Chemical Properties Of Sorbic acid Cas 110-44-1

  • Sorbic acid (2,4-hexadienoic acid) is a highly effective, low-toxicity, naturally sourced acidic food preservative. Its molecular formula is C₆H₈O₂, molecular weight 112.12, and it is classified as a ‘safe-grade’ preservative by the Food and Agriculture Organisation of the United Nations and the World Health Organisation. It exhibits excellent stability and safety, with its primary function being to inhibit microbial growth and reproduction, thereby extending product shelf life. It finds extensive application across food, pharmaceutical, and daily chemical industries.
  • Sorbic acid possesses a unique characteristic absent in other preservatives: strong preservative selectivity. It effectively suppresses the growth of bacteria harmful to humans while remaining harmless to beneficial bacteria.

Product Application Of Sorbic acid Cas 110-44-1

  • Sorbic acid is extensively used in perishable foods such as baked goods, processed fruits and vegetables, beverages, dairy products, and meat preparations. It preserves original flavour profiles while offering high safety margins.
  • Within pharmaceutical applications, sorbic acid primarily functions as an excipient (preservative) in liquid or semi-solid formulations. It prevents microbial contamination that could compromise drug integrity, thereby ensuring therapeutic safety.
  • Owing to its mild, low-irritant properties, sorbic acid frequently serves as an auxiliary or primary preservative in personal care products such as skincare, oral hygiene items, shampoos, and other toiletries. It is also employed to preserve cosmetic ingredients, including natural plant extracts.
  • Employed in livestock and poultry feed (e.g., piglet feed, layer feed) or aquatic feed (e.g., fish feed) to inhibit mould growth, extend feed shelf life, and safeguard animal health.
