[Atomic-S (OP)]

While using a common household powdered cleanser on a bathroom fixture, I became aware of its odor, and that it appeared to be being blown in my face by the direction of air currents in the room.  Then I noticed that the cleanser contains limestone and feldspar.  A number of mineral dusts have been found to lead to lung cancer or other lung diseases.  It appears that those who use these cleansers must frequently inhale dusts from them. Are they safe?
