- Conclusions:
- Under the conditions of this study, the test article, Tetraesters of pentaerythritol with 2- methylpropanoic acid and 3,5,5-trimethyl-hexanoic acid, was considered to have no significant acute toxic risk in respect of its acute oral toxicity and did not meet the criteria for classification under Regulation (EC) No 1272/2008 on classification, labelling and packaging (CLP) of substances and mixtures.
- Executive summary:
OECD 423 (2012) - In an acute oral toxicity study, a group of fasted, 8-12 week old female, nulliparous Crl:CD’SD’ rats were given a single oral dose of Tetraesters of pentaerythritol with 2-methylpropanoic acid and 3,5,5-trimethyl-hexanoic acid at a single dose rate of 2000 mg/kg bw (limit test) and observed for 14 days.
In the absence of mortality during the observation period, the oral LD50 was estimated to be greater than 2000 mg/kg bw.
In addition, there were no treatment related clinical signs, necropsy findings or changes in body weight observed in any of the individuals.
Tetraesters of pentaerythritol with 2-methylpropanoic acid and 3,5,5-trimethyl-hexanoic acid did not meet the criteria for classification according to Regulation (EC) No. 1272/2008 on the Classification, Labelling and Packaging of Substances and Mixture.

Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed
- Quality of whole database:
- The study was conducted in accordance with International guidelines and in accordance with GLP. All guideline validity criteria were met. The study was sufficient to conclude on the acute oral toxicity endpoint.
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
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
The substance meets the Annex VIII, Section 8.5.2, Column 2 criteria as the vapour pressure is 2.0E-04 Pa. The use pattern for the substance will not present situations where exposure to aerosols, particles or droplets of an inhalable size is relevant.

Additional information
Acute Oral Toxicity
OECD 423 (2012) - In an acute oral toxicity study, a group of fasted, 8-12 week old female, nulliparous Crl:CD’SD’ rats were given a single oral dose of Tetraesters of pentaerythritol with 2-methylpropanoic acid and 3,5,5-trimethyl-hexanoic acid at a single dose rate of 2000 mg/kg bw (limit test) and observed for 14 days.
In the absence of mortality during the observation period, the oral LD50 was estimated to be greater than 2000 mg/kg bw.
In addition, there were no treatment related clinical signs, necropsy findings or changes in body weight observed in any of the individuals.
Acute Inhalation Toxicity
Study waiver - The substance meets the Annex VIII, Section 8.5.2, Column 2 criteria as the vapour pressure is 2.0E-04 Pa. The use pattern for the substance will not present situations where exposure to aerosols, particles or droplets of an inhalable size is relevant. Therefore an acute inhalation toxicity test does not need to be conducted.
Acute Dermal Toxicity
OECD 402 (2012) - In an acute dermal toxicity study, a group of 8-12 week old male (5 individuals) and female (5 individuals) (nulliparous) Crl:CD’SD’ rats were exposed to a single dermal application of Tetraesters of pentaerythritol with 2- methylpropanoic acid and 3,5,5-trimethyl-hexanoic acid for 24 hours at a single dose rate of 2000 mg/kg bw (limit test).The test item was applied undiluted to a 50 x 50 mm contact area, equivalent to approximately 10 % of the body surface. After 24-hour exposure, the test site was cleaned with warm water and observations recorded for 14 days.
In the absence of mortality during the observation period, the oral LD50was estimated to be greater than 2000 mg/kg bw.
In addition, there were no treatment related clinical signs, necropsy findings or changes in body weight observed in any of the individuals.
Justification for classification or non-classification
The substance does not meet the criteria for classification in accordance with Regulation (EC) No 1272/2008 (CLP).
