Biodegredability of substances (E34)

Criteria question

[no modifications]

Does the standard include criteria on biodegradability of substances?


[no modifications]

This aspect can be covered e.g. by recognized test methods (e.g. OECD or REACH methods). E.g. per-/polyfluorinated chemicals have a low biodegradability.

Degree of Intensity (DoI)

1. Claim biodegradability of substances/preparations for some applications

2. Claim biodegradability of Substances/preparations for all applications

This criterion is a newly proposed minimum criterion.

"Biodegradation" is an important parameter for determining an ecological impact. If a substance is not biodegradable, it will persist and, if further emitted, accumulate in the environment.

@ Degree of intensitiy, 1. Claim biodegradability of substances/preparations for some applications

Please add:
at least for fabric softeners, complexing agents and surfactants.

Thanks for your proposal! Could you provide an explanation why the mentioned applications should be covered as a minimum?

This check point is lacking definitions. Even cotton and some other biopolymers can be understood as being not biodegradable under certain testing conditions.

Thanks four you comment. We should specify in the guidance, which possible applications are meant/which substanced should ideally be biodegradable.
