EXCHANGING WITH THIS PUBLIC
In addition, the challenging issue is that various stakeholders in the
nanotechnology debate speak with different voices — for different
reasons — which ultimately leads to confusion within the Public.
The Public does not have the expert knowledge required to
evaluate the different points of view.
Up-to-date, validated, relevant scientific information made
accessible to the Public by credible sources is urgently needed.
Balanced and common sense dialogue
between the various stakeholders is crucial
for informed decision making by the Public
CASE STUDY : NANOTECHNOLOGY IN COSMETICS
The debate on nanos in cosmetics is a good case study of how
misunderstandings and misperceptions can obscure reality as to both
the nature of the products and the nature of the risks. Reality is
actually much more simple and reassuring…
Firstly, the types of products developed on the nanometric scale in
cosmetology are different from nanomaterials used in other industrial
sectors.
Secondly, they differ by their form and their molecular structure,
their mode of use and the way they interact with the environment. In
essence, they are nanoemulsions and nanopigments.

NANOEMULSIONS, LIPOSOMES & NANOCAPSULES
Nanoemulsions are found widespread in nature, such as milk.
In cosmetics, they are in fact macroscopic preparations containing
oil and water droplets reduced to nanometric size to increase the
content of nutritious oils while preserving the transparency and the
lightness of the formulas.
Sometimes fragile active ingredients, like vitamins, are protected
from air inside nanometre sized vesicles called nanocapsules or
liposome’s that release the ingredient upon contact with the skin at
the time of application.
Nanoemulsions therefore do not cross the skin barrier.
Public health agencies worldwide acknowledge their innocuity.
