Essential oils are very flammable substances. While it may seem like a good idea to use them in the dryer to make all the clothes feel and smell nice, it is a definite fire hazard. The flashpoint for some of these oils is as low as 30 degrees Celsius!

This is why you need to be careful putting anything in the dryer that was exposed to essential oils. And in certain conditions, these essential oils may react with the laundry detergent to break down into chemicals that harm the clothes instead. This wastes both the detergent and the essential oil.
