Abstract: A composition and method for the controlled release of natural plant oils (essential oils) from a wax matrix to repel insects, arachnids, and other arthropods.

Abstract: Methods and compositions for removing contaminants from soil and groundwater by extracting the contaminants and assisting the extraction by provision of an oxidant introduced prior to or simultaneously with a surfactant into the subsurface. Extractable contaminant can be extracted from the subsurface. The amount and/or distribution of contaminant in the subsurface can be characterized. The extracting of contaminant and the introducing of oxidant and surfactant can be coordinated to reduce contaminant to a target amount. A portion of the contaminant can be oxidizable.

Abstract: A method of using a fluid formulation for increasing flow, production, or recovery of oil and gas hydrocarbons from a subterranean formation. Components including a peroxygen, surfactant, alkali metal chelate, and a cosolvent into a hydrocarbon bearing subterranean formation having a blockage or accumulation of material. Oxygen or carbon dioxide gas is generated by decomposition of the peroxygen which creates gas pressure in the formation. The formed gas pressure mobilizes, degrades, removes, releases, realigns or redistributes the material causing the blockage or accumulation physically. The aggregate pH of the components is less than about 10 or a concentration of alkali metal chelate is greater than about 0.2% and less than about 5% by weight of non-water components.
