Justification for selection of acute toxicity – oral endpoint
guidance test with GLP compliance
Justification for selection of acute toxicity – dermal endpoint
guidance test with GLP compliance
Justification for classification or non-classification
Based on the results of oral and dermal toxicity tests of the substance, it is not classified as per EU CLP (Regulation (EC) No 1272/2008) regulation or DSD (Directive 67/548/EEC) for acute toxicity. Also, due to lack of signs for systemic toxicity, classification for Specific Target Organ Toxicity, Single Exposure (STOT SE) according to CLP or for irreversible effects following single exposure according to DSD is not required.
