- Details on study design:
- A. INDUCTION: INTRADERMAL INJECTIONDay 1- treated group: An area of dorsal skin from the scapular region (approximately 6 x 8 cm) was clipped free of hair. Three pairs of intradermal injections (0.1 ml/site) were made at the border of a 4 x 6 cm area in the clipped region as follows: injection 1: a 1:1 mixture Freunds Complete Adjuvant (FCA)/physiological saline injection 2: 5 % of the test substance in bi-distilled water solution injection 3: 5 % of the test substance in water solution formulated in a 1:1 mixture FCA/waterDay 1- control group: Three paires of intradermal injections of 0,1 ml volume were applied to the shaved area. injection 1: a 1:1 mixture FCA/physiological saline injection 2: bi-distilled water for injection injection 3: 1:1 (w/w) mixture of bi-distilled water in a 1:1 (v/v) mixture of Freund's Complete Adjuvant and physiological saline. INDUCTION: TOPICAL APPLICATIONDay 8- treated group: Tested area was again shaved on day 7. On the identical site of intradermal injection was applied a filter paper (2x4cm) which was loaded with 50% of tested substance in white vaseline and held in contact by an occlusive dressing. The patch was covered with aluminum foil and firmly secured by an elastic plaster wrapped around the trunk of the animal and secured with impervious adhesive tape. The dressings were left in place for approximately 48 hours. The epidermal application procedure described ensured intensive contact of the test article. Day 8- control group: Tested area was again shaved. White vaseline was applied to an identical area of intradermal injection on filter paper (2x4 cm) in occlusive dressing for 48 hours. The gauze pad was kept in contact with the skin by an adhesive hypoalle rgenic patch under an occlusive aluminum foil sheet. B. CHALLENGE: TOPICAL APPLICATIONDay 22- treated and control group: On the right side of the animals was applied a filter paper (2x2 cm) impregnated with 25% solution of the tested substance in water for injections, occlusive dressing covered a period of 24hrs. After 24 and 48 after the patch removal, the challenge area was cleaned with water and was carried out clinical trials, focusing on the intensity of erythema and edema.

- Group:
- positive control
- Remarks on result:
- positive indication of skin sensitisation
- Interpretation of results:
- Category 1 (skin sensitising) based on GHS criteria
- Conclusions:
- The tested substance is a skin sensitizer.
- Executive summary:
In this study 40% of the animals were positive at the 24-hour reading and 25% at the 48-hour reading after treatment with a non-irritant test substance concentration of 25% in vaselinum album.
The response of at least 30% positive animals is considered positive and the substance needs to be classified as H317 following the Regulation (CE) 1272/2008.
Reference
Pathology - Necropsy: No necropsies were performed on the animals sacrificed at termination of the observation period.
The animals were sacrificed with an intraperitoneal injection of NARCOREN (Rhone Merieux GmbH, D-88471 Laupheim) at a dose of at least 5.1 ml/kg body weight (equivalent to 810 mg sodium pentobarbitone/kg body weight) and discarded.
Clinical signs: No symptoms of systemic toxicity were observed in the animals.
Body weight: The body weight of the animals was within the normal range of variability. Three animals of the test group and three of the
epidermal pretest lost weight during the acclimatization period. They had recovered during the treatment period.
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (sensitising)
- Additional information:
The response of at least 30% positive animals is considered positive "R43" following the "Commission Directive 93/21/EEC, April 27, 1993 adapting to technical progress for the 18th time Council Directive 67/548/EEC on the approximation of the laws, regulations and administrative provisions relating to the classification, packaging and labelling of dangerous substances".
Therefore the tested substance should be considered to be a sensitizer.
Justification for selection of skin sensitisation endpoint:
The study was performed on a tested substance with a higher content of active ingredient.
Respiratory sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no study available
Justification for classification or non-classification
Acid Blue 113 should be considered to be a sensitizer based on Regulation CE 1272/2008.
