Can Bornyl butyrate be labeled natural?

The process decides for bornyl butyrate. It occurs in nature, so a natural-source, natural-process material is natural flavor in the US and synthetic bornyl butyrate is artificial. In the EU and UK the natural claim likewise needs the natural route, while Mercosur and Mexico keep a third class, identical-to-natural, for the synthetic material.

United States
Natural or artificial, by process
European Union and UK
Natural only from natural material
Mercosur and Mexico
Natural or identical-to-natural

How each market defines the classes: natural vs artificial flavor under 21 CFR 101.22.

Regulatory status, with citations

United States

Bornyl butyrate is FEMA GRAS under FEMA number 3907. It is cited in the Code of Federal Regulations at 21 CFR 172.515.

Not on the California Proposition 65 list.

TSCA Inventory status

A flavor ingredient is also an industrial chemical. Bornyl butyrate appears on the EPA Toxic Substances Control Act Chemical Substance Inventory under CAS 13109-70-1, where EPA names it Butanoic acid, (1R,2S,4R)-1,7,7-trimethylbicyclo[2.2.1]hept-2-yl ester, rel-.

Inactive in US commerce

EPA designates this substance inactive, so a Notice of Activity Form B is required before anyone manufactures or processes it again. Being FEMA GRAS does not change that. What active and inactive mean.

Sources and attribution. The identity and regulatory facts on this page are taken from the FDA Substances Added to Food inventory, a US government record, which lists this substance as BORNYL BUTYRATE under CAS 13109-70-1 and carries its FEMA number, its JECFA flavor number. The inventory is searchable at FDA. FDA records its technical effect as flavoring agent or adjuvant.

A FEMA GRAS conclusion is reached by the Expert Panel of the Flavor and Extract Manufacturers Association of the United States, and the FEMA number names that conclusion. FEMA publishes its own entry for this substance in the FEMA Flavor Library, which is the authoritative record of what the Panel decided and is worth reading alongside this page.
