Identity
Also known as: Benzoic acid, 4-hydroxy-, methyl ester, Benzoic acid, p-hydroxy-, methyl ester, p-Hydroxybenzoic acid methyl ester, Maseptol, Methylben, Methyl chemosept, Methylparaben, Methyl Parasept, Metoxyde, Moldex, Nipagin, Paridol.
Can Methyl P-Hydroxybenzoate be labeled natural?
Since Methyl P-Hydroxybenzoate is found in nature, US labeling follows how it was obtained: natural flavor from a natural source and a natural process, artificial when Methyl P-Hydroxybenzoate is synthesized. The EU and UK follow the same logic without a middle class; Mercosur and Mexico label synthetic Methyl P-Hydroxybenzoate identical-to-natural.
- 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
Methyl P-Hydroxybenzoate is FEMA GRAS under FEMA number 2710. 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 Methyl P-Hydroxybenzoate. 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)
Methyl P-Hydroxybenzoate 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. Methyl P-Hydroxybenzoate appears on the EPA Toxic Substances Control Act Chemical Substance Inventory under CAS 99-76-3, where EPA names it Benzoic acid, 4-hydroxy-, methyl ester.
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.

Methyl P-Hydroxybenzoate FAQ
Does Methyl P-Hydroxybenzoate have FEMA GRAS status?
Methyl P-Hydroxybenzoate holds FEMA GRAS status under FEMA number 2710. It is also codified at 21 CFR 172.515.
How do I cite Methyl P-Hydroxybenzoate by FEMA or CAS number?
Cite Methyl P-Hydroxybenzoate as FEMA 2710 or CAS 99-76-3; both point to the same entry.
Can Methyl P-Hydroxybenzoate be labeled a natural flavor?
Methyl P-Hydroxybenzoate occurs in nature, so the label depends on the route: Methyl P-Hydroxybenzoate won from a natural source by a physical, enzymatic or microbiological process is natural flavor in the United States, and synthesized Methyl P-Hydroxybenzoate is artificial. The EU and UK grant the natural claim only to that natural route; Mercosur and Mexico call synthetic material identical-to-natural.

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 METHYL P-HYDROXYBENZOATE under CAS 99-76-3 and carries its FEMA number and its 21 CFR citations. The inventory is searchable at FDA. FDA records its technical effect as antimicrobial agent, 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.
