Titre : Preparation of an oakmoss absolute with reduced allergenic potential Type de document : texte imprimé Auteurs : Chris Ehret, Auteur ; P. Maupetit, Auteur ; M. Petrzilka, Auteur ; G. Klecak, Auteur Année de publication : 1992 Article en page(s) : p. 121-130 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Evernia prunastri' 'Oakmoss absolue' 'Acides aminés' Désensibilisation Extraits Allergènes Index. décimale : 668.5 Parfums et cosmétiques Résumé : Oakmoss absolute, an extract of the lichen Evernia prunastri, is known to cause allergenic skin reactions due to the presence of certain aromatic aldehydes such as atranorin, chloratranorin, ethyl hematommate and ethyl chlorohematommate.
In this paper it is shown that treatment of Oakmoss absolute with amino acids such as lysine and/or leucine, lowers considerably the content of these allergenic constituents including atranol and chloratranol. The resulting Oakmoss absolute, which exhibits an excellent olfactive quality, was tested extensively in comparative studies on guinea pigs and on man. The results of the Guinea Pig Maximization Test (GPMT) and Human Repeated Insult Patch Test (HRIPT) indicate that, in comparison with the commercial test sample, the allergenicity of this new quality of Oakmoss absolute was considerably reduced, and consequently better skin tolerance of this fragrance for man was achieved.DOI : 10.1111/j.1467-2494.1992.tb00047.x En ligne : https://onlinelibrary.wiley.com/doi/10.1111/j.1467-2494.1992.tb00047.x Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=26590

Also, the study of late barrier function restoration events (epidermal cell proliferation and terminal differentiation), outlined that treatment with Arct'Alg also improves barrier function recovery, which was compromised by acetone. This additional benefit may be directly related to its moisturising properties, since water content of the very superficiel epidermal layers regulates the catalytic activity of a number of enzymes, including enzymes responsible for the processing of filaggrin precursor protein.13 Barrier recovery improvement may also be the consequence of metabolic activation induced by some constituents of the Arct'Alg extract.
