  • Wetting agent formulations for hydrotropic moisture control of substrates and dispersed phases
    Patent number: 7482385
    Abstract: Hydrotropic formulations for enhancing the moisture control in a wide variety of substrates for a range of applications, such formulations include an alkylphenol ethoxylate (APE) surfactant, a polyglycol, an antifoaming agent, and water.
    Type: Grant

  • Hydrotropic additive to water for dust control
    Patent number: 7482386
    Abstract: Methods for controlling dust which include applying an effective amount of a composition including an alkylphenol ethoxylate (APE) surfactant, a polyglycol, an antifoaming agent, and water, to dust-producing material.

  • Hydrotropic additive for process water used to condition and stabilize soils and other base materials used in construction
    Patent number: 7004687
    Abstract: 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.

  • Inhibited oil field drilling fluid
    Patent number: 4310425
    Abstract: A drilling fluid containing water, a density-increasing agent, and a carbohydrate additive that is subject to deleterious attack in the drilling fluid to which is added a system that will produce in situ in the drilling fluid chlorine dioxide (ClO.sub.2) for alleviating deleterious attack on the carbohydrate additive. The system producing the chlorine dioxide must produce an initial concentration which will reduce the viable organism count and maintain a residual concentration over a protracted interval of time so as to maintain the low bacterial level, maintain the pH of the drilling fluid in the range of 6.0-8.0, and otherwise not interfere with the rheological and beneficial effects of the drilling fluid.
