INCI name for a blend of cyclopentasiloxane and dimethicone is Cyclopentasiloxane (and) Dimethicone Crosspolymer
 
1. Hair Care:
Shampoos and Conditioners: This blend is frequently used in hair care products to provide a smooth, sleek finish without weighing hair down. Cyclopentasiloxane adds a lightweight feel, while Dimethicone provides long-lasting smoothness and frizz control.
Leave-in Conditioners and Serums: The blend helps seal moisture into the hair, adds shine, and detangles the hair. The Cyclopentasiloxane evaporates quickly, leaving the Dimethicone to provide lasting benefits like frizz control and a polished, shiny appearance.
Hair Styling Products (Gels, Mousses, Sprays): The blend can offer enhanced texture and hold while giving the hair a smooth, non-greasy finish.
2. Skin Care:
Moisturizers and Creams: The blend enhances the smooth application of moisturizers, providing a velvety finish without feeling heavy or greasy. It helps in improving the skin's texture by filling in fine lines and giving the skin a soft, hydrated appearance.
Primers: This blend is often found in face primers, where it can fill in pores and create a smooth base for makeup application. Cyclopentasiloxane ensures that the primer applies easily and evenly, while Dimethicone helps in creating a longer-lasting, smooth finish.
Anti-aging and Wrinkle Treatments: The blend can be used in treatments aimed at smoothing out wrinkles, as Dimethicone fills in the skin's surface, making it appear more even and youthful.
3. Makeup Products:
Foundations and Tinted Moisturizers: Dimethicone’s long-lasting properties give makeup formulations more staying power, while Cyclopentasiloxane ensures that the product applies smoothly and dries quickly. The combination provides a natural finish without feeling heavy on the skin.
Powders and Compacts: The blend can help powders glide on smoothly, providing an even, flawless finish and preventing cakiness.
Concealers and Highlighters: It helps products to apply evenly and stay in place throughout the day.
4. Sun Protection (SPF) Products:
Sunscreens and Sunblocks: The blend can enhance the spreadability of sunscreens and help provide a smooth, non-greasy finish. Cyclopentasiloxane provides an initial silky feel, while Dimethicone helps protect and condition the skin.
