Colloidal Complexation in Emulsion Stability Systems
Summary
Colloidal complexation underpins the stabilisation of emulsions by the adsorption and assembly of colloidal particles and macromolecules at the oil–water interface. In such systems, amphiphilic biopolymers or inorganic nanoparticles bind through non-covalent forces—hydrogen bonding, hydrophobic interactions and electrostatic attraction—to form robust interfacial layers. These layers reduce interfacial tension, inhibit droplet coalescence and slow Ostwald ripening, thus extending emulsion lifetime. Advances in understanding colloidal interactions at both molecular and mesoscopic scales have revealed how multi-component complexes, such as protein–polyphenol assemblies or polysaccharide–tannin networks, can be engineered to tailor droplet size, rheology and responsiveness to environmental stimuli. This has propelled applications from food and pharmaceuticals to agrochemicals and cosmetics, where precise control over droplet architecture translates into improved texture, bioactive delivery and shelf stability. Recent insights into the kinetics of adsorption, the role of droplet surface coverage and the dynamics of interfacial viscoelasticity have refined design rules for next-generation emulsion stabilisers based on renewable materials, meeting consumer demand for clean-label formulations and addressing environmental concerns.

Colloidal Complexation in Emulsion Stability Systems publication trend
The graph below shows the total number of articles in colloidal complexation in emulsion stability systems across all publications each year (not limited to Nature Index journals).
Technical terms
Colloidal complexation: The assembly of particles or macromolecules at an interface via non-covalent interactions, forming stabilising layers around droplets.
Pickering emulsion: An emulsion stabilised by solid colloidal particles adsorbed at the oil–water interface rather than by molecular surfactants.
Interfacial tension: The force per unit length at the interface between two immiscible phases, reduced by adsorbed stabilisers.
Ostwald ripening: The process by which smaller droplets dissolve and redeposit onto larger ones, driven by differences in Laplace pressure.
Zeta potential: The electrical potential at the shear plane surrounding a particle, indicative of colloidal stability in suspension.
Viscoelasticity: The combined viscous and elastic response exhibited by an interfacial layer or bulk material under deformation.
