Stability studies of cosmetic emulsions prepared from natural products such as wine, grape seed oil and mastic resin

- Still wine and grapeseed oil can contribute natural components to cosmetic emulsions.
- Low wine concentrations yield rheologically stable O/W emulsions.
- The optimum wine percentage in the aqueous phase was found to be 20% (v/v).
- Mastic resin at 2% (w/v) is optimum for preparing O/W emulsions with grape seed oil.
- Combining wine and mastic resin results in bigger droplets and lower viscosity.
