Dimethicone- ▸ Personal-care barrier / de-soaping film: a uniform protective film in hand creams and lotions at as little as 0.1%
- ▸ Polish glide fraction: the low-viscosity lubricant in a polish blend that eases application and rub-out
- ▸ Release agent / mold release with a coherent, low-migration film
- ▸ Heat-resistant industrial lubricant and hydraulic-fluid component (flash point >275 °C)
- ▸ Multi-function additive: antifoam, water-repellent, liquid dielectric and heat-transfer oil
Mid- and high-viscosity polydimethylsiloxane fluids (>= 5 cSt) are reported as not meeting GHS hazard-classification criteria. The grade-specific SDS governs. A full SDS is supplied with every shipment and on request; hazard status is confirmed against the grade-specific SDS.
Silicone Oil 100 cSt is the balanced grade: mid viscosity gives a coherent, more uniform film than the thin grades without the drag of the heavy ones. It is marketed directly into personal-care barrier films and into polish blends as the low-viscosity glide fraction, and serves as a release agent, heat-resistant lubricant and multi-function additive.
Frequently Asked Questions
What is cSt in silicone oil?
cSt is centistokes, the unit of kinematic viscosity. For silicone oil (PDMS, CAS 9006-65-9) the cSt value sets how thick the fluid flows; 100 cSt is a medium-viscosity dimethicone grade between the thin (5-10 cSt) and heavy (1,000+ cSt) fluids.
What is the viscosity of silicone oil 100 cSt?
Silicone Oil 100 cSt has a nominal kinematic viscosity of 100 centistokes, a medium-viscosity dimethicone fluid. Confirm the exact value and reference temperature on the lot CoA when ordering.
What is silicone oil 100 cSt used for?
Medium-viscosity PDMS grades like 100 cSt are used in lubrication, release, polish, and personal-care formulation where a balance of body and flow is needed. Match the viscosity grade to your specific application.
What is the CAS number for silicone oil 100 cSt?
Silicone oil (dimethicone, PDMS) carries CAS 9006-65-9 with repeating-unit formula (C2H6OSi)n. The 100 cSt label is the viscosity grade, not a distinct CAS; all dimethicone grades share this number.
Can silicone oil 100 cSt be supplied in bulk?
Yes. RawSource supplies 100 cSt silicone oil in drum, tote, and IBC quantities to manufacturers. Request a bulk quote with your target volume and packaging; CoA and SDS are available on request.
