Because of these unique properties, xanthan gum has utility in a wide range of applications. In the petroleum area, xanthan gum is used to thicken oil-well drilling fluids and to provide viscous aqueous solutions for enhanced oil recovery. In the industrial area, xanthan gum finds utility in thickening textile printing pastes, acid and alkaline cleaners, slurry explosive formulations, and in a wide range of other industrial applications.

The noncrosslinked ASE polymers are of interest due to their good electrolyte tolerance and their tendency to thicken formulations containing high levels of alkaline salts and builders. Thus, these types of polymer are often preferred in industrial and institutional cleaners. 

One of the main problems with these types of cleaners has been the mist produced by the trigger sprayer. The situation is similar to the irritation described above for general bathroom cleaners. Although this mode of delivery contributes much to the convenience of the product, it also makes the product very unpleasant to use. The respirable particles produced with their high alkalinity and bleach can be very irritating to the consumer. One way to combat this is to thicken the product, and there is literature to show that this can be done with polymers [341] or with surfactants [342-346], or a combination of both [347], The important aspects to balance are reducing the mist produced by the product while still achieving a consumer-acceptable spray pattern. If the product becomes very thick, the spray pattern often collapses to a narrow stream. For some uses, this kind of pinpoint application may be preferable, but for other consumers, a broader spray pattern is expected. 

Commercial amphoterics such as dihydroxyethy-lalkyl glycinates (Figure 15.27) are considered excellent thickeners for strongly alkaline oven cleaners, as well as for acid toilet bowl cleaners. 

Importantly, stability and performance at acidic and alkaline pH extremes are a signature characteristic of these surfactants. Thus, for example, commercial amphoterics such as dihydroxyethyl alkyl glycinate are considered to be excellent thickeners for strongly alkaline oven as well as acid toilet bowl cleaners. Amine oxides enjoy similar properties. Resistance to both acids and bases make them suitable for use in products such as hypochlorite and phosphoric acid hard surface cleaners, hair dyes, corrosion inhibitors, and printing inks [4]. 

Likewise, thickened aqueous hypochlorite compositions rely on these surfactants to accomplish the same purpose at alkaline pH levels of 11 or higher [47]. Desired viscosity for such formulas may range from 150 to 3000 cP. This would not only permit easy dispensing, but provides good coating action necessary for cleaning toilet bowls, bathroom tiles, and shower walls [48]. Effective viscosity control is also necessary to suspend abrasives found in scouring cleansers. Finally, the choice of the particular amphoteric surfactant is an important factor in the preparation of low solvent hard surface cleaners [49-50].
