Contact dermatitis to fragrances.
2 groups of patients (1200 and 1500 respectively) were patch tested with different concentrations of perfume mix and fragrance raw materials. The study was to evaluate the incidence of contact dermatitis to fragrances in Roma, Italy, and the influence of limited variations in fragrance and perfume mix concentrations on patch test responses. The results showed that a decrease in the perfume mix concentration from 16% to 8% correlated with a decrease in the % of positive patients (from 5.2% to 3.6%). Variations in the concentration of fragrance raw materials did not influence the % of positive reactions in the 2 groups. The perfume mixture at 16% or 8% gave some positive results, without a corresponding reaction to any of the constituents, that were not related to an excited skin syndrome.
