Stearyl stearate (Octadecyl stearate), also known as stearyl alcohol stearate or octadecanoic acid octadecyl ester, is an organic compound.
CAS number is 2778-96-3,
Chemical formula C36H72O2,
Molecular weight 536.96.
It appears as a white waxy solid or powder,
Density of 0.9±0.1 g/cm³ (0.857 g/mL at 25°C),
Melting point 62-70°C (another source records 60.85°C),
Boiling point 549.1±18.0°C,
Flash point 297°C.
The substance has 34 rotatable chemical bonds, a hydrophobic parameter XlogP of 17.4, and a topological polar surface area of 26.3. It is commonly used as a biochemical reagent in life science research. Stearyl stearate should be stored in a sealed container at 2-8°C in a cool, dry place. When handling, it is recommended to wear nitrile gloves and an N95 dust mask, and to avoid contact with strong oxidizers. It can be synthesized via esterification of stearic acid and stearyl alcohol using a solid superacid SO₄²⁻/ZrO₂-SiO₂ catalyst, achieving a yield of up to 71.5% under optimal conditions.
