Dioctyl carbonate is a colorless to pale yellow transparent liquid with low viscosity, low polarity, and excellent spreading properties, making it a high-performance ester compound. Industrially, dioctyl carbonate is mainly synthesized via transesterification, that is, by reacting dimethyl carbonate or diethyl carbonate with octanol as a raw material in the presence of a catalyst.

Emollients and Skin Feel Modifiers: Dioctyl carbonate possesses excellent skin compatibility and a dry, smooth feel. After application, it spreads and penetrates quickly, forming a breathable protective film on the skin, replacing traditional silicone oil and mineral oil.
Solvents and Carriers: It has extremely high solubility for crystalline organic sunscreens (such as octocrylene), significantly increasing the SPF value of sunscreen products and reducing their greasiness. Simultaneously, it can dissolve active ingredients such as vitamin E, preventing their oxidation and improving product stability.
Dispersants: Dioctyl carbonate effectively disperses physical sunscreens such as titanium dioxide and zinc oxide, as well as pigments, preventing particle aggregation and sedimentation in the formula. This property makes it an ideal additive for foundation, BB cream, and other base makeup products, resulting in a more even and adherent makeup finish.
Makeup Removers: Due to its excellent solubility and good compatibility, dioctyl carbonate is often used as a main ingredient in makeup removers, effectively removing makeup and rinsing easily without leaving any residue on the skin.
