- Housing: animals were group housed (up to 3 animals of the same sex and same dosing group together) in polycarbonate cages containing sterilized wooden fibers as bedding material equipped with water bottles.
- Animal enrichment: animals were provided with paper, except when interrupted by study procedures/activities.
- Diet: Pelleted rodent diet (SM R/M-Z from SSNIFF® Spezialdiäten GmbH, Soest, Germany), ad libitum. The feed was analyzed by the supplier for nutritional components and environmental
contaminants.

- Details on oral exposure:
- VEHICLE
- Supplier: Sigma-Aldrich, Steinheim, Germany
- Justification for choice of vehicle: Trial preparations were performed to select the suitable vehicle and to establish a suitable formulation procedure. These trials were not performed as part of this study and these preparations were not used for dosing.
- Specific gravity: 0.92
MAXIMUM DOSE VOLUME APPLIED: 10 mL/kg body weight
CLASS METHOD
- Rationale for the selection of the starting dose: The dose levels were based on the OECD test guidelines and were selected from the series 5 (lowest dose level), 50, 300 and 2000 (highest dose level) mg/kg body weight. The starting dose level should be the one that is likely to produce mortality in at least some of the animals and was selected based on available toxicity data of the test item. - Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- Group 1: 3 females
Group 2: 3 females - Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days; Animals were observed twice daily for general health and mortality.
- Frequency of observations: Post-dose observations were performed at periodic intervals on the day of dosing (at least three times) and once daily thereafter.
- Frequency of weighing: Day 1 (pre-dose), 8 and 15. A fasted weight was recorded on the day of dosing.
- Necropsy of survivors performed: yes - Statistics:
- No statistical analysis was performed.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on the results of an acute oral study, performed according to OECD guideline 423 and in
accordance with GLP principles, the oral LD50 value of Amines, C16-18 (even numbered)-alkyl , salts with phosphoric acid, mono- and di-C16-18 (even numbered) alkyl esters in Wistar Han rats was determined to exceed 2000 mg/kg bodyweight. According to the OECD 423 test guideline, the LD50 cut-off value was considered to exceed 5000 mg/kg body weight. As a consequence, Amines, C16-18 (even numbered)-alkyl , salts with phosphoric acid, mono- and di-C16-18 (even numbered) alkyl esters does not have to be classified and has no obligatory labelling requirement for acute oral toxicity according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2017) (including all amendments) and Regulation (EC) No 1272/2008 on classification, labelling and packaging of items and mixtures (including all amendments). - Executive summary:
An acute oral study was performed according to OECD guideline 423 and in accordance with GLP principles, six female rats were exposed at test item concentration of 2000 mg/kg bodyweight and observed for 14 days. No mortality occurred. Hunched posture was noted for three animals on Day 1. No clinical signs were observed in the other animals. The body weight gain shown by the animals over the study period was considered to be similar to that expected for normal untreated animals of the same age and strain. No abnormalities were found at macroscopic post mortem examination of the animals. The oral LD50 value of Amines, C16-18 (even numbered)-alkyl , salts with phosphoric acid, mono- and di-C16-18 (even numbered) alkyl esters in Wistar Han rats was established to exceed 2000 mg/kg body weight. According to the OECD 423 test guideline, the LD50 cut-off value was considered to exceed 5000 mg/kg body weight. Based on these results, Amines, C16-18 (even numbered)-alkyl , salts with phosphoric acid, mono- and di-C16-18 (even numbered) alkyl esters does not have to be classified and has no obligatory labelling requirement for acute oral toxicity according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2017) (including all amendments) and Regulation (EC) No 1272/2008 on classification, labelling and packaging of items and mixtures (including all amendments).
