Science
Mechanism of Action
This molecule utilizes a complex structure featuring a lipophilic C12-15 alkyl chain and a hydrophilic polyethylene glycol head bonded to a phosphate group. It stabilizes emulsions through a combination of steric hindrance and electrostatic repulsion, effectively lowering interfacial tension to keep oil and water phases unified.
