One male was found dead early in the morning of Day 8. This case of death was considered to be a result of an application injury. This male rat showed a marked respiratory distress and a marked loss of weight. The histopathological examination of the lung of this animal revealed aspiration pneumonia. - Clinical signs:
- other: The main symptom was respiratory distress seen in 3 males and 1 female. This symptom developed in consequence of aspiration of a little test suspension. The other findings were of no toxicological significance.
- Gross pathology:
- In the urinary bladder of male rat 2694, gritty contents were observed. This finding was of a spontaneous nature. No other macroscopic organ changes were seen.
- Other findings:
- Histopathology: Bronchopneumonia caused the respiratory distress and itself was caused by aspiration of test suspension (by the male rat that died at Day 8).
- Interpretation of results:
- other: not classified based on EU CLP Criteria
- Conclusions:
- Based on the results of the read across study, LD50 for the test substance, is considered to be >4250 mg/kg bw.
- Executive summary:
A study was conducted to determine the acute oral toxicity of the read across substance, mono- and di- C16 PSE, K+ (purity: ca. 85%), according to the OECD Guideline 401, standard acute method, in compliance with GLP. Five male and 5 female Fü-albino SPF rats were randomly selected for an acute oral toxicity study. Fasted rats were given a single dose of the test substance suspended in SSV (Standard Suspended Vehicle) by gavage at a dose level of 5000 mg/kg bw. They were observed for 15 d for toxic signs, mortality and body weight changes. All rats were examined for gross lesions. No compound-related deaths occurred. No compound-related incompatibility reactions were observed. No compound-related effect on body weight development appeared. No compound-related gross or microscopic lesions were observed. The LD50 was determined at >5000 mg/kg bw (i.e., equivalent to >4250 mg a.i./kg bw) (XXXX, 1987). Based on the results of the read across study, similar absence of toxicity and oral LD50 value can be expected for the test substance, 'mono- and di- C16 PSE, K+ and H3PO4'.

- No. of animals per dose:

- Details on study design:
- The test substance concentrations selected for the main study were based on the results of a pre-screen test. In the main study, four experimental groups of five female CBA/J mice were treated with test substance concentrations of 2.5, 5, 10 or 25% w/w for three consecutive days, by topical application on the ears. Five vehicle control animals were similarly treated, but with the vehicle alone (Liquid petrolatum). A positive control group with a-hexylcinnamaldehyde (HCA - 50%) was also included in the experiment. Five days after the last exposure, all animals were injected with 5-bromo-2'-deoxy-uridine (BrdU) and the draining (auricular) lymph nodes were then isolated and pooled for each animal. Cells were fixed using 70% ethanol and used for the measurement of the cell number and the BrdU determination (percentage of proliferating cells in "S" phase). Flow cytometry was conducted for analysis and stimulation index (SI) was recorded

- Under the study conditions, the test substance was considered to be non-sensitiser to the skin.
- Executive summary:
A study was conducted to determine the skin sensitisation potential of the test substance, 'mono- and di- C16 PSE, K+ and H3PO4' (assumed purity:98.5%) according to OECD Guideline 429 and US EPA OPPTS 870.2600 (LLNA), in compliance with GLP. The test substance concentrations selected for the main study were based on the results of a pre-screen test. In the main study, four experimental groups of five female CBA/J mice were treated with test substance concentrations of 2.5, 5, 10 or 25% w/w for three consecutive days, by topical application on the ears.

Cells were fixed using 70% ethanol and used for the measurement of the cell number and the BrdU determination (percentage of proliferating cells in "S" phase). Flow cytometry was conducted for analysis and stimulation index (SI) was recorded. Mortality/viability, body weights, clinical signs, ear size and irritation (and other local effects) were recorded as well. SI values were similar among the control and test groups and were below 3. Three concentrations (i.e.2.5, 5 and 25%) induced ear swelling. No mortality occurred and no clinical signs of systemic toxicity were observed in the animals of the main study. Body weights and body weight gain of experimental animals remained in the same range as controls over the study period. Under the study conditions, the test substance was considered to be non-sensitiser to the skin (MBRL, 2005).
