Allantoin

Allantoin is a chemical compound with the formula C₄H₆N₄O₃. It is a diureide of glyoxylic acid. Allantoin is a major metabolic intermediate in most organisms including animals, plants, and bacteria. It is produced from uric acid, which itself is a degradation product of nucleic acids, by the action of the enzyme uricase.

Properties

Allantoin is a white, odorless, crystalline powder that is soluble in water and can dissolve in certain alcohols. Its solubility in water and its non-toxic nature make it an ideal compound for various medical and cosmetic applications. Allantoin has several properties that contribute to its effectiveness, including moisturizing and keratolytic (ability to cause keratin to soften), which makes it useful in the treatment of skin conditions such as eczema, psoriasis, and acne.

Uses
