Test animals
- Species:
- rat
- Strain:
- other: Wistar strain, Crl:WI (Han)
- Sex:
- male/female
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Source: Charles River Deutschland, Sulzfeld, Germany.
- Age at study initiation: Young adult animals (approx. 12 weeks old) were selected
- Weight at study initiation: Body weight variation did not exceed +/- 20% of the sex mean.
- Fasting period before study: No
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
- Temperature (°C): : 20.0 - 22.0ºC
- Humidity (%): 38 - 56%
Temporary deviations from the minimum level of relative humidity occurred. Laboratory historical data do not indicate an effect of the deviations.

Administration / exposure
- Type of coverage:
- occlusive
- Vehicle:
- corn oil
- Remarks:
- specific gravity 0.92
- 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 formulation 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 formulation 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 (10 mL/kg) body weight
- No. of animals per sex per dose:
- 5
- Control animals:
- not required
- Details on study design:
- VEHICLE
- Justification for choice of vehicle: The vehicle was selected based on trial formulations performed at NOTOX and on test substance data supplied by the sponsor.
Dose level (volume): 2000 mg/kg (10 mL/kg) body weight.
DOSAGE PREPARATION: The formulation (w/w) was prepared within 4 hours prior to dosing. Homogeneity was accomplished to a visually acceptable level. Adjustment was made for specific gravity of the vehicle and the test substance.
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
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:
- Lethargy, hunched posture and/or piloerection were noted in two males and one female on Day 2. Chromodacryorrhoea was observed in one male on Days 1 and 2.
- Body weight:
- The mean body weight gain shown by the animals over the study period was considered to be similar to that expected of normal untreated animals of the same age and strain.
The incidence of slight body weight loss of animal no. 5 between Days 1 and 8 was considered not indicative of toxicity, based on the absence of any corroborative findings in this animal and since other animals showed normal weight gain. - Gross pathology:
- No abnormalities were found at macroscopic post mortem examination of the animals
Applicant's summary and conclusion
- Interpretation of results:
- study cannot be used for classification
- Remarks:
- Migrated information
- Conclusions:
- The dermal LD50 value of Standolized linseed oil in Wistar rats was established to exceed 2000 mg/kg body weight.
Based on these results, Standolized linseed oil 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.
