Using Polymethylsilsesquioxane to Improve Pressed Powder Texture

Yes, Polymethylsilsesquioxane can definitely be used in pressed powder formulations to help reduce the roughness of ingredients like Rice Powder.

Polymethylsilsesquioxane is a versatile powder ingredient known for its ability to impart a soft, smooth, and silky feel (often described as "silky & slip") to cosmetic formulations. It also provides a soft-focus effect, helping to diffuse light and visually reduce the appearance of fine lines and wrinkles. Additionally, it has moderate oil absorption properties.

Rice Powder, such as Ricesorb, is excellent for oil absorption and can be a good alternative to Talc. However, as noted in product descriptions, Rice Powder can sometimes have a "dry, unrefined" texture. By incorporating Polymethylsilsesquioxane into your pressed powder formula alongside Rice Powder, you can significantly improve the tactile feel, making the powder smoother, less rough, and more pleasant to apply.

Other ingredients like SiliSilk 1.5Micron are also specifically designed to provide a soft and smooth texture in powder formulations. The use of Polymethylsilsesquioxane for texture modification is also seen in ingredients like Titanium Dioxide 30nm SilkTouch, where it's used as a surface treatment to give pigments a softer feel suitable for makeup powders.

Therefore, adding Polymethylsilsesquioxane is an effective way to enhance the texture and feel of a pressed powder containing Rice Powder, resulting in a smoother, less rough product.
