Additional information
Conclusion on classification
The substance is an organic substance with a log Kow of 2.3.
Acute toxicity values
The following toxicity values are available for the substance.
Fish Acute:
QSAR estimation based on Mode of Action 1: 96h-LC50= 208 mg/L
Aquatic invertebrates:
Daphnia magna (OECD 202) 48h-EC50 > 100 mg/L
Algae:
QSAR estimation based on Mode of Action 1: 72h-EC50= 181 mg/L
The lowest acute aquatic toxicity value based on available data is higher than 1.0 mg/L.
No chronic toxicity values are available for the substance.
Biodegradation
The Ready Biodegradability of the substance was first determined by the Manometric Respirometry Test, following Guideline OECD 301 F and performed according to GLP. The tested substance underwent 49% biodegradation after 28 days (77% after 56 days and 76% after 70 days) in the test conditions. The 10-day window criterion was not fulfilled (14% biodegradation at day 6 and 41% at day 16). The tested substance did not inhibit the intrinsic respiration of the inoculum at the test concentration and was therefore considered to be non-toxic to the incoculum at the test concentration. Thus, the test item should be considered as not readily biodegradable according to this test. However, based on these results it should be considered as inherently and ultimately biodegradable.
A second study was conducted according to Guideline OECD 301D. Test item 7-METHOXY-3,7-DIMETHYLOCTAN-2-OL MULTICONSTITUENT was biodegraded by 10% at day 28 in the Closed Bottle test and by 45% at day 55, confirming that the substance cannot be considered as readily biodegradable. However, the results at 55 days are not reliable as the difference between both replicates for the test substance degradation is higher than 20% (35%).
Bioaccumulation potential
Experimental information on bioaccumulation potential of the submission substance is not available.
CLP Classification proposal
Acute aquatic hazard: Not classified. M-Factor: not relevant.
Reasoning: lowest E(L) C50 higher than 1.0 mg/L.
Chronic aquatic hazard: Not classified. M-Factor: not relevant.
Reasoning: lowest acute E(L) C50 value higher than 100 mg/L and Log Kow < 4.
