Nanoparticles, cosmetics and sunscreens – again!

by Andrew Maynard May 3, 2012

Robin Erb has a good piece on cosmetics and safe ingredients in the Detroit Free Press this week – it tackles the very limited regulation over what goes into cosmetics, but balances this with a useful perspective on consumer choice and how this in turn can drive business decisions on what is used and how.  [...]

Are consumers risking skin cancer because of fears over nanoparticles in sunscreens?

by Andrew Maynard February 20, 2012

This has just landed in my email in box from Craig Cormick at the Department of Industry, Innovation, Science, Research and Tertiary Education in Australia, and I thought I would pass it on given the string of posts on nanoparticles in sunscreens on 2020 Science over the past few years: At Australia’s International Conference on [...]

Australian Education Union advises against using nanoparticle-based sunscreens in schools

by Andrew Maynard May 22, 2011

Last week, the Victoria branch of the Australian Education Union (AEU) passed a resolution recommending that “workplaces use only nanoparticle-free sunscreen” and that sunscreens used by members on children are selected from those “highlighted in the Safe Sunshine Guide produced by Friends of the Earth” as being nano-free.  The AEU also resolved to provide the [...]

Nano-sunscreens leave their mark

by Andrew Maynard August 19, 2010

Most manufacturers of nanomaterial-based sunscreens try to make sure that the material they use doesn’t generate harmful chemicals in the presence of sunlight.  But the paper this piece was based on suggested that some photoactive materials might be slipping through the net. Originally posted June 21 2008. Painted metal roofs are cheap, convenient, and usually [...]

The safety of nanotechnology-based sunscreens – some reflections

by Andrew Maynard July 18, 2010

A few weeks ago, I set Friends of the Earth a challenge – What is your worst case estimate of the human health risk from titanium dioxide and/or zinc oxide nanoparticles in sunscreens? The challenge came out of an article from FoE on nanomaterials and sunscreens, which I subsequently critiqued on 2020 Science.  Georgia Miller [...]

Just how risky can nanoparticles in sunscreens be? Friends of the Earth respond

by Georgia Miller June 15, 2010

Last week, I posed Friends of the Earth a challenge – “What is your worst case estimate of the human health risk from titanium dioxide and/or zinc oxide nanoparticles in sunscreens?”  Georgia Miller of FoE Australia and Ian Illuminato of FoE in the US have kindly provided a detailed response.  Rather than just keep this [...]

Just how risky could nanoparticles in sunscreens be?

by Andrew Maynard June 8, 2010

Following up from my previous post, here’s an open question to Friends of the Earth: What is your worst case estimate of the human health risk from titanium dioxide and/or zinc oxide nanoparticles in sunscreens? What I am interested in is a number – a probability of a specific human health impact being caused by [...]

Friends of the Earth come down hard on nanotechnology – are they right?

by Andrew Maynard June 8, 2010

Friends of the Earth (FoE) do not like nanoparticle-based sunscreens.  This has been evident for some years – back in 2006 the organization published the report Nanomaterials, Sunscreens and Cosmetics: Small Ingredients, Big Risks, and every year since then they have had something to say on the subject. This year’s web-based piece leaves now doubt [...]

Sunscreens and Alzheimer’s – solid science or scare-mongering speculation?

by Andrew Maynard August 25, 2009

Could using sunscreen lead to Alzheimer’s, Parkinson’s, or other neurodegenerative diseases?  The association seems far-fetched – given the amount of sunscreens, creams and lotions used every day, surely someone would noticed a link by now if it existed!  Yet a press release from the University of Ulster suggests the nanoparticles used in some sunscreens could [...]

Industry critics give nanotechnology sunscreens the thumbs up

by Andrew Maynard July 3, 2009

The Environmental Working Group (EWG) – a US-based non-profit organization committed to using public information to protect public health and the environment – has just released what is probably the most comprehensive evaluation to date of the safety and effectiveness of using titanium dioxide and zinc oxide nanoparticles in sunscreens.  And their conclusion? On balance, [...]

Nano-sunscreens leave their mark

by Andrew Maynard June 21, 2008

Painted metal roofs are cheap, convenient, and usually very durable.  But over the past two years, a rash of accelerated ageing has blighted pre-painted steel roofing in Australia.  And intriguingly the ageing—which affects the coating—seems to be localized to small patches, taking on the form of fingerprints, handprints and even footprints. The culprit it seems [...]
