MAXIMUM DOSE VOLUME APPLIED: 5 ml /kg
CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: Based on the physical and chemical characteristics of the test substance and its composition, no pronounced acute oral toxicity was expected. Therefore, a starting dose of 2000 mg/kg body weight (limit test) has been chosen in the first step with 3 female animals. As none of those animals died, 2000 mg/kg body weight were administered to 3 male animals in a second step. Because no mortality occurred either the study fulfilled the criteria for a limit test and was terminated. - Doses:

- Reliability:
- 2 (reliable with restrictions)

- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The test was performed in principle as described in OECD test guideline 403. It demonstrates the toxicity of an atmosphere saturated with vapors of the volatile components of a test substance at 20°C. Young adult laboratory rats, 6 per sex, were exposed sequentially to the vapors generated by bubbling 200 L/h air through a substance column of about 5 cm above a fritted glass disc in a glass cylinder for 8 h. The exposure was subsequently repeated in the same manner. No analytical determination of the atmosphere concentrations was performed. The nominal concentration was calculated as quotient of the amount of test substance weight loss during exposure, and the amount of air used during exposure. Group-wise documentation of clinical signs was performed over a 7 day study period. Body weight of groups was determined before the start of the study and at the end of the observation period.

Additional information
Oral:
Acute oral toxicity was evaluated in a reliable GLP-study conducted according to OECD 423. Three male and three female Wistar rats received doses of 2000 mg/kg bw of iso-tridecan-1 -ol in olive oil Ph.Eur./DAB (BASF, 2002). No mortality occurred during the observation period of at least 14 days. 5 hours after administration piloerection was observed in the male animals. No clinical signs were observed in the female animals. Under the conditions of this study the median lethal dose was found to be greater than 2000 mg/kg body weight for male and female rats.
In a reliable publication of Smyth, H.F. et al (1962) the single oral toxicity of the test substance was determined by gastric intubation of groups of 5 non-fastened, male Carworth Wistar rats. The LD50 was determined as 17.2 ml/kg bw (ca. 14500 mg/kg bw).
In a publication by Scala & Burtis (1973), the LD 50 for Tridecanol was estimated as 4750 mg/kg in male rats. Except for the LD50 value, no data on mortality was reported, but the authors state that the mortality pattern did not allow derivation of a reliable LD50 value. Even so, the data support the low oral toxicity observed in the remaining studies.
In an old study by BASF (1963), five mice per sex and group were treated from 169 mg/kg to 5395mg/kg. Symptoms on the day of exposure included reduced activity and intermittant respiration without clear dose dependency. There were no symptoms on the following days or during necropsy. One mouse in the high dose group died after 5 days without clinical symptoms. The LD50 was thus above 5395mg/kg.
Data on the three structurally similar alcohols also show low toxicity of this group of substances:
CAS 10042 -59 -8 (Propylheptanol): LD 50 = 5400 mg/kg (rat)
CAS 27458 -94 -2 (Isononanol): LD 50 = 3950 mg/kg (rat)
CAS 25339 -17 -7 (Isodecanol): LD50 = app. 4600mg/kg (mouse)
Inhalation:
Data of the acute inhalation toxicity of CAS 27458 -92 -0 are restricted to inhalation hazard tests.
6 male and 6 female Wistar rats were exposed (nose/head only) to a saturated test substance atmosphere of 0.3 mg/L (nominal) for 8 h (BASF, 1963). The observation period lasted 7 days. No mortality or clinical signs were observed. The test was performed in principle as described in OECD test guideline 403, but it was conducted before the implementation of GLP and OECD Guidelines. It should be noted that the concentration was determined by weighing of the test substance prior and after the exposure. The calculated saturated vapour concentration is 0.006mg/L, which means that (more likely) test substance adhered to the testing apparatus and was lost for the experiment, resulting in a lower exposure concentration, or that a mixture of vapour and aerosol was tested.
In an Inhalation Risk Test performed by Smyth, H.F. et al. (1962) concentrated vapor was inhaled by groups of 6 male or female albino rats. The temperature at vapor generation was room temperature. Vapor saturation at 20°C is 0.0064 mg/l (vapor pressure (20°C): 0.00078 hPa). Inhalations were continued for 8 hours. The observation period lasted 14 days. After the 8 hour-exposure no mortality occurred. No information on clinical signs was given.
In a third IRT by Scala & Burtis (1973), all rats, mice, and guinea pigs (10 per species) survived inhalation of the saturated vapour for 6 hours. Only slight signs of local irritation were noted. All animals appeared normal within 1h after exposure. No effects were noted during necropsy. Thus the LC50 is above the saturated vapour concentration for these three species, calculated as 0.0063mg/L, based on the moleculare weight of Tridecanol.
Data on the three structurally similar alcohols also show no mortality at saturated vapour concentration. Additionally, in a study equivalent to OECD 403, an LC50 value for Isononanol (CAS 27458 -94 -2) above 21.7 mg/L was determined for mice, rats, and guinea pigs.
Dermal:
Acute dermal toxicity was determined by a method closely akin to the one-day cuff method of Draize et al. (1944) using groups of 4 male albino rabbits (Smyth, H.F. et al, 1962). The fur was removed by clipping and the dose was retained beneath an impervious plastic film (i.e. occlusive). The animals were immobilized/exposed for 24 hours. Afterwards, the film was removed and the animals were observed for 14 days. An LD50 value of 7.07 ml/kg bw (ca. 5960 mg/kg bw) was established. No information on clinical signs was given.
In the publication of Scala, R.A. and Burtis, E.G. (1973) tridecanol was applied full-strength to the closely clipped, intact abdominal skin of albino rabbits in groups of four. The exposed area was covered with an occlusive binding of dental damming for 24 hours. After the exposure, the binding was removed, and the remaining material was cleaned from the skin. The observation period was 7 days and a LD50 of > 2600 mg/kg bw was established. No mortality and signs of toxicity were observed, but moderate irritation could be seen.
Data on the three structurally similar alcohols also show low toxicity of this group of substances:
CAS 10042 -59 -8 (Propylheptanol): LD 50 > 5010 mg/kg (rabbit)
CAS 27458 -94 -2 (Isononanol): LD 50 > 4000 mg/kg (rat)
CAS 25339 -17 -7 (Isodecanol): LD50 > 2600 mg/kg (rabbit)
Justification for classification or non-classification
Concerning acute toxicity, the available data is conclusive. No classification according to 1272/2008/EC (CLP) criteria is required.
