This biodegradable .004 cosmetic glitter can be used in all applications and is every bit as sparkly as it conventional PET based counterpart. Bio glitter is derived from sustainable and environmentally sourced raw materials produced and harvested to FSC standard. Bio glitter will not biodegrade on the shelf. Biodegradation will only be initiated in soil, compost or waste-water environments where micro-organisms are present. The combination of heat, water and oxygen enable micro-organisms to effectively break it down.
