Hydraulic fracturing proppants Hydraulic fracturing proppants A proppant is a solid material, typically sand, treated sand or man-made ceramic materials, designed to keep an induced hydraulic fracture open, during or following a fracturing treatment. It is added to a "fracking fluid" which may vary in composition depending on the type of fracturing used, and can be gel, foam or slickwater–based. In addition, there may be unconventional fracking fluids. Fluids make tradeoffs in such material properties as viscosity, where more viscous fluids can carry more concentrated proppant; the energy or pressure demands to maintain a certain flux pump rate (flow velocity) that will conduct
Guar gum also known to cause small sores or lesions as well as chronic diarrhea (IBS). Manufacturers and suppliers will sometimes substitute guar Gum, xanthan gum and cellulose gum in formulations, without changing product labels. Often, blends of all these ingredients are sold as cellulose gum. If allergic to guar gum, the most common foods to suspect contamination from are frozen dairy/ice treats, soft cheeses (cream cheese, ricotta), salad dressing and baked goods. In July 2007, the European Commission issued a health warning to its member states after high levels of dioxins were detected in a food additive - guar gum -
