Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Conclusion on classification

Degradation

Biodegradation: readily biodegradable: 86% (O2 consumption) of isononanoic acid, C16-18 alkyl esters after 30 d (OECD 301D)

 

Bioaccumulation

Expert statement: Bioaccumulation is assumed to be low.  

 

Aquatic acute toxicity

96 h, LC50 (Brachydanio rerio): > 10000 mg/L (nominal; No observed toxicological effects up to the water solubility limit)

48 h, EC50 (aquatic invertebrates): no data

72 h, ErL50 (Desmodesmus subspicatus): > 100 mg/L (nominal; No observed toxicological effects up to the water solubility limit based on growth rate)

 

Aquatic chronic toxicity

fish: no data

21 d, NOELR (Daphnia magna): ≥ 10 mg/L (nominal; No observed toxicological effects on reproduction up to the water solubility limit)

72 h, NOELR (Desmodesmus subspicatus): ≥ 100 mg/L (nominal; No observed toxicological effects up to the water solubility limit based on growth rate)

 

CLP

Based on the data above, isononanoic acid, C16-18 alkyl esters is considered to be rapidly degradable. No acute aquatic toxicity was observed up to the water solubility limit (< 0.05 mg/L) for fish and algae. Valid chronic data are available with a NOELR (72 h) ≥ 100 mg/L (i.e. above the limit of water solubility) for Desmodesmus subspicatus and no effects on reproduction of Daphnia magna up to the water solubility limit (OECD 211). Therefore, isononanoic acid, C16-18 alkyl esters 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 acute tests for fish and algae. Therefore, isononanoic acid, C16-18 alkyl esters does not need to be classified and labelled as environmental hazardous according to Directive 67/548/EEC.
