Hand dishwashing detergents

Liquid detergents based on Pilot Calsoft, Cal suds and Calfoam surfactants produce safe, effective suds with excellent grease-cutting properties for hand dishwashing. Detergents containing Calamide C are especially mild to sensitive skin. 

Of the three main types of surfactants, the anionics are by far the most commercially important class, constituting, in particular, the major surfactant type represented in laundry and hand-dishwashing detergents. Among the anionics, linear sodium alky] benzene sul-fonaie (LAS), linear alkyl sulfates, and linear alkyl ethoxy sulfates are by far the most widely used compounds. (The industry convened voluntarily to linear alkyl chains in the mid-1960s to obtain improved biodegradabilily relative to the branched chain alkylates formerly used.)... 

Recent patents describe the use of low-molecular-weight organic diamines in place of the Ca or Mg divalent ions [91,92], The inventors claim that the diamines in hand dishwashing detergents are most effective when the pH is in the range 8 to 12. The diamines provide the same function as the divalent ions but with additional benefits. The reduction or elimination of the divalent ions leads to improved benefits in dissolution, rinsing, and low-temperature product stability, according to the patents.

HAND DISHWASHING DETERGENTS 3.2.1 Historical Perspective/Evolution... 

An early hand dishwashing detergent is compared to a more recent formulation in Table 3.3. From this comparison one can see that the basic components have not changed much over the years. It is clear that surfactants have been and continue to be the most important ingredients, responsible for cleaning and foaming. 

ASMEs have excellent detergency and are also potential substitutes for LAS. These surfactants have not been used widely in hand dishwashing detergents thus far, presumably because of then-cost and availability. 

In summary, some ways to increase mildness of a hand dishwashing detergent are to... 

The main application of hand dishwashing detergents is to wash dishes by hand. Liquid products can also be used for washing cars, fine laundry, kitchen countertops, and hands. Consumer habits and typical washing procedures vary widely with hand dishwashing. Some of the variables are amount of product used, water temperature, water hardness, use of implements, type of soil, dish surface properties, and time. 

Gentle base for use in hand dishwash detergents, synthetic hand soaps and car washes. High foamer. 

Typical Applications High foaming liquid hand dishwashing detergent, liquid laundry products, car wash.
