Adding EGF to Cosmetic Formula: Stability and Handling

Based on the information for Epidermal Growth Factor (EGF, Recombinant), adding 5% is within the recommended usage rate (1-5%, with 3% typically recommended).

However, successfully incorporating EGF into your formula requires careful consideration:

• pH Stability: This specific EGF product is most stable at a pH of 3-5. You must ensure your final formulation's pH is within this range.
• Mixing Method: Add the EGF at the final step of your formulation process, ensuring the temperature is below 40°C (25°C recommended). Blend thoroughly until completely dissolved.
• Storage: The final product containing this EGF should be stored under refrigeration (4°C - 8°C).

Simply swapping water for EGF without adjusting the pH and following the specific mixing and storage instructions may lead to the EGF degrading and losing its effectiveness.
