Nano-technologies refer to materials on an incredibly small scale - one nanometre is a millionth of a millimetre, so imagine a mouse in comparison to earth. They are now used in European industries from food, cosmetics, textiles to electrical appliances and medicines. While it can offer benefits, nano-materials have not been subjected to proper safety assessments. This highly risky approach was campaigned against by BEUC. As consumers should be well informed on such issues, we advocated for transparent labelling of nano-products we come in close contact with such as food and cosmetics.
