Octadecene
What is Octadecene?
Octadecene is a linear alpha-olefin, an unsaturated hydrocarbon featuring a chain of 18 carbon atoms with a double bond at one end, primarily derived from petroleum refining processes. It falls under the functional category of emollients and solvents in cosmetic formulations, appearing in products like hair conditioners, lotions, and cleansers. Chemically non-polar, it excels at dissolving lipophilic substances, enabling uniform mixing of oils and actives that would otherwise separate. In formulations, it modulates flow properties to prevent excessive thinning or thickening, promoting stability during storage and a desirable glide during use. This supports controlled release of other components and minimizes greasiness, ideal for clear gels and lightweight emulsions across rinse-off and leave-on items.
