Champ d’application

This standard applies specifically to sodium monofluorophosphate utilized in the toothpaste industry. It covers the product when used as an anti-caries agent, desensitizing additive, bactericide, and preservative. Manufacturers supplying this chemical to Chinese toothpaste producers must comply with this standard. It also references GB/T 191-2008 for packaging pictorial marks.

Exigences techniques

Chapters 4 and 7 of this standard are mandatory. The standard specifies that the product must appear as a white powder. It establishes strict limits for various fluorine contents, including combined fluorine, free fluorine, and total fluorine. Furthermore, it sets maximum allowable limits for heavy metals, specifically arsenic (As) and lead (Pb). Additional parameters include water insoluble matter, pH value, and loss on drying. Compliance with these chemical and physical parameters is strictly enforced for market access.

Méthodes d’essai

The standard outlines specific analytical methods to verify compliance. Free and total fluorine are determined using an ion-selective electrode method. Lead content is measured via atomic absorption spectrophotometry using a graphite furnace. Heavy metals and arsenic are evaluated using colorimetric methods referenced in GB/T 610-2008. Physical properties like pH value and loss on drying are tested using standard laboratory equipment. Accurate testing according to these procedures is essential for certification.
