Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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.

Skin sensitisation

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not sensitising)
Additional information:

Concerning sensitisation one study in animals performed according to current standards and a study performed under GLP conditions were available. DBP did not reveal skin sensitising properties in these animal studies.

The available case studies in man are not appropriate for a definite conclusion with respect to the possible induction of sensitization by DBP. (1)

No signs of sensitisation were observed for DBP treatment in two guinea pig maximisation studies performed according to OECD Guideline 406 and a GLP-approved FDA recommended method (Greenough et al. 1981*; BASF 1990c*).

Similarly, no sensitisation was observed in a non-GLP repeated patch test in rabbits (BASF 1957*). (2)

Overall, DBP is not expected to have eye or skin irritation, or skin sensitising potential, in humans. (2, p.82)
