Details on oral exposure:
In the preliminary study, one female was dosed with 2000 mg/kg bw .In the main study, five males and five females were dosed with 2000 mg/kg bw. Animals were fasted 18 hour prior to treatment. The test substance was administered orally by gastric intubation using a metal catheter. The solutions were prepared immediately prior to dosing. A single dose was given at a volume of 10 mL/kg bw. The quantity was based on bodyweight at the time of dosing. Food was replaced three hours following dosing.

Details on study design:
The rats were observed at least twice daily for 7 days (preliminary study) or for 14 days (main study), after which they were sacrificed. Observations included changes in skin and fur, eyes and mucous membranes, respiratory, circulatory, central and autonomous systems, somatomotor activity and behaviour patterns.
Body weights were recorded before administration, daily for the first three days, then weekly and prior to being sacrificed. Rats were sacrificed by carbon dioxide inhalation. The animals in the main study were subjected to necropsy. The necropsy included a revision of the intact animal and its superficial tissues, followed by observation of the cranial, thoracic and abdominal cavities in situ and after evisceration.

Soft faeces were noted on the day following treatment. No other clinical signs were noted during the seven day observation period. A main experiment comprised five animals/sex. Soft faeces were noted on the day following treatment. There were no other clinical signs, mortality or post mortem observations. Body weight gain was normal.

Interpretation of results:
Category 5 based on GHS criteria
Conclusions:
The acute oral toxicity of the substance is therefore >2000 mg/kg bw based on the results of this study; classification for acute oral toxicity is not required based on the CLP criteria.
Executive summary:

C8 -18 cocamidopropyl hydroxysultaine (as a 42% aqueous solution) was tested for acute oral toxicity in Wistar rats according to OECD 401. The test material was administered without dilution and using different dosing volumes. Three groups of five rats/sex were dose with 1000, 2000 and 3000 mg kg bw (as the active component) and observed for 14 days. Deaths occurred at 3000 mg/kg bw (3M, 2F) and at 2000 mg/kg bw (2F). No deaths occurred at 1000 mg/kg bw. Clinical signs (including reduced activity, diarrhoea, squatting position, piloerection) were observed at 3000 mg/kg bw. Bodyweight gain was normal in surviving animals. Haemorrhagic and lytic mucous membrane alterations in the gastrointestinal tract were observed at necropsy of decedents at 2000 and 3000 mg/kg bw. No findings were noted at scheduled necropsy. The acute oral toxicity of the substance is therefore >2000 mg/kg bw based on the results of this study

Enlargement of the spleen was found in all treated animals but was considered incidental as it is part of the normal background in untreated rats of these strain and age.
Other findings:
Due to enlargement seen at necropsy, spleens were preserved in 10% buffered formalin and stored. In the absence of toxicological relevance, no histopathology was conducted and these organs were therefore destroyed upon finalization of the study report.

Interpretation of results:

Remarks:

Conclusions:
The dermal LD50 in rats was higher than 2000 mg active ingredient/kg bw.
Executive summary:

Cocamidopropyl hydroxysultaine, as a 36.2% solution (Mackam CBS-50GE), has been tested for acute dermal toxicity in Sprague-Dawley rats. The test article was applied as a single dose under a semi-occlusive dressing for 24 hours. One group of 5 rats per sex received a dose of 2000 mg active ingredient/kg bw. Examinations for mortality and clinical signs were performed daily during the 14 -day study period. Animals were necropsied at the end of the observation period.

 

No mortality was observed. No clinical signs indicative of systemic toxicity were observed. Very slight or well defined erythema was noted at the application site for 2 females on day 2. Mean bodyweight gain was slightly lower than historical control data for females over the observation period, notably during the first week following application. However, no such changes were observed for males. Enlargement of the spleen was found in all treated animals but was considered incidental as it is part of the normal background in untreated rats of these strain and age.

The dermal LD50 in rats was therefore higher than 2000 mg active ingredient/kg bw.

Additional information

Acute oral toxicity

An acute oral toxicity study with the submission substance Betadet SHR [Propanaminium, N-(3 -aminopropyl)-2 -hydroxy-N,N-dimethyl-3-sulfo-, N-(C12-14(even numbered) acyl) derivs., hydroxides, inner salts] was conducted using a fixed dose method (Tortajada, 1995). Wistar rats were dosed with 2000 mg/kg bw. A preliminary experiment comprising one female showed no mortality. Soft faeces were noted on the day following treatment. No other clinical signs were noted during the seven day observation period. A main experiment comprised five animals/sex. Soft faeces were noted on the day following treatment. There were no other clinical signs, mortality or post mortem observations. Body weight gain was normal. The overall conclusion of the study was that the test material showed no significant signs of toxicity.

Although not required for this endpoint, a supporting acute oral toxicity study with the read-across (analogue) substance [Propanaminium, N-(3 -aminopropyl)-2 -hydroxy-N,N-dimethyl-3-sulfo-, N-(C12-14(even numbered) acyl) derivs., hydroxides, inner salts]; this study also reports an acute oral LD50 of >2000 mg/kg bw.

Acute inhalation toxicity

A waiver is provided for acute inhalation toxicity based on exposure considerations.

Acute dermal toxicity

An acute dermal toxicity study with cocamidopropyl hydroxysultaine, as a 36.2% solution (Mackam CBS-50GE) was conduced in Sprague-Dawley rats. The test article was applied as a single dose under a semi-occlusive dressing for 24 hours. One group of 5 rats per sex received a dose of 2000 mg active ingredient/kg bw.  No mortality was observed. No clinical signs indicative of systemic toxicity were observed. Very slight or well defined erythema was noted at the application site for 2 females on day 2. Mean bodyweight gain was slightly lower than historical control data for females over the observation period, notably during the first week following application. However, no such changes were observed for males. Enlargement of the spleen was found in all treated animals but was considered incidental as it is part of the normal background in untreated rats of these strain and age. The dermal LD50 in rats was therefore higher than 2000 mg active ingredient/kg bw.

Justification for classification or non-classification

No classification for acute oral or dermal toxicity is required, based on the results of the available acute oral and acute dermal toxicity studies.
