Green Tea Extract EGCG 98% (Epigallocatechin Gallate)

[Frequently Asked Questions]

Q1: Is your EGCG 98% powder truly white in color?

A: Yes. Unlike lower-grade green tea extracts (50%-80%) which appear brown or yellowish, our EGCG 98% is a highly refined crystalline powder that is white to off-white. This indicates the removal of chlorophyll, caffeine, and other polyphenolic impurities, making it ideal for color-sensitive formulations like serums or clear beverages.

Q2: Does this product comply with EU Regulation 2022/2340?

A: Absolutely. We provide a batch-specific HPLC analysis that quantifies individual catechins (EGCG, EGC, ECG, EC). This allows you to accurately calculate the daily dose to ensure it stays below the 800mg EGCG limit required for the European market. We also provide guidance on the mandatory hepatotoxicity warnings for your labels.

Q3: What is the caffeine content in your 98% EGCG?

A: Our EGCG 98% is practically decaffeinated, with a caffeine content of less than 0.1%. It is suitable for "jitter-free" metabolic supplements and evening-use skincare products where caffeine is undesired.

Q4: What is your MOQ ?

A: Most industrial manufacturers require 10–25kg. However, at Blueeyes Bio, we understand that R&D teams and pilot-scale formulators need to verify purity and stability first. We offer a Flexible MOQ to your entry risk and allow for independent lab verification before you commit to bulk orders.

Q5: What documentation is provided with each shipment?

A: Every order is accompanied by a professional documentation pack, including:

• Certificate of Analysis (COA) with HPLC chromatograms.

• Material Safety Data Sheet (MSDS).

• Heavy Metal & Pesticide Residue Report.

• Microbial Panel (TPC, Yeast/Mould, E. coli, Salmonella).

Q6: How should I stabilize EGCG in my formulation?

A: EGCG is sensitive to high pH and light. We recommend formulating at a pH below 4.5 or adding antioxidants like Ascorbic Acid (Vitamin C) at a 1:1 ratio to prevent oxidation. For specific technical guidance, our UK-based support team can provide matrix-specific consultation after your purchase.

Q7: Where is the product shipped from, and what is the lead time?

A: The product is manufactured in our GMP-certified facilities in China (the source of the raw tea leaves) and managed by our UK Limited Company. Shipping typically takes 8–15 business days via air freight to most global destinations (UK, EU, USA, Middle East).
