What are surfactants? Anionic and Nonionic Surfactants

Anionic and Nonionic Surfactants are both substances that can be found in everyday products. These two types of surfactants have different properties, but they do the same thing: break down dirt and oil on surfaces due to their charge.

So before you go and buy another cleaning product, get familiar with these two types of household cleaning agents, and you can decide what is right for you and when.

What are surfactants

Surfactants are brilliant chemicals with two opposing ends. One end of the surfactant is soluble in water and the other in fat, which means they can help mix oils and waters that would normally sit on top of one another when you have a liquid sitting on top of an oil stain, for example, there’s lots surface tension between them.

This situation causes all sorts of problems such as reduced efficiency because it makes cleaning products less effective. By reducing this surface tension through using these clever little chemical cleaners we might be able to get rid of those pesky stains from our clothes much quicker!

Surfactants are beneficial chemicals that mix liquids together even if one has trouble penetrating into surfaces like oily ones do. In certain cases where both substances can’t be mixed, surfactants can work to break down the compounds of oily substances so that they are more easily penetrated by water. As a result, they are used in a vast array of different products, from soaps and detergents to household cleaners.

How are surfactants used in cleaning products?

The importance of both types of surfactants in everyday life and products we use every day, such as laundry detergents and other cleaning products. Without surfactants on a surface, all the dirt and oil would collect there instead of being washed away by water, but the surfactant keeps all this stuff from sticking together.

For example, toothpaste is a nonionic surfactant mixed with fluoride and flavoring, making it easier to brush your teeth. In addition, the fluoride in toothpaste will help kill bacteria on your teeth and make them stronger, so they don’t break down as fast; without the fluoride, the bacteria would stick to your teeth, and you wouldn’t be able to brush it away.

What is an Ionic surfactant?

Ionic Surfactants contain a charge which helps them break down dirt and oil on surfaces. They also mix well with water, but they don’t mix well with oils or other non-polar liquids because they repel each other (this is why you might see your hair frizz up when it gets wet). There are 3 types of ionic surfactants: Anionic, Cationic, Amphoteric.

Anionic Surfactants (negatively charged)

An anionic surfactant is a substance that breaks down dirt and oil on surfaces due to its negative charge. It mixes well with water, but it doesn’t mix well with oils or other non-polar liquids because they repel each other. They also stick to other things like dirt and grime because it has a negative charge.

Generally, these come in the form of salts with a negative charge. The salt attracts water and breaks down oil on surfaces like dishes, glasses, and tables because it has a negative charge. They are also used in washing detergent to break apart dirt and make it easier to wash away without sitting on your clothes or damaging them.

Where do you find Anionic Surfactants?

Anionic surfactants are chemicals that can be found in many everyday products. They are commonly used as laundry detergent, cleaning liquid, and washing powder. They can also be found in personal care products such as body wash, shampoo, or skin creams because they break down oil and clean dirt from your skin.

They can be made naturally or artificially. For natural anionic surfactants, saponin is a good example. It is used to naturally create foam in beer and can also be found in different kinds of soaps like Castile soap or Marseille soap. Anionic surfactants are commonly made from plants and animals.

Types of Anionic Surfactants

There are four main anionics: sodium lauryl sulfate (SLS), sodium laureth sulfate (SLES), ammonium lauryl sulfate(ALS), and ammonium laureth sulfate (ALES). Sulfates have a negative charge because they contain sulfuric acid groups (-SO3H); these types of molecules dissolve better than other compounds to create suds but also irritate the skin or hair follicles which causes dryness, among other things.


Cationic surfactants (positive charge)

Cationic surfactants are designed to cling onto fabrics and help them feel softer (like fabric softeners). Cationic surfactants also work as disinfectants, which kill off unwanted bacteria that cause odors or make you sick! They are most likely to be seen in fabric softeners and disinfectants.


Amphoteric surfactants (contains a positive and negative charge)

Amphoteric surfactants are the least potent of all personal care product cleaning agents. These surfactants can be found in shampoos and body washes, as well as handwashes that foam up nicely.


How do ionic surfactants work?

Ionic surfactants work by forming a layer of oil on top of the water. This way, the dirt, and grime will stick to the surfactant instead of collecting in your hair or on your skin. The charge also attracts water so that it can wash away with plain tap water without damaging anything around it. This is what makes them great in cleaning products.

Cleaning products like dish soap, laundry detergent, or washing powder use surfactants to remove dirt on dishes, clothes, and floors before it can set in and cause a permanent stain. Anionic surfactants can be harmful at higher concentrations because they will break down into nitrosamines, which are carcinogenic. Nitrosamines can cause cancer if they are absorbed by your body and work their way into your bloodstream.


What are nonionic surfactants?

Nonionic surfactants have no charge and are used in everyday products to keep things from sticking together. These surfactants can’t clean as effectively as an anionic surfactant, but they are much more compatible with other products.

They can’t clean as effectively as an anionic because they repel water, which is why they are typically found in toothpaste, shampoo, and conditioner. Nonionic surfactants are used in shampoo or conditioner because they won’t damage your hair as sulfates do. They are used in toothpaste to help ensure that it doesn’t have a bad taste and helps keep the paste from hardening.

Nonionic surfactants can be natural or artificial, but they are not chemically made most of the time, although some surfactants are. Most nonionic surfactants are made by mixing alcohols with ethylene oxide and propylene oxide, which is broken down into ethylene glycol.


How do nonionic surfactants work?

Nonionic surfactants work by lowering the surface tension of water so that it covers more area and is easier to clean. They also help make sure that all of the dirt and grime is washed away instead of just sitting on top of your skin or hair as anionic surfactants would do without damaging your hair or leaving a residue.

Nonionic surfactants are found in toothpaste, shampoo, and conditioner because they don’t damage the hair or leave a residue that would make your mouth feel weird, or your hair feels gross. They might not be as effective at cleaning as anionic surfactants, but they do a great job at doing what regular soap does without having all of the harsh effects that regular soap does.


Use of surfactants

Both anionic and nonionic surfactants are important in everyday life, and they can be found in many of the products we use every day. For example, cleaning products like dish soap, laundry detergent, or washing powder use anionic surfactants to remove dirt on dishes, clothes, and floors before it can set in and cause a permanent stain on your clothing or furniture. However, anionic surfactants can be harmful at higher concentrations because they will break down into nitrosamines, which are carcinogenic. Nitrosamines can cause cancer if they are absorbed by your body and work their way into your bloodstream.

Nonionic surfactants help make all kinds of products more appealing to use. For example, they are used in toothpaste because they won’t damage or irritate your teeth, help make sure that the toothpaste doesn’t have a bad taste, and help keep it from hardening over time. They are also found in shampoo or conditioner because they won’t damage your hair as sulfates do.


Anionic surfactants vs. Nonionic surfactants

Which one you choose depends on your needs but more often than not, most people have some sort of both anionic and nonionic surfactant laying around the house. The two are very common when it comes to cleaning products because of their ability to break down dirt.

There are some big differences between the two. However, anionic surfactants have a negative charge on them which makes them very effective at breaking down substances with high oil content like grease or oil. In contrast, nonionic surfactants don’t have any charge.

Anionic surfactants are typically used in harsher cleaning agents like industrial-strength cleaners, whereas nonionic surfactants are commonly found in fabric softener or skincare products.

As for household products, since both have a purpose, it really depends on your needs of what you might want, but most often than not, if you need something that is going to break down oils and greases, you will most likely go for anionic surfactants if you want something that’s a little bit more gentle on your skin, nonionic surfactants are the way to go.


Nonionic Surfactants and Anionic Surfactants Final Thoughts

Surfactants are used in cleaning products to reduce surface tension, helping to wash away oil and grease. There are four main categories of surfactants: anionic (most widely-used), cationic, amphoteric, and nonionic. Nonionic have the advantage of not forming soap scum in hard water; however, they also happen to be less potent than their counterparts. Anionics can cause skin irritation if too much is applied or it comes into contact with sensitive areas like eyes. Otherwise, it offers powerful cleansing agents that you might find around your home!

Your cleaners may be just as dangerous to your health as they are helpful. For example, the US law for labeling cleaning products only requires that a list of surfactants is provided without designating which cleanser made them harsh or allergenic. The EU also lacks this requirement and instead lists ingredients in an overall blend, not identifying whether they make it more harmful than useful!

Your cleaner might have some nasty surprises lurking inside its bottle, too: many don’t provide information about their individual cleansing agents/surfactant on either label or online documentation so you can avoid those with particular sensitivities (either chemically based or natural).
