BENEFITS & USES
Key Benefits
• Provides excellent slip and spreadability
• Delivers a lightweight, non-greasy skin feel
• Improves product glide and aesthetics
• Evaporates after application, leaving no residue
• Enhances hair smoothness and shine
Typical Applications
• Face creams, lotions, and serums
• Sunscreens and makeup products
• Hair serums, conditioners, and styling products
• Antiperspirants and deodorants
• Silicone-based emulsions and anhydrous systems
HOW IT WORKS
Cyclopentasiloxane is a low-viscosity, volatile silicone that spreads rapidly on skin and hair, reducing surface friction during application. After spreading,
it gradually evaporates, helping deposit other conditioning agents evenly while avoiding a heavy or oily after-feel. This mechanism improves sensory performance, product elegance, and ease of application in both skin and hair care formulations.
