Further, where any Y group is SO, the compounds of the invention are sulfoxides, which can also exist in two enantiomeric forms. Therefore, this form of metol replaced most other developing agents except for hydroquinone, Phenidone which is more recent than metol , and derivatives of Phenidone. The organic co-solvent is preferred to be aprotic, and is more preferably chosen from pentane, hexane, heptane, cyclohexane, benzene, toluene, xylene, tetrahydrofuran, ethyl acetate, diethyl ether, or methyl-tert-butyl ether. There is also some evidence of sensitization dermatitis, in which repeated exposure triggers a chronic condition that is resistant to medication.
