Gum odina and various parts of the plant Odina wodier are traditionally used in Indian folk medicine. Here an effort was made to investigate the efficacy of gum odina as new pharmaceutical excipients, in particular, as an emulsifying agent. Primary emulsion was prepared using wet gum method taking oil: water: gum (4:2:1) with gum acacia powder as an emulsifying agent. This was used as a standar...

A novel technique for studying the stability of emulsions has been developed. Owing to the fact that emulsion turbidity is a function of particle concentration and size, the stability of emulsions can be determined by measuring the change in turbidity with time. The relationship between turbidity and particle size and concentration is derived for a polydispersed emulsion. The stability of acous...

background microencapsulation is a useful method to prolong a drug release from dosage forms and to reduce its adverse effect (1) among various available methods. the microencapsulation of hydrophilic active ingredients requires the use of a polar dispersing phase such as a mineral oil. acetone/paraffin systems are conventionally used. objectives the current study aimed to investigate two diffe...

J. L. Gao, Y. Zhi, X. F. Ren, Y. H. Liu, College of Material Science and Engineering, Shenyang Ligong University, Shenyang, Liaoning, China. Barium titanate (B aTiO3) nanoparticles were successfully synthesized by using a surfactant-assisted method. The various processing parameters, namely, th e species of surfactant, reaction temperature and micro-emusion concentration had been varied, and th...

There are several techniques available for monitoring emulsions and foams. Early studies usually referred to global measurement of the volumes of the emulsion/foam and of the separated liquid versus time. However, it was soon understood that phase separation is not only a function of time but also of location. With regard to simplicity and fast response, electrical measurements offer a tempting...

In composite materials made of polymer matrices and micro-nano dispersed compartments, the morphology of the dispersed phase can strongly affect several features of the final material, including stability, loading efficiency, and kinetic release of the embedded molecules. Such a polymer matrix composite can be obtained through the consolidation of the continuous polymer phase of a water-in-oil ...
