Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 82.2% (O2 consumption) after 28 d (OECD 301 F)

Bioaccumulation

(Q)SAR:BCF: 45.78 - 61.6 L/kg (BCFBAF v3.01)

Aquatic acute toxicity

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

48 h, EL50 (Daphnia magna): > 25 mg/L (nominal)

72 h, ErL50 (Selenastrum capricornutum): 62.58 mg/L (nominal; based on growth rate)

 

Aquatic chronic toxicity

Fish: no data

21 d, NOELR (Daphnia magna): 0.11 mg/L (measured, initial) based on reproduction

Aquatic algae: no data

 

CLP

Based on the data above, the acute aquatic toxicity E(L)L50 loading rates are > 1 mg/L. Therefore, Propanoic acid, 2-hydroxy-, C12-13-branched-alkyl esters does not need to be classified and labelled as acute environmental hazard according to the 2nd ATP of the Regulation (EC) No. 1272/2008 (CLP). Based on the data above, Propanoic acid, 2-hydroxy-, C12-13-branched-alkyl esters is considered to be rapidly degradable and has a low potential for bioaccumulation. Valid chronic toxicity data are available for aquatic invertebrates with a NOELR (21 d) of 0.11 mg/L (measured, initial). Therefore, the substance needs to be classified and labeled as long-term aquatic hazard Chronic Category 3 (H412) according to the 2nd ATP of the Regulation (EC) No. 1272/2008 (CLP).

 

DSD

Based on the data above, Propanoic acid, 2-hydroxy-, C12-13-branched-alkyl esters is considered to be rapidly degradable and has a low potential for bioaccumulation. The acute toxicity L(E)C(L) 50 values are > 1 mg/L for fish, aquatic invertebrates and algae. Therefore, Propanoic acid, 2-hydroxy-, C12-13-branched-alkyl esters does not need to be classified and labelled as environmental hazardous according to Directive 67/548/EEC.
