A patch test with a series of 28 (meth-)acrylates was used to test patients for allergic contact dermatitis caused by these substances. 1,6-Hexanedioldiacrylate (HDDA) was one out of the 28 substances tested. However, no detailed data for HDDA were reported and previous exposure to HDDA is highly unlikely at least for the 4 dermatitis cases described.

Materials and methods

Type of sensitisation studied:
Study type:
case report
Principles of method if other than guideline:
Patients with contact dermatitis were tested for sensitization of 28 commercial (meth-)acrylates using the Finn-chamber method (Contact dermatitis 1: 48-52, 1975) with an occlusion time of 24 hours. After removal of the test substance at least 3 readings were made.

- Testing/scoring schedule: exposure of the test material for 24 h under occlusive conditions, removal of the test substance, readings after removal and 24 h, 48 h, and 96-120 h after removal (at least 3 readings) by a dermatologist.

Results and discussion

Results of examinations:
12 of 24 patients showed no reaction to the (meth-)acrylate series. 3 were found to have a relevant allergic reaction and were diagnosed as having an occupational allergic contact dermatitis to acrylates. 9 patients showed a slight irritation at the 24 h and 48 h readings, sometimes also at 72-96 h, three of these were sensitized. No detailled information was given regarding reactions to HDDA.
