Colloidal silica is used in a broad range of industries and applications, including: Densification of concrete, cement, and other materials. Fine retention in paper manufacturing. Enhanced bonding of waterborne adhesives.
Is colloidal silica safe?
Colloidal silica is not classified as harmful, but as mildly irritating. Because the products can have a drying effect on the skin, protective gloves should always be used. In case of skin contact, wash the area of contact with plenty of water. The use of safety glasses is always recommended.
What is colloidal silica used for in tablets?
In the pharmaceutical industry, silicon dioxide (also known as colloidal silicon dioxide) has many uses in tablet-making: some include as an anti-caking agent, adsorbent, disintegrant, or glidant to allow powder to flow freely when tablets are processed. These compounds appear to be biologically inert.
Does silica have side effects?
One of the dangerous effects of silica exposure is a disease called silicosis, which can be contracted after just a few months of high exposure. Silicosis occurs when silica dust enters the lungs and causes the formation of scar tissue, reducing the lungs’ ability to take in oxygen.
Is silicic acid the same as silica?
Remember that silicic acid is a silicon-containing compound, but not all silicon-containing compounds are silicic acids. Therefore, applying silica or silicates is not the same as applying monosilicic acid.
What are silica particles?
Silica is one of the most common minerals in the earth’s crust. Glass, beach sand, silicone, and granite are all silica materials. The size of the airborne silica particles determines the amount of risk. Smaller particles can be inhaled deep into the lungs where they can cause damage.
Is silica a silicon dioxide?
Silicon dioxide (SiO2), also known as silica, is a natural compound made of two of the earth’s most abundant materials: silicon (Si) and oxygen (O2). Silicon dioxide is most often recognized in the form of quartz. It makes up more than 95 percent of known rocks on the planet.
How much silica should I take daily?
The Food and Drug Administration (FDA) recommends that you don’t consume more than 10-30 grams, or 2% of your daily food intake (500-1,500 grams), of silica per day.
What is Levasil?
Levasil SP3089 is an alkaline, aqueous dispersion of colloidal silica that is approximately 50% solids by weight. The silica dispersion is sodium stabilized and the amorphous silica particles carry a negative surface charge. The physical appearance of the dispersion is a white liquid, slightly more viscous than water.
Why is silica bad for you?
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.
Is silica good for the heart?
Silica has been shown to help your heart and immune system: Recent research has found that silica can improve your heart health by reducing the risk of atherosclerosis, also known as hardening of the arteries.
Can silica damage your kidneys?
Silica dust particles are tiny, over 100 times smaller than the sand you see on the beaches. 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.
What are the side effects of colloidal silicon dioxide?
People can experience adverse effects of silicon dioxide if they inhale the fine particles. Long-term exposure to silica dust may pose a serious risk to health.Adverse effects silicosis, a progressive, irreversible lung disease. lung cancer. chronic obstructive pulmonary disease, or COPD. increased risk of tuberculosis.
How long does it take for silica to work?
How long do I need to take silica supplements before noticing results? A. Results vary between individuals and formulas. Some people experience benefits in as little as four to six weeks, while it takes as long as 12 weeks for others.
How do you make colloidal silica?
Colloidal silica was prepared by peptizing a hydro-wet gel obtained with sodiumsilicate solution in a mixture with nitric acid and pure water. Prepared samples exhibited a fairly uniform particle size of ca. 20 nm and could be concentrated up to over 20 wt% SiO2 by ultrafiltration.

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.
How do you remove colloidal silica from water?
SILICA REMOVAL Dissolved silica is best removed through reverse osmosis, while colloidal silica is best removed through ultrafiltration. It is always important to have your water tested for silica by a laboratory, in order to determine both the concentration and state of the silica present.
What is colloidal silica made from?
In the most general terms colloidal silica is a dispersion of amorphous silicon dioxide (silica) particles in water. These amorphous silica particles are produced by polymerizing silica nuclei from silicate solutions under alkaline conditions to form nanometer sized silica sols with high surface area.
Does silica help hair growth?
Silica doesn’t promote hair growth, but it does strengthen hair and prevent thinning. It does this by delivering essential nutrients to your hair follicles. As a bonus, it can also benefit your skin and nails.
What is silica good for in 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.
