Sorbic Acid

overview

Sorbic Acid is a naturally occurring compound used as a preservative in cosmetics, personal care products, foods, animal feeds, and pharmaceutical drugs. It is effective against fungi and yeast but less effective against bacteria. It is derived from the berries of the mountain ash tree, Sorbus aucuparia, Rosaceae, or synthesized by various processes. It is relatively safe for the skin, but may cause mild irritation in those who have an allergy to it. Sorbic Acid is also used as a humectant to keep the moisture within the product and avoid it drying out and becoming unusable.

Skin suitability

Suitable for sensitive skin with caution

concerns

Sorbic Acid and Potassium Sorbate are practically nontoxic in acute oral toxicity studies. In subchronic studies, no significant adverse effects were observed when 10% Sorbic Acid was included in the diet. Sorbic Acid and Potassium Sorbate, at concentrations up to 10%, were practically nonirritating to the eye. Both ingredients at concentrations up to 10% were at most only slightly irritating to skin. However, other studies published by the CIR found Sorbic Acid to be practically nontoxic in acute oral toxicity studies, and no significant adverse effects were observed when 10% Sorbic Acid was included in the diet. "Sorbic Acid and Potassium Sorbate, at concentrations up to 10%, were practically nonirritating to the eye. Both ingredients at concentrations up to 10% were at most only slightly irritating to skin" (CosmeticsInfo.org).

precautions

People with eczema should avoid sorbic acid in cosmetics because of possible irritation, but avoiding it in foods is unnecessary. Concentrations of this ingredient should remain low - 0.05 percent to 0.3 percent are common concentrations of sorbic acid - to avoid irritation of the skin.

["Sorbic Acid is FDA approved and has received its GRAS (Generally Recognized as Safe) rating.", "Sorbic Acid is considered a moderate hazard ingredient by the Cosmetics Database, which notes concerns regarding cancer, allergic reactions, organ system toxicity, and irritation.", "In one or more in vitro tests, mammalian cells showed positive mutation results, and one or more animal studies showed skin irritation at very low doses; there is strong evidence that it is a human skin toxicant.", "Some molds (notably some Trichoderma and Penicillium strains) and yeasts are able to detoxify sorbates by decarboxylation, producing trans-1,3-pentadiene. The pentadiene manifests as a typical odor of kerosene or petroleum.", "Other detoxification reactions include reduction to 4-hexenol and 4-hexanoic acid"]
