- Executive summary:
Method: Five healthy male and five healthy non-pregnant and nulliparous female albino rats were dosed orally with Duomeen TDO, Lot #1400407 at 5.0 g/kg of body weight.
The rats were observed 1, 2 and 4 hours post dose and twice daily for 14 days for mortality and toxicity. Body weights were recorded pretest, weekly, at death and at termination in the survivors. All animals were examined for gross pathology. Abnormal tissues were preserved in 10% buffered formalin for possible future microscopic examination.
Although there was compound related mortality, a multi-dose LD50 was not performed as per client request.
Results: Seven of ten animals survived the 5.0 g/kg oral dose.
Three females died between Day 7 and Day 12 with pre-death physical signs of diarrhea, lethargy, ptosis, piloerection, emaciation, soiling of body surfaces and brown staining of the nose/mouth and anogenital areas. Two animals which died were not necropsied since they had been cannibalized. The other death had abnormalities of the lungs and gastrointestinal tract, as well as brown staining of the anogenital area. Physical signs of chromorhinorrhea, diarrhea, piloerection, emaciation, ptosis, soiling of body surfaces, and brown staining of the nose/mouth and anogenital areas were noted in survivors and were more prevalent in females.
Body weight increases were normal in 5/7 survivors. One male and one female lost weight during the first week of the study.
Necropsy results were normal in survivors.
Conclusion: The LD 50 is greater than 5.0 g/kg in males, less than 5.0 g/kg in females and greater than 5.0 g/kg for combined sexes.

− A fibrinous exudate (a focally fibrillar eosinophilic mass of exudative proteinaceous material and cellular debris) was present on the skin surface of all rats at a minimal (1/6), slight (1/6) or moderate (4/6 degree). The most severe exudate was seen in ulcerated areas.
− Acanthosis, thickening/hyperplasia of the epidermis (increase in the number of epithelial cell layers which may extend into the dermis), was present in the non-ulcerated /less severely affected areas of all rats at a slight (5/6) or moderate (1/6) degree. This was likely a reactive response to the test item.
− All rats had lymphogranulocytic inflammation (characterized by a mixture of predominately lymphocytic and some granulocytic inflammatory cells) present in the dermis at minimal (3/6), slight (1/6) or moderate (2/6) degree. Inflammation extended focally into the underlying panniculus muscle which separates the dermis from the underlying subcutaneous tissue. - Interpretation of results:

- Conclusions:
- The dermal toxicity of oleyl diamine was tested according to current OECD/EC guidelines and under GLP principles. The LD50 was determined to be > 2000mg/kg.
Based on these results, Oleyl diamine, dioleate does not have to be classified and has no obligatory labelling requirement for acute dermal toxicity according to the:
- Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2007),
- Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures. - Executive summary:
Assessment of acute dermal toxicity with Oleyl diamine, dioleate in the rat.
The study was carried out based on the guidelines described in:
- OECD No.423 (2001) "Acute Oral Toxicity, Acute Toxic Class Method"
- Commission Regulation (EC) No 440/2008, B1tris: "Acute Oral Toxicity, Acute Toxic Class Method"
- EPA, OPPTS 870.1100 (2002), "Acute Oral Toxicity"
- JMAFF guidelines (2011) including the most recent partial revisions.
- OECD No.402 (1987) "Acute Dermal Toxicity"
- Commission Regulation (EC) No 440/2008, B3: "Acute Toxicity (Dermal)"
- EPA, OPPTS 870.1200 (1998), "Acute Dermal Toxicity"
Oleyl diamine, dioleate was administered to two subsequent groups of three female Wistar rats by a single dermal application at 2000 mg/kg body weight for 24 hours. Animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed after terminal sacrifice (Day 15). Histopathology was conducted on the treated skin area from all rats.
Results: Hunched posture, lethargy, chromodacryorrhoea, piloerection and/or ptosis were shown by all animals between Days 1 and 10. The treated skin-area of all animals showed general or focal erythema, scales, scabs, a thickened area and/or fissures during the observation period.
The changes noted in body weight gain in males and females were within the range expected for rats used in this type of study and were therefore considered not indicative of toxicity.
Three animals for which an external macroscopic examination was conducted showed scab formation on the dorso-lumbar region of the skin. No other abnormalities were found at macroscopic post mortem examination of the animals.
Treatment-related histopathological findings in the treated skin area consisted of ulceration (complete loss of the epidermis) in most rats with a superficial fibrinous exudate (this correlated with the scab formation seen macroscopically) in all rats. There was hyperplasia of the epidermis (acanthosis) in the non-ulcerated areas of all rats. Furthermore, dermal lymphogranulocytic inflammation was present in all rats.
The dermal LD50 value of Oleyl diamine, dioleate in Wistar rats was established to exceed 2000 mg/kg body weight.
From the histopathological results it is concluded that Oleyl diamine, dioleate is an irritant and has corrosive potential when applied with an occlusive dressing to the rat skin at 2000 mg/kg for 24 hours.
Based on these results, Oleyl diamine, dioleate does not have to be classified and has no obligatory labeling requirement for acute dermal toxicity according to the:
- Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2007),
- Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures.

Additional information
Acute oral toxicity:
The acute oral toxicity of Tallow-diamine dioleate was evaluated in a study performed in compliance to GLP. In this study, five male and five female rats were dosed orally with Tallow-diamine dioleate (pure, without vehicle) at 5.0 g/kg of body weight. The rats were observed 1, 2 and 4 hours post dose and twice daily for 14 days for mortality and toxicity. Body weights were recorded pretest, weekly, at death and at termination in the survivors. All animals were examined for gross pathology and abnormal tissues were preserved for possible future microscopic examination.
Seven of ten animals survived the 5.0 g/kg oral dose. Three females died between Day 7 and Day 12 with pre-death physical signs of diarrhea, lethargy, ptosis, piloerection, emaciation, soiling of body surfaces and brown staining of the nose/mouth and anogenital areas. Two animals which died were not necropsied since they had been cannibalized. The other death had abnormalities of the lungs and gastrointestinal tract, as well as brown staining of the anogenital area. Physical signs of chromorhinorrhea, diarrhea, piloerection, emaciation, ptosis, soiling of body surfaces, and brown staining of the nose/mouth and anogenital areas were noted in survivors and were more prevalent in females.
Body weight increases were normal in 5/7 survivors. One male and one female lost weight during the first week of the study. Necropsy results were normal in survivors.
Conclusion: The LD 50 is greater than 5.0 g/kg in males, less than 5.0 g/kg in females and greater than 5.0 g/kg for combined sexes.
Acute dermal toxicity:
Testing for acute dermal toxicity was done using Oleyl-diamine dioleate rather than Tallow-diamine dioleate. Cross-reading between the two substances is acceptable on the basis of similarities of structure with same functional groups, and properties leading to common biological activity, and possible common metabolic degradation. Contrary to oleyl do tallow-alkyl chains also contain some C16-chains next to the C18-alkyl chains. If anything, the higher level of unsaturation in oleyl-alkyl chains can be considered a worst case representation compared to tallow. Due to this very great similarity between these two substances, are results obtained from Oleyl-diamine dioleate fully applicable for the evaluation of Tallow-diamine dioleate as well.
The acute dermal toxicity of Oleyl-diamine dioleate was evaluated following a single dermal application at 2000 mg/kg body weight for 24 hours in two subsequent groups of three female Wistar rats. Animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed after terminal sacrifice (Day 15). Histopathology was conducted on the treated skin area from all rats.
All animals showed hunched posture, lethargy, chromodacryorrhoea, piloerection and/or ptosis between Days 1 and 10. The treated skin-area of all animals showed general or focal erythema, scales, scabs, a thickened area and/or fissures during the observation period.
Treatment-related histopathological findings in the treated skin area consisted of ulceration (complete loss of the epidermis) in most rats with superficial fibrinous exudates, correlating with the scab formation seen macroscopically, in all rats.
The dermal LD50 value of Oleyl-diamine dioleate in Wistar rats was established to exceed 2000 mg/kg body weight.
Acute inhalation toxicity:
No data available. Due to irritating properties respiratory irritation would be in principle possible. Due to the low vapour pressure (< 0.0015 Pa at 20°C based on C12/14-diamine rather than Tallow-diamine dioleate salt) inhalation of vapours leading to irritation of airways will not occur. The indicated use pattern also does not give rise to a high concern for specific exposures via inhalation of these oleyl-diamine dioleate salts.
Tallow-diamine dioleate is a solid at 20°C, and its melting point is 38 °C. No classification for aspiration hazard is therefore warranted.
Justification for selection of acute toxicity – oral endpoint
Only study available
Justification for selection of acute toxicity – inhalation endpoint
No inhalation studies are needed when vp < 0.1 Pa at 20°C
Justification for selection of acute toxicity – dermal endpoint
Only study available.
Justification for classification or non-classification
The evaluation of available data leads to the conclusion that for Tallow-diamine dioleate, both the acute oral and acute dermal LD50 are determined to be above 2000 mg/kg bw, Consequently, Tallow-diamine dioleate does not need to be classified for acute oral or dermal toxicity for EU-CLP.
For inhalation route no data is available. However, in view of low likelihood of exposures related to very low vapour pressure no further testing is needed.
Tallow-diamine dioleate is a solid at 20°C, and its melting point is 38 °C. No classification for aspiration hazard is therefore warranted.
