- Validity criteria fulfilled:
- yes
- Conclusions:
- In a 96-h acute toxicity study according to OECD TG 203, Leuciscus idus were exposed to Fatty acids, C16 and C18, esters with sucrose, glycerol and ethylene glycol at nominal concentrations of 0 (control) 2000, 3000 and 4000 mg/L under static conditions. The test substance was directly transferred into the dilution water. No analytical control was performed.
The 96-h LC50 is 3100 mg/L (arithmetical determination), the 96-h LC0 is 2000 mg/L, the 96-h LC100 is 4000 mg/L. The reliability was assessed 2 because no analytical control was performed. - Executive summary:
In a 96-h acute toxicity study, Leuciscus idus (Golden Orfe) were exposed to Fatty acids, C16 and C18, esters with sucrose, glycerol and ethylene glycol at nominal concentrations of 0 (control), 2000, 3000 and 4000 mg/L under static conditions. The 96-h LC50 was 3100 mg/L (arithmetical determination). The LC0 and LC100 values, based on mortality, were 2000 and 4000 mg/L, respectively.
This toxicity study is classified as reliable with restrictions as any analytical monitoring was performed.
The following validity criteria are fulfilled: the mortality in the controls did not exceed 10% and constant test conditions were maintained throughout the test.

- Details on test solutions:
- PREPARATION AND APPLICATION OF TEST SOLUTION
- Method: One water accommodated fraction (WAF) was prepared 24 ± 1 hour prior to the start of the exposure. The test item is sparingly soluble and a complex mixture (UVCB). The limit concentration was therefore prepared as loading. An appropriate amount of the test item was grounded, weighed and transferred into a flask with an appropriate amount of dilution water to obtain a concentration of 120 mg/L. The solution was stirred for 24 hours at approx. 1100 rpm at 30 °C. After stirring, undissolved particles were removed by membrane filtration (membrane filter 0.45 µm, RC, Macherey-Nagel). The filter was saturated in order to avoid adsorption during the filtration. The first 25 mL of the filtrate were discarded. The filtration was interrupted for 15 minutes to for allow adsorption and saturation of the filter material with dissolved test item. Thereafter, the filtration was continued. The next 25 mL were discarded. The following water soluble fraction (WSF) was used in the test. During filtration, the filter was always kept covered. The test solution was aerated for approx. 30 minutes before use. This preparation procedure was repeated prior to the start of every interval. The test vessels were saturated with test solutions of the control and limit loading for at least 24 hours before the start of the exposure. - Test organisms (species):
- Danio rerio (previous name: Brachydanio rerio)
- Details on test organisms:
- TEST ORGANISM
- Common name: zebra fish
- Source: All fish used for brood fish were gained at the test facility from a single brood stock (supplier: Umweltbundesamt, Schichauweg 58, 12307 Berlin, Germany)
- Method of breeding and maintenance of the brood fish: A breeding stock of unexposed, mature zebrafish with an age of 9 months was used for egg production. Fish were free of macroscopically discernable symptoms of infection and disease. Spawners were maintained in aquaria with a loading capacity of a minimum of 1 L water per fish: temperature: 25 °C; dissolved oxygen concentration > 60 % of air saturation value; pH-value: 6.5 – 8.5; photoperiod: 16 h light / 8 h dark cycle; Diffuse light (7 – 750 Lux on water surface); Food: Artemia salina nauplii, 48 hours old, ad libitum; Daphnia magna, juvenile and adult daphnids, ad libitum; dry food sera vipan SERA, ad libitum; no disease treatments were administered.
Adult zebrafish were kept in separate aquaria. About 15 minutes before the start of artificial dawning, spawn traps (rectangular dishes (26 cm x 14 cm x 6 cm), covered with a stainless steel mesh and provided with artificial plants) were introduced into the aquaria. After the end of dawning (approximately 0.5 h), the glass dishes were gently removed. About 150 eggs were taken, washed gently with dilution water and immediately distributed to the test concentrations and the control (40 eggs for the control, the reference item and for the test item loading).
- Fertilization check: Approximately 2 h post fertilization, eggs were checked for fertilization. Every embryo was checked under a stereo microscope (40-fold magnification) for its blastomer phase. Eggs with only a 2 cell blastomer were regarded as not fertilised. These eggs as well as coagulated eggs were discarded.

TEST MEDIUM / WATER PARAMETERS
- Source/preparation of dilution water: Maintenance water was used. The water was filtered on activated charcoal and aerated for at least 30 minutes.:
- Intervals of water quality measurement: The water quality (pH-value, oxygen saturation, temperature) was measured daily in a surrogate chamber per limit loading and control from the freshly prepared and corresponding 24 hours aged test solutions, respectively. Total water hardness was measured before the beginning and after the end of exposure from dechlorinated water. The water temperature was measured continuously (once per hour) with a data logger in a separate glass beaker.

- Both target and source substance are Sucrose ester with long-chain fatty acids. In addition, the source substance contains glycerol and ethylene glycol moieties. Since these substances, as the long-chain fatty acids, are not harmful to aquatic organisms, this structural difference is not considered to alter the ecotoxicity of the source substance in comparison to the target substance.
- Reason / purpose for cross-reference:
- read-across source

- 96 h
- Dose descriptor:
- LC50
- Effect conc.:
- 3 100 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mortality (fish)
- Conclusions:
- In a 96-h acute toxicity study according to OECD TG 203, Leuciscus idus were exposed to Fatty acids, C16 and C18, esters with sucrose, glycerol and ethylene glycol at nominal concentrations of 0 (control) 2000, 3000 and 4000 mg/L under static conditions. The test substance was directly transferred into the dilution water. No analytical control was performed.
The 96-h LC50 is 3100 mg/L (arithmetical determination), the 96-h LC0 is 2000 mg/L, the 96-h LC100 is 4000 mg/L. The reliability was assessed 2 because no analytical control was performed. - Executive summary:

The 96-h LC50 was 3100 mg/L (arithmetical determination). The LC0 and LC100 values, based on mortality, were 2000 and 4000 mg/L, respectively.
This toxicity study is classified as reliable with restrictions as any analytical monitoring was performed.
The following validity criteria are fulfilled: the mortality in the controls did not exceed 10% and constant test conditions were maintained throughout the test.

Description of key information
LL50 (96h) > 120 mg/L (nominal) for Danio rerio (OECD 236)
Key value for chemical safety assessment
Additional information
One study investigating the short-term toxicity of Reaction products resulting from esterification of sucrose with saturated C16-18 (even numbered) fatty acids to fish is available. The study was performed according to GLP and OECD guideline 236 using embryonic stages of zebrafish as test organisms (Herrmann 2018). A nominal test concentration of 120 mg/L was tested as loading rate in a limit test. No coagulation of embryos, absence of somite formation, non-detachment of the tail or lack of heart-beat were recorded throughout the exposure time in control and treatment. Thus, the 96h-LL50 is determined to be > 120 mg/L based on nominal concentrations.
The conclusion that the test substance is not harmful to fish is confirmed by an additional study performed with the structurally related source substance Fatty acids, C16 and C18, esters with sucrose, glycerol and ethylene glycol was conducted. Both substances are Sucrose ester with long-chain fatty acids. In addition, the source substance contains glycerol and ethylene glycol moieties. Since these substances, as the long-chain fatty acids, are not harmful to aquatic organisms, this structural difference is not considered to alter the ecotoxicity of the source substance in comparison to the target substance.
The study with the source substance was performed according to OECD guideline 203 using Leuciscus ideus as test organism (Evonik 1991). Nominal concentrations between 2000 and 4000 mg/L were tested. No analytical monitoring was performed. The 96h-LC50 was determined to be 3100 mg/L based on nominal concentrations.
