Final product formulation

In addition to the studies listed in Figure 4.5, stability characteristics of the protein with regard to e.g. temperature, pH and incubation with various potential excipients are studied. Such information is required in order to identify a suitable final product formulation, and to give an early indication of the likely useful shelf-life of the product (Chapter 6).

Thus, it can be seen that several of the fragrance modifications created for the line extensions have successfully completed the standard stability tests and the final selection can be made based on additional criteria, such as cost and hedonics. These fragrances can then be submitted to Business Scents Ltd with confidence that they are likely to be stable for at least a year, as long as the bases used are not radically altered. However, it remains the client s and their contract manufacturer s responsibility to carry out their own stability testing in the final product formulations to ensure their consumer safety and acceptability. 

The addition of such a substance prior to extraction is effected only when the added substance is a desirable component of the final product formulation where the extract will be used. Consequently, for liquid-phase extraction, this practice is more useful in industrial process apphcations such as, for example, the use of alcohol for the production of extracts to be used in the confection of liqueurs. In gas-phase extractions, however, this technique is very useful in enhancing the volatihsation of analytes. This has apphcations in the analytical... 

Surfactants constitute some of the most important (in terms of function, not quantity) ingredients in cosmetic and toiletry products, foods, coatings, pharmaceuticals, and many other systems of wide economic and technological importance. In many, if not most, of those applications, polymeric materials, either natural or synthetic, are present in the final product formulations or are present in the targets for their use. Other surfactant applications, especially in the medical and biological fields, also potentially involve the interaction of polymers (including proteins, nucleosides, etc.) with surfactant system. 

No matter what delivery form is chosen, the components of the carrier should be evaluated for their compatibility with the final product formulation in which they will be incorporated. Likewise is tiue for their safety profiles. Moreover, components that are already approved globally should be considered, especially if the product is to be used worldwide. It is possible that certain components may be more suitable for particular applications, but higher concentrations of certain excipients may not be desirable. Having chosen a desired delivery system, all enzyme formulations should be evaluated for their shelf stability as stand-alone products. Stability evaluations should encompass activity and phase stability after several freeze/thaw cycles, at elevated temperatures and in humid environments, and long-term stability at ambient and cold temperatures. 

Utility systems are unique and in part defined as traditional utility systems and in part as processing equipment. Part of the system is supplying noncontact utilities and part of the system is supplying products that contact the final product or intermediates. One example of these dual systems is the water systems. There are the traditional cooUng waters for jackets and heat exchangers, but also there are varied clean water systems that supply water that are used in processing intermediates or final products, as well as, being used as part of the final product formulation. 

Topical issues on the advantages and limitations of TG-MS with respect to other evolved gas analysis techniques have recently been summarised by Raemaekers and Bart a.l0] in a review on TG-MS thermal degradation of polymers. The advantageous applications of the technique in polymer science can be extended from qualitative thermal degradation analyses to thermooxidation, structural characterisation and chemical analyses, kinetics, solid-state reaction mechanisms, chemical reactivity and curing, quantitative analyses, and finally product formulation and development.
