Waree Tiyaboonchai and Garnpimol C. Ritthidej Development of indomethacin sustained release microcapsules using chitosan-carboxymethylcellulose complex coacervation Songklanakarin J. Sci. Technol., 2003, 25(2) : 245-254 Indomethacin sustained release microcapsules were prepared by complex coacervation of chitosan (CS) and carboxymethylcellulose (CMC) and then were hardened with glutaraldehyde (...

Microencapsulating sunflower oil, lemon and orange oil flavour was investigated using complex coacervation of whey protein/gum arabic (WP/GA). At pH 3.0-4.5, WP and GA formed electrostatic complexes that could be successfully used for microencapsulation purposes. The formation of a smooth biopolymer shell around the oil droplets was achieved at a specific pH (close to 4.0) and the payload of oi...

China) Abstract: The microencapsulated display device is the main choice for electrophoretic display. The application of environment friendly dispersion medium is very critical for the commercialization of this technology. The electrophoretic microcapsules using Isopar L, which is non-toxic, low aromatic concentration and volatility, as dispersion medium were prepared by complex coacervation be...

The spontaneous assembly of chemically encoded, molecularly crowded, water-rich micro-droplets into periodic defect-free two-dimensional arrays is achieved in aqueous media by a combination of an acoustic standing wave pressure field and in situ complex coacervation. Acoustically mediated coalescence of primary droplets generates single-droplet per node micro-arrays that exhibit variable surfac...

Curcumin (CU) loaded solid lipid nanoparticles (SLNs) of fatty acids (FA) were prepared with a coacervation technique based on FA precipitation from their sodium salt micelles in the presence of polymeric non-ionic surfactants. Myristic, palmitic, stearic, and behenic acids, and different polymers with various molecular weights and hydrolysis grades were employed as lipid matrixes and stabilise...

Microencapsulation of substances applied on textiles is a relatively new method with many advantages applied in many different fi elds. There are many effective approaches to microencapsulation for decreasing release of fragrances and active substances such as essential oils and cosmetic ingredients using cyclodextrins, yeast cells, chitosans, melamine-formaldehyde or poly(L-lactide) as wall ma...
