The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

ZDDPs are expected to have low oral and dermal absorption based on modeling, toxicity data, and physiochemical properties. Upon ingestion, ZDDPs are expected to be transformed in the GI fluid to the corresponding alkyl dithiophosphate ester (dissociated from the Zn). Any alkyl dithiophosphate ester that is bioavailable will undergo metabolism consistently across the category, ultimately being metabolized to the corresponding starting alkyl alcohol followed by typical alcohol metabolism.
