Solid-stabilized emulsions, also called Pickering emulsions, are emulsions stabilized by solid particles instead of classic emulsifiers. They are considered either as new dosage forms for topical drug delivery or as new targeting systems in cosmetic and pharmaceutical products. Creative Biolabs is a highly focused research-driven company and have many years of experience and high-end technologies in LDD (lipid-based drug delivery) research, we have successfully developed a series of innovative and liposome development platform to provide fast and convenient services for our worldwide customers. With our unbeatable product portfolio of solid-stabilized emulsions services for drug delivery, we will help you to do a better career in your LDD project.

Background of Solids-stabilized Emulsion

Emulsions are used in many different fields which are now well established and the solid particles of colloidal size may be employed to kinetically stabilize emulsions. Solid-stabilized emulsions are obtained by shearing a mixture of oil, water, and solid colloidal particles. The term ‘Picking emulsion’ has been widely used to describe solid-stabilized emulsion, a kind of emulsion stabilized only by solid particles locating at oil-water interface, and they may advantageously replace conventional emulsions containing organic surfactants. In Pickering emulsions, the stabilizing film in between the droplets comprises very rigid layers that provide a mechanical barrier against coalescence. The solid particles are irreversibly anchored at the oil-water interface and develop strong lateral interactions. Many solid particles can be used in Pickering emulsions including organic (e.g. polymer zein or starch) or inorganic particles (e.g. silica, titanium dioxide and clay particles). Indeed, the continuous phase of an emulsion stabilized by particles having a high degree of hydrophilicity will be the water phase, whereas hydrophobic particles will preferentially stabilize water drops dispersed in an oil phase.
