On April 30, 2022, Samaran, Quentin; Raison-Peyron, Nadia; Clark, Evangeline; Svedman, Cecilia; Dahlin, Jakob; Dereure, Olivier; Bruze, Magnus; Bourrain, Jean Luc published an article.Recommanded Product: 2-Ethylhexyl 2-cyano-3,3-diphenylacrylate The title of the article was A new case of photoallergic contact dermatitis caused by benzophenones in magazine covers. And the article contained the following:
Allergic contact dermatitis (ACD) and photoallergic contact dermatitis (PACD) to benzophenone present in printing ink have been reported. However, precise chem. analyses and extended photo-patch tests have not been performed in these cases. To determine which component present in a magazine cover are responsible for a patient’s skin reaction, to determine the primary sensitizer, and precisely diagnose ACD and PACD. After initial photo-patch tests were performed on a patient with a history of reaction to magazine covers after sun exposure, gas chromatog.-mass spectrometry and high-performance liquid chromatog. analyses of the magazine covers, and addnl. photo-patch tests were performed. The first photo-patch test results confirmed PACD to ketoprofen and fenofibrate and evoked PACD to the magazine covers. 4-Me benzophenone (4-MBP) and 1-hydroxy-cyclohexyl-phenyl-ketone (1-HCPK) were found in the magazine cover. Addnl. photo-patch tests confirmed PACD to 1-HCPK and to benzophenone, and photo-aggravated ACD to 4-MBP. The primary sensitizer was ketoprofen. Benzophenones are present in a wide variety of products, without always being listed on the packaging. Patients previously sensitized to other ketones, such as ketoprofen, may react to benzophenones without being able to avoid contact with these mols. New regulations may be needed for more efficient eviction advice. Photoallergic contact dermatitis to covers of a magazine was diagnosed and thorough investigation was necessary to identify the haptens responsible. Chem. analyses of the covers revealed the presence of 4-Me benzophenone (4-MBP) and 1-hydroxy-cyclohexyl-phenyl-ketone (1-HCPK) Photo-patch tests suggested photo-aggravation of contact dermatitis to 4-MBP and benzophenone, and photoallergy to 1-HCPK and ketoprofen. Ketoprofen was the most likely primary sensitizer. The experimental process involved the reaction of 2-Ethylhexyl 2-cyano-3,3-diphenylacrylate(cas: 6197-30-4).Recommanded Product: 2-Ethylhexyl 2-cyano-3,3-diphenylacrylate
