Precipitated silica - special products for food industry
Glassven's products line offers a wide range of Special Precipitated Silicas used as free flowing, anti-caking, carrier and process aid with many fields of applications in the food industry,pharmaceuticals, nutraceuticals, flavors and fragrances, essential oils, among others.
PIROSIL? protects the particle's surface from the moisture, avoiding the caking and allowing the free flowing of the particles between them. Due to its porous structure can absorb large quantities of liquids and still remains as a free flow powder.
PIROSIL? Benefits：
● High chemical purity enabling them to be used as food additive for human consumption.
● Excellent optical whiteness.
● Absorbs up to three fimes its own weight and keep its original form.
● Its production process guarantees a product free of toxins.
● Does not modify the nutritional value of foods.
● Offers good compatibility with other ingredients.
● The amorphous structure of Precipitated Silicas make them safer to use than the natural crystalline forms.
● Combines high absorption capacity with high density, as a result very good flow properties.
● Improves the free flow properties of powders making them easy to manipulate, transport and use.
● Cost saving.
● Complies with the food industry standards and food safety certifications.

PIROSIL?PS-200
It is a Precipitated Silica widely used as free flowing and anti-caking agent,due to its reduced particle size and hygroscopic nature. It guarantees the flowabilily of the product and storage stability up to high environmental moisture conditions.
PIROSIL?PS-300
It is a Precipitated Silica specially designed to perform as free flowing agent, anti-caking and carrier due to its high absorption capacity. It has a very fine particle size (obtained by milling process), which enables it to be compatible with a wide products range, particulartly those that have been powdered.

Product quality
PIROSIL? Products meet all criteria established by the Food Chemical Codex (FCC) and the Food and Drug Administration (FDA) standards.
PIROSIL? grades are aimed to Food, Pharmaceutical, Nutraceutical and Personal Care applications.They count on Kosher and Halal certifications, which are renewed annually They also have the food safety certifications SC certificate.
Our production site and Quality Management System (QMS) have been accredited with ISO 9001:2008 certifiction, while our Food Management System (FMS) counts on ISO 22000:2005 HACCP and GMP certifications by SGS.
Packaging, Handling and Storage
PIROSIL? products are packed in 12,5Kg. and 20Kg. white paper bags, palletized and shrink wrapped. The bags can be handled in the same way as those of any other inert product.
PIROSIL? must be stored in confined, dry and odorless places. The maximum length of storage time is up to two years.
Physiological Effects and Product Safety
PIROSIL? Precipitated Silicas inert, non- toxic powder for the human being and the environment. The radiographic analysis shows the typical spectrum of an amorphous substance that does not contain crstalline elements.
