4. 2. Contact allergy to fragrances. With a focus on hydroperoxides of linalool and hydroperoxides of limonene

   Author : Thanisorn Sukakul; Yrkes- och miljödermatologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; contact allergy; fragrance; repeated open application test ROAT ; limonene; linalool; oxidized terpenes;

   Abstract : Patch testing with fragrance allergens has been performed for over half a century, and the protocol has been continually developed and standardised. Fragrance mixes I and II and Myroxylon pereirae resin are commonly used as screening fragrance allergens in patch testing. READ MORE

5. 3. Allergenic Oxidation Products from Fragrance Terpenes. Chemical Analysis and Determination of Sensitizing Potency

   Author : Johanna Rudbäck; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Autoxidation; Contact allergy; Essential oils; Fragrances; Hydroperoxides; Ionization techniques; Mass spectrometry; Prehapten; Sensitization; Skin; Structure-activity relationships; Terpenes;

   Abstract : The ubiquitous presence of fragrance compounds in consumer products has resulted in a high frequency of contact allergy to fragrances in the population. For prevention purposes and according to EU regulations, cosmetics must be labeled when containing the most prominent fragrance allergens in concentrations exceeding 0. READ MORE

6. 4. Limonene Hydroperoxides in Allergic Contact Dermatitis. Radical Formation, Sensitizing Capacity and Immunogenic Complex Formation

   Author : Staffan Johansson; Göteborgs universitet; []

   Abstract : The work presented in this thesis aims to improve the possibilities for diagnosing contact allergy to oxidized limonene and linalool and to, in patients, study contact allergy from structurally closely related hydroperoxides with regard to their specificity, potency and cross-reactivity. The fragrance terpenes limonene (from citrus oil) and linalool (from lavender oil) are widely used in household and industrial products. READ MORE
