Aqueous based replacements for chlorinated solvents meeting standards while minimizing environmental liabilities

The Clean Air Act of 1990 mandates the phaseout of many chlorinated solvents used in numerous cleaning and degreasing applications. Aqueous-based cleaners can be an effective alternative in many applications, however this changeover can require significant laboratory and pilot studies. Prior to the phaseout, little attention was given to the material balances and cleanliness requirements associated with many cleaning applications. Environmental regulations have forced many industries to evaluate material usage rates and waste management options associated with their cleaning applications. Aqueous-based cleaners offer the opportunity to minimize waste generation while achieving the desired cleanliness level. This paper will address the technical issues associated with identifying the types of surfactant and emulsion based organic aqueous cleaners which satisfy common cleaning scenarios. The critical issues typically include cleaning efficiency, management of the washwater, and disposal of cleaning residues. Aqueous cleaners generally offer significant advantages over other alternatives due to the flexibility in designing the most appropriate surfactant and emulsion chemistry.
