Question

Two o/w emulsions are prepared with an anionic surfactant and two different polymers. The formulator assesses surfactant-polymer chemical interaction through  _________ , geometric features through _________. From ___________measurements, he figured that polymer A-surfactant interaction is stronger than polymer B-surfactant interaction.

Explanation / Answer

Two o/w emulsions are prepared with an anionic surfactant and two different polymers. The formulator assesses surfactant-polymer chemical interaction through interfacial tension, geometric features through contact angle. From Static Light Scattering measurements, he figured that polymer A-surfactant interaction is stronger than polymer B-surfactant interaction.

Emulsions are commonly classified into two types: (1) oil-in-water (O/W) emulsions, in which oil droplets are dispersed in an aqueous medium; (2) water-in-oil (W/O) emulsions, in which water droplets are dispersed in an oil medium.
