- Under the test conditions employed, Novozym 230 had a primary irritation score of 0.0 and was classified as a "non irritant" to skin.
- Executive summary:
A test for primary skin irritation in rabbits was carried out with Novozym 230 (batch PPZ1281) according to the Code of Federal Regulations 1979, title 16, § 1500.41 with a few modifications. Instead of 24 hours the rabbits were only exposed to the test substance for 4 hours and readings were made 1, 24, 48 and 72 hours after the exposure had ended.
Under the test conditions employed, Novozym 230 had a primary irritation score of 0.0 and was classified as a "non irritant" to skin.
