GB/T 45893-2025 is the English-translated version of 口腔清洁护理用品用磷硅酸钙.

GB/T 45893-2025 is the Chinese national standard covering the bioactive powder that oral care products use to build mineral back onto tooth tissue — the amorphous calcium, phosphorus and silicon composition determined by X-ray fluorescence, the specific surface area, the pH and the whiteness, the bioactivity judged by how quickly hydroxyapatite forms when the powder meets saliva, which is what separates it from an inert abrasive, the inspection rules, the net content, and the shelf life. First edition, under the China National Light Industry Council. In force from 1 January 2026. Issued on 30 June 2025, it has been in force since 1 January 2026.

3 Terms and Definitions

The following terms and definitions apply to this document.

3.1 bioactivity

The characteristic of inducing a specific biological response at the material interface allows the material and tooth tissue to form a connection.

[Source. YY/T 1447-2016, 3.3, modified]

3.2

An amorphous silicate-based solid composed of the elements calcium, phosphorus, silicon and oxygen that is biologically active (3.1).

Note. Calcium phosphosilicate releases ions when it comes into contact with saliva, forming hydroxyapatite or carbonated hydroxyapatite. The shorter the formation time, the more complete the structure and the more biologically active it is.
