Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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. In Annex XI, entitled "General rules for adaptation of this standard testing regime set out in Annexes VII to X” it is stated 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 available data on environmental fate and aquatic toxicity of the target substance hexadecyl palmitate (CAS 540-10-3) is limited, a read-across approach was applied and data was compiled from representative source substances to avoid unnecessary animal testing. The target substance will be classified and labelled on this basis.

Environmental fate and pathways

Degradation

Readily biodegradable: 75.3% BOD after 28 d (OECD 301 C); read-across

Bioaccumulation

Expert statement: Bioaccumulation is assumed to be low.

 

Aquatic short-term toxicity

96 h, LL50 (Danio rerio): > 100 mg/L (nominal, no toxic effects observed up to the limit of water solubility); read-across

48 h, EL50 (Daphnia magna): > 100 mg/L (nominal, no toxic effects observed up to the limit of water solubility); read-across

72 h, ErL50 (Pseudokirchneriella subcapitata/Desmodesmus subspicatus): > 100 mg/L(nominal, no toxic effects observed up to the limit of water solubility); read-across

 

Aquatic long-term toxicity

21 d, NOELR (Daphnia magna): ≥ 100 mg/L(nominal, no toxic effects observed up to the limit of water solubility); read-across

72 h, NOELR (Pseudokirchneriella subcapitata/Desmodesmus subspicatus): ≥ 100 mg/L(nominal, no toxic effects observed up to the limit of water solubility); read-across

 

Conclusion on CLP

Data for acute aquatic toxicity is available for all three trophic levels. Data for chronic aquatic toxicity is available for aquatic invertebrates and algae. The substance is considered rapidly degradable and neither short-term nor long-term toxic effects towards aquatic organisms were observed up to the limit of the water solubility of the substance. Therefore, the substance is not classified and labelled for environmental hazards according to the consolidated version of Regulation (EC) No 1272/2008 (dated: 01.01.2017) and further amendments (ATPs).
