| Notes: | |||
| IFRA FLAVOR REQUIREMENTS: | |||
Due to the possible ingestion of small amounts of fragrance ingredients from their use in products in Categories 1 and 6, materials must not only comply with IFRA Standards but must also be recognized as safe as a flavoring ingredient as defined by the IOFI Code of Practice (www.iofi.org). For more details see chapter 1 of the Guidance for the use of IFRA Standards. | |||

| Maximised Survey-derived Daily Intakes (MSDI-USA): | 43.00 (μg/capita/day) | ||
| Structure Class: | I | ||
| Use levels for FEMA GRAS flavoring substances on which the FEMA Expert Panel based its judgments that the substances are generally recognized as safe (GRAS). | |||
| The Expert Panel also publishes separate extensive reviews of scientific information on all FEMA GRAS flavoring substances and can be found at FEMA Flavor Ingredient Library | |||
