Question

Can Silicone Film (Comfort-Wear, Hard, Cyclopentasiloxane Base) with INCI: Cyclopentasiloxane, Trimethylsiloxysilicate be used in mascara formulations?

Answer

Yes, Silicone Film (Comfort-Wear, Hard, Cyclopentasiloxane Base) can be used in mascara formulas.

This ingredient is a film former (Trimethylsiloxysilicate) dissolved in a volatile silicone (Cyclopentasiloxane). It is highly effective in mascara for the following reasons:

Benefits in Mascara:

  • Waterproofing & Smudge-proofing: It creates a durable film that helps the mascara resist water, sweat, and sebum, preventing smudging throughout the day.
  • Long-lasting Wear: It helps the pigment adhere to the lashes for an extended period.
  • Comfort: The "Comfort-Wear" version is designed to provide a film that is not too brittle, making it comfortable for daily wear on the lashes.

Usage Recommendations:

  • Formula Type: It is best suited for anhydrous (waterless) mascaras or Water-in-Silicone (W/Si) emulsions.
  • Usage Rate: 5-30%, depending on the desired level of durability and film thickness.
  • Mixing: Mix it into the silicone or oil phase of your formula. It can withstand heat during the mixing process.

Alternative Options:

If you require different levels of performance, you may consider:

  • Silicone Film (Very Long-Wear, Hard, Cyclopentasiloxane Base): For maximum durability and extreme waterproof performance.
  • Silicone Film (Smart-Wear, Hard, Cyclopentasiloxane Base): For a balance between long-lasting wear and a lightweight, comfortable feel.

In summary, it is an excellent choice for creating long-wear or waterproof mascara.
