Hydrotropic wetting agents enhance the activity of water for earthy materials
by lowering surface tension to promote surface-to-surface contact, to neutralize
the electric double layer, to destroy protective colloids, to neutralize other
charged particles, and to bind water to the materials, thus, significantly reducing
the evaporation rate and, concomitantly, reducing the amount of water that must
be applied and the energy and time used to prepare the material. A wetting agent
suitable for the present invention includes an alkylphenol ethoxylate (APE) and
a polyglycol, such as, for example, glycerin or propylene glycol (when toxicity
is not an issue), and an antifoaming agent, such as for example, a polysiloxane
polymer. These chemicals combined in the concentration ranges of the present invention
produce wetting agent/hydrotropic formulations that maybe used to provide the advantages
of the present invention.
