Decamethylcyclopentasiloxane Chemical Properties,Usage,Production

Chemical Properties

liquid

Uses

A cyclic volatile methylsiloxane (cVMS) used in cosmetic and personal care products. Used in dermal exposure and inhalation toxicity study.

Uses

cyclopentasiloxane is incorporated into a formulation for its emollient and solvent activity.

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.
