Additional information

Alkalised cocoa powder is a UVCB that is the result of a manufacturing process including the alkalisation of cocoa powder with potassium carbonate and/or sodium hydroxide. Neither alkalisation substance is present in the final product. Since the above alkalization step is taking place prior to the roasting step, ACP is considered to be the same as the EINECS-listed substance "Cocoa, powder, alkalized" with EC number 305-748-4 and CAS number 95009-22-6.

Table 2 of the CSR showed a comparison of the constituents of alkalised cocoa powder and cocoa powder and the compositions are essentially similar.

Based on the similar structures and compositions, as well as the rapid biodegradation and the toxicity data discussed in this section, cocoa powder is an appropriate read-across substance for alkalised cocoa powder. Therefore, the data presented in this IUCLID dossier for cocoa powder can be used to directly read-across to alkalised cocoa powder with respect to ecotoxicological hazard.

Conclusion on classification

Asumming that the endpoints expressed in loading rate WAF are acceptable ( as the TOC measurements cannot express actual concentrations) and are used for classification purposes and that cocoa powder is really biodegradable, then the substance is not classified as 'dangerous for the environment' under DSD/DPD and 'hazardous to the aquatic environment' under CLP.
