STANNOUS FLUORIDE (tin(II) fluoride): Allowed with restrictions, with limits depending on the product type (Annex III, entry 35), under Regulation (EC) No 1223/2009. Annexes of the Regulation consulted on 21 October 2026.

Who it concerns

What official classifications and rules say for each group. A classification describes the hazard of the pure substance, not the risk of a product that contains it, which depends on the dose and the exposure.

  • Pregnancy and breastfeeding

    No official classification covers reproduction, the unborn child's development or breastfeeding for this substance.

  • Babies and children

    Annex III, entry 35, sets a condition for children: “For any toothpaste with compounds containing fluorine in a concentration of 0.1 to 0.15% calculated as F unless it is already labelled as contra-indicated for children (e.g.”

  • Skin, eyes and allergies

    No official classification for sensitisation, irritation or eye damage, and no obligation to label it as an allergen.

  • Environment

    No official classification as hazardous to the aquatic environment and no assessment as an endocrine disruptor for the environment.

In plain words

What it is used for

Functions declared by manufacturers:

Antiplaque: helps protect against plaque.

Oral care: provides cosmetic effects to the oral cavity, e.g. cleansing, deodorising, protecting.

What the rules say

Allowed, with restrictions: Annex III sets a maximum concentration, the product types allowed and a warning to be printed on the packaging. Ingredient lists do not give quantities, so the concentration cannot be checked on the label; the warning can.
