The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

adverse effect observed (sensitising)
Additional information:

The delayed contact hypersensivity of 3-isopropoxypropylamine (IPOPA) was evaluated in Guinea pigs according a protocol similar to OECD N°406 guideline (Magnusson and Kligman test) (Manciaux, 1998b). The induction phase has been realized both by intradermal route on day 1 (IPOPA 0.1% in vehicle) and by cutaneous route on day 8 (IPOPA 25%) in 2 groups of guinea pigs: 5 males and 5 females for control group and 10 males and 10 females for treated group. The challenge phase was realized on day 22 by cutaneous application of IPOPA 10%; the cutaneous reactions were scored 24 and 48 hours after the challenge phase. No cutaneous reaction was observed in the animals of the control group. In the treated group, a very slight or well-defined erythema (grade 1 or 2) was noted at the 24hour reading in 6/20 and 13/20 guinea pigs respectively. A slight oedema (grade 2) was recorded in 3/20 animals. At the 48hour reading, a very slight or well-defined erythema (grade 1 or 2) persisted in 5/20 and 1/20 animals respectively. Dryness of the skin was observed in 14/20 animals and crusts were noted in one animal. 3-isoproxypropylamine induces delayed contact hypersensitivity in 65% and should be considered as a strong sensitizing.
