Polymethylsilsesquioxane Particle Size, Coverage, Soft-Focus, and Comparison with Silk Mica Powder
Question
Could you please explain how the particle size of Polymethylsilsesquioxane affects its performance, specifically regarding coverage and blurring effects? I'm interested in knowing if Polymethylsilsesquioxane 2microns provides the best coverage compared to larger sizes (4.5, 7, 10 microns). Additionally, can Polymethylsilsesquioxane be used as a base in formulations instead of or in combination with Silk Mica Powder (e.g., 20 Micron, Methicone Coated) to achieve a smoother texture and better blurring/soft-focus effect?
Answer
Polymethylsilsesquioxane Micron Sizes and Coverage
Regarding Polymethylsilsesquioxane, your understanding is correct. The particle size significantly impacts its performance in a formulation.
- Smaller particle sizes provide a more detailed texture and offer better coverage, making them effective for blurring imperfections and filling fine lines and wrinkles.
- Larger particle sizes tend to feel rougher on the skin but offer more natural transparency and less coverage.
Among the sizes available (2, 4.5, 7, and 10 microns), the Polymethylsilsesquioxane 2microns has the smallest particle size. This means it will indeed provide the best coverage and help to hide wrinkles and imperfections most effectively compared to the larger micron sizes.
All micron sizes of Polymethylsilsesquioxane contribute to a soft-focus effect by refracting light, which helps to visually blur the appearance of wrinkles and create a smoother look.
Polymethylsilsesquioxane vs. Silk Mica Powder as a Base
Polymethylsilsesquioxane is an excellent choice for creating a smooth, silky feel and providing a soft-focus effect in cosmetic formulations. It is specifically designed to help blur the appearance of lines and wrinkles through light diffusion and can give a very smooth, almost powdery slip to products.
Silk Mica Powder (like the 20 Micron, Methicone Coated version) also provides softness, lightness, and natural concealment. However, Polymethylsilsesquioxane, particularly the smaller particle sizes, is often preferred when the primary goal is significant soft-focus, wrinkle blurring, and a very smooth, line-filling texture.
Using Polymethylsilsesquioxane as a base instead of or in combination with Silk Mica Powder can certainly help achieve a smoother, more refined skin feel and enhanced light diffusion for a blurring effect.
