The information below is a structured migration from the supplied catalogue snapshot. It is not a current product specification, COA or SDS. Confirm the actual supplier, grade, batch documents, classification, packing and destination requirements for your enquiry.
Cyclicdimethylpolysiloxane (DMC), often referred to simply as Cyclomethicone, is a blend of cyclic dimethylsiloxane oligomers, primarily D4 (Octamethylcyclotetrasiloxane), D5 (Decamethylcyclopentasiloxane), and D6 (Dodecamethylcyclohexasiloxane). It is a **clear, colorless, odorless, and volatile silicone fluid**. Its unique combination of properties, including excellent spreadability, a non-greasy feel, and rapid evaporation, makes it an indispensable component in a multitude of formulations.

Applications of Cyclicdimethylpolysiloxane
Due to its superior sensory profile and functional attributes, DMC (Cyclicdimethylpolysiloxane) is widely utilized across various sectors:
Personal Care and Cosmetics:
Deodorants and Antiperspirants: Provides a smooth, dry feel and helps deliver active ingredients.
Hair Care: Found in hair sprays, conditioners, and styling products for shine, detangling, and reduced drying time without build-up.
Skin Care: Used in lotions, creams, sunscreens, and makeup removers for its light, non-greasy feel, easy spreadability, and ability to leave skin feeling soft and smooth.
Makeup: Enhances spread and feel in foundations, mascaras, and lip products.
Industrial Applications:
Solvents: Functions as a volatile carrier or diluent for various industrial formulations, including coatings and cleaning products.
Lubricants: Used in specialty lubricants where low viscosity and non-greasy residue are desired.
Textile and Fabric Treatment: Improves the feel and drape of fabrics.
Polishes and Waxes: Aids in spreading and provides a protective, non-oily finish.
Reliable Supply Chain: Our robust production capabilities and efficient logistics ensure a steady and timely supply to meet your demands.
