white fluffy crystalline powder
The Uses of 1-Eicosanol
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
The Uses of 1-Eicosanol
arachidyl alcohol is an emollient and a thickener. It is often incorporated into cosmetics to prevent moisture loss and improve skin smoothness.
What are the applications of Application
1-Eicosanol is a non-ionic surfactant
Definition
