Undecane
What is Undecane?
Undecane is a linear aliphatic hydrocarbon with 11 carbon atoms, belonging to the alkane family. It is typically obtained through petroleum refining or synthetic processes from various feedstocks. In cosmetic formulations, it serves as a solvent and is commonly incorporated into anhydrous products like hairsprays, deodorants, and dry shampoos. Its key function involves dissolving non-polar ingredients such as fragrances, oils, and polymers, while its low viscosity and high volatility enable smooth application and rapid evaporation. This results in a silky, matte texture without residue buildup, enhancing user experience in sprayable or quick-dry products. Undecane's inert properties make it compatible with a wide range of cosmetic components, supporting stable emulsions and improved sensory attributes.
