Silica, SiO2, is composed of Silicone and Oxygen. It has been known since ancient times, is found in sand, and is a major component of glass. Silica is a chemical compound, also called silicon dioxide.
What is silica composed of?
Silica is another name for the chemical compound composed of silicon and oxygen with the chemical formula SiO2, or silicon dioxide. There are many forms of silica. All silica forms are identical in chemical composition, but have different atom arrangements.
Where does silica come from?
The most common form of crystalline silica is quartz, which is found in sand, gravel, clay, granite, diatomaceous earth, and many other forms of rock. Non-crystalline silica is found in glass, silicon carbide, and silicone. These materials are much less hazardous to the lungs.
Is silica harmful to humans?
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 is silica used in?
Materials like sand, stone, concrete, and mortar contain crystalline silica. It is also used to make products such as glass, pottery, ceramics, bricks, and artificial stone.
How many types of silica are there?
Silica exists in nine different crystalline forms or polymorphs with the three main forms being quartz, which is by far the most common, tridymite and cristobalite. It also occurs in a number of cryptocrystalline forms.
What is silica in food?
Silicon dioxide, also known as synthetic amorphous silica (SAS), is used by food manufacturers as an anti-caking agent in spices or creamers, to ensure fine flowing powders or to absorb water. It is made up of aggregated nano-sized primary particles which are usually greater than 100 nm.
Do humans need silica?
Why do you need silica? 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.
Is silica safe to eat?
According to the United States Department of Labor, about 2.3 million people in the U.S. are exposed to silica at work. As long as you aren’t inhaling silica in its crystalline form, it appears to be safe to consume at the levels set out by the FDA.
Where is silica mostly found?
Silica is often found in nature as sand (non coastal), usually in the form of quartz. The most common form of manufactured silica is glass. Silica, is a natural compound that has a crystal characteristic and can be found in beach sand.
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.
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.
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 homeopathic silica used for?
Highly diluted solutions of silica are widely used in homeopathic medicine to treat lesions such as chronic wounds, ulcers, and abscesses.
Why is silica in toothpaste?
The primary benefit of hydrated silica in toothpaste is its abrasiveness. Stains often settle on our enamel, the outermost layer of our teeth. But whitening toothpaste with abrasive ingredients, such as hydrated silica, scrub the stains from the surface of your teeth.
What is the most toxic form of silica?
Animal studies suggest that tridymite and cristobalite are the most toxic forms of crystalline silica, followed closely by quartz (Seaton 1984).
Is silica good for health?
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.
Is silica a natural?
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’s found naturally in water, plants, animals, and the earth. The earth’s crust is 59 percent silica.

Silicon deficiency may be detected when the deterioration of the skin, hair and nails occurs. 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;.
Does silica tighten skin?
When collagen is damaged, silica helps rebuild it and keep tissues connected. This provides a lifting and tightening effect on the skin all over your body. Silica may also be able to help the skin retain water, which helps it stay hydrated and healthy, and give it more “bounce” or elasticity.
Is it better to take collagen or silica?
The big difference? Collagen provides the readily available base for an instant collagen ‘top up’ while silica helps to make collagen so will take longer for any noticeable effect.
Does silica build collagen?
Silica is required for the production of collagen, and as you age, both collagen and silica levels begin to decline. Silica supports connective tissue health including bones, hair, skin elasticity and structure, and nails.
