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]
Nonflammable | [Toxics Screening Level]
The initial threshold screening level (ITSL) for decamethylcyclopentasiloxane is 200 μg/m3, with annual averaging time. |
