cleaning process while maximizing the cleaning results.
There are literally hundreds of detergents on
the market, many of which are
similar and many are good. The secret to selecting the proper detergent
specific cleaning job is through an understanding of the different
what purpose each serves.
Parts of Most Detergents:
The following is a list of many of the components
commonly found within most
Surfactants, also known as wetting agents, have
the following functions:
Wetting - Acts to make water "wetter" giving it greater
penetrating power and greater ability to help loosen and remove
soil. Reduces surface tension.
Emulsifying - Helps to solubilize and suspend oil, grease or
other normally water insoluble compounds.
Deflocculation Peptization - Dispersing - Acts to break up and
suspend water insoluble materials such as clay and metal oxides
so they may be more easily removed.
Detergency - This is cleaning ability. It is a combination of
all surfactant functions. There is a large variation of cleaning
ability of detergency. The surfactants in good detergents are
picked because of their superior detergency. This is very important.
Foaming - Surfactants will range from non-foaming to extremely
high foaming. Foam has nothing to do with cleaning ability but
many people believe a cleaner has to foam to be effective.
Biodegradable - All surfactants used in good detergents are
biodegradable. They break down into simpler compounds in sewage
plants, septic tanks or rivers and lakes.
