Executive Summary
Tooth whitening kits, borderline device/cosmetic products, sold in some EU countries as cosmetics and in others (including the UK) as medical devices, have hit the headlines. The UK's Trading Standards Institute (TSI) found hydrogen peroxide levels were higher than the legal limit in 18 out of 20 OTC and internet products tested. In one case, the legal limit was exceeded by 230 times, according to BBC News. Manufacturers and suppliers of items that failed the 0.1% limit have been told to withdraw the products from sale.
