- RANGE FINDING TESTS:
Determination of the primary non-irritant concentration:
In a dermal-occlusive test for primary skin irritation, each of the following test concentrations was applied to the left flank of two guinea pigs:
25.0 % Remazol-Goldgelb RNL in vaseline
2.5 % Remazol-Goldgelb RNL in vaseline
0.25 % Remazol-Goldgelb RNL in vaseline
The hair on the left flanks of the animals was removed mechanically. 0.5 mL of the test substance preparation was applied to a 2 x 2 cm cellulose patch, which was then fixed to the left flank and covered occlusively for 24 hours with a bandage and film. 24 hours after removal of the patches, the treated skin areas were examined for erythema and oedema
Determination of the tolerance of intradermal injections:
To determine the tolerance of intradermal injections, each of the following preparations (5.0%, 1.0%, 0.25% in isotonic saline) was administered twice by intradermal injection to 3 guinea pigs. The injection sites (sites 1, 2 and 3) were all within a dorsal area measuring 2 x 4 cm in the vicinity of the shoulder.

- Evaluation (hr after challenge): 24 and 48 hours - Challenge controls:
- In addition to the control group, 5 further guinea pigs (attending group) were used to confirm that challenge exposure with 2.5% TS would not lead to dermal irritation in animals pre-treated with 50% FCA.

Classification: sensitizing - Executive summary:
Testing for sensitizing properties of Remazol Gelb RLN was performed in female Guinea pigs according to the method of MAGNUSSON & KLIGMAN. Intradermal induction was performed using 5% test substance in isotonic saline. Dermal induction and challenge treatment were carried out with 25% and 2.5% test substance in white vaseline.
Based on the results of this study Remazol Gelb RLN showed evidence for sensitizing properties.

Respiratory sensitisation
Endpoint conclusion
- Additional information:
The registered chemical is a reactive dye. For this class of dyes it was generally agreed between the members of the Ecological and Toxicological Association of Dyes and Organic Pigments Manufacturers (ETAD) that a possible risk for respiratory sensitisation for workers exists at high exposure. However the following should be noted:
1) For the substance no history of respiratory problems, such as occupational asthma, is associated with the manufacture and use of the specific substance.
2) Due to the granular form of the substance (spray dried in closed system from aqueous solution directly after synthesis) or the properly de-dusted powder no risk for inhalative exposure arises.
The potential to cause respiratory sensitisation is therefore not considered to be applicable for this substance.
No evidence of respiratory sensitisation was noted in any of the studies conducted, and it is proposed that the substance is not a respiratory sensitiser.
Migrated from Short description of key information:
Not assessed. No evidence of respiratory sensitisation was noted in any of the studies conducted, and it is proposed that the substance is not a respiratory sensitiser.
Justification for classification or non-classification
The above results triggered no classification under the Dangerous Substance Directive (67/548/EEC) and the CLP Regulation (EC No 1272/2008). No classification for sensitisation is therefore required.
CLP Regulation (EC No 1272/2008): Skin Sensitiser 1B – H317
