Description of key information
Acute Oral Toxicity:
The LD50 was estimated to be 5998.58 mg/kg bw,when male and female Wistar rats were orally exposed with Black Pepper Oil (8006-82-4) via gavage.Thus, comparing this value with the criteria of CLP regulation,Black Pepper Oil (8006-82-4) can be “Not classified” for Acute Oral Toxicity.
Acute Dermal Toxicity:
The LD50 value was estimated to be 2733.84 mg/kg bw,when male and female New Zealand White rabbits were exposed semiocclusively with Black Pepper Oil (8006-82-4)by dermal application for 24 hours.Thus, comparing this value with the criteria of CLP regulation, Black Pepper Oil (8006-82-4) can be “Not classified” for Acute Dermal Toxicity.

Additional information
Acute Oral Toxicity:
In different studies, Black Pepper Oil (8006-82-4) has been investigated for acute oral toxicity to a greater or lesser extent. Often the studies are based on in vivo experiments and estimated data in rodents, i.e. most commonly in rats for Black Pepper Oil (8006-82-4).The predicted data using the OECD QSAR toolbox has also been compared with the experimental studies. The studies are summarised as below:
In a prediction done by SSS (2017) using the OECD QSAR toolbox with log kow as the primary descriptor, the acute oral toxicity was estimated for Black Pepper Oil(8006-82-4).The LD50 was estimated to be 5998.58 mg/kg bw,when male and female Wistar rats were orally exposed with Black Pepper Oil(8006-82-4) via gavage.
In another experimental study conducted by D. L. J. Opdyke (Food and Cosmetics Toxicology,Volume 16, Supplement 1, 1978, Pages 651-652) for the target substance Black Pepper Oil(8006-82-4). Acute oral toxicity study was done in rats using test material Black Pepper Oil (8006-82-4).No mortality was observed at dose 5000 mg/kg bw. Hence,LD50 value was considered to be >5000 mg/kg bw,when rats were treated with Black Pepper Oil (8006-82-4)orally.
In another experimental study conducted by U.S. National Library of Medicine (Chemidplus Database,U.S. National Library of Medicine,2017) and IFA GESTIS (Gestis Substance Database,2017) for the structurally similar read across substance (+)-Limonene (5989-27-5). Acute oral toxicity study was done in rats using test material (+)-Limonene (5989-27-5).50% mortality was observed at dose 4400 mg/kg bw.Clinical signs like behavioral changes in motor activity (specific assay) and changes in lungs and thorax were observed.Respiratory function tests were depressed.Hence,LD50 value was considered to be 4400 mg/kg bw,when rats were treated with(+)-Limonene (5989-27-5)orally.
In another experimental study conducted by U.S. National Library of Medicine (Chemidplus Database,U.S. National Library of Medicine,2017)and IFA GESTIS (Gestis Substance Database,2017) for the structurally similar read across substance Dipentene (138-86-3). Acute oral toxicity study was done in rats using test material Dipentene(138-86-3) .50% mortality was observed at dose 5300 mg/kg bw. Hence,LD50 value was considered to be 5300 mg/kg bw,when rats were treated with Dipentene(138-86-3)orally.
In another experimental study conducted by D. L. J. Opdyke (Food and Cosmetics Toxicology ,Volume 12, Issues 5–6, Pages 601-805 (October 1974)) and U.S. National Library of Medicine (Chemidplus Database,U.S. National Library of Medicine,2017) for the structurally similar read across substance Citrus aurantium var. amara(68916-04-1). Acute oral toxicity study was done in rats using test material Citrus aurantium var. amara(68916-04-1).No mortality was observed at dose 5000 mg/kg bw. Hence,LD50 value was considered to be >5000 mg/kg bw,when rats were treated with Citrus aurantium var. amara (68916-04-1)orally.
Also these results are further supported by the experimental study conducted by D. L. J. Opdyke (Food and Cosmetics Toxicology,Volume 14, Supplement, 1976, Pages 877-878) ; U.S. National Library of Medicine (HSDB (Hazardous Substances Data Bank); US national Library of Medicine,2017); Richard J. Lewis (Sax's Dangerous Properties of Industrial Materials, 12th Edition, 5 Volume Set,2012) and U.S. National Library of Medicine (Chemidplus Database,U.S. National Library of Medicine,2017) for the structurally similar read across substance 1-methyl-4(1-methylethylidene) cyclohex-1-ene (586-62-9). Acute oral toxicity study was done in 10 rats per sex per dose using test material1-methyl-4(1-methylethylidene) cyclohex-1-ene(586-62-9) at dose 3000 mg/kg bw,3500 mg/kg bw,4000 mg/kg bw and 5000 mg/kg bw.At dose 3000 mg/kg bw no mortality was observed,at dose 3500 mg/kg bw 1 rat died ,at dose 4000 mg/kg bw 5 rats died and at dose 5000 mg/kg bw 6 rats died.Hence,LD50 value was considered to be 4390 mg/kg bw(95% CI 3750 - 5140 mg/kg),when rats were treated with 1-methyl-4(1-methylethylidene) cyclohex-1-ene(586-62-9)orally.
Thus, based on the above studies and predictions on Black Pepper Oil (8006-82-4) and its structurally similar read across substances, it can be concluded that LD50 value was 5998.58 mg/kg bw.Thus, comparing this value with the criteria of CLPregulation,Black Pepper Oil (8006-82-4) can be “Not classified” for Acute Oral Toxicity.

Acute dermal toxicity study was done in rabbits using test material Black Pepper Oil (8006-82-4).No mortality was observed at dose 5000 mg/kg bw. Hence,LD50 value was considered to be >5000 mg/kg bw,when rabbits were treated with Black Pepper Oil (8006-82-4)by dermal application.
In another experimental study conducted by U.S. National Library of Medicine (Chemidplus Database,U.S. National Library of Medicine,2017)and IFA GESTIS (Gestis Substance Database,2017) for the structurally similar read across substance (+)-Limonene (5989-27-5). In acute dermal toxicity study,rabbits were treated with (+)-Limonene (5989-27-5) in the concentration of 5000 mg/kg bw by dermal application.No mortality was observed in treated rabbits at dose 5000 mg/kg bw.Therefore, LD50 value was considered to be >5000 mg/kg bw,when rabbits were treated with (+)-Limonene (5989-27-5)by dermal application.
In another experimental study conducted by IFA GESTIS (Gestis Substance Database,2017) for the structurally similar read across substance Dipentene (138-86-3). In acute dermal toxicity study,rabbits were treated with Dipentene(138-86-3)in the concentration of 5000 mg/kg bw by dermal application.No mortality was observed in treated rabbits at dose 5000 mg/kg bw.Therefore, LD50 value was considered to be >5000 mg/kg bw,when rabbits were treated with Dipentene(138-86-3)by dermal application.

In acute dermal toxicity study,rabbits were treated with Citrus aurantium var. amara(68916-04-1) in the concentration of 10000 mg/kg bw by dermal application.No mortality was observed in treated rabbits at dose 10000 mg/kg bw.Therefore, LD50 value was considered to be >10000 mg/kg bw,when rabbits were treated with Citrus aurantium var. amara(68916-04-1)by dermal application.
Also these results are further supported by the experimental study conducted by D. L. J.

In acute dermal toxicity study,10 rabbits were treated with 1-methyl-4(1-methylethylidene) cyclohex-1-ene(586-62-9) in the concentration of 5000 mg/kg bw by dermal application for seven days of observation period following exposure.A single 24 hour application of test substance was applied to the clipped abraded abdominal skin of rabbits.Gross necropsies were performed on all animals at study termination. No mortality was observed in treated rabbits at dose 5000 mg/kg bw.No evidence of toxicity from percutaneous absorption of the test substance. Erythema and edema were reported during the first few days of observation, but cleared by the study termination.Therefore, LD50 value was considered to be >5000 mg/kg bw,when rabbits were treated with1-methyl-4(1-methylethylidene) cyclohex-1-ene(586-62-9)by dermal application.
Thus, based on the above studies and predictions on Black Pepper Oil (8006-82-4) and its read across substances, it can be concluded that LD50 value was 2733.84 mg/kg bw.Thus, comparing this value with the criteria of CLP regulation, Black Pepper Oil (8006-82-4) can be “Not classified” for Acute Dermal Toxicity.
Justification for classification or non-classification
Thus, comparing this value with the criteria of CLP regulation, Black Pepper Oil (8006-82-4) can be “Not classified” for Acute Oral and Dermal Toxicity
