Consumer appeal

Solvents. The most widely used solvent is deionized water primarily because it is cheap and readily available. Other solvents include ethanol, propjdene glycol or butylene glycol, sorbitol, and ethoxylated nonionic surfactants. There is a trend in styling products toward alcohol-free formulas. This may have consumer appeal, but limits the formulator to using water-soluble polymers, and requires additional solvents to solubilize the fragrance and higher levels of preservatives. 

Microemulsions or solubilized or transparent systems are very important ia the marketing of cosmetic products to enhance consumer appeal (32,41). As a rule, large quantities of hydrophilic surfactants are required to effect solubilization. Alternatively, a combination of a solvent and a surfactant can provide a practical solution. In modem clear mouthwash preparations, for example, the flavoring oils are solubilized in part by the solvent (alcohol) and in part by the surfactants. The nature of solubilized systems is not clear. Under normal circumstances, microemulsions are stable and form spontaneously. Formation of a microemulsion requires Httle or no agitation. Microemulsions may become cloudy on beating or cooling, but clarity at intermediate temperatures is restored automatically. 

Some major new factors in modern packaging are the use of graphics for consumer appeal and additional design features for operational convenience. These features have often resulted in higher intrinsic package... 

Astaxanthin (3,3-dihydroxy-p,p-carotene-4,4-dione) is widely distributed in Nature and is the principal pigment in crustaceans and sahnonids. The carotenoid imparts distinctive orange-red coloration to the animals and contributes to consumer appeal in the market place. 

Viscosity measurement or rheology. Viscosity is an important property of many fluids, particularly consumer products. Pancake syrup that does not appear thick or a runny shampoo has little consumer appeal. Viscosity is also an important measurement for liquid polymers. It is a measure of polymer chain length and branching. On the other hand, viscosity does not have the sensitivity to detect small amounts of impurities in pure substance. 

Rheological modifiers (LD, DW, ADW, HC, FC) Improve flow properties of product, enhance consumer appeal, assist manufacturing Rheological behavior Clays Polymers Sodium silicate Sodium sulfate Solvents 0.5-2% 0.5-2% 3-15% 0-5%... 

ODORANT. A substance having a distinctive, sometimes unpleasant odor that is deliberately added to essentially odorless materials to provide warning of their presence. For example, mercaptan derivatives may be added to natural gas for this purpose. In a broad sense, perfumes are odorants that are added to cosmetics, toilet goods, etc, largely for consumer appeal. 

It was ultimately concluded that low-dose gamma irradiation of fresh shrimp reduced melanosis and resulted in a significant extension of their iced-storage life. However, if shrimp were held beyond the onset of melanogenesis, subsequent low-dose irradiation accelerated blackspot formation, which reduced consumer appeal, and therefore was definitely undesirable (3,13). 

Color. Color of citrus fruit at maturity is a major criterion of consumer appeal. In humid, subtropical climates, citrus fruits will reach maturity with a considerable amount of chlorophyll still remaining in the rind. Therefore, considerable interest has been shown in the area of color enhancement through the use of materials applied to mature fruit before harvest. 

Food quality - migrating substances may impart taint or odour to the food and so reduce consumer appeal. 

Wood chips are ordinarily used in amounts ranging between 2g/L and 8g/L for white wines. Higher quantities cause the wines to lose consumer appeal because of the intensity of the wood attributes (P6rez-Coello et al. 2000a). 

World demand for dyes and organic pigments is forecasted to increase 5.1 percent per year to more than US 14 billion in 2004. Gains will result from improvement in the textile industry, which accounts for about 70 percent of the global dye demand [4]. These demand figures include the forecast for plastic application, where more brilliant and striking colors are generating consumer appeal. 

This renewed popularity was most likely at the expense of tallow and palm oil, which lost consumer appeal due to unfavorable publicity highhghting nutritional concerns with saturated fatty acids or cholesterol both of these edible fats and oils crystallize in the beta-prime habit like cottonseed oil. 

Level Control Filler. Plastic bottles can be manufactured clear thus for consumer appeal, they are filled to a level. This means the volume may vary but will appear to be equal due to the visually perceived common level in the containers. Flow is by gravity through a nozzle into a sealed container, whereas air equilibrates via a vent tube (Figure 8). When the rising liquid reaches the air vent port, flow stops. There is no overflow of product as in a pressure or pure vacuum filler. Aeration is at a minimum, perceived fill level is extremely accurate, and the filler is relatively simple and easy to maintain. Size consistency of the blow-molded container is critical to control, because this dictates the amount of product being sold. 

The most important aspect of all pharmaceutical products is that they are consumer products therefore, consumer appeal is of great concern which means for agglomerated specialties that they must have uniform, esthetically pleasing, and reproducible shape and weight. 

The final product has high consumer appeal and increased sales value.
