What is silica colloidal anhydrous?
Silica Gel, Grade 923, 100-200 Mesh is a porous and granular form of silicon dioxide which is synthetically made from sodium silicate. In chemistry, the silica gel is used as a stationary phase in chromatography.
What is silica colloidal anhydrous used for?
Colloidal silicon dioxide is a substance that acquires additional properties during oxidation, which allows it to be used as an emulsifier. This substance prevents the clumping of food ingredients and non-food materials with a crumbly structure.
What is colloidal silica good for?
The applications range from surface treatment in the paper industry, to use as a polishing agent in the electronics industry and use as an additive for varnishes, coatings and paints to improve weather and abrasion resistance. It is also a common additive in cosmetics and in the food industry.
What is the difference between silica and colloidal silica?
Summary – Colloidal Silica vs Reactive Silica The key difference between colloidal silica and reactive silica is that colloidal silica is the polymeric form of silicon, whereas reactive silica is the non-polymeric form of silicon.
Can silica damage your kidneys?
If you are exposed to silica dust in the workplace, this can cause many chronic health problems including kidney damage and kidney failure. The more you are exposed, the greater the risk. It only takes a very small amount of airborne silica dust to create a significant health hazard.
What are side effects of silica?
Breathing in very small (“respirable”) crystalline silica particles, causes multiple diseases, including silicosis, an incurable lung disease that leads to disability and death. Respirable crystalline silica also causes lung cancer, chronic obstructive pulmonary disease (COPD), and kidney disease.
What does silica do to the body?
Silica is an important trace mineral that provides strength and flexibility to the connective tissues of your body — cartilage, tendons, skin, bone, teeth, hair, and blood vessels. Silica is essential in the formation of collagen, the most abundant protein found in your body.
What are the side effects of silica?
Does taking silica have side effects?
Silica has a very low risk for toxicity when taken orally. The EFSA note that even after administering very high doses of up to 9,000 milligrams of silica per kilogram of body weight, no adverse effects appeared.
Is it safe to drink silica?
Although consuming silica doesn’t appear to have negative effects, inhaling small particles of it can increase your risk of developing serious silica-related diseases, such as: Silicosis. Lung cancer.
What are the symptoms of silica deficiency?
Symptoms
- The hair becomes brittle, it loses its shine and falls out;
- The nails are brittle;
- The skin becomes thinner;
- The wrinkles occur;
- The person experiences from slower wound healing;
What do you need to know about silica anhydrous?
Silica colloidal anhydrous (colloidal silicium dioxide). What is it, harm, benefit, instructions for use Unlike other forms, colloidal silicon dioxide belongs to the hydroxyl group of substances.
How are the particles of colloidal anhydrous silica formed?
Colloidal anhydrous silica is formed by hydrolysis at over 1,000 °C. This is achieved by introducing chlorosilanes into an oxyhydrogen flame, producing SiO 2primary particles about 5–50 nanometers (10–9m) in size. In the flame, the primary particles fuse together permanently to form large units, or aggregates (100–1,000 nm in size).
Can a colloidal anhydrous silica be used in Europe?
HDK® N20 Pharma is fully registered a US Type IV Drug Master File. Additional Information European Union Colloidal anhydrous silica may be used as a direct food additive in accordance with Regulations (EU) No. 1129 and 1130/2011 (superseding Directive 95/2/EC).
What is the pH of colloidal silicon dioxide?
Ph. Eur. 6.2 (Silica, Colloidal Anhydrous). A light, fine, white or almost white, amorphous powder. It has a particle size of about 15 nm. Practically insoluble in water and in mineral acids except hydrofluoric acid; dissolves in hot solutions of alkali hydroxides.
