other: see 'Remark'
Remarks:
Study performed according to an international guideline and according to GLP. The validity criteria were fulfilled except the lack of data relating to the analytical monitoring showing that the concentrations of the test item were maintained during the test. However, the test has been performed under semi-static conditions and according to the long-term toxicity to Daphnia, the substance is stable during 48 hours. Thus, we can considered that in a short-tem study, the susbtance is also stable.

No mortality were observed in the control up the end of the test. No mortality was observed up to 3.12 mg/l and 100% mortality was observed at 12.5 mg/L at the end of the test.
Executive summary:

The acute toxicity of the test item (= substance EC 939-455-3 in aqueous commercial product) to the freshwater fish Brachydanio rerio was investigated in a GLP-compliant study performed in accordance with OECD Guideline 203 (Fish, Acute Toxicity Test).

PREPARATION AND APPLICATION OF TEST SOLUTION
- Method : the test solutions were prepared without using of any organic solvent
- Stock solution :1 g of the test substance was added to drinking water (end-volume 1000 mL). Tis solution was then stirred for 30 minutes on the magnetic stirrer and the corresponding volumes from this were dosed using a pipette.

- Controls : no data
- Evidence of undissolved material (e.g; precipate, surface film, etc) : No
Test organisms (species):
Danio rerio (previous name: Brachydanio rerio)

In the control and at the test concentrations up to and including 2 mg/L, all fish survived until the end of the test

At the test concentration of 4 mg/L, all the fish died during the first 48 hours.Thus, the 96-hour NOEC of the test item to zebra fish was determined to be 2 mg/L. The 96-hour LC50 of the test item was calculated to be 2.8 mg/L. The 96-hour LC100 was determinated to be 4 mg/L.

Validity criteria fulfilled:

Executive summary:

The acute toxicity of the test item to the freshwater fish Brachydanio rerio was investigated in a GLP-compliant study performed in accordance with OECD Guideline 203 (Fish, Acute Toxicity Test).

Description of key information

The acute toxicity to the fish species Brachydanio rerio (freshwater sp.) and Scophthalmus maximus (seawater sp.) of the substance 1-Propanaminium, N-(3-aminopropyl)-2-hydroxy-N,N-dimethyl-3-sulfo-, N-(C8-18(even numbered) acyl) derivs., hydroxides, inner salts (EC 939-455-3) was investigated in two GLP-compliant studies (Mayordomo, 1996; Richardson, 2009) performed in accordance with standard methods. The results led to the following conclusions:

- Brachydanio rerio (freshwater): the substance exhibited a 96-hour LC50 of 2.66 mg active content/L based on nominal concentrations (as a 96-hour LC50 expressed in solid content was not reported, the 96-hour LC50 expressed in active content was used as a worst-case for the assessment);

- Scophthalmus maximus (seawater): the test item exhibited a 96-hour LC50 of >0.27 mg solid content/L based on nominal concentrations (limit test).

The acute toxicity to fish was otherwise investigated in two other studies (Schultz, 1995; Hill, 2006) which were not considered in the assessment due to major methodological deficiencies and insufficient documentation.

Key value for chemical safety assessment

LC50 for freshwater fish:
2.66 mg/L

Additional information

The acute toxicity to freshwater and marine fish species of the substance 1-Propanaminium, N-(3-aminopropyl)-2-hydroxy-N,N-dimethyl-3-sulfo-, N-(C8-18(even numbered) acyl) derivs., hydroxides, inner salts (EC 939-455-3) was investigated in two GLP-compliant studies (Mayordomo, 1996; Richardson, 2009) performed in accordance with standard methods, without deviations. Both studies are considered as reliable with restrictions (Klimisch 2) and were selected as key studies for the endpoint. The two other available studies (Schultz, 1995; Hill, 2006) are considered as not reliable (Klimisch 3) and were disregarded for the endpoint.
