CAS: 110-44-1 INCI: Sorbic acid Chemical Structure: * Sorbic acid is a natural organic compound with the chemical formula C6H8O2. It is a derivative of acrylic acid. Source: * Originally isolated from the berries of the mountain ash tree (Sorbus aucuparia), sorbic acid is now typically produced synthetically for commercial use. Physical Form: * Sorbic acid is generally found as a white crystalline powder or granules. It is soluble in water and has a slightly bitter taste. Function and Uses: * Preservative: Sorbic acid is widely used as a preservative in the food, cosmetic, and pharmaceutical industries. It inhibits the growth of molds, yeasts, and some bacteria, thereby extending the shelf life of products. * Anti-Microbial Properties: Its antimicrobial properties make it effective in preventing spoilage and deterioration of products by microorganisms. * Food Preservation: Sorbic acid is commonly employed in food products, such as baked goods, dairy products, beverages, and condiments, to prevent microbial contamination. * Cosmetic Formulations: In cosmetics and personal care products, sorbic acid may be used as a preservative to maintain product integrity and prevent microbial growth. Common Applications: * Sorbic acid is utilized in various industries, including food and beverages, cosmetics, pharmaceuticals, and personal care products. Benefits: * Broad-Spectrum Preservative: Sorbic acid has broad-spectrum efficacy against a range of microorganisms, making it suitable for preventing spoilage in different products. * Stability: It contributes to the stability of formulations by preventing microbial contamination, which is particularly important in products with water content. * Odorless and Colorless: Sorbic acid is generally odorless and colorless, making it suitable for formulations where these characteristics are desired. Considerations: * While sorbic acid is considered safe for use as a preservative, regulatory guidelines dictate permissible concentrations in different products. * Some individuals may be sensitive to sorbic acid, and patch testing is recommended, especially for those with skin sensitivities. Regulatory Status: * Sorbic acid is approved for use as a food preservative and is generally recognized as safe (GRAS) by regulatory authorities. It is also accepted as a preservative in cosmetics and personal care products. Usage Instructions: * Sorbic acid is typically added to formulations at specific concentrations based on regulatory guidelines and the desired preservative effect. * Manufacturers follow recommended usage levels to ensure efficacy and safety in various products.
