Endpoint summary
Administrative data
Description of key information
The acute dermal toxicity of the substance was determined by experiment to exceed 2000 mg/kg bw. There are no relevant acute oral toxicity studies available for the test substance. Four oral acute toxicity studies were conducted with closely related structural analogues; the oral LD50 value was determined to be > 2000 mg/kg body weight in three of these studies and > 5000 mg/kg bw in one of these studies.

- occlusive
- Vehicle:
- unchanged (no vehicle)
- Details on dermal exposure:
- One day before exposure (Day -1) an area of approximately 5x7 cm on the back of the animal was clipped.
The test substance was applied in an area of approx. 10% of the total body surface, i.e. approx. 25 cm² for males and 18 cm² for females. The test substance was held in contact with the skin with a dressing, consisting of a surgical gauze patch (Surgy 1D)*, successively covered with aluminum foil and Coban elastic bandage*. A piece of Micropore tape* was additionally used for fixation of the bandages in females only.
*. Manufacturers: Laboratoires Stella s.a., Liege, Belgium (surgical gauze) and 3M, St. Paul, Minnesota, U.S.A. (Coban & Micropore).
Frequency: Single dosage, on Day 1.
Washing: Following application, dressings were removed and the skin cleaned of residual test substance using tap water. - Duration of exposure:
- 24 hours.
- Doses:
- 2000 mg/kg (2.105 mL/kg) body weight.
Dose volume calculated as dose level (g/kg) / specific gravity - No. of animals per sex per dose:
- 5
- Control animals:
- no
- Details on study design:
- Dose level (volume): 2000 mg/kg (2.105 mL/kg) body weight.
Dose volume calculated as dose level (g/kg) / specific gravity.
DOSAGE PREPARATION: The test substance was dosed undiluted as delivered by the sponsor.
Duration of observation period following administration: 14 days
- Frequency of observations and weighing:
Mortality/Viability: Twice daily
Body weights: Days 1 (pre-administration), 8 and 15.
Clinical signs: At periodic intervals on the day of dosing (Day 1) and once daily thereafter, until Day 15. The symptoms were graded according to fixed scales and the time of onset, degree and duration were recorded.
- Necropsy of survivors performed: yes
- Other examinations performed: none. - Statistics:
- None.
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occurred.
- Clinical signs:
- Chromodacryorrhoea (snout) was noted for two males and two females on Day 1. One of these females also showed lethargy and ptosis on Day 1. No further clinical signs were observed.
- Body weight:
- 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.
- Gross pathology:
- No abnormalities were found at macroscopic post mortem examination of the animals.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The dermal LD50 value of Decanoic acid, mixed esters with heptanoic acid, octanoic acid and trimethylolpropane in Wistar rats was established to exceed 2000 mg/kg body weight.
Based on these results, Decanoic acid, mixed esters with heptanoic acid, octanoic acid and trimethylolpropane 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 Labeling of Chemicals (GHS) of the United Nations (2007),
- Regulation (EC) No 1272/2008 on classification, labeling and packaging of substances and mixtures.

Additional information
Four oral acute toxicity studies are available for read-across substances:
In the first study conducted with CAS 11138-60-6 in accordance with OECD Guideline 401, the oral LD50 value in ICO: OFA-SD (IOPS Caw) rats was found to be > 2000 mg/kg body weight.
In the second study conducted with CAS 78-16-0 in accordance with OECD Guideline 401, the oral LD50 value in Crl:CD (SD)BR rats was determined to be > 2000 mg/kg body weight.
In the third study conducted with CAS 91050-89-4 in accordance with OECD Guideline 401, the oral LD50 value in Crl:CD (SD)BR was determined to be > 2000 mg/kg body weight.
In the fourth study with CAS 78-16-0 in accordance with EU Method B.1, the oral LD50 value in Wistar rats was determined to be > 5000 mg/kg body weight.
In a study conducted in accordance with OECD Guideline 402, the dermal LD50 value of decanoic acid, mixed esters with heptanoic acid, octanoic acid and trimethylolpropane in Wistar rats was established to exceed 2000 mg/kg body weight.
Justification for selection of acute toxicity – oral endpoint
No one study could be selected as 4 studies are available with read-across substances (all Klimisch 2 providing LD50 values of > 2000 mg/kg bw and >5000 mg/kg bw.
Justification for selection of acute toxicity – inhalation endpoint
In accordance with column 2 of Annex VIII, the acute inhalation test (as required in section 8.5.2.) does not need to be performed because the substance is of sufficiently low vapour pressure to preclude exposure via inhalation at significant volumes. Dermal exposure is considered to be the appropriate route of exposure and has been assessed accordingly.
Justification for selection of acute toxicity – dermal endpoint
Only 1 study is available with the test substance.
Justification for classification or non-classification
Based on the above mentioned results, classification according to the CLP Regulation (EC)1272/2008 and the Dangerous Substance Directive 67/548/EC is not necessary.
A report justifying the read-across approach is included in IUCLID Chapter 13.
