Overview

E392 - Extracts of rosemary

Extracts of rosemary (E392) are natural antioxidants made from the leaves of the rosemary plant. They help keep fats and oils from going rancid, which can protect flavor, color, and nutrients in many foods. You’ll most often see them on labels as “rosemary extract” or “E 392.”

E217 - Sodium propyl para-hydroxybenzoate

Sodium propyl para-hydroxybenzoate (E217) is a preservative from the paraben family. It helps stop molds and yeasts from growing, which keeps foods fresher for longer. Rules for its use can differ by country, and labels may list it as “E217,” “sodium propyl paraben,” or “sodium propyl p-hydroxybenzoate.”

Popular questions

Yes—small amounts of rosemary extract (E392) used as a food preservative are generally safe for dogs; avoid giving concentrated essential oils and stop if stomach upset occurs.
Can dogs eat rosemary extract?
It’s commonly used in dog foods as a natural antioxidant and is considered safe at low levels, but consult your vet if your dog is prone to seizures or is pregnant/lactating.
Can cats have rosemary extract?
In the tiny amounts used as a preservative, rosemary extract is generally considered safe for cats; do not use rosemary essential oil, as cats are very sensitive to concentrated oils.
How to extract rosemary oil?
Rosemary essential oil is typically obtained by steam distillation of the herb, producing a highly concentrated oil that is not the same as E392 and isn’t intended for ingestion without expert guidance.
How to make rosemary extract?
Commercial E392 is made by extracting rosemary with food‑grade solvents (e.g., ethanol), then purifying and standardizing carnosic acid/carnosol levels; at home you can approximate it by steeping dried rosemary in high‑proof food‑grade alcohol and filtering, though it won’t be standardized.
