Request SDS →Trisiloxane (CAS 18736-03-3) is the unsubstituted parent trisiloxane compound with the formula H8O2Si3. Not to be confused with octamethyltrisiloxane (MDM, CAS 107-51-7), which is the fully methylated industrial silicone fluid.
Frequently Asked Questions
What is trisiloxane?
Trisiloxane (CAS 18736-03-3) is the unsubstituted parent trisiloxane compound, formula H8O2Si3, consisting of three silicon atoms linked by two oxygen bridges (Si-O-Si-O-Si). It is the structural parent of the trisiloxane class rather than a specific commercial formulation.
Is trisiloxane the same as octamethyltrisiloxane (MDM)?
No. The parent trisiloxane (CAS 18736-03-3, H8O2Si3) should not be confused with octamethyltrisiloxane (MDM, CAS 107-51-7), which is the fully methylated industrial silicone fluid. If you need the volatile silicone fluid, specify MDM/octamethyltrisiloxane by CAS to avoid a mismatch.
Is trisiloxane a silicone?
Trisiloxane is a siloxane, the silicon-oxygen backbone class from which silicone fluids are built. Commercial trisiloxane products are typically substituted (e.g., methylated or organomodified) derivatives; the parent compound itself is the unsubstituted three-silicon backbone.
What are trisiloxane surfactants?
Trisiloxane surfactants are organomodified trisiloxane derivatives in which the silicone backbone is functionalized (commonly with polyether groups) to act as wetting and spreading agents. These are distinct products built on the trisiloxane backbone; specify the exact derivative and CAS when sourcing.
How do I specify the correct trisiloxane when ordering?
Because 'trisiloxane' can refer to the parent compound (CAS 18736-03-3) or to substituted derivatives such as MDM or trisiloxane surfactants, always order by CAS number and the intended derivative.
