SORBIC ACID
Commonly Found In
Overview
SORBIC ACID is a naturally occurring straight-chain unsaturated fatty acid first isolated from mountain ash berries (Sorbus aucuparia) in 1859, now commercially produced by chemical synthesis. In cosmetics, it is used as a preservative effective against molds, yeasts, and some bacteria. Unlike many other preservatives, sorbic acid is metabolized by the body in the same pathway as other fatty acids, making it one of the most toxicologically benign preservatives available. The EU permits it at a maximum of 0.6% in cosmetics; Japan and the US also allow its use. It functions best at acidic pH (below 6.5).
Also known as: Sorbic Acid, 2,4-Hexadienoic Acid, E200 (food additive), Sorbistat
Key Benefits
Sorbic acid functions as a preservative with antimicrobial properties. Studies confirm its effectiveness against molds and yeasts at low concentrations in acidic formulations. It does not provide direct skin-conditioning benefits but contributes to product safety and stability.

Strictness Ranking
πΏ Natural Sources
First isolated from rowan berries (Sorbus aucuparia) in 1859 by German chemist August Wilhelm von Hofmann. Also found naturally in some other fruits and berries.
π How It's Made
Synthesized from crotonaldehyde and ketene in a condensation reaction, followed by acid treatment. The process was first developed commercially in the 1940s for food preservation.
π Uses in Cosmetics
Used in cosmetic products primarily for fragrance, preservative.
π¬ Other Applications
Widely used as a food preservative (E200) in cheese, wine, baked goods, and dried fruits. Also used in pharmaceutical products, animal feed, and as a fungicide in agriculture.
π‘ Fun Facts
- β’ Sorbic acid was first discovered over 160 years ago but wasn't used commercially until the 1940s when food preservation became critical during World War II
- β’ It's one of the few preservatives that is metabolized by the body like a natural fatty acid, making it among the safest preservatives known
- β’ Despite being named after mountain ash berries, virtually all sorbic acid today is synthetically produced
