Laundry Detergents Anionic Nonionic

At the same time, surfactants like alkylbenzene sulfonates remain the most widely used basis for laundry detergents. Anionics remain the main products for making detergent compositions. Some of the application aspects of relatively new types of anionics (a-olefin sulfonates, sulfocarboxylic acids, alkyl phosphates etc.), whose commercial manufacture began in the 60-ties - 70-ties of the 20 century, are described by Stache [95]. The application of conventional types of nonionics like ethoxylated alcohols or alkyl phenols is presented in [13 -14], Alkyl polyglycosides were widely used in the last 5-8 years [96]. However, the main tendency in the development of new generation detergents is the use of surfactant mixtures in their optimum composition [97, 98].

Nonionic surfactants are also used in substantial amounts in laundry detergents and in automatic dishwashing detergents, both applications reflecting in particular their generally lower sudsing characteristics than the anionics. Commercially important examples uf the nonionics include the alkyl ethoxylates, the ethoxylated alkyl phenols, the fatly acid ethanol amides, and complex polymers of ethylene oxide, propylene oxide, and alcohols. 

This section briefly describes the anionic and nonionic surfactants commonly used in commercial HDLD formulations. Cationic surfactants, although used on a large scale, are found predominantly in rinse-added fabric softener products. LAS, alcohol ethoxylates, and alkyl ether sulfates are three of the most widely used surfactants in liquid laundry detergents [44], Recently, various external considerations, such as environmental pressures, have prompted manufacturers to change their surfactant mix to include newer natural-based surfactants [45-47], including alkyl polyglucosides (Henkel) [48],...

The major component of a laundry detergent is surfactant. Surfactants, alone and in combination with other ingredients, work to remove soils from the surface of the cloth through emulsification, roll-up, and electrostatic forces. A variety of different surfactants have been used in laundry detergents, and they can be classified as anionic, nonionic, and cationic. 

Dimethicone copolyol has been used to help make stable emulsions and dispersions of silicone fluid in detergent applications. In addition, the fact that the dimethicone copolyol is nonionic makes it compatible with both cationic and anionic systems. Consequently, one would expect to encounter the use of these materials to couple silicone fluid into fabric softeners and laundry detergent systems. 

Applications. Linear alkylbenzene sulfonate is a very cost-effective surfactant which is extensively used in a broad variety of detergents for household, fabric care, institutional, and industrial products. lii laundry products (powders and liquids), LAS is generally the workhorse surfactant of choice, usually used in combination with other anionic or nonionic surfactants. LAS is also an appropriate anionic surfactant for light-duty and delicate powder laundry detergents. 

One of the unique performance attribute of amine ethoxylates is their ability to remove grass stains. Amine ethoxylates show better grass stain removal than most anionic and nonionic surfactants used in laundry detergents (Table 3). 

Compared to the commonly used anionic and nonionic surfactants, amphoter-ics/betaines are generally mild, with lower skin and eye irritation. Amphoter-ics/betaines can therefore be used in laundry products where mildness is an important criteria, like laundry detergents for baby clothing and for sensitive skin people. Fine-fabric wash formulas can also benefit from addition of amphoteric/betaine surfactants. Laundry bar formulations can incorporate amphoteric/betaine surfactants in order to improve the mildness on hands.

Nonionics account for roughly 40% of worldwide surfactant use. Nonionics are generally more tolerant than anionics of water hardness, which makes the requirements for builders in laundry detergents less demanding. They tend to be more effective than other surfactants for removal of oily soil from synthetic fabrics. Most nonionics are considered low-foaming products, have good cold water solubility, and have a low critical micelle concentration, making them effective at low concentration. Their compatibility with cationic fabric softeners makes them preferable to anionics in certain formulations. They are more common in industrial applications than are anionics. 

In contrast with soaps, virtually all die synthetic anionic and nonionic surfactants do not form readily visible insolubles in the presence of the Ca++ and Mg-+ ions present in many water supplies—the familiar scum, curd, and lime soap of the laundry soap era. This property, in combination with the discovery that the detergency performance of many synthetic surfactants could be greatly augmented by the addition of certain phosphate chelating agents, led to the "detergent revolution" in the laundry-product field. Sec also Surfactants. 

The ARALEX process can also be used to extract detergents from aqueous solutions containing actinides for example, contaminated laundry solutions. Detergents from all three classes (anionics such as alkyl sulfates and alkyl benzene sulfonates cationics such as N-benzyl-N-alkyl dimethyl ammonium chloride and nonionics such as polyoxyethylenated alkyl phenols) are...
