Esters and salts in April 2024

[Mike Dewhirst]

Esters and salts which have components (parents) on the High Hazard list are themselves considered to be High Hazard.

Each of the health properties now have specifically listed esters which have specific exceptions due to certain properties which now need to be considered during categorisation.

These sections in the Guidelines for health properties are:

6.3.2 Carcinogenicity
6.4.2 Reproductive toxicity
6.5.2 Developmental toxicity
6.6.2 Adverse effects mediated by an endocrine mode of action
6.7.2 Genetic toxicity

and environment properties ...

6.25.2 Adverse effects mediated by an endocrine mode of action
6.26.2 PBT (reference to esters and salts removed - no listed ones)
6.27.2 Very toxic to any aquatic life (ditto PBT)
6.28.2 Persistent and bioaccumulative (ditto PBT)

These chemicals probably need their own ester/salt table entries. It would be preferable to centralise them in the main Index. Some more research is required.
