We have tried answering all the questions you might have regarding our zero plastic and environmentally safe products.

Apart from its physical appearance the bio glitter has different physical properties and is made from different raw materials than glitter. Bio glitter uses natural and plant based materials rather than plastic. It is scientifically proven through ISO14851/2 freshwater testing to quickly biodegrade into harmless substances in the natural environment. Bio glitter is designed to biodegrade quickly and safely in natural water environments.


The bio glitter used in SunDust cosmetics has been lab-tested and certified TÜV OK biodegradable WATER. The certification uses as a simple and clear means of communicating this fact to our customers. OK biodegradable WATER certification cuts through the confusion regarding biodegradable glitter. The ISO 14851/2 tests at the heart of this certification are also specified by ECHA (European Chemicals Agency) determining if material is considered a microplastic

Bio glitter does not dissolve in water by itself, it needs bacteria and microorganisms to degrade in the water environment. Once in the water microbes will eat away at the bio glitter, turning it into carbon dioxide, water and biomass. In a microbe-free environment, the bio glitter is completely inert.

No microbes = No micro-degradation

Sunscreens with a sun protection factor (SPF) of 4 and above are listed on the Australian Register of the Therapeutic Goods Administration. Products can only be listed on the register if they comply with the Australian/New Zealand Standard for sunscreen products (AS/NZS 2604:2012). The highest SPF for sunscreen available in Australia is SPF50+. The SPF number is only a guide. In laboratory conditions, when used as directed, SPF30 sunscreen filters 96.7% of UV radiation and SPF50 filters 98%. Both provide excellent protection if they are applied properly.

Many Australians apply too little sunscreen and forget to reapply. Sunscreen should be reapplied every two hours if you are spending time outdoors. As sunscreen can be easily wiped off, lost through perspiration you should also reapply after swimming, sweating, or towel drying. Sundust bio glitter sunscreen makes this easy. When the glitter wears off, you know it is time to reapply! We have found that the bio glitter will also encourage children to reapply, because they love to sparkle in the sun!

There are different types of UV radiation. UVA radiation penetrates deep into the skin, affecting the living skin cells that lie under the skin’s surface. UVA causes long-term damage like wrinkles, blotchiness, sagging, and roughening, and also contributes to skin cancer. UVB radiation penetrates the top layer of skin and is the main cause of skin damage and skin cancer. Broad-spectrum sunscreen filters both UVA and UVB radiation.

There is clear evidence that regular use of sunscreens helps prevent skin cancer. Long-term studies of sunscreen use in Australia have found no harmful effects of regular use. There have been questions raised about the safety of sunscreens that contain nanoparticles. The available evidence suggests that nanoparticles used in sunscreens do not pose a risk to health.

Sunscreen should not be used as the only line of defence against UV. When the UV Index is 3 or above, be sure to protect yourself in five ways by:

slipping on sun-protective clothing
slopping on SPF50 or broad-spectrum water-resistant sunscreen
slapping on a broad brim hat
seeking shade when possible, and
sliding on sunglasses.
