The results were re-evaluated in a pathology peer review and it was concluded that this linear focal retinopathy was similar to the spontaneous incidence of focal linear degeneration of around 3 % in this rat strain.

The SCCS favours a toxicokinetics-based Margin of Safety. In a new study human systemic exposure was determined following application of an oxidative hair colouring formulation containing 1.5 and 4.0% toluene-2,5-diamine, respectively. The mean plasma AUC(0-∞) values were 1241 ng eq-hr/mL and 3553 ng eq-hr/mL for the low and high concentration mixtures, respectively. These values were compared to the rat mean AUC(0-∞) of 46.3 µg eq-hr/mL (see Ref. 14) at the NOAEL dose of 10 mg/kg bw/day established in the 91 day oral toxicity study. The toxicokinetics-based Margin of Safety was 37.3 and 13.0, respectively.
