Effects of fatty acids on polyelectrolyte-surfactant interactions

- Polyelectrolyte-surfactant complexation is affected by the presence of fatty acids.
- Monomeric fatty acid migrates to the polyelectrolyte-surfactant complex.
- Fatty acid aggregates induce polymer adsorption, and prevent complexation.
- In polymer-surfactant emulsions, fatty acids disrupt polymer-induced flocculation.
