Additional information
No studies are available on the short-term toxicity of Fatty acids, tallow, zinc salts to aquatic invertebrates. In accordance to Regulation (EC) No 1907/2006 Annex XI, 1.5, a read across to the structural analogue Fatty acids, C16-18, zinc salts (CAS No. 91051-01-3) was conducted. Based on similar structure, physico-chemical properties and zinc content, the ecotoxicological profile of the two substances is expected to be comparable. Further justification is given within the endpoint summary 6.1 and the read-across justification. The data available for Fatty acids, C16-18, zinc salts and the supporting data available for inorganic zinc substances are discussed below.
Fatty acids, C16 -18, zinc salts:
The study conducted with Fatty acids, C16 - 18, zinc salts was performed according to the OECD Guideline 202, using Daphnia magna as test organism. The highest test concentration was prepared with a 100 mg/L loading to obtain a saturated solution in the range of water solubility. Additionally, four dilutions (factor 3.2) were prepared and tested. The test was performed at pH 6 and 8. No effects were observed at the tested concentrations. The toxicity of the substance fatty acids, C16 -18, zinc salts to Daphnia magna is thus (far) above the water solubility limit.
ZINC:
Many good quality and relevant data for 5 standard species are available. Tests were done according to standard protocol or equivalent.
Data are grouped per species according to
-pH: low (6 - <7) - neutral/high (7 -8.5)
-and hardness: low/medium (< 100 mg CaCO3/L) and medium/high (> 100 mg CaCO3/L).
Ceriodaphnia dubia is for all test conditions the most sensitive species.
For a comprehensive overview of the acute toxicity of (soluble) zinc to aquatic invertebrates,see Chemical Safety Assessment of "Zinc" within the framework of Regulation (EC) No 1907/2006 in the technical dossier (IUCLID section 13).
CONCLUSION:
Based on the study conducted with the structural analogue Fatty acids, C16 -18, zinc salts, the substance Fatty acids, tallow, zinc salts is not expected to have short-term effects on aquatic invertebrates up to its limit of water solubility.
