Hydrated Silica
What is Hydrated Silica?
Hydrated Silica is a form of silicon dioxide where water has been chemically bound to the silica. It is a fine, white, odorless powder that is often used in various personal care products.
In toothpaste, hydrated silica acts as a mild abrasive to help clean and polish the teeth, which can contribute to whitening them without being too harsh on enamel. The health evidence suggests it is generally considered safe for use in oral care products, with no significant documented health risks.
When you see hydrated silica on a label, it typically indicates its role as an abrasive agent to enhance cleaning and whitening effects. It's important to note that it doesn't provide direct therapeutic benefits beyond its cleaning action.
