General Hard-Surface Cleaning Products

Cleaning of floors and woik surfaces in kitchens without machines represents examples of the so-called general hard-surface cleaning tasks. Products designed to assist in this context are invariably aqueous liquids, which may be applied neat or diluted before use. However, formation of excessive amounts of foam produces a concomitant rinsing task. Application of some means of foam control especially during rinsing would appear to be desirable. 

These products tend to be used at ambient or near-amlnent temperatures. Foam control by use of cloud phase antifoams under those omditions would require the use of 

Garrett et al. [108] and later Ashcroft et al. [109] have claimed that a rather novel application of the antifoam synergy found with hydrocarbon-calcium soap mixtures can be applied in this context. Consider then a cleaning liquid where both the hydrocarbon and a sodium soap (or fatty acid) are solubilized in a concentrated aqueous micellar solution of another surfactant. If use of the product involves dilution in hard water, then both the solubilized hydrocarbon and soap will be precipitated as the concentration of micelles decreases and the water hardness increases. It is claimed [108,109] that synergistic foam control is then observed as exemplified by the results shown in Table 8.2. Possibly precipitation of bulk phase hydrocarbon is nucleated on the calcium soap particles so that a hydrocarbon-calcium soap antifoam entity could be formed in situ giving rise to that synergy.

In Indonesia, the Philippines, Malaysia, and Thailand, in addition to the conventional low-concentration dishwashing detergents based on linear or branched alkyl benzene sulfonate, there are creamy products for the general cleaning of hard surfaces. Here also skin compatibility can be further optimized by the use of alkyl polyglycosides.
