Description of key information
Following a 4 hour occluded exposure to rabbit skin, undecanol (branched and linear) was not a skin irritant (group mean 24+48+48 hour scores <2) (Biolab 1985; rel 2). The test substance was however, found to be an eye irritant based on 24+48+72 hour scores for conjunctival redness of 2 in all rabbits and persistence to 7 days (Biolab 1985; rel 2).
