What Most People Don't Know About Soap
by Tamara Neale
If you've ever picked up a bar from a grocery store shelf and assumed it was soap, you're not alone. Most people don't realize that many cleansing bars sold today aren't technically soap at all.
As someone who has spent years formulating, making, curing, testing, and selling traditional cold-process soap, I think understanding the difference matters—not because one product is inherently "good" or "bad," but because consumers deserve to know what they're buying and putting on their skin.
First Things First: What Is Soap?
Real soap is created through a chemical reaction called saponification.
Despite what social media sometimes suggests, you cannot make soap without lye.
Lye (sodium hydroxide) combines with oils and butters to create an entirely new substance: soap.
No lye = no soap.
It's that simple.
This process has been used for thousands of years. Ancient civilizations understood that combining alkaline materials with fats created a substance capable of lifting dirt and oil from the skin.
Today, the chemistry hasn't changed.
Whether a soapmaker is crafting a batch in a small studio in Tofino or a factory is producing thousands of bars, real soap still requires oils, lye, water, and time.
Why Some Bars Aren't Technically Soap
Many commercial cleansing bars are formulated with synthetic detergents rather than soap created through saponification.
You'll often see ingredients such as:
- Sodium Lauroyl Isethionate
- Sodium Cocoyl Isethionate
- Sodium Lauryl Sulfate
- Cocamidopropyl Betaine
These ingredients are surfactants. Their job is to cleanse.
There's nothing inherently wrong with them. Many are considered safe and are used in everything from shampoos to facial cleansers.
But they are not soap.
This distinction is so significant that in some jurisdictions manufacturers cannot legally market certain detergent bars simply as "soap."
That's why you'll often see terms like:
- Beauty Bar
- Cleansing Bar
- Moisturizing Bar
- Beauty Wash Bar
instead of soap.
Why Traditional Soap Feels Different
Traditional soapmakers have an advantage.
We can build the entire recipe around the properties of oils and butters.
Olive oil contributes a creamy, conditioning lather.
Coconut oil creates cleansing power and bubbles.
Sunflower oil adds skin-loving fatty acids.
Cocoa butter contributes hardness and longevity.
Different combinations create different experiences.
Soapmaking is part chemistry, part craftsmanship.
A recipe can look beautiful on paper but perform poorly in the shower. Achieving the right balance between cleansing, lather, hardness, longevity, and skin feel takes years of formulation and testing.
Then Comes the Waiting
This is the part many consumers never see.
At The Hobbyist, our botanical soaps cure for three to five weeks before they're ready for use.
Why?
Because water needs time to evaporate.
The crystalline structure of the soap continues to develop.
The bar becomes harder, longer-lasting, and milder.
A freshly made bar and a properly cured bar are not the same product.
Time is one of the most important ingredients in traditional soapmaking.
Unfortunately, it's also the ingredient that can't be rushed.
Reading a Soap Label Like a Soapmaker
If you're curious whether you're holding a true soap, look at the ingredient list.
Traditional cold-process soap often includes ingredients such as:
- Olive oil
- Coconut oil
- Sunflower oil
- Shea butter or cocoa butter
- Water
- Sodium hydroxide (or "saponified oils")
You may also see clays, botanicals, essential oils, salts, charcoal, or natural colourants.
If the ingredient list begins with a long list of synthetic surfactants, you're likely holding a detergent bar rather than a traditional soap.
Again, that's not necessarily a criticism.
They're simply different products made using different methods.
Why We Still Make Soap the Slow Way
Every botanical soap we make begins with oils, water, lye, and patience.
We use ingredients such as organic olive oil, coconut oil, sunflower oil, cocoa butter, mineral-rich clays, botanicals, and pure essential oils inspired by life on the coast.
Then we wait.
Weeks later, those bars are cut, stamped, wrapped, and sent out into the world.
In an age of automation, shortcuts, and mass production, there is something deeply satisfying about a process that still relies on chemistry, craftsmanship, and time.
Real soap has been made this way for centuries.
And in our little corner of Tofino, it still is.
