Endpoint summary
Administrative data
Description of key information
Key studies for oral and dermal acute toxicity were performed, demonstrating LD50 >2000 mg/kg bw after both routes. Inhalation toxicity testing was waived based upon the fact that acute inhalation exposure as such is very unlikely for sulphosuccinates due to their substance properties and the risk management measures that are already implemented.

During the follow-up period (2 weeks) changes in skin and fur, eyes and mucous membranes, and the respiratory, circulatory, autonomic and central ner¬vous system and somatomotor activity as well as behaviour pattern were observed at least once a day until all symptoms subsided, thereafter each working day. Attention was also paid to possible tremors, convulsions, salivation, diarrhoea, lethargy, sleep and coma..
Observations on deaths were made at least once daily to minimize loss of animals during the study. Individual body weights were recorded before administration of the test item and thereafter in weekly intervals up to the end of the study. Changes in weight were calculated and recorded.
- Necropsy of survivors performed: yes. At the end of the experiments, all animals were sacrificed, dissected and inspected macroscopically. All gross pathological changes were recorded. No histopathology was carried out as no macroscopical findings were noted at necropsy.

Also, according to the EC Regulation 1272/2008 and subsequent regulations, the test item is not classified for acute dermal toxicity. - Executive summary:
Test item containing 95.8% active ingredient was tested in a acute dermal toxicity study. A single dermal administration of 2000 mg act.ingr. /kg bw to 5 male and 5 female CD rats for 24 hours under an occlusive patch,revealed no signs of toxicity and no deaths. A very slight erythema (barely perceptible) on the application site was observed in 5 of 5 male and 5 of 5 female animals on test days 2, 3 and 4. All animals gained the expected body weight throughout the whole experimental period.

Additional information
Acute oral toxicity
In a key acute oral toxicity study with registered substance, the test item containing 40% active ingredient was tested in young Wistar rats by single gavage as a 20% solution in 1% Carboxymethylcellulose – 0.5% Cremophor as solvent and an application volume of 10 mL/kg bw (Potokar, 1989). Five rats were used per sex. The LD50 was >2000 mg act.ingr. /kg bw for male and female rats. There were no clinical obervations or changes in body weight or macroscopic pathology.
In conclusion, there is no hazard for acute oral toxicity.
Acute dermal toxicity
In a key acute dermal toxicity study with registered substance, the test item containing 95.8% active ingredient was tested in CD rats under occlusion for 24 hours with 2000 mg act.ingr./kg bw (Haferkorn, 2013). There were no signs of toxicity and no deaths. A very slight erythema (barely perceptible) on the application site was observed in 5 of 5 male and 5 of 5 female animals on test days 2, 3 and 4. All animals gained the expected body weight throughout the whole experimental period and did not elicit gross pathological findings. LD50 was > 2000 mg/kg bw.
In conclusion, there is no hazard for acute oral toxicity.
Acute inhalation toxicity
Inhalation is very unlikely due to large particle size, low vapour pressure and high hydrophilic properties of the substance. Based on these and other physicochemical properties, the inhalation route is not appropriate; the oral and dermal route of administration are therefore applied as first and second relevant routes (ECHA R7a Guidance p 342). Additional inhalation testing would therefore neither lead to a better risk assessment, nor improve the safety of applications. On the basis of the argumentation summarized above an acute inhalation toxicity study is waived.
Conclusion
- There is no hazard for acute oral and dermal toxicity, based on LD50values >2000 mg/kg bw.
- Inhalation toxicity testing was waived based upon the fact that acute inhalation exposure as such is very unlikely.

Justification for classification or non-classification
Based on these results and according to the EC Directive (No.93/21/EEC) and CLP (No. 1272/2008 of 16 December 2008), classification is not obligatory for oral and dermal acute toxicity.
