Interpretation of results:
not sensitising
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Three positive reactions observed from a total 112 patients with eczematous dermatitis patch-tested with 2% butylated hydroxyanisole.From this test result it is concluded that tert-butyl-4-methoxyphenol was not found to be sensitising to human skin.
Executive summary:

Three positive reactions observed from a total 112 patients with eczematous dermatitis patch-tested with 2% butylated hydroxyanisole.From this test result it is concluded that tert-butyl-4-methoxyphenol was not found to be sensitising to human skin.

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

Three positive reactions observed from a total 112 patients with eczematous dermatitis patch-tested with 2% butylated hydroxyanisole.From this test result it is concluded that tert-butyl-4-methoxyphenol was not found to be sensitising to human skin.

The other authoritative supporting sources of information also indicates that the tert-butyl-4-methoxyphenol was not found to be sensitising.
