Banana Boat Sunscreens and Nanotechnology

There has been some concern about the use of nanoparticles in sunscreen and the negative effect they can have on our health. Choice have written an article on the topic which describes the term in detail.

In reaction to the nanotechnology debate, Banana Boat have released a statement and you can read about their position below…

Banana Boat sunscreens and nanotechnology

Do any Banana Boat sunscreens contain nanoparticles?

No nanoparticles (i.e. particles smaller than 100 nanometres is size) are used in any Banana Boat sunscreens manufactured andsold in Australia.

All ingredients used in Banana Boat sunscreens that are sold in Australia are approved by the Therapeutic Goods Administration (TGA), and therefore are safe for consumers to use everyday as a form of protection from UVA and UVB rays.

As stipulated by the TGA, all active ingredients in Banana Boat sunscreens are listed on the label found on the back of the packaging.

While Banana Boat sunscreens do not contain nanoparticles, we will continually monitor the issue and work cooperatively with the TGA and external parties if any action is required.

Some Banana Boat sunscreens contain micronised Zinc Oxide. Are these the same as nanoparticles?

The micronised ingredients found in Banana Boat sunscreens are not nanoparticle sized. These are larger particles that do not penetrate the outer layer of the skin.

Background information

What is ‘nanotechnology’?

The term “nanotechnology” does not describe a single technology. It is applied to materials, systems and processes that operate at the extremely small scale of 100 nanometres (nm) or less. To put 100nm in context: a strand of DNA is 2.5nm wide, a red blood cell is 7,000 nm and a human hair is 80,000 nm wide. Nanoparticles of titanium dioxide and zinc oxide now used in sunscreens measure 20-30nm in size or even smaller.

What is the government’s position on this?

A review by the TGA on the ‘A review of the scientific literature on the safety of nanoparticulate titanium dioxide or zinc oxide in sunscreens’ can we found on the following website http://www.tga.gov.au/pdf/review-sunscreens-060220.pdf

  1. Toddler sunscreens are as effective for a adults. They simply don’t have the unnecessary scent and chemicals. e.g. Paraben Free.
