Description of key information
Data available for the structurally and functionally similar read across chemicals has been reviewed to determine the skin sensitization potential of the test chemical Reaction mass of 1-Propanaminium, 3-[[2-cyano-3-[4-(diethylamino)phenyl]-1-oxo-2-propen-1-yl]oxy]-N-[2-[[2-cyano-3-[4-(diethylamino)phenyl]-1-oxo-2-propen-1-yl]oxy]ethyl]-N,N-dimethyl- & chloride . The studies are as mentioned below:
The skin sanitization study of read across chemical was conducted by a safety assessment report in 10 female guinea pigs to determine its sensitization potential. The study was conducted according to OECD 406 Guidelines. For intradermal induction, the test animals received 6 injections (2 injections of a 0.1 ml Freund’s adjuvant/aqua dest 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 dest 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. A challenge with a 25% test substance preparation in olive oil was performed 14 days after the epicutaneous induction. No skin reactions could be observed neither in control group nor in the test group, 24 and 48 hours after removal of the patches. Olive oil, which was applied as a vehicle control to all animals, did not cause any skin reactions. Since no borderline results were observed, a 2nd challenge was not performed. Therefore, it was concluded that the test substance does not have a sensitizing effect on the skin of the guinea pig in the Maximization Test.
The above result was further supported by the dermal sensitization study of another read across chemical in guinea pigs. The study was performed as per OECD 406 Guidelines. 10 female were used for and 5 female Himalayan spotted guinea pigs were used in the test and control groups respectively. In induction treatment, 10 females in test group, 5 females in control group were used. Animals were induced with intradermal induction of Freund´s Complete Adjuvant (FCA) and physiological saline (1:1), test item at 5% in 1 % CMC and 5 % dilution of the test item in 1% CMC in a 1:1 mixture with FCA / physiological saline on day 1. After 7 days, epidermal induction of sensitization (day 8) was conducted under occlusion with the test item at 50 % in 1 % CMC for 48 hours. The challenge was performed at day 22 by application of the test item at 10 % in 1 % CMC under occlusive patch for 24 h at a different part of the skin. Observations were made at 24 and 48 hours removal of the dressing. After challenge exposure, no skin reactions were observed. Hence, sodium the test chemical was considered to be non-sensitizing to the Himalayan spotted albino guinea pigs.
Based on the above summarized studies for target chemical Reaction mass of 1-Propanaminium, 3-[[2-cyano-3-[4-(diethylamino)phenyl]-1-oxo-2-propen-1-yl]oxy]-N-[2-[[2-cyano-3-[4-(diethylamino)phenyl]-1-oxo-2-propen-1-yl]oxy]ethyl]-N,N-dimethyl- & chloride and its structurally and functionally similar read across substances,it can be concluded that the testchemical is unable to cause skin sensitization and considered as non-skin sensitizer. Comparing the above annotations with the criteria of CLP regulation, it can be classified under the category “Not Classified”.

- Executive summary:
Data available for the structurally and functionally similar read across chemicals has been reviewed to determine the skin sensitization potential of the test chemical Reaction mass of 1-Propanaminium, 3-[[2-cyano-3-[4-(diethylamino)phenyl]-1-oxo-2-propen-1-yl]oxy]-N-[2-[[2-cyano-3-[4-(diethylamino)phenyl]-1-oxo-2-propen-1-yl]oxy]ethyl]-N,N-dimethyl- & chloride. The studies are as mentioned below:
The skin sanitization study of read across chemical was conducted by a safety assessment report in 10 female guinea pigs to determine its sensitization potential. The study was conducted according to OECD 406 Guidelines. For intradermal induction, the test animals received 6 injections (2 injections of a 0.1 ml Freund’s adjuvant/aqua dest 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 dest 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. A challenge with a 25% test substance preparation in olive oil was performed 14 days after the epicutaneous induction. No skin reactions could be observed neither in control group nor in the test group, 24 and 48 hours after removal of the patches. Olive oil, which was applied as a vehicle control to all animals, did not cause any skin reactions. Since no borderline results were observed, a 2nd challenge was not performed. Therefore, it was concluded that the test substance does not have a sensitizing effect on the skin of the guinea pig in the Maximization Test.
The above result was further supported by the dermal sensitization study of another read across chemical in guinea pigs. The study was performed as per OECD 406 Guidelines. 10 female were used for and 5 female Himalayan spotted guinea pigs were used in the test and control groups respectively. In induction treatment, 10 females in test group, 5 females in control group were used. Animals were induced with intradermal induction of Freund´s Complete Adjuvant (FCA) and physiological saline (1:1), test item at 5% in 1 % CMC and 5 % dilution of the test item in 1% CMC in a 1:1 mixture with FCA / physiological saline on day 1. After 7 days, epidermal induction of sensitization (day 8) was conducted under occlusion with the test item at 50 % in 1 % CMC for 48 hours. The challenge was performed at day 22 by application of the test item at 10 % in 1 % CMC under occlusive patch for 24 h at a different part of the skin. Observations were made at 24 and 48 hours removal of the dressing. After challenge exposure, no skin reactions were observed. Hence, sodium the test chemical was considered to be non-sensitizing to the Himalayan spotted albino guinea pigs.
Based on the above summarized studies for target chemical Reaction mass of 1-Propanaminium, 3-[[2-cyano-3-[4-(diethylamino)phenyl]-1-oxo-2-propen-1-yl]oxy]-N-[2-[[2-cyano-3-[4-(diethylamino)phenyl]-1-oxo-2-propen-1-yl]oxy]ethyl]-N,N-dimethyl- & chloride and its structurally and functionally similar read across substances,it can be concluded that the testchemical is unable to cause skin sensitization and considered as non-skin sensitizer. Comparing the above annotations with the criteria of CLP regulation, it can be classified under the category “Not Classified”.
