The present studies were performed to compare the differences between sensitization potency of fragrance mix and its ingredients (oak moss absolute, isoeugenol, eugenol, cinnamal, hydroxycitronellal, geraniol, cinnamic alcohol, alpha amyl cinnamal), by using ex vivo LLNA-BrdU ELISA. The SI and EC3 values were calculated and potency classification was found for the mixture and for each ingredients. T(H)1 cytokines (IL-2, IFN-gamma) and T(H)2 cytokines (IL-4, 1L-5) releases from lymph node cell culture were also investigated as contact sensitization endpoints. The EC3 values were calculated and the potency of contact sensitization were classified for fragrance mix, oak moss absolute, isoeugenol, eugenol, cinnamal, hydroxycitronellal, geraniol, cinnamic alcohol, alpha amyl cinnamal respectively: 4.4% (moderate), 3.4% (moderate), 0.88% (strong), 16.6% (weak), 1.91% (moderate), 9.77% (moderate), 13.1% (weak), 17.93% (weak), 7.74% (moderate). According to our results it should be concluded that exposure to fragrance mix does not constitute an evidently increased hazard compared to exposure to each of the eight fragrance ingredients separately. Cytokine analyses results indicate that both TH1 and TH2 cytokines are involved in the regulation of murine contact allergy and can be considered as useful endpoints. (C) 2014 Elsevier Ltd.
