Description of key information
28-d repeated dose testing is not required as it is suggested to perform a long-term (90-d) repeated dose toxicity (with the Read-Across substance charcoal) instead.
Key value for chemical safety assessment
Additional information
28-d repeated dose testing of coconut shell charcoal is not required as it is suggested to perform a long-term (90-d) repeated dose toxicity study by inhalative route of administration instead (with the Read-Across substance charcoal).
As some exposure to inhalable coconut shell charcoal particles (< 100 µm) in particular during manufacturing and (re) packing cannot be ruled out, a study investigating the sub-chronic toxicity of charcoal(the Read-Across substance)is recommended. To this end, in accordance with REACH Regulation (EC) No. 1907/2006, Annex IX, 8.6.2, a 90-d repeated dose inhalation study should be performed. Alternatively, the 90-day repeated dose study might be replaced by a chronic in vitro CULTEX study using epithelial cell lines, such as alveolar cells type (A549) or bronchial cells 16 HBE14o- (Cultex Laboratories Ltd, Hannover Germany). In each study, as in the acute inhalation toxicity study already performed (see section 5.2.1.2), charcoal particles with average sizes of ≈ 4 µm should be used.Justification for classification or non-classification
