Journal of Vinyl and Additive Technology, EarlyView.Flame‐retardant polyurethane composites were synthesized by in situ polymerization. Fire performance and thermal decomposition of boron‐bearing compounds in PU were examined. ABSTRACT Boron compounds exhibit low toxicity and diverse molecular structures, rendering them effective flame‐retardant additives in polymer‐based materials through various ...

Contact Dermatitis, EarlyView.This study analyzes patch test data from 23 969 patients with occupational dermatitis to characterise sensitization to bisphenol A diglycidyl ether (DGEBA), reactive diluents, and amine hardeners. The findings show an overall decline in DGEBA sensitization with fluctuations, substantial co‐sensitization, and markedly increased risks in construction ...

Contact Dermatitis, EarlyView.We report three cases of allergic contact dermatitis (ACD) caused by acrylic resins used in creative hobbies, rather than by epoxy resins, despite these products being incorrectly labelled as “epoxy UV” resins. ABSTRACT Background Several cases of contact allergy to epoxy resins used in creative hobbies have been reported in recent years but not to ...

Contact Dermatitis, EarlyView.A case series of eight patients with allergic otitis externa from contact allergy to hearing aid ear moulds is presented. All were patch test positive to tetrahydrofurfuryl methacrylate and three to isobornyl acrylate. It is postulated that these are likely relevant allergens present in such devices. ABSTRACT Background Allergic contact dermatitis from

Patch Test Results With Dental Series: An 18‐Year Retrospective Study
Contact Dermatitis, EarlyView.Patch testing with dental series is recommended for patients with oral symptoms and/or a history of allergic contact dermatitis ‐ particularly before dental procedures. Routine pre‐implantation patch testing should be considered only on an individual basis rather than as a standard practice.

Contact Dermatitis, EarlyView.In 127 matched nail cosmetics, 2‐hydroxyethyl methacrylate (HEMA) and Di‐HEMA trimethylhexyl dicarbamate (Di‐HEMA TMHDC) listings decreased by approximately 75% between 2023 and 2026. Several other (meth)acrylate‐related ingredients also showed substantial increases or decreases.
