Zeolites are used as detergent builders, adsorbents, and catalysts. In the past decade, we saw the development of a variety of zeoiite membranes, and a number of investigators reported on the preparation of such membranes and their applications to a variety of separation systems. These research activities are motivated by features common to inorganic membranes, such as thermal resistance and resistance to organic solvents, and features unique to zeolite materials, such as molecular sieving, selective adsorption, and catalytic activity.In this article, the discussion will be restricted to zeolite membranes for use in separation and catalysis. First, an overview is presented on recent progress in zeolite membranes, followed by a discussion of our research activities.

Bleach thickening requires the organization of complex fluid matrixes, resulting in different types of observed rheological behaviors. Specific behaviors have been developed to increase the contact time between the bleach and vertical surfaces. Some structures have been also developed to improve the ease of use of the thickened bleach (shear thinning) and to maintain abrasive or detergent builders in suspension. 

The conventional detergent builders [viz., sodium tripolyphosphate (STPP) and tetra sodium pyrophosphate (TSPP)], have been identified as environmentally unsafe as they cause excessive deposition of phosphates in the water bodies and result in eutrophication. This is a process which causes excessive growth of algae in water bodies, which once died and decomposed, can cause growth of organic...

Concerns about the effect of TPP on eutrophication have led many states, cities, and regional governments to ban the use of the compound in syndets. Such bans have caused serious problems for detergent manufacturers, however, because no entirely satisfactory substitute for TPP has yet been found. Two promising candidates are the sodium salt of nitrilotriacetic acid, 3Na, N(CH2C02)3 , or NTA and ethylenediaminetetraacetic acid (EDTA). Both of these compounds act in much the same way as TPP, that is, by sequestering metal ions. Other builders that have been incorporated into syndet formulations include sodium carbonate, synthetic zeolites, borates, and organic polymers known as polycarboxylates. 

Alkaline cleaning solutions contain builders (sodium salts of phosphates, carbonates, silicates, and hydroxides) and surfactants (detergents and soaps). Other additives may include anti-oxidants and stabilizers as well as small amounts of solvents. Acidic cleaning solutions may contain mineral acids (nitric, sulfuric, phosphoric, or hydrochloric), organic... 

Current laundry detergents in powder form contain 8-25% surfactant and 30-80% builders. The builders are mainly inorganic salts, used at fairly high percentages, but a few organic polymeric materials are also used, at low percentages. Sodium polyacrylates have been recommended for use with sodium carbonate as builder. The polyacrylates prevent precipitation of insoluble carbonates (Nagarajan, 1985).
