Polydecene
What is Polydecene?
Polydecene is a synthetic hydrocarbon polymer formed by linking decene monomers, creating a clear, colorless liquid. It falls under polyolefins, a group of inert ingredients valued in cosmetics for their stability. Commonly used in moisturizers, serums, sunscreens, and hair products, it acts as an emollient by spreading evenly to create a thin, flexible film on the skin or hair. This barrier helps lock in moisture while allowing skin to breathe, mimicking natural sebum without stickiness. Its low viscosity delivers a silky texture, enhancing product spreadability and reducing the need for heavier oils. Derived through controlled polymerization, it remains non-reactive and resistant to oxidation, ensuring long shelf life in formulations.
