Description of key information

No toxic effects up to the limit of water solubility (< 0.01 mg/L) for Daphnia magna (OECD 211). The key value refers to the maximum loading tested.

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
10 mg/L
EC10, LC10 or NOEC for marine water invertebrates:
10 mg/L

Additional information

Considering the very low solubility of tetradecyl laurate in water and its rapid degradation in the aquatic environment, long-term exposure in the aquatic environment is not considered to be of great concern. However, to evaluate the possible risk reference is made to the long-term toxicity to aquatic invertebrates of the structurally related category of fatty acids, C8-10, C12-18-alkyl esters (CAS 95912-86-0). A study was performed with fatty acids, C8 - 10, C12 - 18-alkyl esters (CAS 95912-86-0) according to OECD 211 (GLP; Salinas, 2013). Daphnia magna was exposed to a nominal loading rate of 10 mg/L (Water Accommodated Fraction). Chemical analysis of the test substance concentrations was not possible since no suitable analytical method could be developed to detect the test substance. No effects on reproduction of D. magna were observed up to the water solubility limit (< 0.05 mg/L) resulting in a no observed effect loading rate (NOELR) for 21 d of ≥ 10 mg/L. These results of a reproduction study with a structurally related substance (in accordance to Regulation (EC) No 1907/2006 Annex XI, 1.5) indicate that tetradecyl laurate will not exhibit chronic effects to aquatic invertebrates up to the limit of its water solubility.
