Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information

SFL is primarily composed of inorganic substances (the major constituent is calcium carbonate, along with silicon dioxide and a small amount of other inorganic salts) and therefore does not undergo biodegradation i.e. microbial degradation to carbon dioxide and water. The inorganic portion will be degraded in the environment by means other than biodegradation. The remainder of SFL is composed of organic plant material which is naturally present in the environment. Although SFL itself is not readily biodegradable (Degussa, 2007), the organic portion will undergo ultimate degradation in surface water and sediment. The fact that the organic plant material is naturally occurring and non-toxic to the environment means that its presence and degradation would not lead to any disruption of the natural environmental processes.
