p-Anisic Acid

p-Anisic Acid (CAS 100-09-4), also recognized by its FEMA 3945 designation, is an aromatic organic acid derived from anise that delivers a characteristic sweet, floral-herbal note in flavor and fragrance applications. It functions as a flavoring agent, mild preservative, and pH modifier across pharmaceutical, cosmetic, and food manufacturing. In flavor formulations, it contributes anise-like top notes to confectionery and baked goods.

It is also used in beverage products where natural-profile aromatics are required. Cosmetic and personal care formulators incorporate it as a preservative booster and fragrance fixative in creams, lotions, and rinse-off products. Pharmaceutical manufacturers use it as an intermediate in synthesizing active ingredients and as a mild antimicrobial agent in topical preparations. In food-grade applications, it supports pH regulation in acidified products.

This is particularly useful where both buffering capacity and flavor contribution are commercially desirable. p-Anisic Acid is supplied as a white to off-white crystalline powder for various industrial uses. Food and flavor grades conforming to FEMA 3945 standards are the most common commercial forms. Pharmaceutical-grade material is also available to USP and BP specifications for high-purity requirements.

Packaging typically ranges from kilogram quantities for specialty formulators to bulk drum supply for industrial buyers. This ensures consistent quality and availability for large-scale manufacturing operations worldwide.
