Ellagic Acid 98%

Ellagic Acid 98% is a high-purity polyphenolic phytochemical supplied as a concentrated powder ingredient. Ellagic acid is a naturally occurring phenolic compound associated with ellagitannin-rich plant materials and has the molecular formula C14H6O8. The purified ingredient is commercially distinct from conventional botanical powders and lower-assay standardized extracts.

Essencefield offers the 98% grade for formulation and ingredient sourcing projects, with HPLC used for quantitative assay. This concentrated format is selected when formulators require a defined ellagic acid input rather than the broader polyphenol profile of a botanical extract. Low aqueous solubility is an important consideration during product development and delivery-system selection.

Ingredient Profile & Common Uses

Ellagic acid is a defined polyphenolic compound with CAS No. 476-66-4 and a molecular weight of 302.19 g/mol. Chemically, it is a polyphenolic dilactone associated with ellagitannin chemistry. Unlike pomegranate powder or a standardized botanical extract, the 98% material is positioned as a concentrated individual phytochemical in which compound purity is the primary commercial specification.

The 98% HPLC grade represents the main high-purity form used when buyers need controlled active loading. Lower-assay botanical materials may contain ellagic acid together with tannins, punicalagins, other polyphenols, carriers, and naturally occurring plant constituents. The purified grade therefore serves a different procurement and formulation purpose from lower-standardized extract formats.

Commercial use is concentrated in dietary supplement, functional ingredient, phytochemical blend, and selected cosmetic formulation projects. The compound is poorly soluble in water, while published data show greater solubility as pH increases. Formulators should therefore consider dispersion, dissolution, precipitation, and ingredient distribution rather than treating the powder as freely water soluble.

Application Areas

Dietary Supplement Formulations

Used in capsules, tablets, powders, and concentrated supplement blends where a defined phytochemical input is preferred over a multi-component botanical extract.

Functional Nutrition Products

Suitable for dry functional nutrition systems and concentrated premixes. Water-based applications require additional evaluation because native ellagic acid has very low aqueous solubility.

Phytochemical & Polyphenol Blends

Used alongside other defined botanical compounds where formulation teams need control over individual phytochemical loading, blend composition, and low-inclusion premixing.

Cosmetic & Personal Care Formulations

Used as a defined polyphenolic ingredient in selected topical and cosmetic development projects, with solvent compatibility, dispersion, pH, and precipitation behavior evaluated during formulation.

Compound Identity & Purity

Ellagic acid has a rigid fused aromatic structure containing four phenolic hydroxyl groups and two lactone groups. This structure contributes to strong intermolecular association and limited aqueous solubility, both of which are relevant to ingredient handling and formulation behavior.

For procurement, a 98% material should be distinguished from botanical extracts standardized to lower ellagic acid concentrations. The purified form is purchased primarily as a defined phytochemical, while a botanical extract remains a multi-component matrix containing additional tannins, polyphenols, and plant-derived constituents.

HPLC is therefore central to evaluating the high-assay grade because it measures the individual compound rather than a broader total-polyphenol or total-tannin fraction. The CAS 476-66-4 material has the molecular formula C14H6O8 and molecular weight 302.19 g/mol; separately listed hydrated forms should be treated as different specification entities during technical comparison.

Technical & Quality Considerations

Analytical evaluation should prioritize compound identity, HPLC assay, and correct interpretation of reported purity. An individual-compound chromatographic assay provides more procurement value than generic measurements of total polyphenols because the two methods quantify different analytical targets. This distinction is especially important when comparing purified material with standardized botanical products.

The compound is characteristically difficult to dissolve in water. Published equilibrium-solubility data report approximately 9.7 μg/mL in water and 33.1 μg/mL in pH 7.4 phosphate buffer. Solubility increases with increasing pH, and reference-grade material has also been reported at 10 mg/mL in 1 M sodium hydroxide. These properties explain why the standard powder should not be assumed to form a clear aqueous solution.

During dry-product scale-up, R&D should evaluate premixing and blend uniformity because concentrated phytochemicals may be incorporated at relatively low inclusion levels. In liquid and semi-solid systems, wetting, dispersion, pH, solvent selection, precipitation, and physical stability become more important. A water-dispersible, micronized, complexed, or otherwise delivery-enhanced ingredient should be treated as a separate formulation format rather than assumed to behave like the standard powder grade.
