Physical and chemical properties:
Dimethyl silicone is also known as methyl silicone oil and polydimethylsiloxane liquid. It appears as colorless transparent viscous liquid, being tasteless, odorless and non-toxic. The molecular formula is CH3 [Si (cH3) 2] nSi (CH3) 3. The average molecular weight is 5000 ~ 100000. Based on the differences on the molecular weight, kinematic viscosity varies from 1.0 × 10-6 ~ 100000 × 10-6 square meters / second. Long-term use temperature range is -50 ~ 180 ºC. In isolated air or inert gas, it can be subject to long-term use at 200 ºC. Viscosity coefficient: 0.31 ~ 0.61. Surface tension: 1.59 ~ 2.15 × 10-4N / cm. Dielectric constant (23 ºC, 100Hz): 2.18 ~ 2.17. Volume resistivity (23 °C): 1.0 × 1014 to 1.0 × 1016Ωcm3. Dielectric loss tangent (23 ºC, 100Hz):0.00002~0.00004. Breakdown voltage strength: 13.7 ~ 17.7kV / mm. It is soluble in benzene, toluene, xylene and ethyl ether, partially soluble in ethanol, butanol and acetone, insoluble in cyclohexanol, methanol, paraffin oil and vegetable oil. It has excellent hydrophobic moisture resistance, good light transmission, and chemical stability. Widely used in insulation, heat, moisture-proof filler, defoamer, mold release agent, lubricant and surface treatment agent. It is produced by the reaction between octamethylcyclotetrasiloxane and hexamethyldisiloxane in the presence of concentrated sulfuric acid or tetramethylammonium hydroxide catalyst.
Dimethicones are clear, colorless liquids available in various viscosities. Dimethicone is a fluid mixture of fully methylated linear siloxane polymers end-blocked with trimethylsiloxy units. Methicone is a linear monomethyl polysiloxane. Dimethicone are safe as used in cosmetic formulations, vulcanization.

Uses:
A silicone oil consisting of a mixture of fully methylated linear siloxane polymers end-blocking with trimethylsiloxy units. Commonly used in skin and hair products.
dimethicone is a form of silicone used to give products lubricity, slip, and good feel. It can also serve as a formulation defoamer and help reduce the feeling of greasiness that some creams leave on the skin immediately upon application. In addition, dimethicone is reported to protect the skin against moisture loss when used in larger quantities. It improves product flow and spreadability. In combination with other ingredients, dimethicone becomes a good waterproofing material for sunscreen emulsions, and helps reduce the greasiness often seen in high-SPF preparations.
Silicone (dimethicone) ointments are excellent water-protective agents because they have an extremely low surface tension and penetrate crevices in the skin to form a plastic-like barrier. Further, they are nontoxic, inert, stable, and water repellent. As such, they are useful as barrier creams in industry or wherever constant or frequent exposure to aqueous compounds is a problem. They will not, however, protect well against solvents, oils, or dusts.
