Every week, dedicated European portals (Safety Gate for the European Union, Safety Database for the United Kingdom) list the non-compliant and/or dangerous products detected on the market by the control authorities. Here are the cosmetic products that are subject to a recall or a marketing ban this week: a nail polish and a tooth whitening kit whose concentration of particular ingredients is too high.

Teeth whitening kit

Batch number: 13733
• Country of origin: Brazil

Risk type: chemical
The product contains too much sodium fluoride (measured value up to 2% by weight).
At high concentrations sodium fluoride can cause spots in tooth enamel (dental fluorosis). In moderate to severe fluorosis, teeth are also weakened and suffer permanent physical damage. Chronic over-absorption of sodium fluoride can cause hardening of bones, calcification of ligaments, and buildup on teeth. Excessive intake of sodium fluoride can also be toxic if swallowed, causes serious eye irritation and causes skin irritation.
The product does not comply with the Cosmetic Products Regulation.
Measures ordered by public authorities: withdrawal of the product from the market
