Can Aerosol Sunscreens Cause More Harm Than Good?
An investigation carried by one of Australia's Leading manufacturers in Sunscreen highlighted the potential dangers of aerosol sunscreen. It was conducted sing basic research and laboratory testing whilst using an aerosol sunscreen that is currently on the market.
Whilst we do not disagree with the convenience of the product and that it could encourage people to use sunscreen when they otherwise may not have and that there is a consumer demand for such products
The research indicated :
1. Flammability As previously noted, there have been instances in the United States where people have caught on fire after applying aerosol based sunscreen products, causing serious burns
2. Asphyxiation Asphyxiation refers to breathing in a gas/propellant with a reduced amount of oxygen in the air which lowers oxygen concentration in the blood stream, potentially leading to unconsciousness.
3. Explosion No sunscreen should be left in a car which is in the sun (especially during summer) or exposed to direct sunlight or left anywhere where it may be exposed to temperatures over 30C
4. SPF testing and certification The sun protection factor (SPF) of aerosol sunscreens aren’t tested and certified in the laboratory using the same application methods used for regular sunscreens and by us as consumers
5. Loss during application Because of the gas/propellant and the fine mist released during use, the amount of product that comes out of a can of aerosol sunscreen is not the same as what ends up on our skin
6. Change in pressure and amount applied Over the life of an aerosol as the product is used, the amount of product/propellant in the can becomes less and this reduces the pressure within the aerosol
7. Understanding the application properties To achieve the claimed SPF for regular sunscreen (non-aerosol), the average adult requires approximately 36g of product when being applied over the entire body
Results indicated This means that for the average adult applying sunscreen to their entire body, you should be getting only 2 applications from the average 175g can (2 applications x 90g = 180g, a fraction more than the 175g in the average aerosol).
So Question remains, So, should I use aerosol sunscreen????
