Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Phototransformation in air
After evaporation or exposure to air, the substance will be rapidly degraded by photochemical processes.
Hydrolysis
According to two hydrolysis studies, the substance is hydrolytically stable. In addition, the substance is readily biodegradable.
Phototransformation in water
The substance is photolytically stable in water.
Phototransformation in soil
The substance is photolytically stable in soil.
Biodegradation in water: screening tests
The substance is readily biodegradable according to OECD.
Simulation testing on ultimate degradation in surface water
Simulation testing on ultimate degradation in surface water is waived based upon REACH Annex IX Section 9.2.1.2 column 2 as 1) the substance is readily biodegradable.
Sediment simulation testing
Sediment simulation testing is waived based upon REACH Annex IX Section 9.2.1.4 column 2 as 1) the substance is readily biodegradable.
Soil simulation testing
A biodegradation report run to EPA on surfadone 14C-LP-100 in soil resulted a half-life of 1.3 days.
Adsorption / desorption
Adsorption of the substance to the solid soil phase is not expected under environmentally relevant conditions.
Henry's Law constant
From the water surface the substance will not evaporate into the atmosphere under environmentally relevant conditions.
Environmental distribution
Over time, the substance will preferentially distribute into the compartments water (30.7%), sediment (34.7%), and soil (34.3%).
Biodegradation in water: There are two studies availiable regarding biodegradation in water. Both studies show that the substance is readily biodegradable.
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.
