I came across this article on "Keep Nanotechnology Out of Organic!".

 Nanotechnology can be found in some of the cosmetics products here. It claimed to be more effective as it is able to penetrate into your system better due to the  tiny nano size of the molecues. well,  it is true that it is able to penetrate better but the question is "Are the things penetrating through your skin SAFE for you?" Stop for a moment and think about it before falling for the promise that these wonderful nano products made.

An excerpt of the article on Keep Nanotechnology Out of Organic:

A major reason why consumers shop for products that are certified organic is to avoid hazardous and unlabeled Genetically Modified Organisms (GMOs), toxic chemicals, and now the most recent, and likely most dangerous hi-tech poison of them all - nanotechnology. Nanotechnology is now a multi-billion dollar Frankenstein monster industry churning out a vast menu of untested and unlabeled products containing tiny nanoparticles including non-organic vitamin supplements, food packaging, processed food, cosmetics, and sunscreens.

The United States Department of Agriculture's National Organic Standards Board (NOSB) has been debating an official ban on nanotechnology in organic. When it meets November 3-5, 2009 in Washington, D.C., the NOSB will consider a recommendation supported by the the OCA and the organic community that would "prohibit nanotechnology in organic production, processing, and packaging."

Nanotechnology is inherently dangerous. Mounting scientific evidence indicates that nanomaterials produce dangerous "free radicals" which can destroy or mutate DNA and can cause damage to the liver and kidneys. Nanotech particles not only injure and kill lab animals - they can kill you as well.

Every day, new evidence of the dangers of nanotechnology emerges:

Workplace nanoparticle exposure was linked to seven cases of serious and progressive lung disease in China including two patient deaths.
Nanoparticles present in a chemical found in sunscreens - titanium dioxide - are being examined as possibly causing Alzheimer's and Parkinson's diseases.

 Bottom line:  Keep away from products using nanotechnology for now till further concrete scientific testing are proven.
