摘要

Embodiments of a method of making an oral care composition comprise providing plant material comprising silica, burning the plant material to remove organic impurities from the plant source material, removing inorganic impurities from the burnt plant material by hydrolyzing with an aqueous acid solution, separating the silica from the burnt plant material, and incorporating the separated silica into an oral care composition.
