- Executive summary:
The acute toxicity of Betadet SH-R to Zebra fish (Brachydanio rerio) was determined in a static study carried out according to OECD test guideline 201 (1992). Fish were exposed to nominal test concentrations of 0 (control), 3.12, 6.25, 8.84 and 12.5mg/L for 96 hours. No analytical verification was performed therefore the results of the study are based in the nominal exposure concentrations.
The 96 h LC50 for Betadet SH-R, based on nominal exposure concentrations was calculated to be 6.4 mg/L (95% CI of 5.12 - 7.96 mg/L).
- Endpoint:
- short-term toxicity to fish
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- November 13, 1996 (final report)
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Study performed according to an international guideline but not 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. HHowever, 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.

- 10 fish per replicate. A total of 20 fish were exposed per concentration
- Validity criteria fulfilled:
- yes
- Remarks:
- See remarks "Rationale for reliability incl. deficienties"
- Conclusions:
- The toxicity test meets quality criteria provides in test Guidelines :
- not more than 10% of the control fish were dead
- the Dissolved Oxygen Cocentrations were greater than 60% of the air saturation value at the temperature tested at the end of the test
- test temperature did not vary more than 1°C in any 24-hour period - Executive summary:
The acute toxicity of the test item to Fathead Minnow (Pimephales promelas) was determined in a 96-hour static test according the OECD Guideline for Testing of Chemicals No. 203 (1992) but not according to the principles of Good Laboratory Practices. Fathead Minnow were exposed to control and test chemical at the nominal concentrations of 1.0, 2.5, 5.0, 7.5, and 10.0 mg/L. The test fish were observed after 24, 48, 72 and 96 hours test duration for mortality and visible abnormalities. At the test concentrations of 1.0 and 2.5 mg/L, 20% of mortality was observed at the end of the test (96 -hours exposure). At the test concentrations of 7.5 and 10 mg/L (20 fish exposed/concentration), the death of all the fish was recorded during the first 24h of test duration. Clinical signs were exposed during the study period as : erratic swimming and some hemorrhaging.
The 96-hour LC50 to Fathead Minnow was calculated to be 4.87 mg test item/L (2.12 mg active ingredient/L).

- 10 fish per replicate. A total of 20 fish were exposed per concentration
- Validity criteria fulfilled:
- yes
- Conclusions:
- The toxicity test meets quality criteria provides in test Guidelines :
- not more than 10% of the control fish were dead
- the Dissolved Oxygen Cocentrations were greater than 60% of the air saturation value at the temperature tested at the end of the test
- test temperature did not vary more than 1°C in any 24-hour period - Executive summary:
The acute toxicity of the target substance, C12 -14 cocamidopropyl hydroxysultaine (C12 -14 AAPHS), to fathead minnow (Pimephales promelas) was estimated based on read-across from a study testing C12-18 cocamidopropyl hydroxysultaine (C12-18 AAPHS). Given that C12 -14 AAPHS and C12-18 AAPHS share the same functional groups and general composition, the main variable being alkyl chain distribution, C12-18 AAPHS was considered appropriate for the purposes of read-across to C12 -14 AAPHS.
The acute toxicity of C12-18 AAPHS to Fathead Minnow (P. promelas) was determined in a 96-hour static test according the OECD Guideline for Testing of Chemicals No. 203 (1992) but not according to the principles of Good Laboratory Practices. Fathead Minnow were exposed to control and test chemical at the nominal concentrations of 1.0, 2.5, 5.0, 7.5, and 10.0 mg/L. The test fish were observed after 24, 48, 72 and 96 hours test duration for mortality and visible abnormalities. At the test concentrations of 1.0 and 2.5 mg/L, 20% of mortality was observed at the end of the test (96 -hours exposure). At the test concentrations of 7.5 and 10 mg/L (20 fish exposed/concentration), the death of all the fish was recorded during the first 24h of test duration. Clinical signs were exposed during the study period as erratic swimming and some haemorrhaging.
The 96-hour LC50 to Fathead Minnow was calculated to be 4.87 mg C12-18 AAPHS /L (equivalent to 2.12 mg active ingredient/L), and is considered appropriate for read-across purposes to C12 -14 AAPHS.
