SDS MSDS Sheet of Silicone Oil or Dimethylpolysiloxane Manufacturers
Dimethylpolysiloxane Pure Suppliers
Silicone oil is any liquid polymerized siloxane with organic side chains. The most important member is polydimethylsiloxane. These polymers are of commercial interest because of their relatively high thermal stability and their lubricating properties. Silicone oils are primarily used as lubricants, thermic fluid oils or hydraulic fluids. They are excellent electrical insulators and, unlike their carbon analogues, are non-flammable. Their temperature stability and good heat-transfer characteristics make them widely used in laboratories for heating baths ("oil baths") placed on top of hotplate stirrers, as well as in freeze-dryers as refrigerants. Silicone oil is also commonly used as the working fluid in dashpots, wet-type transformers, diffusion pumps and in oil-filled heaters. Dimethicone or Simethicone is a related compound.
Typical Properties and Specifications of Silicone Oil:
Appearance: Clear, colorless fluid polymer useful as a stationary phase in gas chromatography and as an anti-foaming agent.
Viscosity: 350 or as prescribed by the buyer.
Relative density: 0.98
Specifications of Silicone BP Ph Eur:
1. Silicone Oil Used as a Lubricant BP Ph Eur
Silicone oil used as a lubricant is a poly(dimethylsiloxane) obtained by hydrolysis and polycondensation of dichlorodimethylsilane and chlorotrimethylsilane. Different grades exist which are characterised by a number indicating the nominal viscosity placed after the name.
Silicone oils used as lubricants have a degree of polymerisation (n = 400 to 1200) such that their kinematic viscosities are nominally between 1000 mm2?s and 30 000 mm2/s.
Appearance: Clear, colourless liquid of various viscosities.
Solubility: Practically insoluble in water and in methanol, very slightly soluble in anhydrous ethanol, miscible with ethyl acetate, with methyl ethyl ketone and with toluene.
A. Kinematic viscosity at 25C (see Tests).
B. Infrared absorption spectrophotometry.
Comparison silicone oil CRS.
C. Heat 0.5 g in a test-tube over a small flame until white fumes begin to appear. Invert the tube over a 2ndtube containing 1 mL of a 1 g/L solution of chromotropic acid, sodium salt in sulfuric acid so that the fumes reach the solution. Shake the 2nd tube for about 10 s and heat on a water-bath for 5 min. The solution is violet.
D. In a platinum crucible, prepare the sulfated ash using 50 mg. The white powder obtained gives the reaction of silicates.
Acidity: To 2.0 g add 25 mL of a mixture of equal volumes of anhydrous ethanol and ether, previously neutralised to 0.2 mL of bromothymol blue solution and shake. Not more than 0.15 mL of 0.01 M sodium hydroxide is required to change the colour of the solution to blue.
Viscosity: Determine the dynamic viscosity at 25C. Calculate the kinematic viscosity taking the relative density to be 0.97. The kinematic viscosity is within the range 95 per cent to 105 per cent of the nominal viscosity stated on the label.
Mineral oils: Place 2 mL in a test-tube and examine in ultraviolet light at 365 nm. The fluorescence is not more intense than that of a solution containing 0.1 ppm of quinine sulfate in 0.005 M sulfuric acid examined in the same conditions.
Phenylated compounds: The refractive index is not greater than 1.410.
Heavy metals: Maximum 5 ppm.
Volatile matter: Maximum 2.0 per cent, determined on 2.00 g by heating in an oven at 150C for 24 h. Carry out the test using a dish 60 mm in diameter and 10 mm deep.
The label states:
— the nominal viscosity by a number placed after the name of the product;
— that the contents are to be used as a lubricant.
2. Silicone Elastomer for Closures and Tubing BP Ph Eur:
Silicone elastomer complying with the following requirements is suitable for the manufacture of closures and tubing.
Silicone elastomer is obtained by cross-linking a linear polysiloxane constructed mainly of dimethylsiloxy units with small quantities of methylvinylsiloxy groups; the chain ends are blocked by trimethylsiloxy or dimethylvinylsiloxy groups.
The general formula of the polysiloxane is as defined in the monograph:
The cross-linking is carried out in the hot state:
— either with:
— 2,4-dichlorobenzoyl peroxide for extruded products; or
— 2,4-dichlorobenzoyl peroxide or dicumyl peroxide or OO-(1,1-dimethylethyl) O-isopropyl monoperoxycarbonate or 2,5-bis[(1,1-dimethylethyl)dioxy]-2,5-dimethylhexane for moulded products;
— or by hydrosilylation by means of polysiloxane with -SiH groups using platinum as a catalyst.
In all cases, appropriate additives are used such as silica and sometimes small quantities of organosilicon additives (α,ω-dihydroxypolydimethylsiloxane).
Appearance: Transparent or translucent material.
Solubility: Practically insoluble in organic solvents, some of which, for example cyclohexane, hexane and methylene chloride, cause a reversible swelling of the material.
A. Infrared absorption spectrophotometry by the multiple reflection method for solids.
Comparison silicone elastomer CRS.
B. Heat 1.0 g in a test-tube over a small flame until white fumes begin to appear. Invert the tube over a 2nd tube containing 1 mL of a 1 g/L solution of chromotropic acid, sodium salt in sulfuric acid so that the fumes reach the solution. Shake the 2nd tube for about 10 s and heat on a water-bath for 5 min. The solution is violet.
C. 50 mg of the residue of combustion gives the reaction of silicates.
If necessary, cut the material into pieces of maximum dimension on a side of not greater than 1 cm.
Solution S: Place 25 g in a borosilicate-glass flask with a ground-glass neck. Add 500 mL of water and boil under a reflux condenser for 5 h. Allow to cool and decant the solution.
Appearance of solution: Solution S is clear.
Acidity or alkalinity: To 100 mL of solution S add 0.15 mL of bromothymol blue solution. Not more than 2.5 mL of 0.01 M sodium hydroxide is required to change the colour of the indicator to blue. To a further 100 mL of solution S, add 0.2 mL of methyl orange solution. Not more than 1.0 mL of 0.01 M hydrochloric acid is required to reach the beginning of the colour change of the indicator from yellow to orange.
Relative density: 1.05 to 1.25, determined using a density bottle with anhydrous ethanol as the immersion liquid.
Reducing substances: To 20 mL of solution S add 1 mL of dilute sulfuric acid and 20 mL of 0.002 M potassium permanganate. Allow to stand for 15 min. Add 1 g of potassium iodide and titrate immediately with 0.01 M sodium thiosulfate using 0.25 mL of starch solution as indicator. Carry out a blank titration using 20 mL of water instead of solution S. The difference between the titration volumes is not more than 1.0 mL.
Substances soluble in hexane: Maximum 3 per cent.
Phenylated compounds: Place 2.0 g in a borosilicate-glass flask with a ground-glass neck and add 100 mL of hexane. Boil under a reflux condenser for 4 h. Cool, then filter rapidly through a sintered-glass filter (16). Collect the filtrate and close the container immediately to avoid evaporation. At wavelengths from 250 nm to 340 nm, the absorbance is not greater than 0.4.
Mineral oils: Place 2 g in a 100 mL conical flask containing 30 mL of a mixture of 5 volumes of ammonia and 95 volumes of pyridine. Allow to stand for 2 h, shaking frequently. Decant the pyridine solution and examine in ultraviolet light at 365 nm. The fluorescence is not greater than that of a solution containing 1 ppm of quinine sulfate in0.005 M sulfuric acid examined in the same conditions.
Volatile matter: Maximum 0.5 per cent for silicone elastomer prepared using peroxides; maximum 2.0 per cent for silicone elastomer prepared using platinum.
Weigh 10.0 g of the substance previously stored for 48 h in a desiccator over anhydrous calcium chloride. Heat in an oven at 200C for 4 h, allow to cool in a desiccator and weigh again.
Silicone elastomer prepared using peroxides complies with the following additional test:
Residual peroxides: Maximum 0.08 per cent calculated as dichlorobenzoyl peroxide.
Platinum: Maximum 30 ppm.
The label states whether the material was prepared using peroxides or platinum.

Environmental precautions: Do not let the product enter drains, soil or water sources.
Methods and materials used for containment Cleanup procedures and Storage:
Small Spill: Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to legal requirements.
Large Spill: Do not inhale vapors, mist, or gas. Avoid dust formation. Contain spilled material. Cover with an inert, non-combustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite). Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow to evacuate as per law.
Section 7: Handling and Storage
Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. Wash thoroughly after handling. Do not drink, eat or smoke while handling. Avoid contact with skin, eyes and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray.

Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like oxidizing agents, acids.
Section 8: Exposure Controls/Personal Protection
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne contaminants below the exposure limit.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator may be worn. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures: Maintain good housekeeping in work area. Dust deposits on floors and other surfaces may pick up moisture and cause the surfaces to become slippery and present safety hazards. Handle in accordance with good industrial hygiene and safety practice. Wash hands after handling.
