Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
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
Mecoprop-P n-octyl ester hydrolyses rapidly in natural water. Therefore, the hydrolysis product Mecoprop-P acid (MCPP-P acid) was used for further risk assessment of Mecoprop-P n-octyl ester in the environment.
Mecoprop-P acid (MCPP-P acid) has a low sorption potential to soil and sediment, and a moderate migration potential to groundwater.
The Henrys law constant of Mecoprop-P acid (MCPP-P acid) is 5.74E-05 Pa*m3/mol. Therefore, Mecoprop-P acid (MCPP-P acid) is considered nonvolatile from the aqueous phase, and no potential for long-range transport is given.
The distribution of Mecoprop-P acid (MCPP-P acid) in a "unit world" was calculated according to the Mackay fugacity model level I based on the physico-chemical properties. The main target compartment for Mecoprop-P acid (MCPP-P acid) is water with 99.98 %, followed by soil and sediment with 0.008 % and air with 0.002 %, respectively.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
