Ingredient Profile and Specifications

Within the realm of personal care, Phenyl Methyl Cosmetic Silicone Oil IOTA556 (Phenyl Trimethicone, CAS# 73559-47-4) stands out as a noteworthy ingredient. Classified as a polymethylphenylsiloxane, it appears as a clear, colorless liquid with stable physical and chemical characteristics. Its viscosity at 25℃ is 22.5, with a specific gravity of 0.980 and a refractive index of 1.46. The flash point exceeds 100℃, and the acid value is maintained below 0.1 mg KOH/g. These precise specifications are crucial for ensuring product consistency and reliability.

Sensory Benefits and Solubility

The primary value of IOTA556 lies in its ability to deliver a pleasant sensory experience to the end-user. It is easy to emulsify and shows good compatibility with a wide range of cosmetic ingredients, ensuring a uniform and refined texture. Upon application, it spreads easily, leaving a smooth, non-oily finish and effectively resisting tackiness, which allows the skin to feel fresh and breathable. Its antioxidant properties also help extend the product's shelf life. Notably, its excellent solubility in alcohols is a significant advantage; it dissolves readily in 95% ethanol at room temperature and maintains a 50% solubility even at 4℃, opening up new possibilities for formulation design.

Broad Range of Applications

As a multifunctional additive, IOTA556 performs well in both skincare and hair care products. In lotions, creams, and sprays, it provides water-resistant properties and improves spreadability, making the product feel smoother during application. In shaving products, it acts as a lubricant, minimizing skin irritation. In hair styling and care products like hair gels and conditioning sprays, IOTA556 not only aids in styling but also infuses hair with shine and softness. It effectively counteracts the stickiness of other components, allowing hairstyles to remain naturally dynamic and touchable even with long-lasting hold.
