Local effects males:
In all animals of the male group well-defined erythema (grade 2) was observed on study day 1 and persisted in four of these animals until study day 2, while in one animal severe erythema (grade 4) was noticed on the same day. On study day 3, one male showed moderate erythema (grade 3), while in the other animals severe erythema (grade 4) was noted. Severe erythema (grade 4) was noted persisted in three animals until study day 8, and in one male each until day 10 or day 13. Thereafter, moderate erythema (grade 3) was observed in two males from study day 9 until study day 10 or day 14. In another animal this grade was observed from study day 13 until study day 14, while in a further male animal grade 3 was observed only on study day 14. The fifth animal revealed well-defined erythema (grade 2) from study day 9 until study day 14.
Slight edema (grade 2) was noted in all male animals on study day 1 and persisted in four animals until study day 2. In one animal moderate edema (grade 3) was observed from study day 2 until day 3 and in the other four animals on study day 3. On study day 6, all animals showed severe edema (grade 4) which persisted in one animal up to study day 7. In this animal the finding decreased to moderate edema (grade 3) on day 8. In the other animals moderate edema (grade 3) was observed on study day 7 and persisted in one animal until day 8 and in two other animals until study day 10. Slight edema (grade 2) was seen in two male animals from study day 8 or 9 until study day 10 and in a third animal from day 9 until day 14. The two other animals revealed slight edema from study day 13 up to study day 14. In two animals edema decreased to very slight edema (grade 1) and was seen from study day 13 until study day 14. Dermal blisters were noted in 4 male animals on study day 1. From study day 2 until study day 14, incrustations were noted in all animals. In addition, scaling was seen in all males from study day 6 until study day 10 and persisted in one male until day 14.. Erythema and edema beyond the application area were noted in three animals from study day 6 until study day 10 or 13. Descriptions of any dermal finding were recorded in the table of results as raw data.
Local effects females:
In all animals of the female group well-defined erythema (grade 2) was noted from study day 1 until study day 2 and persisted in two of these animals up to study day 3, while in the other three females moderate erythema (grade 3) was noted on the same day. Thereafter, severe erythema (grade 4) was observed in all animals until study day 10 and persisted in four females up to study day 14, while in the fifth female moderate erythema (grade 3) was seen from study day 13 until study day 14. In all females slight edema (grade 2) was observed from study day 1 until study day 2 and persisted in four females up to study day 3, while in one animal moderate edema (grade 3) was observed on study day 3. On study day 6, severe edema (grade 4) was seen in all female animals and persisted in four of these females up to study day 7. In one female moderate edema (grade 3) was seen on study day 7, which decreased to slight edema (grade 2) from study day 8 until day 14. Moderate edema (grade 3) was noticed in four females on study day 8 and persisted in two of these females up to study day 10. Slight edema (grade 2) was noticed in two of these females on study day 9 and persisted in these animals up to study day 10 or 14.
In three females very slight edema (grade 1) was noted from study day 13 until study day 14. Dermal blisters with partly destroyed uppermost layer of the skin were noted in one female animal on study day 1. Eczema like skin lesion was seen in two females from study day 9 until day 14. From study day 2 or 3 until study day 14 incrustations were noted in all animals. In addition, scaling was seen from study day 6 until study day 14 in these animals. Erythema and edema beyond the application area were noted from study day 6 until study day 13 or 14 in three animals. In the two remaining animals findings beyond the application area were noted on study day 13 only. Descriptions of any dermal finding were recorded in the table of results as raw data.

Additional information
Acute oral toxicity
In an acute oral toxicity study (Bioassay, 2015) performed according to the Acute Toxic Class method (OECD 423 guideline and GLP), doses of 2000 and 300 mg/kg bw of the test item Triisooctylamine (undiluted or preparations in corn oil Ph.Eur.) were administered by gavage to three test groups of three fasted Wistar rats each (2000 mg/kg bw in 3 females, 300 mg/kg bw in 6 females). The following test substance-related clinical observations were recorded, clinical signs occurred within 6 days after administration:
2000 mg/kg (single test group):
Delayed mortality in one animal on day 6
Two animals were sacrificed in a moribund state on day 6
Impaired general state in all animals
Poor general state in two animals
Dyspnoea in two animals
Piloerection in all animals
Staggering in two animals
Chromodacryorrhea in all animals
Apathy in two animals
Exsiccosis in all animals
Reduced defecation in two animals
Body weight reduction in all animals
Urine smeared fur in one animal
Macroscopic pathological findings in the animal that was found dead: Due to the advanced putrefaction no macroscopic pathological findings could be determined. No macroscopic pathological findings were noted in the two animals that were sacrificed in a moribund state.
300 mg/kg (first test group):
No mortality occurred
No clinical signs were observed
300 mg/kg (second test group):
No mortality occurred
Impaired general state in all animals
Piloerection in all animals.
The mean body weight of the surviving animals increased within the normal range throughout the study period with one exception in the first 300 mg/kg bw test group. In one female animal the body weight increased within the normal range during the first week, but the female revealed a stagnation of body weight during the second week. This effect is observed at times in the rat strain used, because in the required age range the female animals have already reached the phase of slow growth. As the affected animal did not show any concurrent clinical symptoms or change in behavior, the observed stagnation of body weight is considered to be unspecific. There were no macroscopic pathological findings in the surviving animals sacrificed at the end of the observation period. The acute oral LD50 was calculated to be LD50, oral, rat > 300 < 2000 mg/kg bw.
Acute dermal toxicity
In an acute dermal toxicity study (Limit Test) according to OECD 402 guideline and GLP (Bioassay 2014), young adult Wistar rats (5 males and 5 females) were dermally exposed to a single dose of 2000 mg/kg bw of the undiluted test item Triisooctylamine 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, local effects occurred within 14 days after application:
Well-defined to severe erythema (grade 2 to 4)
Very slight to severe edema (grade 1 to 4)
Scaling
Incrustations
Eczema like skin lesion
Dermal blisters, partly with destroyed uppermost layer of the skin
Additionally, erythema and edema were noted beyond the application site.
In the male group three animals showed loss of body weight during the first week, while one animal showed stagnation of body weight during the first week, but body weights were in all animals in a normal range during the second week. In the female group all animals showed loss of body weight during the first week, but they gained weight in a normal range during the second week. This effect was probably caused by the severe local findings during the study period. No macroscopic pathologic abnormalities were noted in the animals examined at the end of the study (5 males and 5 females). Accordingly, the acute dermal median lethal dose (LD50) was determined to be LD50, dermal, rat > 2000 mg/kg bw.
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 (EC) No 1272/2008. The oral
LD50 was smaller than 2000 but greater than 300 mg/kg bw. As a result
the substance is considered to be classified for acute oral toxicity cat
4 (H302 "harmful if swallowed") under Regulation (EC) No 1272/2008, as
amended for the tenth time in Regulation (EU) No 2017/776.
Classification concerning acute dermal toxicity is not warranted.
