Evaluations

Evaluation year: 2000

ADI:
0-0.4 mg/kg bw (1999)

Comments:
No safety concern at current levels of intake when used as a flavouring agent. In 1999 JMPR allocated an ADI of 0-0.4 mg/kg bw for 2-phenylphenol; an ADI was not established for the sodium salt because it rapidly dissociates to 2-phenylphenol (FAO Plant Production and Protection Paper 153, Rome, 1999)
