The study was conducted on four fragrance markers in the baseline series: fragrance mix I (FM I), Myroxylon pereirae, fragrance mix II (FM II), and hydroxyisohexyl 3-cyclohexene carboxaldehyde. Around 658 patients showed allergy due to fragrance ingredients when the patch test was performed. In other study, out of 1253 patients, 90% of the FM I and M. pereirae detected 90% of the cases.
