Chemosis was observed in all 3 animals after 1 h and 24 h.Between 48 h and 72 only 2 animals showed chemosis. After 15 d no chemosis was observed in any animal. Discharge was observed in all animals between 1 h and 72 h. After 8 day discharge was only seen in 1 animal which also suffered from suppuration.

Additional information
There are relevant and reliable data available investigating the skin and eye irritation of 1-Butanaminium, N,N-dibutyl-N-methyl-, methyl sulfate.
Skin:
OECD Guideline Study:
The potential of 1-butanaminium, n,n-dibutyl-n-methyl-, methyl sulfate to cause acute dermal irritation or corrosion was assessed by a single topical application of 0.5 ml of the test substance to the intact skin of 3 white new zealand rabbits for 4 hours under semiocclusive dressing according to OECD guideline 404 under GLP. The average score (24 to 72 hours) for irritation was calculated to be 1.2 (1.3; 1; 1.3) for erythema and 0.0 for edema. The skin findings were reversible in 2 animals after 72 hours or 8 days, while erythema was still present in 1 animal at study termination (15 days after removal of the patches). Hence under the test conditions chosen and considering the described findings 1-butanaminium, n,n-dibutyl-n-methyl-, methyl sulfate does not give indication of an irritant property to the skin (BASF 1998).
Eye:
OECD Guideline Study:
The potential of 1-butanaminium, n,n-dibutyl-n-methyl-, methyl sulfate to cause damage to the conjunctiva, iris or cornea was assessed in 3 white new zealand rabbits, subjected to a single ocular application of 0.1 ml of the test substance on day 0 according to OECD guideline 405 under GLP.The average score (24 to 72 hours) for irritation was calculated to be 0.0 for corneal opacity, 0.2 (0; 0; 0.67) for iris, 2.6 (2.33; 2.67; 2.67) for conjunctivae redness and 1.2 (1.33; 0.33; 2) for chemosis. The findings were reversible in all animals within 15 days after application. Symptom observed and described in the respective observation in detail together with the average score for irritation indicates an irritant property of the test substance to the eye. Hence, under the test conditions chosen and considering the described findings 1-butanaminium, n,n-dibutyl-n-methyl-, methyl sulfate gives indication of an irritant property to the eye (BASF, 1998).
As there is only one reliable and relevant study available for each endpoint and no further information indicate anymore critical results, these studies were integrated as key study.
Assessment for skin and eye irriation:
Based on the available studies on skin and eye irritation the substance is not skin irritating but eye irritating
(according to actual classification guidelines).
Effects on eye irritation: irritating
Justification for classification or non-classification
Based on the above information and according to Regulation (EC) 1272/2008 or Directive 67/548/EEC, a classification of the substance as skin irritant is not justified but for eye irritant a classification is necessary.
Skin:
-GHS: no classification
-DSD: no classification
Eye
-GHS: CAT 2A, H319
-DSD: Xi, R36
