Natural rubber latex: Type I immediate hypersensitivity (IgE-mediated, 1-6% prevalence in general population, higher in healthcare workers) — can cause contact urticaria, angioedema, and anaphylaxis. Synthetic elastane (spandex/Lycra): generally well-tolerated but dye and finishing chemicals (formaldehyde resin, AZO dyes) can cause contact dermatitis. Antimicrobial treatments (silver nanoparticle, copper-infused): marketed for odor control — silver may cause argyria with excessive use, copper can irritate sensitive skin.
