Octyldecanol
What is Octyldecanol?
Octyldecanol is a synthetic branched-chain fatty alcohol, typically derived from petrochemical sources or vegetable oils, appearing as a colorless, odorless oily liquid. In cosmetics, it belongs to the emollient and solvent category, commonly found in creams, lotions, serums, and lip products. It functions by forming a thin lubricating film on the skin, which reduces friction for smoother application, fills in minor surface imperfections for a softer feel, and aids in blending oil and water phases in emulsions. As a non-polar solvent, it dissolves hard-to-mix ingredients like fragrances and oils, improving formula stability and texture. Its low viscosity helps create lightweight, fast-absorbing products without greasiness.
