Activated charcoal has become increasingly popular in oral care products, celebrated for its supposed ability to detoxify, whiten teeth, and improve overall oral hygiene. Derived from carbon-rich materials, activated charcoal is processed to create a highly porous substance with a vast surface area, which enhances its adsorptive properties. This ability to bind to various compounds makes it effective in numerous applications, including in the dental field for managing plaque and promoting oral health.
Activated charcoal is carbon that has been treated to increase its adsorptive capacity. It is made by heating carbon-rich materials—such as wood, coconut shells, or peat—in the presence of a gas that causes the material to develop a porous structure. This process, known as activation, creates a large surface area that allows the charcoal to adsorb substances, toxins, and impurities.
Composition
The main active ingredient in activated charcoal is carbon, but it also contains small amounts of other elements like hydrogen and oxygen. The porous structure is what allows activated charcoal to bind with various compounds, making it useful for a range of applications, including medical uses (like poison treatment) and personal care products.
