These include: • Gels and pastes (three agents: oil, water and solid). Lesser products for pharmacy use include: • Parenteral nutrition products. • Vitaminised nutraceutical suspensions and vitamin supplements. 3). , 1995a) and better product stability. 2 Phenomenological representation of the basic forms of ‘emulsions’ and ‘emulsified products’ used in pharmacy. The schematic shows a two-dimensional representation (not to scale) of three-dimensional entities. 2. The emulsion, liposome and micelle represent the most widely used nanoparticles in contemporary pharmacy (Sarker, 2005a, 2006a).

Manufacturers of emulsion products examine and consider the following both for evaluation of the risk of product change and to formulate an idea of product longevity: • temperature; • humidity; • lighting intensity cycling. As well as their effects on degeneration. ); • visual appearance; CH02 WHAT IS AN EMULSION? g. 1). g. g. g. biosurfactant and mucilage generation. One factor that clearly does drive coalescence is compaction and compression of droplets in the creamed layer of a standing emulsion.

2008; Sarker, 2012a). , 2007). Targeting the brain and nervous system with nanoparticle vehicles is made more difficult by the inherent impermeability of the structure, the transmembrane transportation and the tight junctions of this tissue. , 2009). Tight junction sizes ranging from 3 to 15 nm have been reported; molecules and particles of this size (occasionally subject to in situ modification) are limited to molecular masses of around 250 kDa. This greatly favours the use of microemulsions and micelles rather than 100 nm vehicles for targeting.
