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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Clinical and experimental studies on oxidized fragrance terpenes as contact allergens

    Författare :Johanna Bråred Christensson; Göteborgs universitet; []
    Nyckelord :autoxidation; contact allergy; limonene; linalool; colophonium; limonene-1-hydroperoxide; limonene-2-hydroperoxide; 15-hydroperoxyabietic acid; 15-HPA; terpenes; local lymph node assay; LLNA; Freunds complete adjuvant test; FCAT; patch testing; laser Doppler imaging; skin irritation; visual reading;

    Sammanfattning : 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. LÄS MER

  5. 4. The Ecology of Floral Signals in Penstemon digitalis

    Författare :Rosalie Burdon; Amy L. Parachnowitsch; James Thomson; Uppsala universitet; []
    Nyckelord :Antimicrobial; Bombus impatiens learning; indirect signal; multimodal; nectar; protandry; signal-reward association; Volatile Organic Compounds VOCs ; Biology with specialization in Ecological Botany; Biologi med inriktning mot ekologisk botanik;

    Sammanfattning : In this thesis, I combined field observations and lab experiments to explore the ecological significance of floral signals in a North American wildflower, Penstemon digitalis. More specifically, to determine the potential mechanisms driving selection on floral scent, I studied how scent mediates interactions with pollinators and antagonists by (1) observing spatiotemporal variation in scent emission (2), floral volatile ability to suppress microbes (3) the honest advertisement of nectar, and (4) if scent could aid pollinator learning by reinforcing visual signals.

  7. 5. Formation of Skin Sensitizers from Fragrance Terpenes via Oxidative Activation Routes. Chemical analysis, Structure Elucidation and Experimental Sensitization Studies

    Författare :Lina Hagvall; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The work presented in this thesis emphasizes the importance of considering oxidative activation in the toxicity assessment of fragrance chemicals. Compounds without contact allergenic properties can be activated either via autoxidation in contact with air or via cutaneous metabolism to reactive products which can cause contact allergy. LÄS MER
