2Products containing engineered nanoparticles are
being sold now
- Nanoparticles are in hundreds of products on the
market now personal care, textiles, coatings
etc. - Growing evidence shows that nanomaterials can be
toxic to humans - Products are sold without labels informing
consumers of the presence of these untested or
only partially tested ingredients - They have not been proven safe for consumers,
workers or the environment
3Recommendations of the UKs Royal Society
- Ingredients in the form of nanoparticles should
undergo a full safety assessment by the relevant
scientific advisory body before they are
permitted for use in products - Factories and research laboratories should treat
nanomaterials as if they were hazardous - Their release into the environment should be
avoided as far as possible
4Nano products are already on the market
5Areas in which nano products are on the market
6Areas in which nano products are on the market
7Consumers are not very concerned, so far
- Eurobarometer 224
- Which science and technology developments are you
most interested in? (multiple answers possible)
8Small Ingredients, Big Risks The example of
sunscreens and cosmetics
- At least 116 cosmetics, sunscreens, and personal
care products contain nanomaterials, despite
complete absence of independent safety assessment
and regulation - The survey represents only a small sample of the
cosmetics and personal care products containing
engineered nanoparticles
9Is there a cause for concern?
- The intimate use of cosmetics and personal care
products poses a risk of exposure because the
products are used daily and directly on the skin.
They may be inhaled and are often ingested. - Nanoparticles have a greater risk of toxicity,
are more readily taken up by the human body and
are able to cross biological membranes (e.g.
brain barrier, placenta) and access cells,
tissues and organs
10Nanoparticles can be potentially beneficial for
the environment
- Less ressources needed, due to more energy
efficient and lighter materials - Less environmentally harmful by-products
(emissions of carbon dioxide or other harmful
substances - New cleaning methods for toxins in soil and water
- More efficiency in power production
11...but they can also harm human health and the
environment
- Nanoparticles of titanium dioxide and zinc oxide
have been shown to be photoactive, producing free
radicals and causing DNA damage to skin cells
when exposed to UV light. - Seven face creams listed in the report contain
carbon spheres called fullerenes, which have
been found to cause brain damage in fish. Two of
those creams (Zelens and Dr Brandt) are currently
sold on the EU market.
12Nanoparticles may enter and move freely inside
human body
- While the jury is still out on whether
nanomaterials can enter intact skin, studies show
that broken skin is an ineffective barrier the
presence of acne, eczema, shaving wounds or
sunburn enables the uptake of nanoparticles - Many cosmetics and personal care products contain
ingredients that act as penetration enhancers,
which may even increase skin uptake and entry
into the blood stream.
13More information is needed
- Cosmetics companies need to be more transparent
about their safety testing - We dont know how much safety research the
sunscreen and cosmetics manufacturers have
conducted before placing the products on the
market. - Studies need to be peer-reviewed and publicly
accessible - We need a regulatory oversight to ensure safety
testing is independent and comprehensive
14FoEs Recommendations
- Nanomaterials and products must be subject to
health and environmental impact assessment, prior
to commercial production and/or environmental
release - Nanoparticles must be assessed as new substances
- Consumers have the right to know about
nanoparticles in products they buy - We need a moratorium on the release of new
products and the withdrawal of all existing
products where nanoparticles get in direct
contact with the consumers - Precautionary principle should be the basis for
dealing with nanoparticles
