Safety in Use Information:
Category: flavor and fragrance agents
IFRA Critical Effect: Potential of nitrosamine formation
IFRA fragrance material specification:
 The material has been identified for having the potential of forming nitrosamines in nitrosating systems. Downstream users therefore have to be notified of the presence of the material and its potential to be able to consider adequate protective measures.
IFRA: View Standard
Recommendation for para-methyl tetrahydroquinoline usage levels up to:
  2.0000 % in the fragrance concentrate.
 
Maximised Survey-derived Daily Intakes (MSDI-EU): 0.012 (μg/capita/day)
Modified Theoretical Added Maximum Daily Intake (mTAMDI): 400 (μg/person/day)
Threshold of Concern:90 (μg/person/day)
 
Food categories according to Commission Regulation EC No. 1565/2000 (EC, 2000) in FGE.06 (EFSA, 2002a). According to the Industry the "normal" use is defined as the average of reported usages and "maximum use" is defined as the 95th percentile of reported usages (EFSA, 2002i).
Note: mg/kg = 0.001/1000 = 0.000001 = 1/1000000 = ppm.
