Extraction Technology: Solvent-Free Triple-Stage Filtration
💬 Technical Insight
"Our extraction process eliminates organic solvent use entirely by relying on a three-stage membrane microfiltration system combined with macroporous resin adsorption. This approach not only prevents solvent residue contamination but also allows precise control over impurity profiles, which is critical for cosmetic-grade applications where dermal safety is non-negotiable."
— Blue Eye Bio R&D Team
Unlike conventional ethanol or ethyl acetate extraction methods that require post-extraction solvent stripping and carry inherent residue risk, Blue Eye Bio's aqueous-based, solvent-free process removes this variable at the source. The three-stage microfiltration sequence progressively removes cellulose fragments, chlorophyll, and tannin impurities, while macroporous resin adsorption selectively concentrates catechin fractions — resulting in a final EGCG purity of 98.5%+ without introducing residual solvent risk.
Formulation Guidance for Cosmetic & Nutraceutical Applications
For formulators working with high-purity EGCG in topical or oral delivery systems, the following practical considerations apply:
- pH Stability Range: EGCG exhibits optimal stability at pH 3.5–5.5; formulations outside this range may accelerate oxidative degradation.
- Anti-Oxidation Strategy: Co-formulation with citric acid or ascorbic acid (Vitamin C) as chelating/antioxidant agents is recommended to minimize browning and catechin oxidation during shelf life.
- Light & Heat Sensitivity: Store and process below 25°C, away from direct light exposure, to preserve catechin structural integrity.
- Solubility Consideration: Given the solvent-free extraction profile, this grade demonstrates consistent aqueous solubility suitable for water-based serums, functional beverages, and capsule fill formulations.
Regulatory & Quality Compliance
