It is 100% natural and completely safe and edible (However we don’t suggest eating it!).
If you are concerned about the colour affecting your face, we encourage you to wear a pair of sunglasses and a bandana or facemask to prevent inhaling too much of the colour. We would strongly suggest this if you do suffer from asthma or a similar condition. Likewise, if you are concerned about any of the negative health impacts of the colour, we recommend that you consult a doctor before committing to The Color Run.
