Interfacial activity of amino acid-based glycerol ether surfactants and their performance in stabilizing O/W cosmetic emulsions

- Emulsions containing PhGE12 show better stability.
- Increase of surfactant's concentration lead to increased stability.
- PhGE12's emulsions have smaller droplets.
- Interfacial tension has approached its equilibrium value after 1800 s.
- Interfacial rheology seems not to affect emulsion's stability.
