The European Union has passed laws making it mandatory for all products containing nanoparticles - which are , times smaller than the width of a human hair - to say so on the label. While a NSW parliamentary inquiry has recommended that labelling requirements for cosmetics include the identification of nano-scale materials, in Australia there is still no requirement for manufacturers to label their nanotechnology products.
The study, commissioned by Friends of the Earth and conducted by the Australian Microscopy and Microanalysis Research Facility, tested 10 brands, eight of which contained particles measuring less than nanometres. Products tested included foundations and concealers.
Only one brand - Christian Dior - listed the use of nanoparticles on the label, the report said. It also recommended that nano-ingredients in products should be labelled, to give people the chance to make an informed choice.
Europe has passed new laws that will require most nano-ingredients in sunscreens cosmetics to face new safety testing and mandatory labelling. Yet where substances have been approved for use as larger particles, Australian laws do not make companies test for safety before using these substances as nanoparticles, nor to label nano-ingredients.
Failing to label nano-ingredients denies consumers the capacity to make an informed choice The nanoparticles found are used to diffuse light disguising wrinkles , provide sun protection or for improved colour. Large cosmetic manufacturers depend on micronized and sometimes, nanoparticle form ingredients to achieve the finest product quality and applied finishes.
Micronized ingredients are not necessarily nanoparticles. It is important to understand the difference and find out if the brand of make-up that you wish to use contains nanoparticles.
Nanoparticles are particles that are so small, they are measured in billionths of a meter nanometers. A nanoparticle is defined as anything between nanometers in diameter.
These ultra fine particles are a boon to the cosmetic industry because they "fill" the microscopic crevices in the skin and glide over the skin smoothly. They, however, also pose a serious health risk when inhaled or absorbed into the body.
