Fumed Silica
Colloidal Silicon Dioxide and Precipitated Silica USP NF BP Ph Eur EP Suppliers
Silicon dioxide is generally recognized as safe by the FDA. In the pharmaceutical industry, colloidal silicon dioxide is used in tablet-making, including use as an anti-caking agent, adsorbent, disintegrant, or glidant to allow powder to flow freely when tablets are processed.
Fumed silica also known as pyrogenic silica is a very fine particulate or colloidal form of silicon dioxide. It is prepared by burning SiCl4 in an oxygen-rich hydrogen flame to produce a "smoke" of SiO2.
Hydrophilic fumed silica is used with increasing success in high technology fields including pharmaceuticals, polyester, silicone, paints and coatings.
Hydrophobic fumed silica has a low moisture adsorption, excellent dispersibility, and ability to adjust rheological behavior, even that of polar systems.
Precipitated silica is an amorphous form of silica. It is a white, powdery material, produced by precipitation from a solution containing silicate salts. We offer it in various bulk density.
Specifications of Colloidal Silicon Dioxide USP NF Grade:
SiO2 --- 60.08
(This is a fumed silica grade.)
Silica CAS 7631-86-9
Colloidal Silicon Dioxide is a submicroscopic fumed silica prepared by the vapor-phase hydrolysis of a silicon compound. When ignited at 1000 for 2 hours, it contains not less than 99.0 percent and not more than 100.5 percent of SiO2.
Packaging and storage: Preserve in well-closed containers.
Identification:
A: Transfer about 5 mg to a platinum crucible and mix with about 200 mg of anhydrous potassium carbonate. Ignite at a red heat over a burner for about 10 minutes, and cool. Dissolve the melt in 2 mL of freshly distilled water, warming if necessary, and slowly add 2 mL of ammonium molybdate to the solution: a deep yellow color is produced.
B: [Caution: Avoid contact with o-tolidine when performing this test, and conduct the test in a wellventilated hood.] Place 1 drop of the yellow silicomolybdate solution obtained in Identification test A on a filter paper and evaporate the solvent. Add 1 drop of a saturated solution of o-tolidine in glacial acetic acid to reduce the silicomolybdate to molybdenum blue, and place the paper over ammonium hydroxide: a greenish blue spot is produced.
pH: between 3.5 and 5.5, in a 1 in 25 dispersion.
Loss on drying: Dry it in a tared platinum crucible at 105 for 2 hours: it loses not more than 2.5% of its weight. Retain the dried specimen, in the crucible, for the test for Loss on ignition.
Loss on ignition: Ignite the portion of Colloidal Silicon Dioxide, retained from the test for Loss on drying, at 1000C ± 25C to constant weight: the previously dried Colloidal Silicon Dioxide loses not more than 2.0% of its weight.
Arsenic: To pass the test. The limit is 8 microg per g.
Assay: Transfer about 500 mg of Colloidal Silicon Dioxide to a tared platinum crucible, ignite at 1000C ± 25C for 2 hours, cool in a desiccator, and weigh. Add 3 drops of sulfuric acid and add enough alcohol to just moisten the sample completely. Add 15 mL of hydrofluoric acid, and in a well-ventilated hood evaporate on a hot plate to dryness, using medium heat (95C to 105C) and taking care that the sample does not spatter as dryness is approached. Heat the crucible to a red color with the aid of a Bunsen burner. Ignite the residue at 1000 ± 25 for 30 minutes, cool in a desiccator, and weigh. If a residue remains, repeat the procedure, beginning with “add 15 mL of hydrofluoric acid.” The weight lost by the assay specimen, previously ignited at 1000C± 25C, represents the weight of SiO2 in the portion taken.
Specifications of Silicon Dioxide USP NF Grade:
(This is a precipitated silica grade.)
SiO2xH2O
Anhydrous 60.08
Silicon Dioxide is obtained by insolubilizing the dissolved silica in sodium silicate solution. Where obtained by the addition of sodium silicate to a mineral acid, the product is termed silica gel; where obtained by the destabilization of a solution of sodium silicate in such manner as to yield very fine particles, the product is termed precipitated silica. After ignition at 1000C for not less than 1 hour, it contains not less than 99.0 percent of SiO2.
Packaging and storage: Preserve in tight containers, protected from moisture.
Labeling: Label it to state whether it is silica gel or precipitated silica.
Identification: Transfer about 5 mg to a platinum crucible, mix with about 200 mg of anhydrous potassium carbonate, ignite at a red heat over a burner for 10 minutes and cool. Dissolve the melt in 2 mL of recently distilled water, warming if necessary, and slowly add 2 mL of ammonium molybdate: a deep yellow color is produced.
pH: between 4 and 8, in a slurry (1 in 20).
Loss on drying: Dry it at 145 for 4 hours: it loses not more than 5.0% of its weight.
Loss on ignition: Ignite about 1 g of it, previously dried and accurately weighed, at 1000C for not less than 1 hour: it loses not more than 8.5% of its weight.
Chloride: Boil 5 g in 50 mL of water under a reflux condenser for 2 hours, cool, and filter. A 7-mL portion of the filtrate shows no more chloride than corresponds to 1.0 mL of 0.020 N hydrochloric acid (0.1%).
Sulfate: A 10-mL portion of the filtrate obtained in the test for Chloride shows no more sulfate than corresponds to 5.0 mL of 0.020 N sulfuric acid (0.5%).
Arsenic: To pass the test. --- The limit is 3 ppm.
Heavy metals: To pass the test. --- The limit is 0.003%.
Assay: Transfer about 1 g of Silica Gel to a tared platinum dish, ignite at 1000 for 1 hour, cool in a desiccator, and weigh. Carefully wet with water, and add about 10 mL of hydrofluoric acid, in small increments. Evaporate on a steam bath to dryness, and cool. Add about 10 mL of hydrofluoric acid and about 0.5 mL of sulfuric acid and evaporate to dryness. Slowly increase the temperature until all of the acids have been volatilized and ignite at 1000C. Cool in a desiccator, and weigh. The difference between the final weight and the weight of the initially ignited portion represents the weight of SiO2.

Specifications of Silicon Dioxide FCC Food Grade:
Synthetic Amorphous Silica
SiO2 Formula weight 60.08
INS: 551 CAS 7631-86-9
DESCRIPTION
Silicon Dioxide occurs as an amorphous substance that shows a noncrystalline pattern when examined by X-ray diffraction. It is produced synthetically, either by a vapor-phase hydrolysisprocess, yielding fumed silica, or by a wet process, yielding precipitated silica, silica gel, colloidal silica, or hydrous silica. Fumed silica is produced in an essentially anhydrous state, whereas the wet-process products are obtained as hydrates or contain surface-adsorbed water.
Fumed silica occurs as a white, fluffy, nongritty powder of extremely fine particle size and is hygroscopic. The wet process silicas occur as white, fluffy powders or as white, microcellular beads or granules and are hygroscopic or absorb moisture from the air in varying amounts. All these forms of Silicon Dioxide are insoluble in water and in organic solvents but they are soluble in hydrofluoric acid and in hot, concentrated solutions of alkalies.
Function: Anticaking agent; defoaming agent; carrier; conditioning agent; chillproofing agent in malt beverages; filter aid.

Exposure Limits: US OSHA PEL: 6 mg/m3
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 low.
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.
