Regulatory status, with citations
United States
Rum ether is FEMA GRAS under FEMA number 2996. It is cited in the Code of Federal Regulations at 21 CFR 172.515.
European Union and United Kingdom
No EU FL number is on file for Rum ether. That is not a finding either way. The Union List covers defined flavouring substances, so natural complex materials are handled as flavouring preparations under Parts B to F and never receive a number, and substances used as additives sit under Regulation 1333/2008 instead. Confirm the position before EU or UK use.
JECFA (WHO / FAO)
Rum ether has not been evaluated by JECFA as a flavouring agent, or no evaluation is on file.
Other US flags
Not on the California Proposition 65 list.
TSCA Inventory status
A flavor ingredient is also an industrial chemical. Rum ether appears on the EPA Toxic Substances Control Act Chemical Substance Inventory under CAS 8030-89-5, where EPA names it Pyroligneous acids, reaction products with Et alc., distillates.
Active in US commerce
EPA designates this substance active, so no Notice of Activity Form B is required before manufacturing. What active and inactive mean.
EPA regulatory flags
| Flag | EPA definition | What it obliges |
|---|---|---|
| UVCB | The presence of "UVCB" indicates the substance is a Class 2 substance within the UVCB group, i.e. those with "unknown" or "variable composition," "complex reaction products" and "biological materials." | Care with identity. A UVCB has no definite molecular formula, so its identity rests on the process and the feedstock. Two suppliers can ship materially different material under one CAS number. |
