Abstract
Data on allergic contact dermatitis from acrylates and 4 patients sensitized during routine patch testing are reported. During 1982–1985, we used 7 different acrylates for tests. 1 patient out of 22 (=4.5%) was sensitized to ethyl acrylate and butyl acrylate (1% pet.). Since September 1985, we have used a commercial (meth)acrylate series containing 28 substances. 3 of 24 patients tested became sensitized to ethyl acrylate, 2‐hydroxyethyl acrylate and 2‐hydroxypropyl acrylate (0.5% pet.). Because active sensitization with acrylates can be very harmful, it may be necessary to use lower concentrations than recommended. Currently, we test ethyl acrylate, 2‐hydroxyethyl acrylate and 2‐hydroxypropyl acrylate at 0.167% pet.
