Some glitters are labelled as biodegradable, however they are made from Polylactic Acid (PLA), this material only biodegrades in an industrial composting machine so is the same as wearing plastic when used on the skin.

Is glitter environmentally friendly?

Cellophane-based glitter Although it may sound environmentally-friendly because it is made from cellulose, a natural plant fiber, it has a chemical structure that means it will not biodegrade in the natural environment.

How do I know if my glitter is biodegradable?

There’s no way to know for sure.” You’d have to take the glitter, immerse it in some water that has microorganisms in it (in other words, not fresh water), leave it open to the air, and wait… at least a few weeks. You could speed up the process by adding sun, or shaking the container every so often.
