Detergency Fundamental processes

Washing and cleansing are processes that involve many interfacial effects, which is why a fundamental description of detergency has to be very complex. If we cluster the different processes involved, we can distinguish the following main steps in the cleaning process ... 

One of the most common examples of an electrophilic aromatic substitution is Friedel-Crafts alkylation [40], These days, many important industrial processes are based on this type of Friedel-Crafts-chemistry [41]. The manufacture of high-octane gasoline, ethylbenzene, synthetic rubber, plastics and detergent alkylates are examples. Moreover, the Friedel-Crafts alkylation is among the most fundamental and convenient processes for C—C bond formation on arenes, especially for the synthesis of fine chemicals and agrochemicals containing functionalized arenes and heteroarenes. 

A fundamental part of protein extraction is solubilization. Without some form of fractionation or enrichment processing step, several proteins tend to be underrepresented in datasets. Even with specialized membrane protein selective detergents, some form of bias may occur, as the abundance of these... 

The number of electron equivalents required for complete reduction of this enzyme in the fuUy oxidized state is one of the most fundamental properties of the enzyme to be carefully determined. However, the determination for cytochrome c oxidase is not easy in contrast to those for small hydrophilic metalloproteins, since complete anaerobiosis for an aqueous solution of a detergent-solubUized large membrane protein is extremely difficult to attain. Furthermore, the stability of the enzyme is also very critical for the time-consuming process of complete removal of O2 from the enzyme. Considering these factors, few reports are reliable. 

The rationale for specific goals of this proposal is that the first step in new catalytic processes can be the availability of novel catalytic materials. Our initial focus has been to synthesize and characterize a variety of OMS and OL materials and scout out reactions that can be catalyzed by such systems. Catalytic oxidations with OMS and OL materials provide outstanding selectivity to terminal olefins and alcohols from alkanes. We have chosen to pursue these specific oxidations due to their importance in chemical synthesis and detergent applications,and to explore the fundamental reasons that such systems are highly active and selective. At the same time we have tried to limit our proposed synthetic efforts to a few new target OMS systems based on past experience. 

The manufacture of compressed dosage forms (Figure 19.19) for pharmaceutical products has been known for over 200 years and it is this process technology, which has been anployed to make by far the vast majority of detergent products in unit dose form. The fundamental aspects of compaction are common to all compacted materials and the tabletting machines nsed by different industries are also basically similar. The standard steps in nniaxial die compaction are as follows ... 

Personal Care. The addition of PEO provides a silky feel to solid and liquid products. This imique lubricious property has been successfully exploited in formulation of razor strips (202,203) and in shampoos, detergents, and other personal care applications. The combination of water solubility and the ability to produce films and other devices by thermoplastic processing enables the use of the PEO in flushable articles (204-207). PEO has also been used as an antimisting agent in personal care and cleaning formulations (208) and has been shown to enhance the deposition of active ingredients to the hair and skin, as well as to act as a foam enhancer (209). Fundamental investigations have examined the interaction of PEO and surfactants in aqueous solutions (210-213).
