Description
P-Anisic acid (CAS 100-09-4) is a naturally occurring aromatic acid derived from anise, also known as anisic acid, NSC 7926, and FEMA 3945. It carries no assigned E-code in the EU but is recognised under FEMA for flavour applications. Its molecular formula is C8H8O3.
In food and cosmetic formulations, p-anisic acid functions as an antimicrobial preservative by disrupting microbial cell membranes, inhibiting bacterial and fungal growth at low concentrations. It also serves as a pH buffer and acidulant in flavour systems, contributing a mild anise-like character to food and beverage products.
P-Anisic acid is available in powder form to food-grade and cosmetic-grade specifications, with compliance applicable under REACH regulation for EU market supply. It falls under HS code 29189090 for import and export classification. Procurement teams should confirm grade suitability against FCC or Ph.Eur. standards depending on the target application.
