Formulation ingredients

Liquid Dosage Forms. Simple aqueous solutions, symps, elixirs, and tinctures are prepared by dissolution of solutes in the appropriate solvent systems. Adjunct formulation ingredients include certified dyes, flavors, sweeteners, and antimicrobial preservatives. These solutions are filtered under pressure, often using selected filtering aid materials. The products are stored in large tanks, ready for filling into containers. QuaUty control analysis is then performed. 

The dry blend can also be extmded and the extmdate chipped to produce pellets of PVC compound which can then be subsequendy reprocessed to produce the final product. This has the benefit of ease of storage of raw materials since all the formulation ingredients are contained bound in the gelled compound. Many producers of flexible PVC only purchase PVC compound, and many companies exist solely to produce PVC compound rather than a tme end product such as sheet, flooring, or pipe. 

Plasticizer Efficiency. This is a measure of the concentration of plasticizer required to impart a specified softness to PVC. Such a softness of material may be measured as a British Standard Softness (BSS) or a Shore hardness (Pig. 1). Por a given acid constituent of plasticizer ester, ie, phthalate, adipate, etc, plasticizer efficiency decreases as the carbon number of the alcohol chain increases, eg, for phthalate esters efficiency decreases in the order DBP > DIHP > DOP > DINP > DIDP > DTDP. An additional six parts per hundred in PVC of DIDP rather than DOP is required to give a hardness of Shore 80 when ah. other formulation ingredients remain constant. The consequence of this depends on the overall formulation and product costs. In addition to size of the carbon number of the alcohol chain, the amount of branching is also significant the more linear isomers are of greater efficiency. 

Plastisol Viscosity and Viscosity Stability. After the primary contribution of the resin type in terms of its particle size and particle size distribution, for a given PVC resin, plastisol viscosity has a secondary dependence on plasticizer viscosity. The lower molecular weight and more linear esters have the lowest viscosity and hence show the lowest plastisol viscosity, ie, plastisol viscosity for a common set of other formulation ingredients...

Advances in quality control requirements for rubber compounds have demanded that special care is exercised in the weighing of the various fillers and critical small volume powders necessary for the formulation. Ingredient weighing systems are available which can be tailored to the specific requirements of individual factories. Additional components can include conveyors, bagging units and pneumatic conveyance systems.

The preservative must be completely compatible with all other formulative ingredients and does not interfere with them, nor do they interfere with the effectiveness of the preservative agent. 

These studies point towards the need to optimize moisture content of the wet mass and extrudate by careful selection of formulation ingredients and type of extruder. A basket or gear/roll extruder is preferred for a very dense and moist wet mass, as it generates little shear and rise in temperature, while an axial or radial screw extruder which increases granule density and hardness is desirable for a wet mass which is less cohesive with poor binding. 

In order to achieve the goals of pyrotechnic delay formulation, ingredients are chosen and formulated in an elegant way. The ingredients of a pyrotechnic delay formulation are (i) fuel (carbonaceous materials or inorganic substances) (ii) oxidizer (iii) binder and (iv) retardant, if required. 

Prospective, multisite, uncontrolled clinical studies were conducted to study the effectiveness of the formulations and the acceptability of the polym ethane delivery system. The formulation was imbibed into 2.5-in. hydrophilic polyurethane foam discs (LMI, St. Charles, MI). Each disc contained 2.4 g of the formulation. The method of application was developed in tests that limited the active ingredient to the same amount or less than the monograph specifications for the formulation ingredients. Fourteen volunteers were given boxes containing 42 individually wrapped foam pads impregnated with the fonnulation and were asked to complete the questionnaire weekly. 

Further, the use of aqueous additive systems eliminates dust and compaction problems associated with the handling of powder form additives. Finally, the use of aqueous additive systems provides flexibility for mixing the additive with the resin. The additive can be mixed and dried with the resin still in moist, wet-cake form. It can be blended with other formulation ingredients, or pumped into an extruder or kneader during the compounding step. This flexibility can, in turn, provide still lower-cost processes and improved uniformity of mixing. 

Manufacturers of specialty chemical inhibitor formulation ingredients (the polymer manufacturers mainly) are still not able to confirm, with any degree of certainty, the minimum amount of product necessary to achieve any particular level of inhibition performance under various real-time, cooling system operating conditions. (The levels of active inhibitors proposed in most manufacturers technical literature tend therefore to be high, and when linked to the prices charged may make for uncompetitively priced formulations.)... 

Preformulation should include rigorous studies to determine the number of polymorphs that exist, relative degree of stability of the various polymorphs, solubilities, method of preparation of each form, effect of micronization and tableting, and interaction with formulation ingredients.
