NOVELTY - Preparing toothpaste containing bioactive glass involves dissolving lauryl amine in mixed solution of ethanol-deionized water, adding ethyl orthosilicate, uniformly dispersing triethyl phosphate and calcium nitrate tetrahydrate, drying precipitate after centrifugal treatment, heating to obtain bioactive glass powder; adding moisturizer, bioactive glass powder, slow release agent, preservative, fluoride and antibacterial friction agent into colloidal substance, mixing uniformly, adding foaming agent, stirring and homogenizing to obtain paste; vacuum degassing and standing to obtain product. USE - Method for preparing toothpaste containing bioactive glass used as cleaning and protecting product for promoting re-formation of enamel. ADVANTAGE - The method enables to provide good dispersibility, without agglomeration in toothpaste system.
