Product Application
Preparation method: Coconut oil undergoes continuous hydrogenation with a copper‑chromium catalyst to yield C8‑C18 mixed fatty alcohols. The glycerin contained in coconut oil is converted into isopropanol and water during hydrogenation.
The crude mixed fatty alcohol is first subjected to atmospheric distillation to remove water and isopropanol, followed by vacuum distillation for fractionation. Fractions including C8‑C10 alcohol, C12‑C14 alcohol and C16‑C18 alcohol (cetostearyl alcohol) are separated accordingly.
Safety data: MSDS is available for Cetostearyl Alcohol. We also provide information on its upstream and downstream related products.
