| Octamethyltrisiloxane Usage And Synthesis |
| Chemical Properties | Octamethyltrisiloxane is clear colourless liquid. |
| Uses | Octamethyltrisiloxane is a linear silicone oligomer. It is used as an excipient Dimethicones in pharmaceutical and cosmetic applications can provide long lasting lubricant, smooth feel and spreads easily. Studies demonstrate that it is able to maintain the conformational stability of certain adsorbed proteins such as bovine serum albumin (BSA). Used in the methylation of mercury(II) salts. |
| Application | As a basis for silicone oils or fluids designed to withstand extremes of temp; as a foam suppressant in petroleum lubricating oil. |
| Definition | ChEBI: Octamethyltrisiloxane is an organosiloxane that is trisiloxane in which all the hydrogens have been replaced by methyl groups. |
| General Description | Poly(dimethylsiloxane) (PDMS), also known as dimethicone, is an organosilicon compound that is widely used as a siloxane based elastomer. It is a hydrophobic material with attractive physical and chemical properties such as elasticity, optical transparency, tunable surface chemistry, and low electrical conductivity. |
| Flammability and Explosibility | Flammable |
| Purification Methods | Distil it twice, the middle fraction from the first distillation is again distilled, and the middle fraction of the second distillation is used.
