Allantoin pure product is a kind of odorless, non-irritating, non-allergenic white crystal, which crystallizes in water as a single prism or colorless crystalline powder. It is soluble in hot water, hot alcohol and dilute sodium hydroxide solution. It is slightly soluble in water and alcohol at room temperature, and difficult to dissolve in organic solvents such as ether and chloroform; its saturated aqueous solution (concentration of 0.6%) is slightly acidic; pH is 5.5. It is stable in aqueous solution with a pH value of 4-9. It is also stable in non-aqueous solvents and dry air; it can be decomposed by boiling in strong alkaline solutions and under sunlight exposure.

It achieves moisturizing effects by promoting the water absorption capacity of the outermost layer of skin and hair, reducing the evaporation of skin moisture, and forming a lubricating film on the skin surface to seal moisture.
Allantoin is stable in aqueous solutions with a pH value of 4-9, indicating that it can maintain its chemical properties unchanged under a certain range of acid and alkaline conditions. It is stable in non-aqueous solvents and dry air; it can be decomposed by boiling in strong alkaline solutions and exposure to sunlight.
Allantoin is generally considered to be non-toxic, non-irritating, and non-allergenic, which makes it very suitable for use in products that come into direct contact with human skin. In cosmetics, allantoin is often used as an additive to help protect and repair the skin due to its biocompatibility.
