In this retrospective study, 103 patients with suspected fragrance allergy were patch tested to linalool 10% petrolatum (pet), hydroperoxides of linalool 1% pet, D-limonene 10% pet, and/or the hydroperoxides of D-limonene 0.3% pet between July 9, 2014, and October 25, 2016. Linalool is a naturally occurring terpene, present in large amounts in various plants, for example in lavender, rosewood, bergamot and jasmine.
Their primary oxidation products formed after air exposure, the hydroperoxides, have been recognized as important contact haptens. Overall, the most frequently studied fragrance hydroperoxides are lim-2-OOH, linalool-6hydroperoxide (lin-6-OOH) and linalool-7-hydroperoxide (lin-7-OOH). Limonene and linalool are among the most common fragrance terpenes used in everyday products. Hydroperoxides of Linalool (H-031A, H-031B) Your patch testing results indicate that you have a contact allergy to Hydroperoxides of Linalool. The sensitizing ingredients in the oxidation mixtures are hydroperoxides (HP).
