Detergent is a very broad term; it includes various kinds of industrial detergents and commercial detergents. Commercial detergent is the most common type of detergent for consumers. Besides the strength of detergency and cleaning efficiency, the property of low foaming has become an important aspect in developing both commercial and industrial detergents.

In industrial scale cleaning, having too much foam means more water and electricity are needed to remove the foam and thus increase in cost. Furthermore, operation speed, efficiency and service life of certain facilities and equipment might decline due to long period of time soaking in foam and detergents. A balance between detergency and foam can be achieved by adapting low foaming nonionic surfactant in detergent formulation. Low foaming nonionic surfactants have great surface activity, detergency, wettability, dispersancy and lubricity. At low temperatures low foaming nonionic surfactants still remain excellent fluidity and dispersancy, as well as resistant to hard water, salt, acid and alkali. In addition, low foaming nonionic surfactants can be used in conjunction with other nonionic surfactants, anionic surfactants and cationic surfactants.
Managers of land and aquatic systems have something in common. That is, they must manage vegetation at some point during the year. Probably it is weedy plants in crops, undesirable plants in lakes or ponds, invasive plants on rangelands, or unwanted vegetation in forests. For all of these instances, control of plants is a common risk.
Control of plants is most generally achieved by using herbicides with a nonionic surfactant. Spraying herbicides to regulate unwanted vegetation is considered to be cost and time reliable. Nevertheless, treatment needs to be taken in picking the herbicide which has to have the ability to manage the undesirable plant while being fairly safe to non-targets and the atmosphere. Additionally, it is common for the herbicide spray to consist of an adjuvant that will boost the performance of the herbicide.
Anionic surfactants-- have a negative charge and in liquid services they create anions. Anionic surfactants enhance foaming and various other spreading properties of a liquid and are generally used in hair shampoo. If anionic surfactants are used with herbicides, the spray mix can create huge amounts of foam that can negatively impact spray distribution and the control of plants.
Ampholytic surfactants-- have both favorable and negative charges and in aqueous remedies, they are capable of producing anions and cations, depending on the pH of the option. Amphoteric surfactants are used rarely. When used, the amphoteric surfactant has to match the properties of the herbicide formulation.
Nonionic surfactants-- produce little or no ionization (no electric charge) in water. Nonionic surfactants do not have a charge-in option and are the most frequently used surfactants with herbicides.
Why are nonionic surfactants favored for usage with herbicides?
&#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#;-&#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#;&#;&#;&#; are the generally used and popular surfactants for application with many pesticides, including herbicides, growth regulators, defoliants, fungicides, and pesticides.
&#;Properties of nonionic surfactants
&#;It Is composed of alcohol and fats.
&#;Remain steady in cold water.
&#;Have no electrical charge
&#;Are compatible with numerous herbicides
&#;Benefits of using nonionic surfactants with herbicides
Do not harm plants when used effectively. Nonetheless, the application rate is important because when they are used at too high a price, injury to wanted plants (non-targets) may occur. Decrease surface tension of the spray service and increase coverage and wetting ability of the applied spray. Less expensive than other kinds of surfactants.

There was a time when the word &#;surfactant&#; was foreign to me. As a young boy growing up on Long Island, I remember watching my mother frantically trying to clean up some unknown food or drink spill from our carpet before company came. She&#;d scrub and scrub, actually spreading the spill instead of cleaning it.
And, of course, with no carpet spot remover in the house, she would be forced to try whatever was handy, such as laundry detergent, dish soap, maybe even some alkaline degreaser from my dad&#;s workroom.
&#;Shouldn&#;t you use carpet cleaner on that?&#; I&#;d ask.
&#;It&#;s just soap,&#; she would reply. &#;It&#;s all the same.&#;
Today, as a cleaning product formulator, I get to play with all sorts of different chemicals. I spend my weekdays measuring and mixing, adding a pinch of this and a jigger of that. I guess you could say I&#;m one part chef, one part kid with a chemistry set.But there is one thing that I have learned over my years of studying chemistry and working as a formulator: It is most definitely not all just soap.
Perhaps the most misunderstood and confusing components of cleaning chemicals are the actual detergents, or surfactants.
View the Infographic &#;Anionic, Nonionic, Cationic, and Amphoteric Surfactants
Surfactants (short for surface-active agents) are molecules that contain a hydrophilic, or &#;water-loving&#; end, and a hydrophobic, or &#;water-fearing&#; end. The electrical charge on the water-loving end of the molecule distinguishes between the different types of surfactants.
Surfactants come in four different types: Anionic, nonionic, cationic and amphoteric.Once you understand the differences between these different surfactant types, as well as how to classify them by their names, choosing the right cleaning products should be a snap.
Probably the most commonly used surfactants in carpet cleaning chemistry are anionic surfactants.Anionic surfactants possess a negative charge on their hydrophilic end. This charge helps the surfactant molecules to interact with both the carpet fibers and soil particles, lifting and suspending soils in &#;bubble-like&#; arrangements called micelles.
Anionic surfactants possess other benefits that make them ideal for certain carpet applications. Generally, they make a lot of foam when agitated. Also, they tend to be flaky or powdery when dry, not sticky like other surfactants.Anionic surfactants, therefore, are the most common type of surfactant found in low moisture carpet cleaners, like traditional shampoos and encapsulation products.However, these detergents tend to not be as good at emulsifying oily soils as some other detergent types.
When reading the ingredients list on your cleaning products, you can identify anionic surfactants as those that have the following in their names:
Sodium
Ammonium
Magnesium
Sulfate
Sulfonate
Gluconate (For example, sodium laurel sarcosinate, magnesium laurel sulfate, and sodium gluconate.)

Nonionic surfactants are also found in many cleaning products, including carpet products. Nonionics have no charge on their hydrophilic end, which helps make them superior oily soil emulsifiers.
Some nonionics are high foamers (like anionics), while others do not generate much foam. Because of their lower foam profile and strong emulsifying potential, these surfactants are the preferred choice when formulating extraction cleaners and pre sprays. However, unlike anionic surfactants, nonionics are thick liquids or syrups that are sticky or &#;gooey&#; to the touch. When left in the carpet, nonionic surfactants are the primary contributors to rapid resoiling.
Even with that being the case, their importance as cleaners outweighs this negative, and the cleaner or technician must take care to remove as much of the detergent residue as possible from the carpet in order to get the cleaning benefits of nonionics without their negatives.
Nonionic surfactants include:
Ethoxylates
Alkoxylates
Cocamide
Cationic surfactants are less common in cleaners, and almost always absent from carpet products. Cationics have positively charged ends, which makes them ideal in antistatic formulas like fabric softeners and automobile &#;cheater waxes.&#;Also, cationic surfactants have antimicrobial characteristics, and they are found in hard-surface disinfectants and cleaners. However, cationic surfactants have been shown to damage the mill-applied protectants on carpet, and are therefore strictly verboten in carpet products.
Formulas containing cationic surfactants cannot be mixed with those containing oppositely charged anionic surfactants. The molecules would interact with each other, producing a gooey mess that drops out of solution.When reading the ingredients list, look for the words &#;chloride&#; or &#;bromide&#; (as in alkylbenzene ammonium chloride) to identify cationics.
Probably the least talked about surfactants are the amphoterics. These unique molecules possess both a positive and a negative charge on their hydrophilic end, giving them a net charge of zero.
Amphoteric surfactants have little utility on their own, but work extremely well in enhancing the cleaning effect of both anionic and nonionic surfactants. They can serve as &#;coupling agents,&#; which hold the surfactants, solvents and inorganic salt components of a formula together.
Amphoterics are usually named in some way to indicate that they are amphoterics, as in amphoterge. Other examples of amphoterics are betaines and amine oxides.
With all these different types of surfactants, and with a seemingly infinite list of each type of surfactant, it is a wonder that formulators are able to choose the right detergent for the right application. Experienced formulators have gotten their hands dirty working with many different types of detergents in an effort to make just the right blend of cleaning agents. Any formulator worth his salt will be quick to tell you that not all surfactants are created equal, and that some cleaners are better than others, given the situation.
Surfactants are a primary component of cleaning detergents. The word surfactant means surface active agent. As the name implies, surfactants stir up activity on the surface you are cleaning to help trap dirt and remove it from the surface.
Surfactants have a hydrophobic (water-hating) tail and a hydrophilic (water-loving) head. The hydrophobic tail of each surfactant surrounds soils. The hydrophilic head is surrounded by water.
When there are a sufficient amount of surfactant molecules present in a solution they combine together to form structures called micelles. As the micelle forms, the surfactant heads position themselves so they are exposed to water, while the tails are grouped together in the center of the structure protected from water.
The micelles work as a unit to remove soils. The hydrophobic tails are attracted to soils and surround them, while the hydrophilic heads pull the surrounded soils off the surface and into the cleaning solution. Then the micelles reform with the tails suspending the soil in the center of the structure.
The hydrophilic head of each surfactant is electrically charged. The charge can be negative, positive, or neutral. Depending on the charge of the hydrophilic head, the surfactant is classified as anionic, nonionic, cationic or amphoteric.
Anionic surfactants have a negative charge on their hydrophilic end. The negative charge helps the surfactant molecules lift and suspend soils in micelles. Because they are able to attack a broad range of soils, anionic surfactants are used frequently in soaps and detergents. Anionic surfactants create a lot of foam when mixed. While anionic surfactants are excellent for lifting and suspending particulate soils, they are not as good at emulsifying oily soils.
Sulfates, sulfonates, and gluconates are examples of anionic surfactants.
Nonionic surfactants are neutral, they do not have any charge on their hydrophilic end. Nonionic surfactants are very good at emulsifying oils and are better than anionic surfactants at removing organic soils. The two are frequently used together to create dual-action, multi-purpose cleaners that can not only lift and suspend particulate soils, but also emulsify oily soils.
Certain nonionic surfactants can be non-foaming or low-foaming. This makes them a good choice as an ingredient in low-foaming detergents.
Nonionic surfactants have a unique property called a cloud point. The cloud point is the temperature at which the nonionic surfactant begins to separate from the cleaning solution, called phase separation. When this occurs, the cleaning solution becomes cloudy. This is considered the temperature for optimal detergency. For low foaming cleaners, optimal detergency is at the cloud point; for foaming cleaners optimal detergency is either just below the cloud point or at the start of the cloud point. The agitation of low foaming cleaners is sufficient to prevent phase separation.
The temperature of the cloud point depends upon the ratio of the hydrophobic and hydrophilic portions of the nonionic surfactant. Some cloud points are at room temperature while others are very high. Some nonionic surfactants don&#;t have a cloud point because they have a very high ratio of hydrophilic to hydrophobic moieties.
Examples of some common nonionic surfactants include cocamide, ethoxylates, and alkoxylates.
Cationic surfactants have a positive charge on their hydrophilic end. The positive charge makes them useful in anti-static products, like fabric softeners. Cationic surfactants can also serve as antimicrobial agents, so they are often used in disinfectants.
Cationic surfactants cannot be used with anionic surfactants. If positively charged cationic surfactants are mixed with negatively charged anionic surfactants, they will fall out of solution and no longer be effective. Cationic and nonionic surfactants, however, are compatible.
Examples of some common cationic surfactants include alkyl ammonium chlorides.
Amphoteric surfactants have a dual charge on their hydrophilic end, both positive and negative. The dual charges cancel each other out creating a net charge of zero, referred to as zwitterionic. The pH of any given solution will determine how the amphoteric surfactants react. In acidic solutions, the amphoteric surfactants become positively charged and behave similarly to cationic surfactants. In alkaline solutions, they develop a negative charge, similar to anionic surfactants.
Amphoteric surfactants are often used in personal care products such as shampoos and cosmetics. Examples of some frequently used amphoteric surfactants are betaines and amino oxides.
Surfactants are a key ingredient in cleaning products. One thing that differentiates cleaning products is how they are made. Cleaners made from a single chemical, targeting a specific type of soil, are referred to as commodity cleaners. Cleaners that are blends of various chemical ingredients designed to work together to remove various types of soils are referred to as formulated cleaners.
Formulated cleaners usually contain four basic elements: surfactants, hydrotropes, builders and carriers. Hydrotropes are chemicals that keep the otherwise incompatible surfactants and builders stable in a solution. The carrier is either water or a solvent. These elements work together to create mechanical actions to remove soils. The end result is a product that can attack dirt on surfaces with a variety of cleaning mechanisms including emulsifying, lifting, dispersing, sequestering, suspending and decomposing soils of various types. The type of surfactants used in a cleaning product largely determines which soils they will be best at removing.
