Conclusion
The acute oral median lethal dose (LD50) of the test material, HOE S 3580-2, in the Sprague-Dawley strain rat was found to be greater than 2000 mg/kg bw.
Executive summary
A study was performed to determine the acute oral median lethal dose (LD50) of the test material, administered undiluted, in the Sprague-Dawley strain rat. The method used followed that described in the OECD Guidelines for Testing of Chemicals (1981) No. 401 "Acute Oral Toxicity" referenced as Method B.1 in Annex V of EEC Commission Directive 84/449/EEC. A group of ten fasted Sprague-Dawley Rats (five males and five females) was given a single oral dose of undiluted test material at a dose level of 2000 mg/kg bodyweight. There were no deaths. No evidence of systemic toxicity was noted during the study period. No toxicologically significant effects on bodyweight were noted during the study period. No abnormalities were noted at necropsy of animals killed at the end of the study. The acute oral median lethal dose (LD50) of the test material in the Sprague-Dawley strain rat, was found to be greater than 2000 mg/kg body-weight.

- Executive summary:
In an acute dermal toxicity study (Limit Test), young adult Wistar rats(5 males and 5 females)were dermally exposed to a single dose of 5000 mg/kg bw of the undiluted test item L-Glutamic acid, N-coco acylderivs., disodiumsalts to the clipped skin (dorsal and dorso-lateral parts of the trunk) and covered by semi-occlusive dressing for 24 hours. The application area comprised at least 10% of the total body surface area. The animals were observed for 14 days.
- No mortality occurred
- No signs of systemic toxicity were observed
- The following test item-related local effects were recorded during the course of the study:
o Very slight erythema (grade 1)
- The mean body weight of the male animals increased within the normal range throughout the study period.
- The mean body weight of the female animals did not adequately increase during the first post-exposure observation week, probably due to the bandage procedure, but increased during the second week within the normal range.
- No macroscopic pathologic abnormalities were noted in the animals examined at the end of the study.
Accordingly, the acute dermal median lethal dose (LD50) was determined to be LD50, dermal, rat > 5000 mg/kg bw.

Additional information
Oral:
To determine the acute oral median lethal dose (LD50), a study was performed with L-Glutamic acid, N-coco acyl derivs., monosodium salts (CAS 68187-32-6). A group of ten fasted animals (five males and five females) was given a single oral dose of undiluted test material at a dose level of 2000 mg/kg bodyweight. There were no deaths. No evidence of systemic toxicity was noted during the study period. No toxicologically significant effects on bodyweight were noted during the study period. No abnormalities were noted at necropsy of animals killed at the end of the study. The acute oral median lethal dose (LD50) of the test material in the Sprague-Dawley rat was found to be greater than 2000 mg/kg body-weight.
Dermal:
In an acute dermal toxicity study (limit test), young adult Wistar rats (5 males and 5 females) were dermally exposed to a single dose of 5000 mg/kg bw of the undiluted test item L-Glutamic acid, N-coco acyl derivs., disodium salts(CAS 68187-30-4)to the clipped skin (dorsal and dorso-lateral parts of the trunk) and covered by semi-occlusive dressing for 24 hours. The application area comprised at least 10% of the total body surface area. The animals were observed for 14 days. No mortality, clinical signs or macroscopic changes occurred. Accordingly, the acute dermal median lethal dose (LD50) was determined to be LD50, dermal, rat > 5000 mg/kg bw.
The read across justification is given in an extra rationale document.
Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. No mortality occurred at the limit doses. As a result, the substance is not considered to be classified for acute oral or dermal toxicity under Regulation (EC) No. 1272/2008, as amended for the fourteenth time in Regulation (EC) No. 2020/217.
