Ideal delay formulations

Some of the most important requirements of an ideal delay formulation with reproducible results are ... 

The formulations falling in the zone AA only are selected for actual Service use as these formulations satisfy one of the most important requirements of an ideal delay formulation that is, any minor change in the proportion of ingredients should not affect the burning rate adversely . The delay formulations are categorized in terms of IBR as shown in Table 5.8. 

The clinical development plan to be supported would be idealized, with minimal delays between phases and without substantive changes to the test article (e.g., no changes to manufacturing process or formulation) or the route of administration. 

Controlled or targeted release is the most common apphcation of microcapsules. Microencapsulation is an ideal tool to effect and achieve a desired delay of the active core until the correct stimulus is encountered. Most microcapsules are extraordinarily stable and show a great retardation of the encapsulated substances. Fragrances, aromas, drugs, enzymes, cosmetics and even pharmaceutical formulations (vitamins, drugs) are encapsulated for delivery from textiles at a specific time, rate, or situation. The encapsulated substances can either be released at once...
