Can I Store My Lipid In An Aqueous Solution?

We do not recommend storing lipids in aqueous solutions. Note, the shelf life of lipids in aqueous solutions depends on a number of factors including temperature, pH, medium, etc. Lipids stored in a buffer at pH 7.4 at 4°C are typically stable for 5-7 days. Beyond that time, the lipids slowly degrade generating the lyso lipid and free fatty acid via hydrolysis.
