Remarks:
Criteria used for interpretation of results: EU
Conclusions:
The LD50 of Rosin, fumarated, reaction product with glycerol and pentaerythritol is greater than 2000 mg/kg bw by the oral route in the rat.

According to the criteria for classification, packaging and labelling of dangerous substances and preparations in accordance with EEC Directives 67/548, 2001/59 and 99/45, the test item of Rosin, fumarated, reaction product with glycerol and pentaerythritol cannot be classified because it cannot be determined whether the LC50 falls in Category IV (< 2000 mg/kg) or outside of the category.

In accordance with the Globally Harmonised System (Regulation (EC) No. 1272/2008) the test item cannot be classified because it cannot be determined whether the LC50 falls in Category V (< 5000 mg/kg) or outside of the category.
Executive summary:

This data is being read across from the source study that tested Rosin, fumarated, reaction products with glycerol and pentaerythritol based on category read across that is explained in the category justification document attached in Section 13 of the dossier.

The acute oral toxicity of rosin, fumarated, reaction product with glycerol and pentaerythritol was evaluated in a study conducted according to OECD Guideline 423. Six female rats were each administered a single dose of 2000 mg/kg bw of the test substance by gavage. All animals survived to study termination. All animals gained weight normally and there were no signs of systemic toxicity. The acute oral LD50 in this study was >2000 mg/kg bw for female rats.
