Applicant's summary and conclusion

Interpretation of results:
slightly irritating
Remarks:
Migrated information primary dermal irritation index (PDII) value 2.56 Criteria used for interpretation of results: EU
Conclusions:
The primary dermal irritation index (PDII) from QSAR predicted a skin irritation score for the chemical 4-(2,6,6-trimethylcyclohex-1-ene-1-yl)-but-3-ene-2-one estimated as being equal to 2.56. This score indicated that 4-(2,6,6-trimethylcyclohex-1-ene-1-yl)-but-3-ene-2-one is mild irritating to the skin of human. However, this value is considered to be on the lower side not sufficient to qualify the chemical as a skin irritant.
Executive summary:

The primary dermal irritation index (PDII) from QSAR predicted a skin irritation score for the chemical 4-(2,6,6-trimethylcyclohex-1-ene-1-yl)-but-3-ene-2-one estimated as being equal to 2.56. This score indicated that 4-(2,6,6-trimethylcyclohex-1-ene-1-yl)-but-3-ene-2-one is mild irritating to the skin of human. However, this value is considered to be on the lower side not sufficient to qualify the chemical as a skin irritant.
