Additional information

Acute oral:

C.I. Pigment Violet 55 was administered by oral gavage to two subsequent groups of three females Wistar rats at 2000 mg/kg bw according to OECD 423 guideline and GLP Principles.

No mortality occurred. Hunched posture was noted in all animals and had resolved within 2 or 4 hours post-treatment. No effect on body weight gain was observed. No macroscopic abnormalities were found. The oral LD50 value of C.I. Pigment Violet 55 was established to exceed 2000 mg/kg bw.


Justification for selection of acute toxicity – oral endpoint
One key study is available and as well as read across to C.I. Pigment violet 54 and C.I. Pigment Red 202

Justification for classification or non-classification

Based on the results mentioned above, C.I. Pigment Violet 55 does not have to be classified and has no obligatory labelling requirement for acute oral, dermal or inhalation toxicity in accordance with Regulation EC No. 1272/2008.
