Phenyl Trimethicone IOTA 556, also known as phenyl methyl silicone oil, is a premium phenyl-modified polysiloxane widely used in cosmetics for its unique blend of performance-enhancing properties. This colorless, low-viscosity fluid (22.5 cSt at 25°C) combines the benefits of silicones with the optical and emollient advantages of phenyl groups, making it a staple in sunscreens, skincare, and hair care formulations.
Superior Compatibility: Unlike conventional dimethicones, Phenyl Trimethicone IOTA 556 exhibits excellent solubility in alcohols and blends seamlessly with organic oils, resins, and UV filters. This compatibility reduces formulation challenges in sunscreens or makeup products.
Lightweight & Non-Greasy: It forms a breathable, invisible film on skin or hair, delivering silky slip without heaviness. Its refractive index (1.46) enhances product clarity and imparts a natural gloss.
Multifunctional Performance:
Skincare: Reduces tackiness in creams and lotions while improving spreadability. Ideal for sunscreens, where it aids even film formation and water resistance.
Hair Care: Adds shine, softness, and anti-static properties to conditioners, sprays, and serums.
Stability & Safety: With a high flash point (>100°C) and oxidation resistance, it ensures formulation longevity. Compliant with JSCI standards, it is recognized as safe for cosmetic use without concentration limits.
Sun Care: Enhances SPF efficacy by improving water repellency and reducing whitening.
Makeup: Promotes smooth application in foundations and primers.
Hair Styling: Delivers heat protection and gloss in thermal sprays.
Emulsification: Easily emulsified with standard surfactants (e.g., PEG-12 Dimethicone).
Solubility: Dissolves in 95% ethanol (up to 50% at 4°C), enabling clear alcoholic sprays.
Phenyl Trimethicone IOTA 556 bridges the gap between silicone functionality and sensory elegance, making it a go-to for modern cosmetic chemists. Its versatility, safety, and performance underscore its role in next-generation beauty innovations.
