The Draize system of classification, which is separate from the Federal Register test, would regard the test substance as a severe irritant to the skin. Further, according to CLP criteria (EC 1272/2008) , the test substance may be considered to be Category 2 skin irritant as the mean scores of erythema and edema were >2.3 after 72 h.
- Executive summary:
A study was conducted to assess the skin irritation potential of test substance, amides, C18 -unsatd., N,N-bis(hydroxyethyl) to the rabbit skin in accordance with Title 21, Code of Federal Regulations, 191.11.
Six animals were treated with undiluted 0.5 mL (0.5 g) of the test substance. The treated areas were covered with a semi-occlusive gauze patch and taped to maintain the test substance in contact with the skin for a duration of 24 h. The degree of erythema and edema were recorded according to Draize scoring system after 24 and 72 h.
Moderate to severe erythema and defined edema was observed at 24 h and moderate to severe erythema and moderate edema was observed at 72 h on the abraded and intact rabbit skin. The meanprimary skin irritation index (PII) was 5.5.

Additional information
Skin irritation
A study was conducted to assess the skin irritation potential of the read across test substance to rabbit skin in accordance with Title 21, Code of Federal Regulations, 191.11. Six animals were treated with undiluted 0.5 mL (0.5 g) of the test substance. The treated areas were covered with a semi-occlusive gauze patch and taped to maintain the test substance in contact with the skin for a duration of 24 h. The degree of erythema and edema were recorded according to Draize scoring system after 24 and 72 h. Moderate to severe erythema and defined edema was observed at 24 h and moderate to severe erythema and moderate edema was observed at 72 h on the abraded and intact rabbit skin. The mean primary skin irritation index (PII) was 5.5. Under the test conditions, the test substance had an irritant effect on the skin and was classified as irritating according to the definitions given in the U.S. Federal Hazardous Substances Act. Further, according to CLP criteria (EC 1272/2008) the test substance may be considered to be Category 2 skin irritant as the mean scores of erythema and edema were >2.3 after 72 h (Casey LM, 1976).
Eye irritation
A study was conducted to assess the ocular irritation potential of the read across test substance, amides, C18 -unsatd., N,N-bis(hydroxyethyl) using New Zealand white rabbits in accordance with Title 21, Code of Federal Regulations, 191.11. A volume of 0.1 mL or 0.1 g the test substance was instilled into one eye of each of six New Zealand white rabbits; the other eye served as control. The eyes were evaluated for damage to cornea, iris and bulbar and palpebral conjunctivae at 24, 48, 72 h and 7 and 14 d. Irritation response in the conjuctiva was observed in terms of redness, chemosis and discharge. The mean conjunctival redness score was 2 in 4/6 animals. Further, mean irritation score of 11.33, 7.67, 5.67, 3.33 and 2.33 was observed after 24, 48 and 72 h and 7 and 14 days of observation. Except for conjunctival redness, which was the most prominent response and was present in 3/6 animals, the remaining eye irritation response (i.e., chemosis and discharge) were reduced to almost 0 by Day 14. Under the test conditions, the undiluted test substance can be assessed to be a irritating to the eyes. According to CLP criteria (EC 1272/2008) the test substance can be considered to be a category II- eye irritant (with reversible effects on the eye (Casey LM, 1976).
Another study was conducted to assess the ocular irritation potential of the read across substance amides, C18 -unsatd., N,N-bis(hydroxyethyl) using New Zealand white rabbits in accordance with Title 21, Code of Federal Regulations, 191.11. A volume of 0.1 mL or 0.1 g the 5% diluted test substance in distilled water was instilled into one eye of each of six New Zealand white rabbits; the other eye served as control. The eyes were evaluated for damage to cornea, iris and bulbar and palpebral conjunctivae at 24, 48 and 72 h. The mean irritation score of 1.0, 0.0 and 0.0 was observed after 24, 48 and 72 h of observation. Under the test conditions, the 5% diluted test substance was assessed to be non-irritating to the eyes and not classified according to CLP criteria (EC 1272/2008 (Casey LM, 1976).
Justification for selection of skin irritation / corrosion endpoint:
Only key study available, conducted on the read across substance amides, C18(unsatd.), N,N-bis(hydroxyethyl); the study was conducted in accordance with Title 21, Code of Federal Regulations, 191.11.
Justification for selection of eye irritation endpoint:
The data showing the most severe effects was chosen as the key study. The study was well conducted on the read across substance amides, C18(unsatd.), N,N-bis(hydroxyethyl) in accordance with Title 21, Code of Federal Regulations, 191.11.
Effects on skin irritation/corrosion: irritating
Effects on eye irritation: irritating
Justification for classification or non-classification
Skin
Based on the available reliable in vivo skin irritation study conducted according to the code of federal regulations, a 24-h, semi-occlusive exposure to the structural analogue amides, C18 -unsatd., N,N-bis(2 -hydroxyethyl) clearly indicates irritation response to skin. Hence, the data derived from the key study justifies R38 classification according to EC criteria (67/548/EEC) and skin irritation category 2; H315-causes skin irritation (hazard statement) according to CLP criteria (EC 1272/2008).
Eye
Based on the available reliable in vivo eye irritation study conducted according to the code of federal regulations, an instillation of the undiluted structurally analogous test substance amides, C18 -unsatd., N,N-bis(hydroxyethyl) into rabbit eyes clearly indicates irritation response. However, instillation of 5% diluted read across test substance into rabbit eyes in another supporting study, did not reveal significant eye irritation response and was assessed to be non-irritating to the eyes. Since the conjuctival redness score observed in the key study with the undiluted test substance, was 2 in 4/6 animals, Category 2; H319 (hazard statement) is warranted according to CLP criteria (EC 1272/2008) classification. On this basis, it is assumed that HE Rape Oil, reaction product with diethanolamine will be irritating to both the skin and the eyes also.Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
