The most sensitizing single allergens were the hydroperoxides of linalool (1.0 and 0.5% pet.) and limonene (0.3 and 0.2% pet.). Testing with the hydroperoxides of linalool and limonene identified 62 fragrance\u2010sensitized patients (38.3%) who could not be detected by the common fragrance markers. Of all fragrance\u2010sensitized patients, 21 (13.0%) would have been missed when not testing with the fragrance series.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Patch testing with the fragrance series in addition to the EBS is valuable.
