Bioglitter and ‘OK Biodegradable WATER’ Certification

Cosmetic Bioglitter PURE is ‘OK Biodegradable WATER’ certified – A world first!


Cosmetic Bioglitter SPARKLE and Deco Bioglitter SPARKLE:  are not currently OK Biodegradable Water certified, however, ISO14851 testing demonstrates we are only 3% off meeting the biodegradability performance criteria to become certified.  As we remove the last bit of plastic from SPARKLE and replace it will plastic free elements, it will allow us to improve the biodegradability performace, enabling SPARKLE to become Certified.
