<p>Improved compositions containing a visible coloring agent, such as a colored pigment or dye, together with a polymer or hydroxylated aliphate alcohol, a surfactant and in some embodiments, a therapeutic agent or biocide, are disclosed. The detectable coloring agent is readily visible under normal white light, and provides a technique for monitoring disturbed and undistrubed areas on a surface. The visible coloring agent of the compositions are further defined as imparting a color to the composition that remains virtually constant upon contact with a contaminant or change in pH of the composition, or of the surface or other environment to which it is exposed. Such is useful in the described methods for cleaning and/or decontaminating a surface, as in the decontamination of equipment and clothing used during hazardous spill response. The compositions are adherent to a variety of different materials, including Teflon®. This makes the preparations particularly useful in the cleaning and decontamination of non-flat and curved surfaces, such as on protective garments. The compositions, in particular embodiments, include a visually detectable coloring agent (such as a colored pigment), a surfactant (such as ethoxylate alcohol), and emulsifier (such as carboxymethyl cellulose), an extender (such as PEG), and a solvent (such as d-limonene). These compositions may also include water or other suitable diluent.</p> |
