Allergic contact dermatitis caused by dipropylene glycol diacrylate in the Omnipod insulin pump was written by Ulriksdotter, J.;Svedman, C.;Bruze, M.;Mowitz, M.. And the article was included in British Journal of Dermatology in 2022.Product Details of 4074-88-8 This article mentions the following:
Cases of allergic contact dermatitis (ACD) caused by isobornyl acrylate (IBOA) in the Omnipod insulin pump have previously been reported. To present three cases of patients with ACD caused by a new allergen in the pump, and results from chem. analyses. Omnipod pumps from different batches were analyzed by gas chromatog.-mass spectrometry. Aimed testing, with the department’s medical device (MD) series and substances identified in the pump including dipropylene glycol diacrylate (DPGDA) at 0·01% and 0·1% in petrolatum (pet.), was performed. Patch testing also included extracts from the device, the adhesive patch as is, and allergens from baseline series. All patients tested pos. to 0·1% DPGDA in pet., and two patients addnl. to a 0·01% concentration DPGDA was found in extracts of the Omnipod pumps brought by the patients. An Omnipod pump from an earlier batch contained tripropylene glycol diacrylate, IBOA, N,N-dimethylacrylamide, di(ethylene glycol)ethyl ether acrylate (DEGEA) but no DPGDA. One of the patients reacted pos. to all of these allergens except DEGEA, which was not tested. When suspecting ACD to MDs, DPGDA at 0·1% in pet. should be tested. The contents of Omnipod have changed over time. Patch testing with updated test series and relevance assessment of pos. reactions is a delicate task. Children, with lifelong use of MDs, risk contracting many allergies with potential cross-allergies. A question should be raised as to whether these low mol. weight acrylates should be used at all in devices constantly worn on the skin. In the experiment, the researchers used many compounds, for example, Diethyleneglycoldiacrylate (cas: 4074-88-8Product Details of 4074-88-8).
Diethyleneglycoldiacrylate (cas: 4074-88-8) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Product Details of 4074-88-8
