Title: Where Formulation Stability Meets Sensory Elegance

In the evolution of personal care products, the synergy between robust performance and exquisite sensory attributes is non-negotiable. IOTA 99366 Silicone Emulsifier (INCI: Lauryl PEG-9 Polydimethylsiloxyethyl Dimethicone) is a scientifically engineered lipophilic copolymer designed to master this balance. It serves as a foundational ingredient for formulators aiming to create next-generation skincare, color cosmetics, and sun care products with unparalleled texture and stability.

This emulsifier distinguishes itself through its versatile and robust emulsifying capability. It proficiently stabilizes both water-in-silicone and conventional water-in-oil emulsions. Its true versatility shines in emulsifying a wide array of oils, from volatile silicones to rich esters and vegetable oils, granting exceptional formulation freedom. Coupled with superior powder dispersing power, it ensures flawless application in makeup and sunscreen formulations.

Processing efficiency is significantly enhanced. Its powerful emulsifying action often allows for lower processing temperatures and simplified procedures. In all-liquid systems, effective emulsification can be achieved with vigorous agitation at room temperature, streamlining pilot-scale and production-scale manufacturing.

Ultimately, the technology culminates in a signature skin feel. Emulsions stabilized with IOTA 99366 deliver a characteristically luxurious, silky-smooth finish that is remarkably non-greasy and non-tacky. This transforms the application into a sensory delight, directly enhancing consumer satisfaction and product perceived value.

Application Guidance:
For optimal results, pre-mix the emulsifier thoroughly with the oil phase. Gradually add the aqueous phase under high-shear agitation. Incorporating electrolytes (e.g., 0.5-2% NaCl) into the water phase is recommended to maximize long-term shelf stability. The addition of polyols (e.g., glycerin) can improve freeze-thaw stability, while adjusting the aqueous phase ratio allows for precise texture customization, from light lotions to rich creams.
