All data recorded in the data base have been acquired from plant records. Statistical reductions of data for generation of reports or specific end use are available. Data are currently collected from four operating plants (eight units). Time clocks have been installed on components, to record actual exposure time. Event data are available on a broad variety of safety and commercial grade components including pumps, valves, transformers, diesels, filters, tanks (vessels), and heat exchangers. 

According to the material classes which the graded component combines, e.g. metal/ceramic, polymer/ceramic, metal/metal, ceramic/ceramic, etc.

Surprisingly, microemulsion systems based on technical grade components show the typical sequence of phases observed in many model systems [4]. This demonstrates the universahty and robustness of the principles of microemulsion formation. Although derived from the studies of the phase behavior and the physical properties in microemulsion systems containing highly purified surfactants and hydrocarbons, the found systematics and empirical laws can be apphed to systems based on technical grade components. Hence, the systematic study of the phase behavior is crucial with respect to practical applications. 

First results show clearly that a microemulsion designed especially for the extraction of entrapped toxic compounds in surfaces can also be used as a nanoreactor for the decomposition of these chemicals by oxidizing agents and enzymes. Different degradation methods were already demonstrated to work in model microemulsion systems and can probably be applied also in practically important microemulsion systems. Here, technical grade components suitable for extraction and solubilization have to be used instead of purified surfactants and oils. 

It was already shown that this is possible and the understanding of the behavior of such technical grade components benefits from the great knowledge of the fundamental general principles of the phase behavior in amphiphilic systems obtained in numerous studies. Hence, for the future new decontaminants media as a hard surface cleaner based on microemulsion formulation can be expected for both military decontamination forces and civilian first responders.

Gulik-Krzywidki and Larsson [7], Hernqvist [15], Engstrom [16], and Larsson [17] reported studies that used all food-grade components to formulate w/o microemulsions (L2 phases). They found that a thermodynamically stable oil-continuous phase could be formed with water, triglyceride, and monoglycerides. A representative phase diagram is depicted in Fig. 2.
