Silica gel is a granular and porous silica hydrate. It is prepared by washing and drying sodium silicate with acid. The main component is silica, which has stable chemical properties and does not burn. Although the name is "glue", it is actually a solid, transparent or milky white. It has an open porous structure, strong adsorption, and can adsorb a variety of substances.
Due to its strong adsorption, it can quickly and effectively absorb the moisture in the sealed package, the chemical properties are stable, non-toxic and harmless, silica gel has been widely used in drug purification, DNA separation, food drying, high-precision electronics, advanced cosmetics, sewage purification , Beer purification, advanced coatings and resin production or preservation, etc.
Silica gel is an amorphous substance. It is insoluble in water and any solvents, non-toxic and odorless, chemically stable, and does not react with any substance except strong alkali and hydrofluoric acid. Various types of silica gel have different microporous structures due to different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many characteristics that are difficult to replace by other similar materials: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength.
Color-changing silica gel: Soak the silicic acid gel in a solution of cobalt chloride (CoCl2) or ammonium chlorocobaltate ((NH4)2CoCl4), and then activate it by drying to obtain a color-changing silica gel, which can be used to indicate the degree of water absorption of the silica gel. This is because the anhydrous cobalt chloride (CoCl2) is blue, and the cobalt chloride hexahydrate (CoCl2•6H2O) is red.
The main component of silica gel is silica, which is chemically stable and non-toxic.
Silica gel has a strong adsorption capacity and can have a drying effect on human skin. If the silica gel gets into your eyes, you need to rinse with plenty of water and seek medical treatment as soon as possible.
Blue silica gel is poisonous because it contains a small amount of cobalt chloride. Avoid contact with food and inhalation. If a poisoning event occurs, you should seek medical treatment immediately.
Why do silicones in scar care products contain silicone?
Because the skin care products with silicone ingredients can form a protective film on the scars and form a slight pressure on the local skin, it can prevent the scar tissue from accumulating outwards. The protective film formed by ghosts can also reduce local water evaporation and promote wound healing. , So as to reduce scar tissue growth and reduce scars.
Silicones are truly cosmetic chemicals and are used in personal care applications. They smooth creams and lotions. In shampoos, silicones make hair softer and easier to comb.
