Ellagic acid

Ellagic acid (CAS 476-66-4) is a naturally derived polyphenol extracted primarily from pomegranate, oak galls, and other tannin-rich plant sources. In food and cosmetic manufacturing, it functions as an antioxidant and skin-brightening active. This versatile compound protects formulations and finished products from oxidative degradation. In cosmetic formulations, it is incorporated into serums, creams, and spot-treatment products targeting hyperpigmentation.

The ingredient inhibits melanin synthesis to deliver a measurable brightening effect. Food manufacturers use it as a natural antioxidant to extend shelf life in functional beverages, nutraceutical supplements, and fortified food products. In dietary supplement production, it is supplied as a standardized botanical extract. It is positioned as a premium plant-based antioxidant ingredient for capsule and tablet formats to meet consumer demand for natural labels.

Cosmetic formulators also apply it in anti-aging product lines where oxidative stress protection is a key performance claim. The material is available as a fine yellow powder, typically supplied as a standardized extract. Defined polyphenol content ranges from 40% to 98% purity depending on the application. Food-grade and cosmetic-grade specifications are the most commercially prevalent for industrial use and product development.

High-purity grades are suitable for nutraceutical and premium skincare applications. Bulk quantities are available for industrial formulators, with smaller quantities offered for R&D and pilot-scale production needs.
