Ingredient Profile and Formulation Advantages
Phenyl Methyl Cosmetic Grade Silicone Fluid IOTA556, also referred to as Polymethylphenylsiloxane, is a functional silicone fluid that has garnered significant attention in the cosmetic raw materials market. Its INCI name is Phenyl Trimethicone, and it is registered under CAS# 73559-47-4. The core appeal of this silicone lies in its outstanding formulation compatibility. It is easy to emulsify and blends harmoniously with a wide range of cosmetic ingredients. Its inherent antioxidant properties also help extend the shelf life of cosmetic products. Sensorily, IOTA556 distinguishes itself with its non-greasy and anti-tack characteristics, delivering a silky, breathable feel to lotions and creams. Additionally, its high refractive index of 1.46 makes it an excellent choice for enhancing product shine and improving hair softness.
Versatile Applications and Solubility Characteristics
The multifunctional nature of IOTA556 allows it to act as a versatile workhorse in cosmetic formulations. As a water-resistant additive and viscosity modifier, it is widely incorporated into skincare lotions, creams, sprays, and shaving emulsions. It effectively improves the spreadability of products, reduces stickiness, and enhances overall user comfort. In hair care lines, whether in hair sprays or conditioning mists, the addition of IOTA556 significantly boosts hair shine and softness, giving hair a healthier and more lustrous appearance. Moreover, its solubility in alcohols is particularly impressive. It dissolves effortlessly in 95% ethanol at room temperature and can maintain a solubility ratio of up to 50% by weight even at 4℃, opening up new possibilities for formulating alcohol-based cosmetic products.
Product Specifications and Regulatory Compliance
As a mature cosmetic ingredient, IOTA556 demonstrates consistent stability across all its physicochemical indicators. It is a colorless liquid with a viscosity of 22.5 at 25℃, a specific gravity of 0.980, a flash point above 100℃, and a low acid value of 0.1 mg KOH/g, ensuring mildness and safety. From a regulatory standpoint, IOTA556 is listed as Methylphenylpolysiloxane (code 104207) in the JSCI inventory and falls under category 1-11 in the CLS inventory, with no restrictions, facilitating compliant product launches. To preserve product quality, IOTA556 should be stored in a sealed container at room temperature or below 25℃, with a shelf life of 30 months from the production date. Before use, it is essential to thoroughly review the product safety information sheet to ensure standardized handling and protect personnel health and safety.
