Advances in colloidal dispersions: A review

Abstract

This paper introduces advanced systems and technique in the field of colloidal dispersions. These systems include the double emulsions, the cubosomes and the solid lipid nanoparticles (SLNs) which are favored by their capacity in the controlled release of ingredients, colorants, drugs, minerals and antioxidant particles. Double emulsions (both water-in-oil-in-water W/OW and oil-in-water-in-oil O/W/O) are considering as ideal materials for microencapsulation while cubosome and SLNs are submicron colloidal carriers. The structure, formulation and applications of those systems will be provided. In the preparation of colloidal dispersions, membrane technology is an interesting alternative method because of low energy consumption and high efficiency. The principle and operation of membrane systems in microemulsification as well as their applications will be summarized and presented.
