Starch-based Pickering emulsions for topical drug delivery: A QbD approach

- A QbD approach was successfully applied to obtain Starch Pickering emulsions.
- Formulation and process parameters allowed modulating droplet size.
- Starch amount highly influenced Pickering emulsions stability.
- Starch Pickering emulsions with suitable rheological and mechanical properties.
- Pickering emulsions were self-preserving and non-irritant for skin application.
