural environment degraded by mechanisms similar to other organic compounds.

Definition

ChEBI: An organosiloxane that is pentasiloxane in which all the hydrogens have been replaced by methyl groups. Metabolite observed in cancer metabolism.
