Product Description
What Is Allantoin?
Mammal urine and plants like comfrey both naturally contain the chemical allantoin. Its calming, restorative, and moisturizing qualities make it a common ingredient in pharmaceutical and cosmetic goods. It helps stimulate cell regeneration, making it beneficial for treating dry, chapped, or irritated skin.
Preparation:
Allantoin can be synthesized by the oxidation of uric acid, which involves reacting uric acid with an oxidizing agent like potassium permanganate or hydrogen peroxide. Crystallization is subsequently used to purify the resultant chemical. Additionally, allantoin can be extracted from plants such as comfrey, which contains allantoin naturally, though synthetic production is more common for commercial purposes.
