What is Decamethylcyclopentasiloxane?
Decamethylcyclopentasiloxane (D 5) is a silicone compound with the molecular formula of [(CH 3) 2SiO] 5. It is a colorless and tasteless liquid with slight volatility.
Cyclopentasiloxane CAS No. 541-02-6, chemical formula C10H30O5Si5, molecular weight 370.77000, Chinese alias decamethylcyclopentasiloxane, liquid, boiling point 90 °C10 mm Hg(lit.), flash point 162 °F, density 0.958 g/mL at 25 °C(lit.), refractive index n20/D 1.396(lit.). Decamethylcyclopentasiloxane (cyclopentasiloxane) is a colorless, odorless, volatile liquid cyclic siloxane, safe and environmentally friendly, and has been widely used in health and beauty products , such as deodorants, antiperspirants, cosmetics, shampoos, body lotions, etc. Good compatibility with alcohol and most other cosmetic solvents.
Cyclopentasiloxane (D5), octamethylcyclotetrasiloxane (D4) and tetramethyltetravinylcyclotetrasiloxane (D4vi) are all important intermediate monomers, which can be combined with End-capping agents such as hexamethyldisiloxane, tetramethyldivinyldisiloxane (DVTMDS) or tetramethyldihydrodisiloxane are used for ring-opening copolymerization to prepare silicone oil, silicone rubber, silicone resin, etc. The purity of the monomer directly affects the quality of silicone oil, silicone rubber, etc., so controlling the purity of the monomer is one of the important technical links in the preparation of high-quality silicone materials, and the physicochemical data of these raw materials provides a reliable basis for its separation and purification process. .
Decamethylcyclopentasiloxane Uses
- It is classified as decycloyloxane. This liquid is commonly used in cosmetics, such as deodorants, sunscreens, hair gels and skin care products.
- Decamethylcyclopentasiloxane is becoming more and more common in hair conditioners because it makes hair easier to comb without breaking.
- Decamethylcyclopentasiloxane is also used as part of silicone based personal lubricants. D 5 is considered a emollient.
