Acute Toxicity: oral
Administrative data
- Endpoint:
- acute toxicity: oral
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Original study is classified as reliable without restriction (Klimisch 1) because it was conducted according to GLP and followed guidelines (OECD 401, U.S. EPA/TSCA) that were acceptable at the time the study was performed. It is rated K2 (with restrictions) as it is on a surrogate substance.

Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- approximate LD50
- Effect level:
- > 10 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- 10 g/kg dose - 2/5 males and 2/5 females died
No lethality was observed at 5 mg/kg bw in either sex. - Clinical signs:
- other: Several reported clinical signs were linked to excessive excretion of the compound including red extremities, unkempt appearance, discharge on perineal fur, greasy wet perineal fur and hindlimb regions, and alopecia and scabs on the perineal fur, hind lim
- Gross pathology:
- Necropsy revealed discoloration in lungs, intestines (with distention), liver (1 animal) and kidneys in rats that died or were sacrificed during the study period. Surviving animals had no remarkable gross lesions. No lesions were found in tissues taken to evaluate neurotoxicity (brains, spinal cords, sciatic nerves and pituitaries
Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- No histopathological signs of lesions were found in the central or peripheral nervous system. Clinical signs were not considered to be related to the irritation of the abdominal and hindlimb areas. Based on these results, Gulftene 16 did not appear to produce primary neurotoxicant effect.
- Executive summary:
In an acute oral toxicity study, two groups of 10 (male and female) Sprague-Dawley albino rats, 7 to 13 weeks of age, which had fasted for 18 hours, were given a single oral dose of hexadec-1 -ene at 10 g/kg or 5 g/kg. These animals were observed for a total of 14 days. There was no treatment related clinical signs, necropsy findings or changes in body weight. The oral LD50 was determined to be >10 g/kg bw in both males and females. This result can be considered representative of the likely acute oral toxicity of the isomer 7 -methylenepentadecane.
