Area of Science:

Dermatology
Allergology
Contact Hypersensitivity

Background:

Fragrance Mix II (FM II) was developed to identify contact hypersensitivity (CH) to fragrances not previously detectable.
Previous diagnostic tools were insufficient for certain fragrance allergens.

Purpose of the Study:

To determine the prevalence of CH to FM II and its individual components in Hungary.
To assess the diagnostic utility of FM II in a Hungarian population.

Main Methods:

A multicenter study conducted from 2009 to 2010 involving 565 patients with suspected fragrance-induced skin symptoms.
Patch testing using standardized allergens including FM II, FM I, and specific fragrance components like citral, coumarin, and Lyral (hydroxy-isohexyl-3-cyclohexene-carboxaldehyde).

Main Results:

Overall fragrance CH was detected in 28.8% of patients.
CH to FM II was identified in 17.2% of the study population.
Specific components showed varying frequencies: hydroxy-isohexyl-3-cyclohexene-carboxaldehyde (7.3%), coumarin (5.1%), α-hexyl-cinnamaldehyde (3.5%), citral (3.4%), farnesol (2.5%), and citronellol (1.2%).

Conclusions:

The prevalence of CH to FM II in the selected Hungarian population is 17.2%.
FM II and its components are crucial for diagnosing fragrance allergies that might otherwise go undetected.
The study underscores the clinical significance of FM II in identifying specific fragrance sensitivities.
