Description

C24-28 Alkyl Dimethicone is a high-molecular-weight organomodified silicone fluid, where long-chain C24-28 alkyl groups are grafted onto a polydimethylsiloxane (PDMS) backbone. This unique structure provides exceptional compatibility with organic oils and waxes, delivering superior lubricity, water repellency, and skin-feel enhancement. It is a critical ingredient for formulators in the personal care and cosmetic industries seeking to create premium, long-lasting products with a non-greasy, velvety finish.

Application

• Premium Skin Care Formulations: Acts as a high-performance emollient and skin protectant in anti-aging creams, lotions, and serums, providing a smooth, luxurious feel.
• Color Cosmetics: Enhances the spreadability, wear-time, and water resistance of foundations, lipsticks, and sunscreens while improving pigment dispersion.
• Hair Care Products: Used in conditioners, serums, and styling aids to impart exceptional shine, reduce frizz, and provide heat protection without buildup.
• Decorative & Industrial Coatings: Serves as a flow and leveling agent, as well as a mar-resistant additive, in specialty coatings and inks.
• Plastic & Rubber Processing: Functions as an internal lubricant and mold release agent, improving processing efficiency and surface quality of finished parts.
• Textile & Fiber Treatment: Imparts durable softness, water repellency, and lubricity to synthetic and natural fibers.
