This substance in a wonderful way combines the properties of a stabilizer and emulsifier. In nature, its analogue also exists - sulfuric acid, calcium salt. In the natural environment, calcium sulfate is formed from dehydrated gypsum deposits, is contained in gypsum and selenite, like dihydrate. The hardness of tap water is directly related to the concentration of potassium sulfate in it.

On an industrial scale, such an additive is obtained by fusing potassium sulfate with calcium chloride. As a result of this reaction, a precipitate forms, which is calcium sulfate.

In appearance, this substance most closely resembles a white or slightly yellowish crystalline powder of a bitter-salty taste and odorless. Its chemical composition includes calcium sulfate and various impurities: fluorides, selenium and others. The molecular formula of a substance can be denoted as: CaSO4.

This food emulsifier is practically insoluble in water and absolutely insoluble in ethanol. However, it has good solubility in glycerol, acidic medium and ammonium salts.

This food supplement is a moisture-absorbing substance. It is capable of absorbing up to seven percent of the total water. Melts at very high temperatures, hygroscopic.
