	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.

Recommendation for 2-nonyn-1-al dimethyl acetal flavor usage levels up to:
	not for flavor use.
