Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

According to Article 13 of Regulation (EC) No. 1907/2006 "General Requirements for Generation of Information on Intrinsic Properties of substances", information on intrinsic properties of substances may be generated by means other than tests e.g. from information from structurally related substances (grouping or read-across), provided that conditions set out in Annex XI are met.

Annex XI, "General rules for adaptation of this standard testing regime set out in Annexes VII to X” states that “substances whose physicochemical, toxicological and ecotoxicological properties are likely to be similar or follow a regular pattern as a result of structural similarity may be considered as a group, or ‘category’ of substances. This avoids the need to test every substance for every endpoint”.

 

Since the group concept is applied to the members of the Glycerides category, data will be generated from a representative category member to avoid unnecessary animal testing. Additionally, once the group concept is applied, substances will be classified and labelled on this basis.

Classification related key information

 

Biodegradation in water: screening tests:   76.5% in 28 days (read-across)(OECD 301B).

 

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

Acute toxicity:

Fish:   

LC50 (48 h)(Leuciscus idus): > 10000 mg/L (nominal)(DIN 38412/15).

Aquatic invertebrates:

EL50 (48 h)(Daphnia magna): > 100 mg/L (nominal, loading rate)(OECD 202).

Algae:

ErL50 (72 h)(Desmodesmus subspicatus): > 320 mg/L (nominal, loading rate)(OECD 201).

 

Chronic toxicity:

Aquatic invertebrates:

NOELR (21 d)(Daphnia magna): ≥ 10 mg/L (nominal, loading rate)(OECD 211).

Algae:

NOELR (72 h)( Desmodesmus subspicatus): 32 mg/L (nominal, loading rate, above the water solubility of the substance (WS < 0.05 mg/L)(OECD 201).

 

Non-classification justification according to CLP

Based on the data above, Glycerides, C14-18 and C16-18 unsaturated, mono-, di- and tri- (CAS No. 91052-28-7) is considered to be rapidly degradable and have low potential for bioaccumulation. The acute L(E)C50 values reported for fish, aquatic invertebrates and algae are > 1 mg/L.Therefore,Glycerides, C14-18 and C16-18 unsaturated, mono-, di- and tri-does not need to be classified and labelled as acute aquatic hazard according to the 2nd ATP of Regulation (EC) No.1272/2008 (CLP).

 

Valid chronic toxicity data are available, with NOEC values (for aquatic invertebrates and algae) > 1 mg/L.Thus, Glycerides, C14-18 and C16-18 unsaturated, mono-, di- and tri-does not need to be classified and labelled as long-term aquatic hazard according to the 2nd ATP of Regulation (EC) No.1272/2008 (CLP).

 

Non-classification justification according to DSD

Based on the data above, Glycerides, C14-18 and C16-18 unsaturated, mono-, di- and tri- (CAS No. 91052-28-7) is considered to be rapidly degradable and have low potential for bioaccumulation. The acute L(E)C50 values reported for fish, aquatic invertebrates and algae are > 1 mg/L. Glycerides, C14-18 and C16-18 unsaturated, mono-, di- and tri- does not need to be classified and labeled as environmental hazard according to Directive 67/548/EEC.
