Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Degradation

Biodegradation: readily biodegradable: 67% of tetradecyl myristate (OECD 301C)

Bioaccumulation

Expert statement: Bioaccumulation is assumed to be low.  

Aquatic acute toxicity

96 h, LC50 (Danio rerio): > 100 mg/L (nominal) and > 0.189 µg/L (measured) (No observed toxicological effects up to the water solubility limit)

72 h, ErL50 (Pseudokirchnerella subcapitata): > 100 mg/L (nominal) and > 1.465 µg/L (measured) (No observed toxicological effects up to the water solubility limit)

48 h, EL50 (Daphnia magna): > 100 mg/L (nominal) and > 0.128 µg/L (measured) (No observed toxicological effects up to the water solubility limit)

Aquatic chronic toxicity

72 h, NOELR (Pseudokirchnerella subcapitata): ≥ 100 mg/L (nominal) and ≥ 1.465 µg/L (measured) (No observed toxicological effects up to the water solubility limit)

CLP

Based on the data above, tetradecyl myristate is considered to be rapidly degradable. No acute aquatic toxicity was observed up to the water solubility limit (< 0.02 mg/L) for fish, algae and daphnids. Valid chronic data are available with a NOELR (72 h) ≥ 1.465 µg/L (i.e. above the limit of water solubility) for Pseudokirchnerella subcapitata. Therefore, tetradecyl myristate does not need to be classified and labelled as environmental hazard according to the 2nd ATP of the Regulation (EC) No.1272/2008 (CLP).

DSD

The substance is poorly soluble in water and no effects occurred up to its solubility limit in acute tests for fish, algae and aquatic invertebrates. Therefore, tetradecyl myristate does not need to be classified and labelled as environmental hazardous according to Directive 67/548/EEC.
