Hard Surface Cleaners. Citric acid and sodium citrate are used in hard surface cleaners as an acid and chelator for dissolving hard water deposits and as a builder to increase the efficacy of the surfactants. 

Trisodium phosphate [7601-54-9] trisodium orthophosphate, Na PO, is an important constituent of hard-surface cleaners including those for ceramic, metal, or painted surfaces. It may be used with soaps, surfactants, or other alkaHes. It precipitates many heavy-metal ions but does not sequester to form soluble chelates. It is thus a precipitant builder and additionally an alkaH. 

Several cleaning formulations for specific uses contain unreacted polyamines. Examples include mixtures of ammonium alkylbenzenesulfonate, solvents, and PIP which give good cleaning and shine performance on mirrors and other hard surfaces without rinsing (305), and a hard-surface cleaner composed of a water-soluble vinyl acetate—vinyl alcohol copolymer, EDA, cyclohexanone [108-94-1] dimethyl sulfoxide [67-68-5] a surfactant, and water (306). TEPA, to which an average of 17 moles of ethylene oxide are added, improves the clay sod removal and sod antiredeposition properties of certain hquid laundry detergents (307). 

A special application of a-sulfo fatty acid esters is for highly concentrated hard surface cleaners which are used after dilution in a pail of water. Normally hydrotropes are needed to increase the solubility of the surfactants in water and assure clear, homogeneous, and storage-stable products. If the LAS, which are typical surfactants in hard surface cleaners, are replaced by ester sulfonates the hydrotrope can be deleted from the formula [62]. 

FOUND IN Conventional laundry detergents, all-purpose cleaners, and hard-surface cleaners Also known as nonyI phenoxy ethoxylate or nonyl phenol ethoxylate. Researchers in England have found that in trace amounts these synthetic surfactants activate estrogen receptors in cells, which in turn alters the activity of certain genes. For example, in experiments they have been found to stimulate the growth of breast cancer cells and feminize male fish.

One of the most important effects of surfactant synergy in liquid hard-surface cleaners is that the overall concentration of active ingredients can be reduced. More importantly, the amount of adjunct materials—builders, solvents, and the like—that must be added are decreased as the surfactant efficiency and effectiveness is increased due to synergy. While this has the effect of increasing...

The major applications of this class of surfactants are shampoos and body washes, and they are often found in conditioning shampoos due to their compatibility with quaternary compounds. The shampoo compositions mostly include from 1 to —8% by weight of amphoterics to help impart aesthetic, physical, or cleansing properties to the composition. Amphoterics also find broad applications in hard surface cleaner formulations and homecare applications, due to their excellent detergency and pH stability. 

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].
