The Secret Behind Our Castile Soap
When it comes to natural skincare, few ingredients are as time-tested, effective, and versatile as saponified olive oil. This powerhouse ingredient is the foundation of our body, hand & face wash, and it plays a crucial role in what makes our Castile soap so gentle yet effective.
But what exactly is saponified olive oil? Why has it been used for centuries? And how does it benefit your skin? In this blog, we’ll explore its history, science, skin benefits, and why it deserves a permanent place in your daily skincare routine.
What Does “Saponified” Really Mean?
Saponified olive oil is simply olive oil that has been transformed into soap through a natural process called saponification. This happens when olive oil is mixed with water and a natural alkaline agent. During this reaction, the oil turns into soap and glycerin.
Even though it sounds technical, this process has been used for thousands of years. Long before commercial cleansers existed, people relied on this method to create gentle, effective soap using only plant-based ingredients.
The magic happens when the natural glycerin stays in the final product. Unlike mass-produced soaps that remove it, traditional Castile soap keeps glycerin intact, making it naturally moisturizing.
A Journey Through History: Olive Oil in Skincare
Olive oil has been cherished since ancient times. The Mediterranean region, home to endless olive groves, cultivated this golden oil not only for cooking but also for beauty and medicine.
One of the oldest known soaps in history is Aleppo soap, dating back over 4,000 years. Made primarily with olive oil, it laid the foundation for what we now know as Castile soap. Later, in Spain’s Castile region, artisans refined the formula, creating an even purer version made exclusively with olive oil.
During the Middle Ages, Castile soap became a luxury item across Europe. Royal families favored it for its gentle cleansing properties and silky feel on the skin. While trends have changed, the formula remains timeless.
Today, this ancient tradition lives on in our modern skincare routines.
Why Your Skin Loves Saponified Olive Oil
One of the biggest reasons this ingredient stands out is its ability to cleanse without stripping your skin. Many commercial body washes use harsh detergents that remove natural oils, leaving skin tight and dry. Saponified olive oil works differently. It gently lifts away dirt and impurities while respecting your skin barrier.
This makes it especially beneficial for people with dry or sensitive skin. Instead of feeling squeaky clean, your skin feels soft, comfortable, and hydrated.
Olive oil is also naturally rich in antioxidants like vitamin E and polyphenols. These help fight free radicals that contribute to premature aging. Over time, consistent use can support smoother, healthier-looking skin and improve elasticity.
Another incredible benefit is its soothing nature. If you deal with redness, irritation, eczema, or itchiness, olive oil soap can feel incredibly calming. Its anti-inflammatory properties help reduce discomfort and support skin recovery.
And let’s not forget its mild antibacterial effects. While it’s gentle, it still cleans effectively, making it suitable for acne-prone skin without causing excessive dryness.
Why We Chose It for Our Body, Hand & Face Wash
Our philosophy is simple: skincare should be clean, effective, and honest. That’s exactly why saponified olive oil is the foundation of our Castile soap. We believe in ingredients that truly work, without unnecessary fillers or complicated formulas.
When we created our cleanser, we wanted something that could be used by everyone—from sensitive skin to daily, whole-family use. Saponified olive oil checks every box. It’s plant-based, biodegradable, cruelty-free, and gentle enough for all skin types. But most importantly, it actually delivers results.
Instead of overloading our formula, we focused on a small selection of powerful natural ingredients that complement each other perfectly. Our Castile soap is made with just five:
Our body, hand, and face washes are made with the same ingredients, but in different ratios. This allows each product to adapt better to specific skin needs. That said, every formula is safe to use all over your body (so yes, you can absolutely use the face wash on your body too).
Choosing a multi-purpose cleanser also means simplifying your routine. One product for your face, body, and hands saves time, reduces clutter, and cuts down on waste. Minimalist skincare at its best.
We’re currently offering a limited edition packaging option with aluminum bottles for your sink and glass gallons for families. This is perfect if you love reusing containers and reducing plastic. Plus, the gallon lasts forever (okay, not literally—but close 😉).
Once this packaging sells out, it won’t be back, so it’s a great opportunity if you want to make a more sustainable choice.
Fun Facts About Olive Oil Soap
Did you know that Queen Cleopatra was rumored to bathe with olive oil-based soaps? Or that traditional Castile soap takes up to six weeks to cure properly before it’s ready to use?
Another interesting fact is that olive oil soap produces a softer, creamier lather than synthetic cleansers. It may not foam aggressively, but that’s actually a good thing. Excess foam often means added detergents that can irritate skin.
People around the world also use Castile soap for more than just skincare. It’s a favorite for natural household cleaning, laundry, and even pet care. That’s how gentle and versatile it is.
A Sustainable Choice for Your Routine
Choosing products made with saponified olive oil isn’t just good for your skin, it’s good for the planet too. Olive oil is a renewable resource, and Castile soap is fully biodegradable.
Unlike conventional cleansers, it doesn’t release harmful chemicals into the water system. There are no microplastics, no synthetic fragrances, and no unnecessary fillers.
Traditional soap-making methods also use less energy than industrial manufacturing, making this ingredient a smart choice for conscious consumers.
Is It Safe for Daily Use?
Absolutely. When soap is properly formulated, there is no lye left in the final product. It’s fully neutralized during saponification, making it completely safe for skin.
That’s why Castile soap is often recommended by dermatologists and suitable even for babies. It’s hypoallergenic and gentle enough for daily cleansing.
If you struggle with eczema, psoriasis, rosacea, or chronically irritated skin, saponified olive oil can help calm and comfort your skin.
Final Thoughts
Saponified olive oil isn’t just another trending skincare ingredient—it’s a timeless essential. Backed by centuries of use and loved across generations, it proves that the simplest solutions are often the most powerful ones.
If you’ve been on the fence about adding it to your routine, consider this your sign. Few ingredients can cleanse, hydrate, soothe, and protect your skin all at once. Its versatility, gentle nature, and proven benefits make it a true multitasker in skincare.
Sometimes, the best upgrade to your routine isn’t adding more products, but choosing better ones. And saponified olive oil is exactly that—a smarter, more thoughtful choice for your skin.
Once you experience the difference, you’ll understand why this ingredient has stood the test of time.
