Silico® ULV Ultra-Low Viscosity HMDSO

Silico® ULV Ultra-Low Viscosity is a volatile silicone blend specifically designed for high-performance personal care applications. With an ultra-low viscosity of just 0.65–1 cSt, it offers rapid evaporation, exceptional spreadability, and delivers a richer, longer-lasting sensory experience.

Introduction

Silico® ULV Ultra-Low Viscosity is a cutting-edge volatile silicone blend engineered for advanced personal care formulations. With an exceptionally low viscosity of 0.65–1 cSt, this fluid is designed to spread effortlessly across the skin, leaving behind a smooth, silky finish without any greasy residue.

Its fast evaporation rate makes it an ideal alternative to traditional cyclomethicone or other volatile carriers, especially in formulations where a lightweight skin feel and quick dry-down are essential. Beyond its elegant aesthetics, Silico® ULV enhances product performance by improving the uniformity of application, helping active ingredients distribute more evenly across the skin or hair.
