Test animals
- Species:
- rat
- Strain:
- other: Wistar strain, Crl:WI (Han)
- Sex:
- male/female
- Details on test animals or test system and environmental conditions:
- - Source: Charles River Deutschland, Sulzfeld, Germany.
- Age at study initiation: Young adult animals (approx. 11 weeks old)
- Weight at study initiation: Body weight variation was within +/- 20% of the sex mean.
- Housing: Individually housed in labeled Macrolon cages (MIII type, height 18 cm.) containing sterilized sawdust as bedding material (Woody-Clean type 3/4, Tecnilab-BMI BV, Someren, The Netherlands) and paper as cage-enrichment (Enviro-dri, Tecnilab-BMI BV, Someren, The Netherlands).
- Diet (e.g. ad libitum): Free access to pelleted rodent diet (SM R/M-Z from SSNIFF® Spezialdiäten GmbH, Soest, Germany).
- Water (e.g. ad libitum): Free access to tap water.
- Acclimation period: The acclimatization period was at least 5 days before the start of treatment under laboratory conditions.
- Health inspection: A health inspection was performed prior to treatment, to ensure that the animals were in a good state of health. Special attention was paid to the skin to be treated, which was intact and free from any abnormality.
Results of analysis for diet (nutrients and contaminants), sawdust, paper and water were assessed and did not reveal any findings that were considered to have affected the study integrity. All certificates and results of analysis are retained in the NOTOX archives.
ENVIRONMENTAL CONDITIONS

- 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).

- 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.

- Other examinations performed: none. - Statistics:
- None.
Results and discussion
Effect levels
- 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:
- other: 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.

Applicant's summary and conclusion
- 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.
