C.)Meta-aminophenol is found to be moderately toxic when introduced to the system via ingestion. It is a skin and eye irritant.

Causes irritation to mucous linings in eyes, respiratory tract and gums. It can act as a mild narcotic. It can also cause dermatitis.


Nail lacquer solvent.

It is oxidized by the liver to form carbon dioxide and water. It is generally not considered an occupational health hazard, however it is a safety hazard due to its flammability.



(S.D. Alcohol)

The term "S.D.A." or "S.D. Alcohol" means ?specifically denatured alcohol?. S.D.A. is ethyl alcohol, to which another substance, such as methyl isobutyl ketone, has been added, making it unfit for human consumption.
