Additional information - General Population
No DNELs have been derived for general population as exposure does not occur during the lifecycle of the substance.
The substance is not used by consumers or professionals and only has manufacture, formulation and industrial uses.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
