What’s the Difference Between Laundry Soap and Detergent

When it comes to doing the laundry, most people just don’t know the difference between laundry soap and detergent. What is the difference, you ask? Laundry soap is a type of soap that is used to clean clothes. It is made up of natural or synthetic ingredients that help remove dirt and stains from fabric. Detergent, on the other hand, is a type of cleanser that is used to remove grease, oil, and dirt from surfaces. It is made up of synthetic chemicals that can be harmful if ingested. So, now that you know the difference between these two types of cleaners, which one should you be using for your laundry?

What’s the Difference Between Laundry Soap and Detergent?

What’s the Difference Between Laundry Soap and Detergent

Let’s start with the basics and get a little technical. Both soap and detergent are surfactants—they work by reducing surface tension between two liquids or a liquid and a solid, allowing dirt particles to be more easily removed from fabric fibers. But while they both have similar effects on our clothes, they do so in different ways.


Soaps are actually made from fatty acids derived from animal fat or vegetable oils, which act as a base for cleaning agents known as anionic surfactants.

These surfactants bond with oil and water molecules in order to lift dirt away from fabrics and suspend it in solution until it can be rinsed away.

This makes soap an effective cleaner for materials like wool or cotton that can be damaged by harsher detergents.

Laundry soap is a traditional form of cleaning agent made primarily from natural ingredients such as plant oils and fats, lye, and water.

It is usually sold in solid bar form or as flakes that you can dissolve in hot water to make a soapy solution. Laundry soap has been around for centuries and its basic formula hasn’t changed much over time – with one big exception: many modern laundry soaps are now scented with fragrances to make them more pleasant to use.


Detergents, meanwhile, contain synthetic ingredients like sodium lauryl sulfate (SLS) that act as cleansing agents but don’t require fatty acids for their production process.

Since this type of cleaner doesn’t rely on natural fats or oils for effectiveness, it’s generally better at removing grease and oily stains than soap is—making it ideal for synthetic fabrics like polyester or nylon that tend to attract oil-based stains more easily than natural fabrics do.

Detergent is a relatively new invention compared to laundry soap; it first appeared on the market in the early 20th century.

Unlike laundry soap, detergents contain synthetic substances such as petroleum-based surfactants (which help remove dirt) and other chemical additives that give them their cleaning power.

While detergents can be effective at removing dirt from fabrics, they also leave behind residue on clothing that can cause skin irritation or allergic reactions in some people.

It also tends to rinse out of clothes more quickly than soap does, which minimizes any potential damage caused by its residue being left behind on the fabric after laundering.

What Are The Ingredients In Laundry Soap And What Do They Do?

Laundry soap usually contains fatty acids, sodium hydroxide (lye), and water. The fatty acids are used as a surfactant, meaning they reduce the surface tension between water and oil molecules so dirt can be more easily lifted away from fabrics during the washing process.

Sodium hydroxide is used as a pH adjuster and helps the soap dissolve in water. The combination of these ingredients creates a mild cleanser that is effective at removing dirt, grease, and odors from fabrics without damaging them.

What’s The Difference Between Liquid And Powder Laundry Soap?

Difference Between Liquid And Powder Laundry Soap

The laundry aisle in your local grocery store can be a confusing place. So many choices! But which type of laundry soap should you choose? Liquid or powder? It may seem like a small decision, but it can have a big impact on your wallet and the environment.

Price Point Comparison

When it comes to price points, powder is usually cheaper than liquid laundry soap. This is because powder detergent is much more concentrated than liquid detergent, meaning that less is needed per load of laundry.

That said, some people find that they prefer liquid detergent because it is easier to measure out with a measuring cup instead of having to guess how much powder is needed for each load.

So when comparing prices, consider what will work best for you and how often you plan on doing laundry before making a purchase.

Environmental Considerations

When it comes to environmental considerations, both types of detergent can be eco-friendly if purchased from brands that use sustainable packaging materials and do not contain harsh chemicals or fragrances.

Additionally, studies have found that liquid detergents are generally more energy efficient than powders since liquids require less water for rinsing away suds during the washing cycle — something important to keep in mind if you live in an area with limited access to clean water resources.

Cleaning Power

Finally, when it comes down to it, the most important factor when choosing either liquid or powder laundry soap should be its cleaning power — do they both get your clothes clean as expected?

Generally speaking, yes! Both types of detergents are capable of getting your clothes clean as long as they are used correctly (meaning following instructions on proper amounts per load).

However, some experts suggest that powder detergents may have an edge over liquids due to their higher active ingredient content relative to liquids which means they can better dissolve dirt and stains from clothing fibers during washing cycles — something worth considering before making your purchase decision.

How Do I Choose The Right Laundry Soap For My Needs?

The best way to choose the right laundry soap is to consider what type of fabrics you’ll be washing, since some materials are more delicate than others.

If you’re washing delicate items like wool or silk, a milder soap like laundry soap is usually the safest option since it won’t strip away the natural oils in these fabrics and cause them to become brittle or prone to tearing.

For tougher stains, like grease or oil-based ones, a detergent is usually your best bet since it’s designed specifically to break down these types of substances.

It’s also important to consider any allergies or sensitivities you may have to detergents and other cleaning agents when choosing a laundry soap. If you’re unsure what product is right for you, talk to your doctor or dermatologist about which product will be the safest for your skin.

Therefore, if you’re looking for an effective way to clean your clothes without harsh chemicals, then laundry soap may be the right choice.

However, detergent may be the better option if you prefer using something more powerful than soap but don’t want to sacrifice safety.

Ultimately it comes down to what works best for you – so don’t be afraid to experiment until you find the perfect cleaner for your clothes!

Can I Use Detergent To Wash My Clothes If I Don’t Have Any Laundry Soap?

Yes, you can use detergent to wash your clothes if you don’t have any laundry soap. Detergents are specifically designed to remove dirt and stains from fabrics, so they are a suitable alternative to using laundry soap.

When using detergent instead of laundry soap, be sure to follow the instructions on the package carefully to ensure that you’re using the correct amount per load.

Excessive amounts of detergent can leave a residue on your clothing and may even damage some fabrics, so it’s important to be mindful when measuring out how much detergent to use.

Overall, both laundry soap and detergents are effective cleaning agents and can be used to get your clothes clean — it just depends on what type of fabrics you’re washing and what kind of allergens or irritants you’re trying to avoid.

However, if you’re looking for a more eco-friendly option, then laundry soap may be the better choice for you.


When it comes to choosing between laundry soap and detergent there’s no “right” answer; both have their own benefits and drawbacks depending on what type of fabrics you’re washing and what kind of results you’re looking for.

In general, though, if you want something gentle yet effective then choose laundry soap; if you need something stronger then opt for detergent instead!

No matter which one you choose make sure it’s compatible with the fabric care instructions of whatever item(s) of clothing you’re looking to clean!
