Holographic Bioglitter: Can it Solve Glitter’s Microplastics Problem

Following the new (EU) Regulation 2023/2055, which took effect on 17 October 2023, bioglitter might become the only sparkling powder available in Europe. The regulation restricts the sale of products containing intentionally added microplastics, including non-biodegradable plastic glitter; however, it allows exceptions for biodegradable, soluble, or natural glitter. This opens the door for eco-friendly alternatives like cellulose-based or mineralbased glitters and holographic biodegradable glitters.
