Description of key information
The key study determined the potential of the read-across source substance (Benzenesulfonic acid, 4-C10-13-sec-alkyl derivs.-, compd. with 1-aminopropane-2-ol) to be sensitizing to skin. In a dermal sensitization study ten young adult Dunkin-Hartley guinea pigs were tested using the method of Magnusson and Kligmann according to OECD 406. In this study, the read across substance was not a dermal sensitizer.

- Executive summary:
In a dermal sensitization study with MARLON AMI 80 (78% benzenesulfonic acid, 4-C10-13-sec-alkyl derivs.-, compd. with isopropanolamine (1:1) in 22% 1,2-propylene glycol).Ten young adult Dunkin-Hartley guinea pigswere tested using the method of Magnusson and Kligmann according to OECD 406.α-Hexylcinnamaldehyde was used as apositive control material. No cutaneous reaction attributable to allergy was recorded in animals from the treated group after the challenge phase, with the test item at 1% and 0.5%. No cutaneous intolerance reaction was recorded in animals from the negative control group after thechallenge phase, on the treated area with the test item at 1% and 0.5%.
In this study, MARLON AMI 80 and hence,benzenesulfonic acid, 4-C10-13-sec-alkyl derivs.-, compd. with isopropanolamine (1:1) is not a dermal sensitizer.
