Does Bioglitter™ contain aluminium, and if so, how can it still be called biodegradable?
Bioglitter™ SPARKLE product ranges contain a very small amount of aluminium, used to give it it’s shine. The aluminium layer in Bioglitter™ SPARKLE is extremely thin, more than 200 times thinner than a human hair and is neither toxic nor ecotoxic.
Aluminium is the most abundant metallic element in the earth’s crust and as its a metal it’s inorganic (non-carbon containing) and does not biodegrade. However, materials that do not biodegrade are not necessarily harmful to the environment, for example, water another inorganic material does not biodegrade. Biodegradability tests evaluate how well organic materials (carbon containing compounds) biodegrade in a particular environment, within a particular time frame.
