Potassium sorbate is a widely used preservative in the cosmetic and skincare industry, valued for its effectiveness in preventing mold and yeast growth. Despite its popularity, many consumers wonder if potassium sorbate is safe for skin. This article explores its benefits, safety profile, and best practices for use.

What is Potassium Sorbate?

Potassium sorbate is the potassium salt of sorbic acid, commonly used in personal care products to extend shelf life. It is odorless, colorless, and highly effective in maintaining product integrity without compromising on skin-friendliness.

Potassium sorbate helps prevent spoilage by inhibiting mold, yeast, and fungi, ensuring that skincare products remain safe to use.

Is Potassium Sorbate Safe for Skin?

Potassium sorbate is widely used in cosmetics and personal care products as a preservative. The Cosmetic Ingredient Review (CIR) Expert Panel has scientifically evaluated data and decided that sorbic acid and potassium sorbate are safe for cosmetic and personal care product use.

Scientific evaluations by the Cosmetic Ingredient Review (CIR) panel confirm the safety of sorbic acid and potassium sorbate in various applications. Acute oral studies have proven sorbic acid and potassium sorbate to be practically nontoxic even on dietary concentrations that reach  up to 10%. Chronic tests also confirmed these compounds do not have carcinogenic effects when it comes to food intake, plus formulations with them at a 0.5% concentration were observed to be nontoxic and even non-sensitizing as well as not irritating according to Cosmetics Info.

However, some individuals may experience skin irritation or allergies when using products containing potassium sorbate. Healthline notes that while potassium sorbate is safe for most people, it may cause skin allergies in certain cases. Similarly, the Environmental Working Group (EWG) indicates that potassium sorbate has a moderate risk for allergies and immunotoxicity.
