2008 - A Review on Applications of Liposomes in Textile Processing

Hossein Barani and Majid Montazer - Journal of Liposome Research, 18:249–262, 2008

Abstract
This review discusses the properties of liposomes and their role in the textile process, including textile preparation and dyeing. Liposomes have a surface activity effect due to a hydrophilic head group and hydrophobic hydrocarbon tail. Its preparations do not
tend to foam, which advantageously distinguishes them from other textile auxiliaries. According to the carrier role of liposomes, they can be used in several textile processes such as textile finishing and dyeing with several types of dyes and fibres. Each application is discussed in this review paper. Several types of dyes are encapsulated by liposomes in the dyeing process and their presence indicates that they have retardant and levelling effects according to their gradual release of dyes. In addition, the presence of liposomes in the textile process can improve the mechanical properties of textile products, resulting in better wash fastness properties and levelling effect and handle properties. The best character of liposomes is a reduction in temperature of process resulting to save energy and they are environment degradable materials.

 
November 2008 - Microencapsulation by solvent evaporation: State of the art for process engineering approaches

Ming Li, , Olivier Rouaud, and Denis Poncelet - International Journal of Pharmaceutics Volume 363, Issues 1-2, 3 November 2008, Pages 26-39

Abstract
Microencapsulation by solvent evaporation technique is widely used in pharmaceutical industries. It facilitates a controlled release of a drug, which has many clinical benefits. Water insoluble polymers are used as encapsulation matrix using this technique. Biodegradable polymer PLGA (poly(lactic-co-glycolic acid)) is frequently used as encapsulation material. Different kinds of drugs have been successfully encapsulation: for example hydrophobic drugs such as cisplatin, lidocaine, naltrexone and progesterone; and hydrophilic drugs such as insulin, proteins, peptide and vaccine. The choice of encapsulation materials and the testing of the release of drug have been intensively investigated. However process-engineering aspects of this technique remain poorly reported. To succeed in the controlled manufacturing of microspheres, it is important to investigate the latter. This article reviews the current state of the art concerning this technique by focusing on the influence of the physical properties of materials and operating conditions on the microspheres obtained. Based on the existing results and authors’ reflection, it gives rise to reasoning and suggested choices of materials and process conditions. A part of this paper is also dedicated to numerical models on the solvent evaporation and the solidification of microspheres. This review reveals also the surprising lack of knowledge on certain aspects, such as the mechanism of formation of pores in the microspheres and the experimental study on the solidification of microspheres.
