Description of key information
Additional information
There are no data available investigating the aquatic toxicity of Lauric acid ester with hydroxypropanediyl diacetate (CAS 30899-62-8). In order to fulfil the standard information requirements, in accordance with Annex XI, 1.5, of Regulation (EC) No 1907/2006, read-across from a structurally related substance was conducted.
In accordance with Article 13 (1) of Regulation (EC) No 1907/2006, "information on intrinsic properties of substances may be generated by means other than tests, provided that the conditions set out in Annex XI are met.” In particular for aquatic toxicity, information shall be generated whenever possible by means other than vertebrate animal tests, which includes the use of information from structurally related substances (grouping or read-across). Having regard to the general rules for grouping of substances and read-across approach laid down in Annex XI, Item 1.5, of Regulation (EC) No 1907/2006 whereby substances may be predicted as similar provided that their physicochemical, toxicological and ecotoxicological properties are likely to be similar or follow a regular pattern as a result of structural similarity.
The target substance is a UVCB substance. It is characterized as a triester of glycerol esterified with acetic acid and lauric acid. A structurally very similar substance was selected as source substance to cover the data requirements. The source substance Glycerides, C8-21 and C8-21-unsatd. mono- and di-, acetates (CAS 97593-30-1) is a multi-constituent substance described as a triester of glycerol with acetic acid and lauric acid in a slightly different composition compared to the target substance. Thus, both substances are considered to be structurally similar and the information on the source substance can be used to predict the aquatic toxicity of the target substance. A detailed analogue approach justification is provided in the technical dossier (see IUCLID Section 13).
All available experimental data on the source substance were performed according to internationally accepted guidelines and indicate no evidence of acute and chronic toxicity to aquatic organisms. Data for all three trophic levels are available. No toxicity was observed up to the limit of water solubility in all available experimental studies. The water solubility of the target substance was determined to be <0.15 mg/L at 20 °C and pH=6.2 - 6.6. The short-term toxicity to fish was determined in a standard OECD guideline study from a suitable read-across substance. No mortality was observed after 96 h resulting in a LL50 > 100 mg/L (i.e. above the water solubility limit). The same was recorded for the toxicity to aquatic algae. No inhibition of growth of aquatic algae was observed in an experimental study according to OECD 201 up to the limit of water solubility. Due to the low water solubility, long-term testing to aquatic invertebrates was considered to be necessary to assess the aquatic toxicity. The available study performed with the suitable source substance resulted in a NOELR (21 d) ≥ 10 mg/L indicating no effects on reproduction up to the limit of water solubility. Long-term toxicity testing to fish was not considered to be necessary since there was no evidence from the available data that fish are more sensitive compared to aquatic invertebrates. No toxicity to fish was observed in the available acute tests. Thus, in order to avoid unnecessary vertebrate testing, no long-term testing with fish was proposed. The degradation process in commercial sewage treatment plants is not suspected to be inhibited by the target substance. One available study performed with activated sludge from a sewage treatment plant did not indicate a risk since respiration of activated sludge microorganisms was not inhibited.
Based on the results from a structurally similar read-across substance (in accordance to Regulation (EC) No 1907/2006 Annex XI, 1.5) it can be concluded that Lauric acid ester with hydroxypropanediyl diacetate exhibits no toxic effects on freshwater organisms up to the limit of the water solubility. As it can be seen in the data matrix of the analogue justification in IUCLID Section 13, all reliable data from the target and the source substances support the read-across by showing a consistent pattern of results.
