- Mortality:
- No mortality occurred.

- Gross pathology:
- 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.
- Other findings:
- Treatment-related microscopic skin findings were as follows:
- Ulceration (characterized by full thickness loss of the epithelium through the basement membrane) was present in 5/6 2000 mg/kg treated rats at slight (3/6) or marked (2/6) degree.
- 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.
Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information for dermal acute toxicity Criteria used for interpretation of results: EU
- 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.
