E392 is the EU food additive number for rosemary extracts (Regulation (EU) No 1129/2011). It applies specifically to rosemary extracts and does not extend to sage extracts.

Which parameter is the extract standardized to?

By carnosic acid (CAS 3650-09-7): >10% by HPLC, with carnosol (CAS 5957-80-2) below 1%.

Will the extract impart a rosemary aroma to the product?

The sum of volatiles (borneol, bornyl acetate, camphor, 1,8-cineole, verbenone) is kept below 0.5%, so the sensory impact on the formulation is minimal.

What is the typical dosage?

In food applications, 0.05-0.5% by weight depending on the product category. The exact value is determined by the formulation and applicable regulation.

What documents are provided?

The technical data sheet (TDS) and safety data sheet (MSDS) are available on the product page. The batch certificate of analysis (COA) is provided on request together with a sample.

About

Rosemary Antioxidant Extract is a dark-brown, viscous solution of supercritical CO₂ extract from Rosmarinus officinalis leaves in deodorised sunflower oil, standardised to more than 10% carnosic acid (CAS 3650-09-7), with carnosol (CAS 5957-80-2) below 1%. E392 is the EU food additive number for rosemary extracts.

Functional Properties

Carnosic acid is a phenolic diterpene with potent antioxidant activity—it scavenges free radicals and inhibits lipid peroxidation. This antioxidant-focused variant has minimal volatile content (<0.5%), making it odourless and suitable for applications where rosemary aroma is undesirable.

Quality

Supercritical CO₂ extraction yields a solvent-free extract, supplied in deodorised sunflower oil with no additives. Heavy metals non-detectable. HPLC-verified carnosic acid content. Oil-soluble, insoluble in water.

Applications

Food & Beverage (E392): Oils 0.05%, meat 0.04%, sauces 0.10%, seasonings 0.20%, supplements 0.40%
Nutraceuticals: Cognitive support, neuroprotective formulations
Cosmetics: Anti-aging products, natural preservation systems
