- Justification:
Persistence Assessment
Sodium percarbonate does not have a half-life greater than those specified in Annex XIII of the REACH Regulation in any of the listed environmental compartments. According to Annex XIII, sodium percarbonate is not persistent. It rapidly dissociates into hydrogen peroxide and sodium carbonate in the environment.
Bioaccumulation Assessment
Sodium percarbonate dissociates in water into sodium carbonate and hydrogen peroxide. It does not have a bioconcentration factor and thus is not bioaccumulative according to the criteria of Annex XIII.
Sodium carbonate in water will dissociate into sodium and carbonate and both ions will not accumulate in living tissue (OECD 2002). Hydrogen peroxide is a reactive and short-lived polar substance and no bioaccumulation is expected. Also its estimated log Kow of -1.57 indicates negligible potential of bioconcentration in aquatic and/or terrestrial organisms (European Commission 2003).
Toxicity Assessment
According to the criteria of Annex XIII, sodium percarbonate is not a toxic substance.
