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.

Description of key information

Additional information

MPP has been tested and found to be not readily biodegradable. However MPP is not expected to bioaccumulate due to its low partition coefficient. The adsorption coefficient indicates that the notified chemical may be mobile in soils. MPP is used as an additive (fire retardant) in polymers and is largely expected to be trapped within the inert polymer matrix of polymer pellets or finished articles and in this form is not expected to leach or to be bioavailable. In landfill, the MPP is expected to be released from the polymer matrix over time and ultimately degrade to form water and oxides of carbon, nitrogen and phosphorous.
