What is antimony and is it in Bioglitter®?
Antimony is a heavy metal used as a catalyst in the production of polyester and some remains after production in the polyester as an impurity. Antimony long term exposure can cause irritation and ultimately can cause more serious health effects.
The total antimony level in Bioglitter® is <0.5ppm (parts per million). This is the limit of the analysis by Inductively Coupled Argon Plasma Spectrometry (ICP-MS) and therefore can be said to be antimony free. Antimony is NOT used in the production process, unlike the production of polyester used in traditional cosmetic and non-cosmetic plastic glitter. Levels of antimony in cosmetic plastic glitter are controlled to maximum 150ppm, correspondingly the antimony levels in non cosmetic plastic glitter are not controlled and therefore significantly higher.
