Dimethicone 350: A Mid-Viscosity Silicone with Superior Spreadability

Dimethicone 350 is a non-volatile, medium-viscosity silicone that enhances the texture and feel of cosmetic, skincare, and haircare formulations. It forms a protective, breathable barrier on the skin and hair, offering excellent spreadability, moisture retention, and a non-greasy, silky finish. Whether you’re formulating lightweight lotions or luxurious hair serums, Dimethicone 350 delivers shine, smoothness, and enhanced performance without the heavy feeling of thicker oils.

Key Features & Benefits

• Enhanced Spreadability: Dimethicone  provides a rich, silky application, reducing tackiness in lotions and improving the overall sensory experience.
• Moisture Barrier: It forms an occlusive barrier, locking in moisture and protecting skin and hair from environmental elements.
• Haircare Benefits: Improves wet and dry combing, increases shine, reduces static, and works as a humidity resistor or anti-frizz agent.
• Non-Greasy Finish: Despite its viscosity, Dimethicone offers a velvety, matte finish, making it suitable for skincare and cosmetic products without leaving a greasy residue.
• Versatile in Formulations: Suitable for body lotions, hair serums, makeup primers, conditioners, and sunscreens. It enhances product performance by increasing water resistance and providing lasting smoothness.
