Skin sensitization
Various studies for target (Solvent Red 49, CASno-509-34-2) and its read across were summarized as follows:
The skin sensitizing potential for Solvent Red 49 (509-34-2) is estimated using OECD QSAR toolbox version 3.4.The test substance Solvent Red 49 is estimated to be not sensitizing in guinea pig.
In other study by (Guin JD, 2003) with similar substance (509-47-8) was observed in human .The sensitization potential of D&C yellow 8 was determined by performing patch tests on humans. The dye was applied in Finn Chambers and read first at 2 or (more commonly) 3 days and again at 4–7 days. The reactions of the patients were graded as ‘? + ‘ , ‘+’ and ‘++’ categories 16 patients were tested with the dye. As only 1 positive reaction was reported by a patient. D&C yellow 8 can be considered as a non- sensitizer in humans. Therefore D&C yellow 8 can be considered as a non- sensitizer in humans.
In other study by (E. Nucera, D. Schiavino et al., 2003) with similar substance (509-47-8) was observed in human. Patch test was conducted on 1 human male patient to evaluate skin sensitising potency of chemical sodium Fluorescein. An allergological evaluation (patch tests) with 20% sodium Fluorescein was performed. Saline and histamine solutions were used, respectively, as negative and positive controls .The patch test result was negative. Hence, Non-sensitising effects were observed in patch test conducted on human male patient applied with 20% sodium Fluorescein .Therefore sodium Fluorescein was considered to be a non sensitizing in human.
In another study by (SCIENTIFIC COMMITTEE ON CONSUMER PRODUCTS (SCCP), 2006)with similar substance (302776-68-7) was observed in guinea pigs. The skin sanitization test of Diethylamino hydroxybenzoyl hexyl benzoate(CAS No: -302776-68-7)was conducted in 10 female guinea pigs to determine its sensitization potential. For intradermal induction, the test animals received 6 injections (2 injections of a 0.1 ml Freund’s adjuvant/aqua test 1:1, 2 injections of 0.1 ml of a 5% test substance formulation, 2 injections of a 0.1 ml 5% test substance formulation in Freund’s adjuvant/aqua test 1:1). The intradermal induction with 5% test substance preparations caused moderate and confluent erythema and swelling or intense erythema and swelling in test group animals at 24 h after application.Percutaneous induction was carried out 1 week after intradermal induction. The test substance (25% in olive oil) and the vehicle were applied for 48 h to the animals under occlusive conditions. Incrustation, erythema and oedema were observed in test and control animals at 48 h after beginning of application. After the epicutaneous induction, incrustation, partially open (caused by the intradermal induction) could be observed in addition to moderate and confluent erythema and swelling in all test groups animals.
On the basis of available information for the target as well as read across substance and applying weight of evidence approach, the test substance can be considered as not sensitising to the skin.
