Based on the staff's reply regarding your sunscreen formula:

Replacing Light Cream Maker with Easy Cream Maker:
- Easy Cream Maker cannot emulsify as much oil as Light Cream Maker.
- Your formula contains 20% SPF Protect Ultra™, which is an oil.
- For stability, using Light Cream Maker (Product ID 141) is recommended. The staff mentioned that Light Cream Maker is currently back in stock.
- Easy Cream Maker (Product ID 533) is suitable for formulas with no more than 10% oil.
Adding Tranexamic Acid and Rice Vitamin and using SiliSolve™:
- You do not need to use SiliSolve™ (Product ID 408) to help mix Tranexamic Acid (Product ID 260) and Rice Vitamin (Product ID 410), even though they are water-soluble.
- Light Cream Maker at 1.5-2.0% is sufficient for emulsification in this formula.
- SiliSolve™ is used for water-in-silicone formulations, which is a different type of emulsion.
Staff's recommendation for Tranexamic Acid:
- If you haven't used Tranexamic Acid (Product ID 260) before, the staff recommends starting with 3% instead of 5% to avoid potential skin irritation.
