An environmental lobby group is warning some cosmetic products currently on sale contain potentially harmful ingredients.
The Sustainability Council says products with so-called nanoparticles have been removed from stores in Australia and Europe, but New Zealand has been caught snoozing over regulation for nanotechnology.
Its concerns are highlighted in a report due to be issued on Monday.
The council says these cosmetics have had minimum risk assessment and wants the products withdrawn from sale until further research is conducted.
However, the Cosmetics, Toiletry & Fragrance Association says it has no concerns about the particles.
Executive director Garth Wyllie says it will not identify nanoparticles on ingredient labels unless Europe does, because most of the products are made there.
