Mask-Proof BB Cream Ingredients for W/Si Formulas

To make your W/Si BB cream formula mask-proof and transfer-resistant, you can incorporate film-forming ingredients that create a durable layer on the skin.

Key ingredient types commonly used and suitable for W/Si formulas include:

• Silicone Film Formers (Trimethylsiloxysilicate): This group of ingredients forms a silicone film on the skin, helping makeup adhere well and providing water and oil resistance. They are available in various forms depending on the desired wear properties and skin feel:
  • Powder Type: Such as Silicone Film (Powder, Hard Film, Comfort-Wear) or Silicone Film (Powder, Hard Film, Smart-Wear). These disperse well in silicones or Isododecane/Isohexadecane and are suitable for adding varying levels of longevity while maintaining a comfortable feel.
  • Liquid in Cyclopentasiloxane Base: Such as Silicone Film (Comfort-Wear, Hard, Cyclopentasiloxane Base) or Silicone Film (Smart-Wear, Hard, Cyclopentasiloxane Base). These are suitable for foundation, BB/CC cream, or cushion formulas, providing easy application and forming a durable film. Different options offer varying levels of wear and comfort.
  • Liquid in Isododecane Base: Such as Silicone Film (Soft Film, Low Viscosity, Isododecane Base) or Silicone Film (Smart-Wear, Hard, Isododecane Base). While often preferred for fast-drying lip products, some can be adapted for use in other makeup formulas to enhance longevity.
• Fluorosilicone: Such as Trifluoropropyl Dimethicone/Trifluoropropyl Divinyldimethicone Crosspolymer. This silicone contains fluorine, providing excellent water and oil resistance, making makeup long-lasting and preventing color change due to sweat. It is often used to treat pigments or included in formulas requiring high durability.

Tips for Selection:

• Consider the desired level of wear: For very high longevity, you might choose a Very Long-Wear type, but be mindful that it could reduce skin comfort.
• Consider the skin feel: Comfort-Wear or Soft Film types generally provide a more comfortable feel.
• Consider compatibility with your formula: Choose types that dissolve or disperse well in the silicone oil phase of your W/Si formula.

Usage Rate:

Generally, film-forming ingredients can be used at approximately 1-30% for Silicone Film and 1-50% for Fluorosilicone. However, it is recommended to test in your specific formula to find the optimal rate that provides the desired properties without making the product feel heavy or sticky.
