Octyldodecyl Stearoyl Stearate

What is Octyldodecyl Stearoyl Stearate?

Octyldodecyl Stearoyl Stearate is a high-molecular-weight ester produced by esterifying octyldodecanol, a branched fatty alcohol derived from natural oils, with stearoyl stearic acid. This creates a waxy, non-polar substance ideal for oil-based cosmetics. Commonly found in lipsticks, foundations, creams, and lotions, it functions by melting at skin temperature to deliver a silky, non-greasy slip. It lubricates skin surfaces, reducing friction for easier application, while thickening formulations to prevent separation and improve stability. Its large size prevents deep penetration, focusing benefits on the outer skin layer for a protective, smoothing barrier that supports hydration without greasiness.
