Chem Name : 2-Propenoic acid, 2-methyl-, 2-hydroxyethyl ester
Molecular Wt: 130.14
Henry's LC : 2.16e-007 atm-m3/mole (Henry database)

Results and discussion
Percent distribution in media
- Other distribution results:
- The distribution modelling (Mackay level III fugacity modelling) indicates that when 2-hydroxyethyl methacrylate is released to water, most of the substance will remain in water. If released to air, most of the substance will be transported to water and soil. If released to soil, most of the substance will remain in soil with a portion transported to water.

Applicant's summary and conclusion
- Conclusions:
- Using a valid modeling method, if hydroxyethyl methacrylate is released into air, it mainly partitions into soil and to a lesser degree into water; if it is released into water, it mainly remains in the water. If released to soil, most of the substance will remain in soil with a portion transported to water.
- Executive summary:
Using a valid modeling method, if hydroxyethyl methacrylate is released into air, it mainly partitions into soil and to a lesser degree into water; if it is released into water, it mainly remains in the water. If released to soil, most of the substance will remain in soil with a portion transported to water.
