Biocides in Hydraulic Fracturing Fluids: A Critical Review
Biocides are critical components of hydraulic fracturing (“fracking”) fluids used for unconventional shale gas development. Bacteria may cause bioclogging and inhibit gas extraction, produce toxic hydrogen sulfide, and induce corrosion leading to downhole equipment failure. The use of biocides such as glutaraldehyde and quaternary ammonium compounds has spurred a public concern and debate

- What is HPMC aqueous solution?
- Aqueous solution has a surface activity, the formation of the film after drying, heated and cooled, in turn, from the sol to gel reversible transformation. Hydroxypropyl Methyl Cellulose (HPMC) are water soluble polymers derived from cellulose. They are typically used as thickeners, binders, film formers, and water retention agents.
- What is hydroxypropyl methylcellulose (HPMC)?
- Introduction Hydroxypropyl methylcellulose (HPMC; CAS No. 9004-65-3) is used in the food industry as an emulsifier, film former, protective colloid, stabilizer, suspending agent, or thickener. HPMC is approved for food uses by the FDA (21 CFR 172.874) 1 and the EU (EC, 1995); its safety in food use has been affirmed by the JECFA (JECFA, 2004).
- What is HPMC powder?
- 3. Discussion HPMC is an odorless and tasteless, white to slightly off-white, fibrous or granular, free-flowing powder that is a synthetic modification of the natural polymer, cellulose. It is used in the food industry as a multipurpose food ingredient.
- Can HPMC be used as a food additive?
- It is used in the food industry as a multipurpose food ingredient. HPMC is approved by FDA as both a direct and an indirect food additive, and is approved for use as a food additive by the EU. The JECFA has evaluated the food uses of HPMC and established an acceptable daily intake (ADI) of 'not specified' for such uses.
