Clarification on the Concentration Percentage of EGT-Max™ (Ergothioneine) Powder

Asked by: vichai_chan On: October 26, 2025 Product Type: Cosmetics

Question

I am confused about the concentration of EGT-Max™ (Ergothioneine). Does the specification stating 0.3% pure EGT mean that 1 gram of EGT-Max™ contains 0.3% pure EGT, or does 5 grams of EGT-Max™ contain 0.3% pure EGT?

Please clarify how the 0.3% pure EGT concentration relates to the purchased quantity (e.g., 1g or 5g) of the EGT-Max™ raw material.

Answer

Clarification on EGT-Max™ (Ergothioneine) Concentration

Thank you for your question. The confusion regarding the concentration of EGT-Max™ is understandable.

EGT-Max™ (Ergothioneine) is a raw material supplied in powder form. The concentration of pure Ergothioneine is fixed at 0.3% within the EGT-Max™ powder itself.

This means the percentage refers to the composition of the raw material, not the package size:

  • 0.3% pure Ergothioneine is present in the EGT-Max™ powder.
  • This concentration is constant, regardless of whether you purchase 1 gram, 5 grams, or any other quantity of the EGT-Max™ powder.

Example: If you use 1 gram of EGT-Max™ powder in your formulation, you are incorporating 3 milligrams (0.3% of 1g) of pure Ergothioneine.
