Detergents-Liquids—Laundry Liquid Concentrate

Liquid Laundry Detergents (Based on Added Value Surfactant Concentrates)... 

The ARALEX process is relatively simple and involves inexpensive and readily available chemicals. The ARALEX process can also be applied to other actinide waste streams which contain appreciable concentrations of polar organic compounds that interfere with conventional actinide ion exchange and liquid-liquid extraction procedures. One such application is the removal of detergents from laundry or clean-up solutions contaminated with actinides. 

Versatile heavy duty cleaner concentrate specially developed for the formulation of economy laundry detergents, liquid dish-washes, and household/industrial cleaner products. 

The current trend for household laundry is concentrated detergents, both liquids and powders, where packages are smaller, lighter, more convenient, and shipping is less costly. There is a strong need to identify new surfactants that could offer one or more of the following advantages ... 

Historically, these sulfonates have been difficult to produce in good quality and to formulate into laundry powders because of thermal and hydrolytic stability problems. Used basically as an anionic, oleochemically sourced replacement for LAS, FAE sulfonate benefits include good detergency at low concentration, low environmental load, and good supply of high quality material (71). To avoid possible thermal stability problems, these sulfonates have found application in liquid products. They are used in at least one U.S. dishwashing liquid, and the cocoyl derivative, Alpha-Step MC48, is marketed by Stepan Chemical Company. 

The function of hydrotropes in detergency has been discussed as regards their interaction with surfactant colloidal association structures, especially lyotropic liquid crystals. The main activity of the hydrotrope as a part of a liquid detergent is to avoid gelation in both the concentrated package system and under the dilute conditions in the actual laundry process.
