Silica gel powder is a colloidal system with solid properties, consisting of colloidal particles that form an aggregated structure. Colloidal particles are condensates of hydrated silica gel (polysilicic acid) and are amorphous substances. In reagent column chromatography, the voids of the colloidal aggregates form a microporous structure inside the silica particles.

Calcium formate is an organic substance with the molecular formula C2H2O4Ca, used as a feed additive for all types of animals with acidifying, anti-mould and anti-bacterial effects, and industrially used in concrete, mortar additives, tanning of leather or as an antiseptic.

Trichloroisocyanuric acid, an organic compound with the chemical formula C3Cl3N3O3, is a white crystalline powder, soluble in dilute alkali, ammonia and pyridine, slightly soluble in water, aqueous solution is unstable, mainly used in biochemical research, used as a substrate for the determination of cholagogue dehydrogenase activity.

Ethyl Alcohol (Ethyl Alcohol), commonly known as alcohol, fire wine, is a kind of alcohol compounds, the chemical formula is C2H6O, the structure of the simple formula for CH3CH2OH or C2H5OH. ethanol combusts very well, it is commonly used as a fuel, solvent and disinfectant, etc., and is widely used in organic synthesis.

Sodium dodecyl sulfate, an organic compound with chemical formula C12H25SO4Na, is a white or light yellow powder, easily soluble in water, insensitive to alkali and hard water. It has decontamination, emulsification and excellent foaming power. It is a kind of anionic surfactant which is slightly toxic to human body, and its biodegradability is >90%.

Ethanol:Colorless transparent liquid. It is distilled at 78.01°C as an azeotropic mixture with water. Volatile. Can be miscible with water and organic solvents such as propanetriol, trichloromethane, benzene and ether.

Polyethylene Glycol-4000 (Macrogol 4000) is a white waxy solid flake or granular powder; slightly peculiar odor. Soluble in water or ethanol, insoluble in ether. This product is an osmotic laxative. It traps water molecules through hydrogen bonding, so that the water is retained in the colon, increasing the water content of feces and softening feces, restoring feces volume and weight to normal, and facilitating the final completion of defecation, thus improving the symptoms of constipation.

Soap granules are a natural cleanser made from plant extracts that are free of chemicals and synthetic substances. Because it is a natural ingredient, it is not prone to chemical reactions and is not harmful to health or the environment

Polymeric aluminum chloride is a water purification material, inorganic polymer coagulant, also known as polyaluminum for short, abbreviated as PAC, due to the bridging effect of hydroxide ions and polymerization of multivalent anions to produce a larger molecular weight, higher charge inorganic polymer water treatment chemicals. In form, it can be divided into solid and liquid. The solid is divided into tan, beige, golden yellow and white according to different colors, and the liquid can be presented as colorless transparent, slightly yellow, light yellow to yellowish brown. Different colors of polymeric aluminum chloride in the application and production technology also has a big difference.

Silica gel is a transparent, glassy granule usually obtained by reacting sodium silicate with sulfuric acid and undergoing a series of processes including aging and acid bubbling. Its main component is silica. As a desiccant, it has an average pore size of 2.4 nanometers and a strong affinity for water molecules. It absorbs water by physical adsorption and does not change its state after absorbing moisture. It has strong moisture absorption ability and can effectively protect food or medicine from moisture.

Soda ash, also known as sodium hydroxide or caustic soda, is a common inorganic compound.
