Description of key information

Waiver: due to negligible exposure to aquatic organisms and no adverse effects to invertebrates are expected. Therefore, no further testing is needed.

Key value for chemical safety assessment

Additional information

There are no reliable (Klimisch 1 or 2) long-term toxicity studies with invertebrates available with HQEE. However, a waiver is applied for this endpoint.

 

Under Column 2 of the Annex IX of Regulation (EC) No 1907/2006 the specific rules for adaptation from Column 1 are that the long-term toxicity testing shall be proposed by the registrant if the chemical safety assessment according to Annex I indicates the need to investigate further the effects on invertebrates. It is proposed that testing is waived as exposure potential is negligible. The substance has a very low log octanol-water partition coefficient (log Kow) of 0.41 at a neutral pH. The low log Kow indicates the substance has a low adsorptive and bioaccumulative potential. There is negligible exposure to aqueous process streams during downstream use and hence also negligible emission to a sewage treatment plant. It is proposed that testing is waived as exposure is negligible.

 

The short-term invertebrate study reported in this assessment provides evidence of the low toxicity to invertebrates with lethal concentrations (LC50) greater than 100.2 mg/L. 

 

Therefore, under such conditions and due to negligible exposure to aquatic organisms and no adverse effects to invertebrates are expected. Therefore, no further testing is needed.
