Why are diatoms used in toothpaste?

Diatomites are white, soft, and porous particles that are part of the plant kingdom algae. When a diatom dies, its shell is composed of silica and organic compounds.

Because of its mildly abrasive qualities, this silica from diatoms is used in tooth pastes and powders.

Diatoms are used in toothpaste as abrasives to help remove plaque and surface stains from teeth. Their microscopic silica shells provide gentle scrubbing action without damaging tooth enamel. Additionally, diatoms are natural and biodegradable, making them environmentally friendly alternatives to synthetic abrasives.

Diatoms are used in toothpaste primarily because of their abrasive properties. The silica shells of diatoms are very hard and have a naturally abrasive texture, which helps to scrub away plaque and stains from the surface of teeth without causing significant damage to the enamel. Additionally, diatoms are a natural, biodegradable alternative to synthetic abrasives often used in toothpaste formulations, making them an environmentally friendly option.
