Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A read across from Zinc methacrylate has been performed in order to determine the dust explosivity of hydroxy(2-methylprop-2-enoato-O)zinc.
As the particle size of Zinc methacrylate is very close to that of hydroxy(2-methylprop-2-enoato-O)zinc, we could conclude that the result should be also positive. In the study of zinc methacrylate, the measured overpressure relative to the initial pressure (pm) is in three tests significantly above 0.3Zinc methacrylate has been identified as dust explosible and therefore hydroxy(2-methylprop-2-enoato-O)zinc could be considered also as dust explosive.
Additional information
A read across from Zinc methacrylate has been performed in order to determine the dust explosivity of hydroxy(2-methylprop-2-enoato-O)zinc.
As the particle size of Zinc methacrylate is very close to that of hydroxy(2-methylprop-2-enoato-O)zinc, we could conclude that the result should be also positive.
In the study of zinc methacrylate, the measured overpressure relative to the initial pressure (pm) is in three tests significantly above 0.3. Zinc methacrylate has been identified as dust explosible and therefore hydroxy(2-methylprop-2-enoato-O)zinc could be considered also as dust explosive.
Additionals data explosion were performed for the zinc methacrylate to measure:
-Maximum Explosion Pressure (Pmax): 7.4 bar
-Max.Rate of pressure Rise (dP/dt)max: 519 bar/s
-Kst value: 141 bar.m/s : The relationship between Kst value and the physical severity of the dust explosion is weak explosion
-Minimum Ignition Energy:10-25mJ
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.
