Description of key information

No long-term toxicity tests were available with aquatic invertebrates exposed to DPnP.

Key value for chemical safety assessment

Additional information

Dipropylene glycol n propyl ether (DPnP) is classified as readily biodegradable with a low potential for bioaccumulation and has an expected low potential for adsorption with a log Kow <1.  According to REACH Annex IX requirements, long-term toxicity testing shall only be considered when the chemical safety assessment indicates the need for further investigations.  The chemical safety assessment according to Annex I does not indicate a need to investigate any other effects since DPnP has no hazard classification based on available toxicity data.  Therefore long-term toxicity testing is waived for DPnP.
