Alcohol

Industrial Uses:  Many

Personal Care Products:  Mouthwashes

Purpose:  Solvent (primarily)

Mouthwashes with an alcohol content of 25% or higher have been implicated in mouth, tongue and throat cancer.  Alcohol acts as a solvent in the mouth making tissues more vulnerable to carcinogens

Men had a 60% higher risk and women a 90% higher risk of these cancers compared to those not using the mouthwash (http://theanswertocancer.com/avoidable-toxins.htm).
