12.2 Persistence and degradability
Further details:
Information about Methacrylic acid, monoester with propane-1,2-diol
Biodegradation: > 81 %/28 d. (OECD 301C) (readily biodegradable (according to OECD criteria))
Information about Acrylic acid
Biodegradation: 80 %/28 d. (OECD 301D) (readily biodegradable (according to OECD criteria))
Information about Cumene hydroperoxide
Biodegradation: 3 %/28 d. (OECD 301B) (not readily biodegradable (according to OECD criteria))
12.3 Bioaccumulative potential
Information about Acrylic acid: Partition coefficient: n-octanol/water (log pOW) / Method: 0.35
Information about Cumene hydroperoxide: Partition coefficient: n-octanol/water (log pOW) / Method: 2.16
Partition coefficient: n-octanol/water:
0.35 log P(o/w) (Acrylic acid)
Based on the n-octanol/water partition coefficient accumulation in organisms is not expected.
0.97 log P(o/w) (Methacrylic acid, monoester with propane-1,2-diol)
Based on the n-octanol/water partition coefficient accumulation in organisms is not expected.
2.16 (Cumene hydroperoxide)
Based on the n-octanol/water partition coefficient accumulation in organisms is not expected.
