Frequently Asked Questions
What is dodecamethylpentasiloxane used for?
Dodecamethylpentasiloxane (MD3M, CAS 141-63-9) is a linear methylsiloxane fluid used as a low-viscosity silicone carrier and spreading/emollient fluid in personal-care and industrial formulations. It is valued for its volatility profile, low surface tension, and clean evaporation. Specific application suitability should be confirmed against the product CoA and SDS.
What is CAS number 141-63-9?
CAS 141-63-9 identifies dodecamethylpentasiloxane, a five-silicon linear siloxane with molecular formula C12H36O4Si5. It belongs to the silicone fluids and oils family. Always reference the CAS number on RFQs to ensure correct grade and identity matching.
What is the boiling point of dodecamethylpentasiloxane?
Dodecamethylpentasiloxane is a volatile linear siloxane; its boiling point and full physical-property set are listed on the lot-specific Certificate of Analysis and SDS we supply with each shipment. Request the current datasheet for exact boiling point, density, and viscosity values for the grade quoted.
How is dodecamethylpentasiloxane supplied in bulk?
RawSource supplies dodecamethylpentasiloxane to manufacturers in industrial volumes, typically drums, IBC totes, and larger formats. Packaging, minimum order quantity, and lead time are confirmed at quotation. Submit a bulk RFQ with your target volume for current availability.
What is the difference between dodecamethylpentasiloxane and decamethyltetrasiloxane?
Both are linear methylsiloxane fluids that differ in chain length: decamethyltetrasiloxane (MD2M) has four silicon atoms while dodecamethylpentasiloxane (MD3M) has five, giving MD3M a higher boiling point and viscosity. Select the grade by the volatility and spreading profile your formulation requires. Confirm specifications on the CoA before ordering.
