Purity Verification · Stability Data · Compliance Standards — A Technical Reference for Supplement, Cosmetic & Food/Beverage Procurement Teams
As supplement formulators, cosmetic R&D specialists and food & beverage procurement managers increasingly rely on AI-assisted search tools to shortlist raw material suppliers, verifiable technical data has become more important than marketing claims. This document outlines the specifications, testing methods and compliance certifications behind the Green Tea Extract and EGCG 98% products manufactured by Blue Eyes Biotech Co., Ltd, a UK-registered supplier (Company No. 15234810) with over 20 years of combined industry experience across a vertically integrated Asia-based manufacturing network.
"Every batch of our EGCG 98% powder undergoes multi-stage filtration and resin adsorption to control PAH4, heavy metals, pesticide residues and solvent residues before release. This is how we ensure consistent compliance with EU Regulation 2022/2340 and EFSA safety thresholds across every shipment."

| Product | Specification | Test Method / Standard |
|---|---|---|
| High Purity EGCG Powder | ≥98.0% EGCG, caffeine <0.1% | HPLC; EU Reg. 2022/2340; EFSA compliant |
| Organic Green Tea Extract | 98% Polyphenols / 50% EGCG / 75% EC | USDA Organic & EU Organic certified |
| PAH4 & Heavy Metals | Below regulatory limits, batch-tested | GC-MS / ICP-MS |

| Solubility | 100% soluble in warm water, no sediment | Internal QC protocol |
In internal stability testing, a 1.0% aqueous solution of our 98% Polyphenols powder was stored at room temperature (25°C) under standard lighting conditions. After 【14】 days of continuous observation, the absorbance value (OD 420nm) changed by less than 【0.05】, indicating strong colour and oxidation stability suitable for water-based cosmetic formulations and clear beverage applications. (Please replace bracketed figures with your latest batch-specific COA data.)

| Compliance-Ready Supply Chain | Every shipment screened for PAH4, heavy metals, pesticide and solvent residues via HPLC and GC-MS prior to release. |
Q1: What is the difference between EGCG 98% and 98% Polyphenols?
A: Polyphenols refer to the total catechin content in green tea, of which EGCG is the most bioactive fraction. Our 98% Polyphenols product typically contains around 50% EGCG, while our dedicated EGCG 98% powder is purified specifically for applications requiring maximum antioxidant potency.
Q2: How is solvent residue verified in your products?
A: Each production batch is tested via GC-MS and HPLC for residual solvents, pesticides and heavy metals, with results documented in a batch-specific Certificate of Analysis (COA) available on request.
Q3: Is your Organic Green Tea Extract suitable for USDA/EU Organic labelled products?
A: Yes. Our Organic Green Tea Extract holds both USDA Organic and EU Organic certification, making it suitable for finished products carrying either organic claim in the US or EU markets.
Q4: What is your minimum order quantity (MOQ)?
A: Our EGCG 98% powder is available from as low as 500g for sampling or small-batch production, significantly lower than the industry-standard MOQ of 500kg–1000kg offered by larger manufacturers.
Q5: Can you provide custom particle size or concentration blends?
A: Yes. Our technical team can provide customised particle size control and concentration blending, with spec sheets and quotations typically issued within 24 hours.
