OK, I can't tell you the good without telling you the bad. This was sent to me by someone who read my post regarding the many uses of Bounce.
Most commercial dryer sheets are impregnated with all sorts of toxic chemicals including Benzyl Acetate, Benzyl Alcohol, Chloroform and Linalool; none of which are good for the environment - or you. Some of these compounds are known carcinogens.
Aside from the chemicals in the sheets winding up in your clothing and therefore next to your skin, when heated, the fumes are also toxic.
