Allantoin Molecular formula: C4H6O3N4 CAS No.: 97-59-6 Molecular weight: 158.12 Appearance: White crystalline powder, odorless and tasteless Production method: It is synthesized using glyoxalic acid and urea as raw materials Quality specifications: (USP23) Specification name Specification Content (%): ≥98.0 Loss on drying (%): ≤1.0 Residue on ignition (%): ≤0.1 Heavy metals (as Pb): ≤10ppm Melting point: 226–240°C Solubility: Soluble in water; slightly soluble in glycerol and propylene glycol; very slightly soluble in ethanol and methanol; practically insoluble in mineral oil, ether, and chloroform Physical and chemical properties: Pure allantoin is a non-toxic, odorless, non-irritating, and non-allergenic white crystal that forms monoclinic prisms or colorless crystalline powder when crystallized in water. It is soluble in hot water, hot alcohol, and dilute sodium hydroxide solution. Slightly soluble in water and alcohol at room temperature; insoluble in organic solvents such as ether and chloroform ; Its saturated aqueous solution (at a concentration of 0.6%) is slightly acidic ; The pH is 5.5. Stable in aqueous solutions with a pH of 4-9. Stable in non-aqueous solvents and dry air as well ; It can be decomposed by boiling in strongly alkaline solutions and exposure to sunlight.   Uses: 1. In the pharmaceutical field, allantoin has physiological functions such as promoting cell growth, accelerating wound healing, and softening keratin; it is an effective agent for healing skin injuries and for treating ulcers. It can be used to alleviate and treat skin dryness, scaly skin conditions, skin ulcers, gastrointestinal ulcers, and inflammation; it also shows good efficacy in treating osteomyelitis, diabetes, liver cirrhosis, and acne.   2. In the field of cosmetics: Since allantoin is an amphoteric compound that can combine with various substances to form complex salts, it has properties such as light protection, antibacterial and preservative effects, pain relief, and antioxidant action. It helps to retain moisture in the skin, making it softer and more hydrated. Therefore, it is an effective additive in cosmetics for beauty and hair care, and is widely used as an additive in products such as freckle creams, acne treatments, shampoos, soaps, toothpaste, facial cleansers, hair conditioners, astringents, and antiperspirant deodorants.   3. In agriculture: Allantoin is an excellent plant growth regulator that stimulates plant growth; it yields significant increases in yield for crops such as wheat, citrus, rice, vegetables, and soybeans, and it also helps to improve fruit set and promote early maturity.
