Additional information
Justification for classification or non-classification
An acute oral toxicity study was conducted (Envigo Research Limited, 2016, Study 41501807) to assess the toxicity of Dailube-IS following a single oral administration. The study was conducted in accordance with OECD 420 test guidelines and EU Method B.1 bis, and in compliance with GLP.
In accordance with the acute toxic class method, four fasted female Wistar rats were administered a single dose of 2000 mg/kg Dailube-IS by oral gavage.
There were no deaths at this dose level as well as no signs of systemic toxicity.
It was concluded that the acute median lethal dose in rats following oral administration of Dailube-IS was greater than 2000 mg/kg.
An acute dermal toxicity study was conducted (Envigo Research Limited, 2017, Study BG62LF) to assess the toxicity of Dailube-IS following a single dermal administration. The study was conducted in accordance with OECD test guideline 402 and EU Method B.3, and in compliance with GLP.
Five male and five female Wistar rats were administered a single dermal dose of 2000 mg/kg; the application site was wiped 24 hours after initial administration, then the animals were observed for 14 days.
There were no deaths during the observation period, no systematic response to treatment was observed, and no abnormalities were noted at necroscopy.
It was concluded that the acute median lethal dose in rats following dermal administration of Dailube-IS was greater than 2000 mg/kg.
No acute inhalation toxicity study was conducted as the available acute oral and dermal studies do not suggest acute toxicity via inhalation route.
The acute oral LD50 of Dailube-IS was determined to be greater 2000 mg/kg, on this basis Dailube-IS is not classified for acute dermal toxicity under the CLP Regulation.
The acute dermal LD50 of Dailube-IS was found to be greater than 2000 mg/kg; on this basis Dailube-IS is not classified for acute dermal toxicity under the CLP Regulation.
No test data is available as a basis to classify Dailube-IS for acute inhaled toxicity.
