Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 SCAE Me 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:   75% in 28 days (BODIS Test, ISO Draft).

 

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

Acute toxicity:

Fish:   

LC50 (96 h)(Danio rerio): 550 mg/L (nominal, above the water solubility value of the substance, 0.004 mg/L)(ISO-7346-1).

Aquatic invertebrates:

EC50 (48 h)(Daphnia magna): > 0.02 mg/L (measured initial concentration)(read-across)(OECD 202).

Algae:

EC50 (72 h)(Pseudokirchneriella subcapitata): > 0.023 mg/L (measured TWA concentration)(read-across)(OECD 201).

 

Chronic toxicity:

Aquatic invertebrates:

NOEC (21 d)(Daphnia magna): ≥ 0.22 mg/L (measured TWA concentration)(read-across)(OECD 211).

Algae:

NOEC (72 h)(Pseudokirchneriella subcapitata): ≥ 0.023 mg/L (measured TWA concentration)(read-across)(OECD 201).

 

Non-classification justification according to CLP and DSD

Based on the data above, methyl palmitate (CAS No. 112-39-0) is considered to be rapidly degradable and have low potential for bioaccumulation. The acute and chronic aquatic toxicity data available showed no toxic effects on fish, daphnids and algae up to the limit of the water solubility of the substance (0.004 mg/L), and therefore effect concentrations (L(E)C50 and NOEC values) could not be determined. Considering this information, methyl palmitate does not need to be classified and labeled as environmental hazard according to the 2nd ATP of Regulation (EC) No. 1272/2008 (CLP) and Directive 67/548/EEC.
