Interpretation of results:

Category 3 based on GHS criteria

Conclusions:

Based on the QSAR done using the OCED toolbox for hexylamine, it was estimated to have LD50 value of 422.78 mg/kg bw cosidering the mortality effect on rats via oral route. Thus it can be concluded that hexalmine is classified as acute toxicity category 3 via oral route as per the new CLP regulation criteria.

Executive summary:

Interpretation of results:

Category 3 based on GHS criteria

Conclusions:

Based on the QSAR done using the OCED toolbox for hexylamine, it was estimated to have LD50 value of470.93 mg/kg bw cosidering the mortality effect on rabbits via dermal route. Thus it can be concluded that hexalmine is classified as acute toxicity category 3 via dermal route as per the new CLP regulation criteria.

Additional information

Hexylamine  is likely to be hazardous by oral and dermal route.

Acute oral toxicity:

Based on the data available for target Hexylamine(CAS no 111-26-2) and its read across amylamine (CAS no 110-58-7) are summarized as below

Based on the prediction done by using QSAR Toolbox 3.3.(2015), acute oral toxicity was estimated in rats by using Hexylamine orally by gavage. 50 % mortality observed at 422.78 mg/kg bw. Therefore, LD50 was estimated to be 422.78 mg/kg when rats were treated with Hexylamine orally by gavage.

In a study given by German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (1996), acute oral toxicity was evaluated in Wistar male rats by using Hexylamine orally by gavage and observed for 14 days. 50 % mortality was observed in treated male rats at 670 mg/kg bw. Therefore, LD50 was considered to be 670 mg/kg be when Wistar male rats were treated with hexylamine.

In a study given by U.S. Department of Commerce National Technical Information Service (1976) for read across, acute oral toxicity was evaluated in rats by using amylamine orally. 50 % mortality was observed in treated rats at 470 mg/kg bw. Therefore, LD50 was considered to be 470 mg/kg bw when rats were treated with amylamine orally. 

Thus, based on weight of evidence for target Hexylamine(CAS no 111-26-2) and its read across amylamine (CAS no 110-58-7) is likely to be hazardous by oral route and as per CLP regulation classified under category III.

Acute dermal toxicity:

Based on the data available for target Hexylamine(CAS no 111-26-2) and its read across amylamine (CAS no 110-58-7) are summarized as below

Based on the prediction done by using QSAR Toolbox 3.3.(2015), acute dermal toxicity was estimated in male and female rabbits by using Hexylamine by occlusive application for 24 hours. 50 % mortality observed at 470.93 mg/kg bw. Therefore, LD50 was estimated to be 470.93 mg/kg when male and female rabbits were treated with Hexylamine by occlusive application for 24 hours.

In a study given by RTECS Chemical Inventory Data Base (2001), acute dermal toxicity was evaluated in rabbits by using Hexylamine by dermal application. 50 % mortality observed in treated rabbits at 318.48 mg/k bw . Therefore, LD50 was considered to be 318.48 mg/k bw when rabbits were treated with Hexylamine by dermal application.

In a study given by U.S. Department of Commerce National Technical Information Service (1976) for read across, acute dermal toxicity was evaluated in rabbits by using amylamine by dermal application. 50 % mortality was observed in treated rabbits at 1120 mg/kg bw. Therefore, LD50 was considered to be 1120 mg/kg bw when when rabbits were treated with Hexylamine by dermal application.

 

Thus, based on weight of evidence for target Hexylamine(CAS no 111-26-2) and its read across amylamine (CAS no 110-58-7) is likely to be hazardous by dermal route and as per CLP regulation classified under category III.

Justification for classification or non-classification

Based on the predicted data available for hexylamine it can be concluded that hexylamine is classified as acute category III via oral and dermal route as per the criteria of new CLP regulation.
