- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- In the experimental conditions described by OECD guideline 404 for evaluation of the acute dermal irritation / corrosivity of the substance Reactive Blue 198 is detemined to be not irritating to the skin.
- Executive summary:
About 24 hours before the start of the study the hair in the dorsal region of the body of 3 rabbits was removed with an electric clipper. Only animals with intact skin were used.
Each animal was treated with 0.5 g Reactive Blue 198 pasted with 0.4 mL deionised water. The substance was applied over the whole surface of a 2.5 x 2.5 cm covered by surgical gauze and a piece of impermeable rubber sheeting, secured with adhesive impermeable polyethylene tape
The exposure period was 4 hours. After the exposure period all remnants of the test substance were carefully removed from the skin with warm tap water.
Examinations of the skin took place after 30 - 60 minutes as well as 24, 48 and 72 hours after removal of the patches.
Erythema and oedema were evaluated numerically according to the score of DRAIZE. All other changes of the skin were recorded.
No signs of irritation occurred during the whole study.
The skin of the animals was discoloured blue 3 after removal of the patches up to the end of the study.
Testing of Reactive Blue 198 for primary dermal irritation in the rabbit showed, that the substance is not irritating to skin.
