Applicant's summary and conclusion
- Conclusions:
- The substance 1, 4-bis(mesitylamino)anthraquinone is not persistent in air medium as the half life period of 1, 4-bis(mesitylamino)anthraquinone in air is only 0.079 days which does not exceeds the criteria of 2 days.
- Executive summary:
The atmospheric oxidation half-life of 1, 4-bis(mesitylamino)anthraquinone was estimated using the level III multimedia model. It was estimated that the substance is not persistent in air medium as the half life period of 1, 4-bis(mesitylamino)anthraquinone in air is only 0.079 days. This indicates that 1, 4-bis(mesitylamino)anthraquinone is rapidly phototransformed in air.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
