Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Hydroxypropyl methacrylate is readily biodegradable and has a low potential to bioaccumulate in organisms or to adsorb to soil or sediment.
Additional information
Hydroxypropyl methacrylate has high water solubility (130 g/L at 25 deg C), a low vapor pressure (0.11 hPa at 20 deg C), and low log Kow (0.97 at 20 deg C). The substance has a low potential for adsorption to soil or sediments or bioaccumulation in aquatic organisms, and a low potential to volatilize from water or soil to the atmosphere. The substance is hydrolytically stable in water under acidic conditions, and the rate of hydrolysis increases as the pH is increased. The compound meets the criteria of ready biodegradability in an OECD 301C and 301E tests. Upon release to the atmosphere the substance will react with hydroxyl radicals with a predicted half-life of 0.6 days.
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.
