Influence of the inner droplet fraction on the release rate profiles from multiple W/O/W emulsions

- We prepared W/O/W emulsions containing magnesium ions in the inner aqueous droplets.
- Magnesium delivery was due to diffusion phenomena.
- The rate of magnesium release was lowered by increasing the inner droplet fraction.
- Such evolution could reflect the increasing tortuosity of the diffusion pathways.
