| Decamethylcyclopentasiloxane Usage And Synthesis |
| 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 | Intermediate in the manufacture of high mol wt siloxane polymers. Carrier ingredient in personal care products; dry cleaning solvent. | | 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. | | 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 |
