Polybutene
Polybutene is a versatile, clear, thick liquid ingredient used in many UK lip products, mascaras and long-wear cosmetics. It gives formulas a smooth, glossy finish and helps products stay put without feeling sticky. Shoppers often see it listed in lip glosses and lipsticks for its cushion-like texture and shine.
How it works in skincare
In cosmetics and skincare, polybutene functions as a film-forming agent, thickener and emollient. It creates a flexible, breathable layer on the lips or skin that locks in moisture while delivering a high-shine, non-greasy finish. Formulators value it for improving the wear time of colour cosmetics and giving lip products that signature cushiony, glossy texture loved by British beauty fans.

Where it comes from
Polybutene is a synthetic polymer produced from the polymerization of butene, a hydrocarbon derived from petroleum refining. While not plant-based, it is highly purified for cosmetic use.
