- Executive summary:
This data is being read across from the source study that tested Resin acids and Rosin acids, hydrogenated, methyl esters based on category read across that is explained in the category justification document attached in Section 13 of the dossier.
In an acute dermal toxity study, a single treatment of 2000 mg/kg/bw of Resin acid and rosin acid, hydrogenated methyl ester was applied to clipped skin on the dorsal trunk of 10 Sprague Dawley rats (5 male and 5 female) for 24 hrs under semi-occlusion. Under the conditions of the study, no mortality occurred and no dermal reactions or systemic clinical signs observed. Body weight gain was normal. A gross pathogical examination showed no treatment- related changes. In conclusion, the acute dermal LD50 of Resin acids and rosin acids, hydrogenated methyl ester was >2000 mg/kg/bw.
