Loose Powder Base Powder Recommendation

Based on your goal of creating a loose powder that is "white, radiant, and does not darken during the day (after contact with skin oil)", let's look at the two base powder options you are considering:

• Silk Talc Powder (Silane Coated): This powder is treated with Silane, providing a very soft, smooth texture and excellent waterproof properties. The Silane coating helps prevent the powder from darkening when it comes into contact with sweat or oil, and Talc itself offers good whiteness.
• Synthetic Fluorphlogopite (Methicone Coated): This synthetic mica is known for its superior whiteness, brightness, and sparkling effect compared to natural mica. The Methicone coating gives it a soft, smooth feel, improves adhesion, and provides good waterproofness and oil absorption. Its ability to reflect light contributes significantly to a radiant and bright appearance.

Considering your desired "radiant" or "ผ่องเด้ง" effect, Synthetic Fluorphlogopite (6 Micron, Methicone Coated) would be the more suitable base powder. While both coated powders offer good resistance to darkening from oil, Synthetic Fluorphlogopite's inherent brightness, sparkle, and light-reflecting properties are specifically beneficial for achieving a radiant finish.

The other ingredients you've included will also support your goal:

• SelectSorb™ (High Oil Absorption PMMA): This is excellent for absorbing excess skin oil, directly addressing the issue of the powder darkening throughout the day.
• AminoSilk™ (Lauroyl lysine): Enhances the softness, smoothness, and waterproofness of the powder, improving feel and wear time.
• MakeGlow™ Powder (Bismuth Oxychloride): Adds a lustrous texture and a "dewy-glow" effect, further boosting radiance.
• Titanium Dioxide 200nm EasyDisperse™: Provides essential whiteness and coverage.
• Beige Iron Oxides EasyMix™: Provides the necessary color pigment.
• Magnesium Stearate: Helps bind the powders together and improves adhesion to the skin.

In summary, for a loose powder that is white, radiant, and resistant to darkening from oil, using Synthetic Fluorphlogopite (6 Micron, Methicone Coated) as your base powder, combined with the other ingredients you've selected, is recommended.
