Cyclic silicone oil (such as D5) possesses a unique cyclic molecular structure, endowing it with low viscosity and easy volatility. Upon application to the skin, it evaporates rapidly without leaving any greasy residue, delivering an ultimate refreshing and silky touch. Thanks to this advantage, it is widely used as a carrier solvent for sunscreens, foundations, and other makeup products, serving as an indispensable lightweight base in modern high-end cosmetic formulations.
