I am constantly subjected to sceptics who think Scentsy is harmful, ie not an essential oil and emmits petrochemicals. I need some solid back-up please for ammunition. Recently i invited several people i know to a party and was surprised to get some pretty hostile letters back about what i was selling. I understand the warming vs burning concept and not evaporating wax but what exactly IS released into our homes...fragrance is almost everywhere but what exactly is it and the wax being a oil product is it classified as a petro chemical? I love my scentsy, i give them personal backup as i live with a highly allergic husband and an athsmatic child who have never reacted but i would just love something in print. thanks for your time.
