Uses
Octamethylcyclotetrasiloxane and decamethylcyclopentasiloxane are major industrial products, which are either marketed as such or used for the production of polydimethylsiloxanes.
Uses
Intermediate in the manufacture of high mol wt siloxane polymers. Carrier ingredient in personal care products; dry cleaning solvent.
Definition
ChEBI: Decamethylcyclopentasiloxane is an organosilicon compound.
General Description
D5 Cyclomethicone is a cyclic siloxane, that has a silicon-oxygen bond in a cyclic arrangement and methyl groups attached with the silicon atom. It is used in the production of some silicon-based polymers that are widely used in various personal care products.
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Flammability and Explosibility
Non flammable
Toxics Screening Level
The initial threshold screening level (ITSL) for decamethylcyclopentasiloxane is 200 μg/m3, with annual averaging time.
