A Lightweight High-Refractive Phenyl Silicone for Clear and Refined Radiance

Product Overview

IOTA 56A is a low-viscosity phenyl-modified silicone fluid designed to deliver high refractive performance with a lightweight sensory profile. By incorporating phenyl groups into a trimethylsiloxane-based structure, it provides enhanced optical clarity while maintaining excellent spreadability.

With a refractive index of approximately 1.498, IOTA 56A offers a clear, bright, and refined shine, making it especially suitable for color cosmetics, sun care, and lightweight skincare formulations.
