The History of Soap: From Ancient Babylon to Modern Artisan Craft

The History of Soap: From Ancient Babylon to Modern Artisan Craft

The humble bar of soap has been a faithful companion to humanity for thousands of years. From its origins as a rudimentary mixture of fats and ashes to the luxurious artisan creations we enjoy today, the history of soap is as rich and varied as civilisation itself. As a British artisan soap maker, I find endless inspiration in the past, where ingenuity, practicality, and art intertwined to create this vital cleansing tool.

Ancient Beginnings: The First Soap Makers

Soap’s story begins in ancient Babylon, around 2800 BCE, where traces of soap-like substances were discovered on clay cylinders. Historical records suggest the Babylonians combined animal fats with wood ash and water to create a crude cleansing agent. Their recipes laid the groundwork for future soap-making techniques.

Further south, the Egyptians documented their own cleansing treatments around 1500 BCE in the Ebers Papyrus. These early soaps often included natural oils and alkaline salts, enhancing their cleansing and skin-conditioning properties. See the Ebers Papyrus’s recipes for oil-alkali cleansers

The Romans: Soap as a Luxury

While soap’s practical uses were acknowledged early on, it wasn’t until the Roman Empire (around 1st century CE) that soap-making began to resemble the craft we know today. Legend credits Mount Sapowhere animal fats mixed with ashes flowing into nearby rivers, as the site of soap’s discovery. Though the story remains unverified, Roman baths popularised soap, blending olive oil with ashes for personal hygiene.

Surprisingly, Roman soap was often reserved for the wealthy. It was considered an indulgence, with poorer citizens relying more on abrasive tools like strigils to cleanse their skin; delve into ThoughtCo’s overview of Roman oil-strigil hygiene.

Medieval Soap Making: A European Tradition

Following the fall of Rome, soap production found a new home in Europe. By the 7th century, Arab chemists mastered methods for crafting soap using alkali and olive oil. This technology spread to Europe, particularly Spain and Italy, where Castile soap—a pure olive oil soap—became renowned for its gentle properties. Today, Castile soap remains a beloved staple in many artisan collections. our handmade soap collection.

In the Middle Ages, soap making evolved further, becoming an essential trade in cities like Marseilles and Savona. These centres of soap production used Mediterranean olive oil to create high-quality products, which were exported across Europe.

The Industrial Revolution: Soap for All

The advent of the Industrial Revolution in the 19th century marked a turning point in soap’s history, as production moved from small workshops to factories. Chemical advancements, such as Michel Eugène Chevreul’s work on fatty acids, revolutionised soap making. His discoveries led to the development of cheaper and more efficient manufacturing processes and here we see Chevreul’s 1823 saponification breakthroughs.

During this time, soap transitioned from luxury to necessity, spurred by increased awareness of hygiene and public health. Brands like Pears began marketing glycerine-based soaps with translucent finishes, making them highly sought after among the Victorian elite. Pears’ glycerine soap innovation since 1807.

Artisan Soap Today: Crafting with Purpose

Fast forward to the present day, and soap has become an art form once more. While industrial soaps dominate supermarket shelves, artisan soap makers have rekindled traditional methods to create personalised, eco-friendly alternatives.

As a soap maker, I’m deeply committed to using natural ingredients, from nourishing butters to essential oils. Traditional cold process soap-making methods, which date back centuries, allow me to craft products that are not only gentle on the skin but also kind to the environment.

Moreover, sustainability is a cornerstone of modern artisan soap craft. By avoiding palm oil and choosing biodegradable packaging, small-scale producers are paving the way towards a cleaner planet. Organisations like Greenpeace emphasise the importance of sustainable practices in reducing deforestation caused by palm oil production and developed a 2025 report on palm oil deforestation.

Why Choose Handmade Artisan Soap?

Handmade soap offers a sensory experience that mass-produced bars simply cannot replicate. Every batch is unique, reflecting the care, creativity, and skill of its maker. From the invigorating scent of lemongrass to the creamy lather of shea butter, artisan soap transforms an everyday ritual into a moment of self-care.

Artisan bars also cater to diverse skin needs. Unlike commercial soaps laden with synthetic additives, handmade soap retains natural glycerine, a humectant that attracts moisture to the skin.

The Future of Soap Making

As we look ahead, the soap-making industry faces both challenges and opportunities. Environmental concerns, such as microplastic pollution and water conservation, are driving innovation in product formulation and packaging. Educating consumers about the benefits of traditional soap and sustainable practices remains essential as is this 2025 PMC study on (microplastics) MPs in skin cleansers.

Even amidst evolving tastes and trends, one thing remains clear: the art of soap making, with its emphasis on quality, creativity, and care, is here to stay. For those of us devoted to the craft, it’s a privilege to continue the legacy of soap makers who came before us, bringing beauty and functionality into people’s daily lives.

Conclusion

The history of soap is a testament to human ingenuity and adaptability. From ancient Babylon to the artisan soap studios of today, every era has added its own unique touch to this essential product. As we embrace modern advancements, the heart of soap making, combining art and science to create something truly beneficial, remains unchanged.

At The Humble Shepherd Co., we celebrate this rich heritage every day. Whether you’re seeking gentle cleansing options or a luxurious pampering experience, our handmade soap collection offers a range of beautifully crafted soaps that honour tradition while embracing sustainability.

Britain's Soap Making Heritage: From Victorian Factories to Artisan Studios

Britain played a central role in transforming soap from a cottage craft into a global industry. The story of Port Sunlight, the model village built by William Hesketh Lever in the Wirral in 1888, is perhaps the most vivid illustration of how soap shaped British industrial and social history. Lever Brothers developed Sunlight Soap, one of the world's first branded consumer products, and in doing so helped drive down the cost of cleansing to the point where clean hands and clean homes became a realistic aspiration for working-class families across the country.

Yorkshire tallow chandlers, London soap boilers, and the hard-water districts of the north all contributed regional character to British soap history. Before chemical soda ash was widely available, makers relied on wood ash lye, animal tallow, and whale oil — ingredients that shaped the texture and scent of early bars. The shift to vegetable oils and synthetic lathering agents during the twentieth century gave British consumers cleaner-smelling, longer-lasting bars, but at the cost of the natural glycerin and nourishing residuals that artisan methods preserve.

Today, a quiet revival is under way. Small-batch soap makers across the UK — from Cornwall to the Scottish Highlands — are returning to traditional cold process methods, plant-based oils, and locally sourced botanical ingredients. At The Humble Shepherd, that same ethos drives every batch. Each bar honours the long lineage of British soap craft while rejecting the shortcuts that industrial production demands: no detergent surfactants, no glycerin extraction, no synthetic hardeners. Just oils, lye, water, and time.

What Cold Process Soap Preserves That Industrial Manufacturing Strips Away

The single most important difference between cold process artisan soap and a commercial bar from a supermarket shelf is glycerin. During saponification, natural glycerin is produced as a by-product. In handmade soap, this glycerin remains in the bar — which is why a well-made cold process soap often leaves skin feeling noticeably less tight and dry after washing. In industrial manufacturing, that glycerin is extracted and sold separately to the cosmetics industry, leaving behind a leaner bar that requires added moisturising agents to compensate for what was removed.

Cold process also preserves the conditioning properties of each oil used in the recipe. Olive oil brings oleic acid, which mirrors the skin's own sebum. Shea butter contributes stearic acid and vitamins A and E. Castor oil helps build lather and adds draw. These qualities survive cold process manufacture because no external heat is applied after mixing — the saponification reaction generates its own warmth and the oils transform gently, without the thermal degradation that occurs when soap is boiled or spray-dried in industrial settings.

Finally, cold process soap requires a full cure — typically four to six weeks at minimum — during which excess water evaporates and the bar hardens and mellows. This patience is built into every bar at The Humble Shepherd Co. It cannot be rushed or replicated by a factory pressing out thousands of identical bars per hour. The cure is where the history of soap making lives on most honestly: in the waiting, the craft, and the bar that is better for it.

Frequently Asked Questions About the History of Soap

Q: When was soap first invented?

A: Archaeological evidence suggests soap-like substances were first produced in ancient Babylon around 2800 BCE, with clay tablets describing a mixture of water, alkali, and cassia oil. Ancient Egyptians also used similar cleansing pastes, and the Romans refined soap-making further after discovering that animal fat combined with wood ash produced an effective cleansing agent. The word "soap" itself is thought to derive from Sapo Hill in Rome, where animal sacrifices left fatty residues that mixed with ash to create early soap deposits found in streams below.

Q: What is the difference between artisan soap and commercial soap?

A: The fundamental difference lies in how glycerin is handled. Cold process artisan soap retains all the glycerin produced during saponification — the natural by-product that attracts moisture to the skin and creates a conditioning lather. Commercial soap manufacturers extract this glycerin to sell separately to the cosmetics industry, then add synthetic moisturising agents back into the bar. Artisan soap also uses carefully selected carrier oils chosen for their specific fatty acid profiles, whereas commercial bars often rely on cheaper commodity fats. The result is a product that nourishes as it cleanses, rather than simply removing dirt.

Q: Was soap always made from animal fat?

A: Historically, yes — tallow (rendered beef fat) and lard were the most widely available fats for soap-making throughout much of Western history, simply because they were plentiful by-products of the meat trade. British tallow chandlers built entire industries around this material. However, trade routes brought olive oil from the Mediterranean, coconut oil from tropical regions, and palm oil from West Africa into soap recipes over centuries. The modern artisan revival has moved decisively towards plant-based oils — olive, coconut, shea, castor, and sunflower — which produce gentler, vegan-friendly bars that align with contemporary values around animal welfare and sustainability.

Q: Why does handmade soap feel different to shop-bought bars?

A: Three factors account for the distinct feel: glycerin retention, oil quality, and cure time. Handmade cold process soap keeps all its naturally occurring glycerin intact, which draws moisture to the skin during and after washing — a quality absent in commercial bars where glycerin has been removed. The premium carrier oils used by artisan makers each bring specific skin-loving fatty acids that survive the cold process intact. Finally, a proper cure of four to six weeks allows the bar to harden fully and the lather to mellow into something noticeably creamier. The result is a bar that leaves skin feeling genuinely clean and comfortable rather than tight or stripped.
