Formula Review Summary

Here is a summary of the staff's feedback on your two serum formulations:

Formula 1

• Dipotassium Glycyrrhizate and Glycyrrhetinic Acid: These ingredients have similar functions. The staff recommends choosing only one, with Glycyrrhetinic Acid being more effective.
• Phospholipid: The concentration used (5%) is too high. The staff recommends reducing it to 3%.
• Emulsifier/Cream Maker: The formula currently lacks an ingredient to emulsify the water and oil phases.
• Oil Phase (Squalane): The 40% Squalane content is likely too high and will be difficult to emulsify. The staff recommends keeping the total oil phase below 30%.
• Production Service: If you submit this formula for production as a secret formula, the R&D staff can help adjust the oil ratio and select a suitable cream maker.

Formula 2

• Satin Cream Maker™ and Calcium Pantothenate: Calcium Pantothenate is an electrolyte, which might make emulsification with Satin Cream Maker™ slightly difficult. The staff suggests increasing the Satin Cream Maker™ concentration to 1.5-2.0% to potentially resolve this.
• Allantoin: The concentration used (0.5%) is slightly above the recommended limit based on the water content (57% water allows for a maximum of 0.285% Allantoin).
• Other Ingredients: The other ingredients in this formula are fine.

I hope this summary is helpful!
