Methicone

Silicone

What is Methicone?

Methicone is a lightweight synthetic silicone resin composed of polymethylsilsesquioxane structures, produced through hydrolysis and condensation of methyltrichlorosilane. It appears as a fine, porous powder in cosmetics, particularly in color makeup like foundations and powders, as well as primers and hair sprays. Functionally, it deposits a breathable film that absorbs excess sebum for a matte finish, disperses pigments evenly, and refines texture by scattering light for a soft-focus effect. Its hydrophobic nature repels water while allowing moisture vapor transmission, aiding in long-wear formulations. In hair products, it neutralizes charge buildup for manageability, and its spherical particles enhance slip during application without heaviness.

Skin conditioning agent

Maintains skin softness, smoothness, and flexibility.

Surface modifier

Alters surface properties such as wetting, spread, and feel, helping improve application, coverage, and sensory profile on skin, hair, or pigments.

Antistatic agent

Reduces static electricity and flyaways by improving surface conductivity, enhancing hair manageability and smoothness in conditioners and styling products.

Emollient

Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.

Benefits
