Colloidal silicon dioxide, attaching hydroxyl groups to itself, forms a complex structure. It attracts allergens, microorganisms, bacteria, poisons, harmful products decay, then takes them out with him.
When using colloidal silicon dioxide, digestion is not disturbed, and the normal flora of the gastrointestinal tract is preserved. During administration, the substance is not broken down, not absorbed, and leaves the body unchanged naturally.
Silicon dioxide is a crystalline, colorless substance and is the most stable silicon compound. It makes up 87 percent of the mass of the lithosphere.
- The better known water-insoluble crystalline form of silicon dioxide is quartz or glass, its melting point is 1610°C.

Obtaining crystalline silicon dioxide is possible:
- affecting Na silicate with acids HCl, H2SO4, CO2
- coagulating colloidal silica with NH4, Na+, F- ions
- by hydrolyzing SiF4, SiCl4, (C2H5O)4Si, (NH4)2SiF6 with water or aqueous ammonia solution.
- placing at a temperature of 300-420 ° C in an alkaline autoclave solution high pressure(35-120 MPa).
It is possible to obtain an amorphous form of silicon dioxide:
- calcining rice husks, grinding fused quartz sand.
- burning SiCl4 vapors in a mixture of H2 and O2 by chemical deposition
- oxidizing and hydrolyzing vapors of Si esters (pyrogenic silica), SiF4 (fluosil).
Pyrogenic silicon dioxide (colloidal silicon dioxide) is produced by reacting gaseous silicon tetrachloride with water vapor at high temperatures.
Silica has various polymorphic modifications due to the presence of strong single bonds between atoms (table). Their transformations are associated with a change in volume or shape through a slight displacement or rotation of the tetrahedra.
The most commonly used form of silica is α-quartz (due to its elevated temperature form).
Properties of most forms of silicon dioxide:
- insolubility of the element in the vast majority of organic solvents,
- formation of hydrofluorosilicic acid during the reaction with hydrofluoric acid,
- transparency of quartz for ultraviolet and infrared radiation,
- endowing silica with optical activity with piezoelectric characteristics due to the chiral structure of α-quartz,
- interaction with aqueous solutions of alkalis and heating of a mixture of powdered silica creates silicates, fluorosilicates, and sodium silicate.
The list of additives that are used in the production of food, pharmaceuticals and cosmetics can take up more than one page. The average person has absolutely no idea about such chemicals, their characteristics and effects on the body. However, when you encounter one of these elements in the list of components, it is better to inquire about its features, taking care of your health. Silicon dioxide is considered to be one of the most common additives. So let's talk about silicon dioxide, consider its use in medicine and cosmetics, as well as its properties on www..
Why silicon dioxide is valued (properties)
Silicon dioxide is a substance that consists of colorless crystals characterized by a high degree of strength, hardness and refractoriness. This substance is resistant to acids, in addition, it is not able to interact with water. If the reaction temperature increases, this element reacts with alkalis, gains the ability to dissolve in hydrofluoric acid, and also becomes an excellent dielectric.
Silicon dioxide in medicine
In medicine, colloidal silicon dioxide is usually used, which is a loose powder of white or white-blue color. This substance is odorless, and when shaken with water it forms a suspension. This form of silicon dioxide is used as an enterosorbent; in addition, it is used externally for the treatment of purulent-inflammatory lesions of soft tissues, for example, purulent wounds, phlegmon, abscess, mastitis, etc.
After entering water, colloidal silicon dioxide is able to attach hydroxyl groups to itself, forming a rather complex spatial structure. The main feature of the resulting structure is that the sorption of particles of toxins, allergens, microorganisms and aggressive metabolic products occurs on the surface of the particles, in those places where silicon dioxide binds to hydroxyl groups. An aqueous suspension contains many such particles; accordingly, they have a significant total sorption area. Sorption takes place on the surface, due to which such enterosorbent successfully fixes aggressive substances and removes them along with it. Moreover, its effect also extends to substances with a large molecular weight, which include allergens, due to which colloidal silicon dioxide is actively used in the treatment of allergies.
Colloidal silicon dioxide is capable of binding and eliminating from the body endogenous as well as exogenous aggressive substances of various natures. It helps cope with pathogenic bacteria, bacterial toxins, antigens, allergens, medications and poisons. This substance also exhibits activity against salts of heavy metals, radionuclides and some metabolic products represented by excess bilirubin, urea, as well as cholesterol, alcohol breakdown products and metabolites responsible for the formation of endogenous toxicosis. When using colloidal silicon dioxide, the normal components of the gastrointestinal flora are preserved and digestion is not disturbed. The drug is not broken down in any way in the digestive tract and is not absorbed, leaving the body naturally in a completely unchanged form.
Silicon dioxide in cosmetics
This substance occupies far from the last place in the production of cosmetics. This element is often used to create toothpastes. So many people believe that whitening pastes are far from beneficial for teeth, as they can damage the integrity of tooth enamel. However, if their main component is silicon dioxide, this paste will not harm the teeth. Thus, silica is a completely safe and at the same time effective bleaching abrasive.
In addition, this element is often used as a base and additional components when creating a wide variety of cosmetics. It has an effective mattifying effect, which makes it a real find for girls with oily and shiny skin. It is added to lotions, creams and powders. This supplement also smoothes out skin unevenness quite well, eliminating existing wrinkles. Silicon dioxide is often added to cosmetics intended for various types skin and for different ages.
Another useful cosmetic property of such a substance is the ability to remove already dead skin cells. Thanks to this quality, the skin renews itself much faster and begins to shine with health and beauty.
Thus, the effect of silicon dioxide on the body is undeniable. This is a fairly useful supplement, which at the same time is not able to be absorbed into the body’s tissues.

Description
Colloidal silicon "SILICA" - maximum bioavailability!
Colloidal silicon SILICA will breathe new life into a comprehensive approach to maintaining health, supporting systemic detoxification and cellular regeneration of the body. To maintain the immune system and improve the condition of bones, joints, skin, hair, nails and blood vessels, a person needs to additionally consume at least 50–75 mg of silicon (2–3 ml of colloidal silicon SILICA) daily.
For many years, practicing European doctors have achieved the best results by working with silicon in colloidal form.
Advantages of colloidal silicon "SILICA":
Maximum absorption by the body compared to other forms and types of silicon (including plant silicon);
Stable colloidal state without precipitation;
No unwanted side effects;
Maximum content of active substance compared to similar products (tens of times);
Colloidal silicon SILICA is what nature itself offers us; it is difficult to beat in purity and quality.
A 100 ml bottle contains 5 grams of silicon dioxide.
Colloids are the physical and chemical basis of life. Colloids are solutions in which very small, solid particles float. It appears that they can defy gravity, and this also happens. All liquids in living systems are colloids if the system is healthy. Thus, red blood cells “float” throughout our body and, as a result, form a huge internal surface. If we get sick, the blood cells agglutinate, which is confirmed in studies.
The language our body understands is colloids. The smallest substances dissolved in an aqueous solution are what nature offers us. The colloidal state is a state of a living organism and a guarantor of health.
Silicon is a vital microelement. It supports every cell of the body in its functions, strengthens the skin, hair and nails, strengthens the immune system and our bones. The intake of silicon in a colloidal state into our body gives the effect of optimal absorption.
