An oil I’m using says ‘Suspected of damaging fertility of the unborn child (exposure route). Is it safe for use in candles?

Some of our fragrances do carry this hazard in their raw form. Once diluted, this hazard is no longer applicable. If ever in doubt, check the 8% or 10% SDS that is available via the website for hazards applicable to your candles or wax melts. In any case, we recommend using the appropriate PPE when handling ALL fragrance.
