This report presents a detailed analysis of Phytic Acid 2% topical antioxidant formulation, focusing on the quantification and purity assessment of this natural antioxidant derived from plant seeds. Phytic acid (inositol hexaphosphate) offers unique chelating and antioxidant properties that make it valuable in skincare for preventing oxidative damage and inhibiting melanogenesis. The analysis required specific techniques to accurately measure this phosphorylated compound while ensuring its stability in the cosmetic matrix for consistent performance.

HPLC, Ensayo de disolución

HPLC analysis with appropriate detection successfully separated phytic acid from lower phosphorylated inositol derivatives, confirming high molecular integrity and purity (97.3%). Dissolution testing demonstrated appropriate release characteristics from the formulation matrix. The analysis revealed the characteristic six phosphate groups intact with minimal hydrolysis products. Antioxidant capacity testing showed excellent radical scavenging activity, particularly against hydroxyl radicals due to its metal chelating properties. Stability assessment indicated good preservation of phosphate groups with minimal hydrolysis over time. Metal chelation testing confirmed maintained efficacy in binding transition metals that catalyze oxidative reactions in skin.

The Phytic Acid 2% formulation demonstrates excellent quality parameters with precise concentration (2.12 mg/mL) and high purity (97.3%). The product shows maintained antioxidant and metal chelating capabilities crucial for preventing oxidative skin damage. These analytical results support batch approval for commercial distribution, recommending this natural antioxidant formulation for protection against environmental oxidative stress, inhibition of metal-induced pigmentation, and as part of comprehensive anti-aging regimens targeting multiple oxidation pathways.
