1-Eicosanol Usage And Synthesis

Chemical Properties

white fluffy crystalline powder

Uses

arachidyl alcohol is an emollient and a thickener. It is often incorporated into cosmetics to prevent moisture loss and improve skin smoothness.

Uses

1-Eicosanol has been used:

  • in gradient HPLC-charged aerosol detection method for the detection of different lipids
  • as internal standard during determination of policosanol′s high molecular weight alcohols (policosanol′s fatty alcohols) in fish oil by GC

Definition

ChEBI: A fatty alcohol consisting of a hydroxy function at C-1 of an unbranched saturated chain of 20 carbon atoms.

General Description

The polymorphism of 1-eicosanol has been studied by X-ray powder diffraction, differential scanning calorimetry (DSC), Raman scattering and IR spectroscopy.

Flammability and Explosibility

Not classified

Purification Methods

Crystallise the C20 alcohol from *benzene or *benzene/pet ether. [Beilstein 1 IV 1900.]
