216-768-7
EC Name:
tert-butyl acrylate

1663-39-4
Molecular formula:
C7H12O2
IUPAC Name:
tert-butyl acrylate

Purity unknown

Method

Type of population:
occupational
Ethical approval:
not specified
Subjects:
- Number of subjects exposed: 22
Clinical history:
Contact dermatitis
Route of administration:
dermal
Details on study design:
TYPE OF TEST(S) USED: patch test (epicutaneous test)

ADMINISTRATION
- Type of application: occlusive
- Description of patch: The Finn-chamber method with an occlusion time of 24 h was used. The tests were applied on the back with a non-occlusive porous tape (Scanpor® Surgical Tape, Norgeplaster A/S, Norway); or when the back was full of patch tests, the thighs were used.
- Vehicle / solvent: petrolatum
- Concentrations: 1 %
- Testing/scoring schedule: The tests were read on removal and 24 h, 48 h, and 96-120 h after removal (at least 3 readings).


Results and discussion

Results of examinations:
During 1982-1985, 1 out of 22 patients with contact dermatitis tested with 7 different acrylates showed a positive patch test reaction to tert-butyl acrylate (1 % in petrolatum) and one showed slight to moderate irritation at 24 h.
