Vitamin D is a fat-soluble vitamin, which is also regarded as a hormone precursor that acts on calcium and phosphorus metabolism, and is closely related to sunlight, so it is also called the "sunshine vitamin". Vitamin D3 (cholecalciferol) is mainly synthesized by the body itself, the human skin contains a kind of cholesterol, after exposure to the sun, it becomes vitamin D3.
Creatine is a nitrogenous compound stored in the muscle of mammals and fish, 95% of which is stored in skeletal muscle (making animal meat an excellent dietary source), but a small number (half a kilogram of meat can only provide 1 grams of creatine).
Creatine monohydrate, as a form of creatine, is easily absorbed by the body and helps improve physical performance during sustained short, intense workouts.
Ciprofloxacin is a fluoroquinolone (flor-o-KWIN-o-lone) antibiotic, it is used to treat different types of bacterial infections. It is also used to treat people who have been exposed to anthrax or certain types of plague. Ciprofloxacin extended-release is only approved for use in adults.
Sebacic acid is widely used in the preparation of sebacic acid esters, such as dibutyl sebacate, dioctyl sebacate, diisooctyl sebacate. These esters can be used as plasticizers for plastics and cold-resistant rubber, as well as for polyamide, polyurethane, alkyd resin, synthetic lubricating oil, lubricating oil additives, spices, coatings, cosmetics, etc.
Pregelatinised starch is modified starch, starch is partially or completely broken by chemical or mechanical methods. It is often used as a binder, diluent and disintegrator in tablets. The pre-gummed starch has self-lubricating effect, and magnesium stearate should be added as lubricant when used with other auxiliary materials.
Metronidazole, an organic compound with the chemical formula C6H9N3O3, is primarily used as an antibiotic and antigenic insecticide to treat or prevent systemic or local infections caused by anaerobic bacteria
Fumed silicon dioxide (fumed white carbon black) is one of the most important high-tech ultrafine inorganic new materials. Due to its small particle size, it has a large specific surface area, strong surface adsorption force, large surface energy, high chemical purity, good dispersion, thermal resistance, resistance and other aspects of its specific properties. It has unique characteristics in many disciplines and fields and plays an irreplaceable role.
Polyvinyl pyrrolidone (PVP) is a non-ionic polymer that is the most distinctive, best-studied and most widely studied fine chemical among N-vinyl amide polymers.
Pearlescent paste is a daily chemical raw material mainly composed of glycol stearate, alkyl ether sulfate and alkanolamide, which is suitable for imparting pearlescent luster to shampoo and other liquid products.
