In modern cosmetic formulations, performance alone is no longer enough—sensory feel and visual appearance play an equally important role. High refractive index phenyl silicone fluids, such as IOTA 21555, are designed to enhance both, delivering a superior look and a refined touch without adding heaviness.
IOTA 21555 is based on Trimethyl Pentaphenyl Trisiloxane, a phenyl-modified silicone fluid.
Its unique molecular structure gives it a high refractive index, allowing it to reflect light more efficiently.
This results in a bright, clear, and elegant gloss on skin or hair—more “radiant” than greasy, making it ideal for premium cosmetic formulations.
● Enhanced Gloss and Radiance
Improves the visual appeal of formulations, giving a luminous and high-end finish.
● Lightweight, Non-Greasy Feel
Provides a smooth, silky touch while reducing the heavy or sticky feel of other ingredients.
● Excellent Spreadability
Applies easily and forms a uniform film on skin or hair.
● Good Compatibility
Works well with a wide range of cosmetic oils and silicone-based systems.
● Easy to Formulate
Can be emulsified using standard processes and common emulsifiers.
● Strong Stability
Offers good oxidative stability for long-lasting performance.
High refractive index phenyl silicone fluids like IOTA 21555 are not just functional ingredients—they are formulation enhancers that elevate both appearance and sensory experience.
As the demand for lightweight, glossy, and premium-feel products continues to grow, this type of material is becoming an essential choice for advanced cosmetic formulations.
