Additional information

Conclusion on classification

Degradation

Biodegradation: readily biodegradable: 91% (CO2 evolution) of isononyl isononanoate after 28 d (OECD 301B)

Bioaccumulation

(Q)SAR: Bioaccumulation is assumed to be low (BCF: 113.1 - 484.3 L/kg)

Aquatic acute toxicity

96 h, LL50 (Danio rerio): > 100 mg/L (nominal; no observed toxicological effects up to the water solubility limit based on mortality)

Aquatic chronic toxicity

21 d, NOELR (Daphnia magna): ≥ 100 mg/L (nominal; OECD 211; no observed toxicological effects up to the water solubility limit based on reproduction)

CLP

Based on the data above, isononyl isononanoate is considered to be rapidly degradable. No acute aquatic toxicity was observed up to the water solubility limit (< 0.05 mg/L) for fish. Valid chronic data are available with a NOELR (21 d) ≥ 100 mg/L (i.e. above the limit of water solubility) for Daphnia magna. Therefore, isononyl isononanoate does not need to be classified and labelled as environmental hazard according to the 2nd ATP of the Regulation (EC) No. 1272/2008 (CLP).

DSD

The substance is poorly soluble in water and no effects occurred up to its solubility limit in an acute test for fish and a chronic test with Daphnia magna (no immobilization observed up to the limit of water solubility). Therefore, isononyl isononanoate does not need to be classified and labelled as environmental hazardous according to Directive 67/548/EEC.
