Description of key information
The oral LD50 of RD14153 is greater than 2000 mg/kg.
The dermal LD50 of RD 14153 is greater than 2000 mg/kg of body weight in rats.
A study for acute inhalation toxicity does not need to be conducted because inhalation is not anticipated to be a significant route of exposure based on the low vapour pressure and physical form of the substance (waxy solid, flakes).
Key value for chemical safety assessment
Acute toxicity: via oral route

- Executive summary:
The study was designed to examine the potential toxicity of RD14153 when administered orally to Sprague-Dawley rats. the study was conducted according to the guidelines OECD 425 and OPPTS 870.1100.
Initially a single female rat was dosed orally with RD14153 at 2000 mg.kg bodyweight. The animal survived and subsequently 4 further femae rats were dosed at 2000 mg/kg bodyweight.The rats were observed at 15 mins 1, 2 and hours post dose and once daily for toxicity and pharmacological effects. All animals were observed twice daily for mortality. Bodyweights were recorded immediately pre-test, weekly and at termination.All animals were examined for gross pathology.
All animals survived a single dose of 2000 mg/kg bodyweight. there were no ablnormal physical signs, all five rats gained in bodyweight and gross pathology of all animals revealed no observable abnormalities.
The oral LD50 of RD14153 is greater than 2000 mg/kg.

Acute toxicity: via inhalation route
Link to relevant study records
- Endpoint:
- acute toxicity: inhalation
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because exposure of humans via inhalation is not likely taking into account the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles or droplets of an inhalable size

Additional information
In a study to determine the acute toxicity of the substance via oral administration all animals survived a single dose of 2000 mg/kg bodyweight. there were no ablnormal physical signs, all five rats gained in bodyweight and gross pathology of all animals revealed no observable abnormalities.
In a study to determine the acute toxicity of the substance via oral administration All animals survived following a 24 -hour dermal exposure at 2000 mg/kg. No abnormal physical signs were observed. All ten animals gained body weight by study termination. The gross necropsy revealed no observable abnormalities. Immediately following unwrapping, erythema and edema were absent to very slight. By Day 14, erythema and edema were absent.
Justification for classification or non-classification
The substance has been tested for acute oral toxicity and the LD50 was determined to be greater than 2000 mg/kg.
The substance has been tested for acute dermal toxicity and the LD50 was determined to be greater than 2000 mg/kg.
In accordance with the classifciation criteria described in CLP Regulation 1272/2008 the substance is not classified for acute oral or acute dermal toxicity.
