Allantoin

Allantoin is an imidazole heterocyclic compound, a derivative of uric acid, and a natural component of human skin. Uric acid, as an antioxidant, reacts with free radicals to produce allantoin. In 1912, Mocllster extracted allantoin from the underground stem of the Boraginaceae plant, Chemicalbook. Allantoin can promote cell tissue growth, metabolism, and soften stratum corneum protein. When allantoin is applied to ulcerated and suppurated skin, these properties are particularly obvious, so it has the effect of accelerating wound healing and is a good active agent for treating skin damage.

1. Emollient and repairing effect Allantoin has a good emollient effect, especially for chapped and rough skin, it can restore its smoothness and moisture. At the same time, it can enhance the water absorption capacity of the outermost layer of skin and hair, improve the hydrophilicity of keratin molecules, repair the damaged stratum corneum, and restore its natural water absorption capacity.

2. Moisturizing effect Allantoin can promote the water absorption capacity of the outermost layer of skin and hair and reduce the evaporation of skin moisture. At the same time, it can also form a lubricating film on the surface of the skin to seal the moisture, thereby achieving the effect of skin moisturizing.

3. Softening keratin effect Allantoin has a unique keratin-dissolving property, so it has the effect of softening keratin. While stripping off metabolic waste keratin, it fills the intercellular space with water to make the skin moist and shiny.

4. Anti-inflammatory and antioxidant effects. Since allantoin is an amphoteric compound, it can combine with various substances to form complex salts. It has light-shielding, bactericidal, antiseptic, analgesic and antioxidant effects. It is widely used as an additive in freckle cream, acne liquid, shampoo, soap, toothpaste, shaving lotion, hair conditioner, astringent, antiperspirant and deodorant lotion, etc.
