Summarize

Allantoin is an imidazole heterocyclic compound, a derivative of uric acid, which is a component of human skin. Uric acid acts as an antioxidant and reacts with free radicals to produce allantoin, which was extracted by Mocllster in 1912 from the underground stem Chemicalbook of the comhinaceae plant. Allantoin can promote cell tissue growth, metabolism, softens keratin. These properties are especially evident when allantoin is applied to ulcerated and purulent skin, so it has the ability to speed up wound healing and is a good active agent for the treatment of skin damage. Allantoin used to be called anti-irritant, which can effectively reduce the stimulation of irritants; At the same time, it is also an antioxidant, like some other water-soluble vitamins, its ability to collect free radicals is similar to vitamin CChemicalbook, so it can enhance the antioxidant capacity of cells. Therefore, the United States Food and Drug Administration FDA listed it as the first class of highly effective active component skin care agent, which is non-toxic, non-irritating, and no allergic reaction.

Chemical property

Pure product is a non-toxic, tasteless, non-irritating, non-allergic white crystal, crystallized in water as a single prism or colorless crystalline powder. Melting point: 226-240℃. Soluble in hot water, hot alcohol and dilute sodium hydroxide solution. Slightly soluble in ambient water and alcohol, insoluble in organic solvents such as ethyl Chemicalbook ether and chloroform; Its saturated aqueous solution (concentration 0.6%) is slightly acidic. The PH is 5.5. Stable in aqueous solution with PH 4-9. Stable in non-aqueous solvents and dry air; It can be decomposed by boiling in a strong alkaline solution and exposure to sunlight.

Colorless crystalline powder. Melting point 238-240℃ (decomposition). Soluble in hot water, hot alcohol and dilute sodium hydroxide solution, slightly soluble in water and alcohol, almost insoluble in Chemicalbook ether and chloroform. Odorless, tasteless. Stable in dry air, it is destroyed in water boiling for a long time or in strong alkali. A saturated aqueous solution has a pH of 5.5.

Purpose

Allantoin is an important fine chemical product, widely used in medicine, light industry, agriculture, daily chemical, biological engineering and other aspects: 1, in medicine: allantoin has the ability to promote cell growth, accelerate wound healing, soften keratin and other physiological functions, is a good healing agent for skin wounds and anti-ulcer agents. It can be used to relieve and treat dry skin, squamous skin Chemicalbook disease, skin ulcer, digestive tract ulcer and inflammation, and has good effect on osteomyelitis, diabetes, cirrhosis and acne. 2, in cosmetics: Because allantoin is a kind of amphoteric compound, can combine with a variety of substances to form double salt, with light avoidance, sterilization, antisepsis, pain relief, antioxidant effects, can make the skin keep moisture, moisturizing and soft, is a beauty salon and other cosmetics special additives.

Allantoin has the effect of promoting skin cell growth and rapid wound healing. Used as an anti-ulcer drug, mixed with dried aluminum hydroxide gel, for digestive tract ulcers and inflammation. This product can also soften keratin, so that the skin to keep moisture, moisture and soft, is a special additive for cosmetics. Allantoic acid and its derivatives are also quality improver and additive for many daily chemical products. Allantoin protein can be formulated as a scalp preparation for anti-irritation, anti-dandruff, cleansing Chemicalbook and wound healing, which can make hair soft, shiny and elastic. The product is a kind of amphoteric compound, can combine a variety of substances in the form of double salt, with light avoidance, sterilization, anti-corrosion, pain relief, deodorization, antioxidant effect, so it is a daily chemical products, beauty cosmetics such as freckle cream, acne liquid, shampoo, soap, toothpaste, shaving detergent, astringent, anti-sweat deodorant detergent and other additives. Allantoin is also a biochemical agent. As an effective biomarker of oxidative stress response; For the synthesis of Mannich base as an antimicrobial agent; For the synthesis of sulfochlorobenzlurea analogues as antineoplastic agents; Used as a plant growth regulator. Purine metabolites via the uric acid pathway. Uric acid can also react with free radicals to form allantoin, so allantoin can be used as an effective biomarker of oxidative stress response.
