Dimethyl Silicone Oil

Dimethyl silicone oil (also known as polydimethylsiloxane, PDMS) is a popular ingredient in cosmetics and hair care for its smoothing, protective properties, and SHENGRUIXIANG’s Dimethyl Silicone Oil category provides high-purity options. Our silicone oil is highly refined, offering a smooth, non-greasy texture that enhances product feel—ideal for moisturizers, foundations, hair conditioners, and styling products. It acts as an emollient (softening skin and hair), occlusive (locking in moisture), and lubricant (reducing friction between hair strands or skin). Unlike low-quality silicone oils that may leave residue, our high-purity version is easily absorbed and rinsed out (when needed), making it suitable for both leave-in and rinse-off products. We offer different viscosities (from low-viscosity oils for serums to high-viscosity oils for creams), allowing clients to customize product texture: low-viscosity oils add light hydration, while high-viscosity oils provide richer moisture. Our silicone oil is compatible with most cosmetic ingredients and tested for safety (non-irritating, non-comedogenic) and stability (resistant to heat and oxidation). For hair care, it helps reduce frizz, improve shine, and protect against heat damage from styling tools. For cosmetics, it creates a smooth base for foundations, reducing cakeiness and improving wear time. Our technical team provides guidance on dosage—too much can make products feel heavy, while too little reduces smoothing effects. SHENGRUIXIANG’s Dimethyl Silicone Oil helps brands create products with a luxurious feel and effective performance.
