Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

Key parameters for environmental classification

1) Biodegradation in water: Readily biodegradable, 79% biodegradation in 28 days (OECD 301B)

2) Bioaccumulation: No significant bioaccumulation in biota is expected for this substance (see IUCLID section 5.3 for further information).

3) a) Acute aquatic toxicity:

96 h, LC50 (Danio rerio): > 100 mg/L (nominal; No effects up to the limit of water solubility (WS < 0.15 mg/L))

48 h, EC50 (Daphnia magna): > 1 < 10 mg/L (nominal, WAF); EC50 = 5.05 mg/L (statistical analysis of the raw data)

72 h, EC50 (Pseudokirchneriella subcapitata): > 320 mg/L (nominal; No effects up to the limit of water solubility (WS < 0.15 mg/L) based on growth rate)

 

b) Chronic aquatic toxicity:

72 h, EC10 (Pseudokirchneriella subcapitata): > 320 mg/L (nominal; No effects up to the limit of water solubility (WS < 0.15 mg/L) based on growth rate)

21 d, NOELR (Daphnia magna): 4 mg/L (nominal; WAF)

 

Classification justification according to CLP

Based on the data above, 1,2,3-propanetriol, homopolymer, diisooctadecanoate (CAS 63705-03-3) is considered to be rapidly degradable and has low potential for bioaccumulation. The short-term aquatic toxicity L(E)C50 values are above 1 mg/L for fish, invertebrates and algae. Valid chronic toxicity data are available for invertebrates and algae – the lowest NOEC is 4 mg/L for aquatic invertebrates. Thus, 1,2,3 -propanetriol, homopolymer, diisooctadecanoate (CAS 63705-03-3) does not need to be classified and labelled according to the 2nd ATP of Regulation (EC) No. 1272/2008 (CLP).

 

Classification justification according to DSD

Based on the available data, 1,2,3-propanetriol, homopolymer, diisooctadecanoate (CAS 63705-03-3) is considered to be rapidly degradable and has a low potential for bioaccumulation. The short-term aquatic toxicity L(E)C50 values are above 1 mg/L for fish, invertebrates and algae. Thus, the substance does not need to be classified and labeled as environmental hazard according to Directive 67/548/EEC.
