Laundry formulations

Polya.mine-Ba.sed Quaternaries. Another important class of quaternaries are the polyamine-based or polyquats. Generally, polyamine-based quaternaries have been used in the same appHcations as their monomeric counterparts (245). Discussions, including the use of polymeric quaternaries in laundry formulations (246) and in the petroleum industry as damage control agents (247), have been pubHshed. 

In some modern laundry formulations water hardness-promoting ions are bound to aluminosilicates. However, binding of hardness-promoting ions can only take place if these ions are solved in water. Because aluminosilicates or zeoliths are not soluble in water by themselves they are not able to solve insoluble salts of fatty acids already present in incrustations of fibers. For a suf-... 

Commercial Laundry Formulations Phosphated alkali or builder... 

Laundry formulations are the greatest consumer of LAS, being used as the primary surfactant in powder, tablet and liquid formulations providing good degreasing and soil removal properties. Some soap is normally added to the formulation to control the foaming... 

The application of enzymes is now well documented. They are used in organic chemistry - mainly for the production of optically pure compounds - synthesis of detergents and emulsifiers, lipid modification, laundry formulations, food and beverage production etc. [1 - 6]. Due to their high chemo-, regio- and stereoselectivity, activity at ambient temperatures and pH, biocatalysts are often superior to chemical ones and this might explain that a considerable number of industrial bioprocesses have been established in recent years [2,7]. 

The use of builders in liquid laundry formulations has effectively been restricted to citrates and fatty acid soaps (in isotropic compositions sold in the U.S. and Europe). Although liquid laundry products can contain tripolyphosphate, soda ash, NTA, and other common builders found in powder laundry, limitations on solubility (in a surfactant matrix) or regulatory concerns have restricted their utilization. There is a finite number of patents covering zeolite-built HDLDs, but problems...

Antifoam compounds for use in detergents can be found in many types of formulated products including dishwashing detergents and rinse aids, home laundry formulations, home laundry softeners, window cleaners, alkaline metal degreasers, hard-surface cleaners, acid cleaning of metals, bottle-cleaning formulations, and many others. 

What substances have replaced tripolyphosphate in U.S. laundry formulations ... 

Modem laundry formulation incorporates a cocktail of enzymes to hydrolyze protein, starchy, and even greasy soils. Cellulolytic enzymes can also be introduced to minimize color loss to fabric after multiple washings and to reduce cotton dinginess. 

Since soap and detergent action is hindered by hard water, laundry formulations usually include water softeners—called builders—designed to remove hard water ions (especially Ca and Mg ) from the water. A common builder used in North America is sodium carbonate. Suppose that the hard water used to do laundry contains 75 ppm CaC03 and 55 ppm MgC03 (by mass). What mass of Na2C03 is required to remove 90.0% of these ions from 10.0 L of laundry water ... 

Corrosion Inhibitors The basicity and reactivity of ingredients found in laundry formulations lead to attack and corrosion of various metal parts in laundry equipment. To minimize this effect, the sodium silicates are added to the detergent formulation. 

Perfume Perfumes are added to laundry formulations to mask odors of other ingredients and to convey a pleasant odor which may be suggestive of a natural fragrance or of a clean wash. The perfume has essentially nothing to do with effective soil removal but adds to product aesthetics and aids in consumer acceptance of the product.
