Below, we’ll delve into the history of soap making and soap origins, including its ancient beginnings, evolution, and current trends.

Whether you're a history buff, a DIY enthusiast, or someone interested in the science behind what soap is made of, this comprehensive guide provides a detailed look into the world of soap.

History of Soap Making

Ancient Beginnings

The history of soap making stretches back thousands of years, with evidence of early soap-like materials found in ancient civilisations such as Babylon, Egypt, and Rome. So, when was soap invented?

The origin of soap is often traced to around 2800 BC in ancient Babylon, with records suggesting the use of a soap-like substance made from fats boiled with ashes. While it's difficult to pinpoint exactly who invented soap, many historians credit the ancient Babylonians as the first to develop a soap-like material for cleaning purposes.

In ancient Egypt, soap was made using animal fats and plant oils mixed with alkaline salts. This mixture was primarily used for washing wool and cotton in textile production, as well as for medicinal purposes. The Egyptians also utilised soap for personal hygiene, a practice that laid the groundwork for modern soap making.

The Romans further advanced the art of soap making. They created soap from tallow (animal fat) and wood ashes, which they used for bathing and washing.

Medieval and Renaissance Periods (476 AD - 1500 AD)

During the medieval period, soap making in Europe advanced. Soap was still primarily made from animal fats and ashes, but the processes became more sophisticated.

The Renaissance period saw soap becoming more widespread across Europe, with cities like Marseille in France and Savona in Italy becoming well known for their high-quality soaps.

It was during this time period soap became recognised not just for its cleaning properties, but also for its role in improving health and hygiene. Its use helped to reduce the spread of diseases and contributed significantly to public health.

Industrial Revolution (1760 - 1840)

The Industrial Revolution has a big impact on soap history. With industrialisation came the ability to mass-produce soap, making it more accessible and affordable to the general population.

The introduction of commercial soap brands revolutionised the market. Companies like Lever Brothers (now Unilever) in the U.K. and Procter & Gamble in the U.S. began producing soap on a large scale.

The industrialisation of soap production involved the use of new ingredients and techniques.

Sodium hydroxide (caustic soda) replaced traditional alkaline ashes, and the continuous process method meant that soap making could be more efficient. This period also saw the rise of branded soaps.

What Is Soap Made Of?

Soap is typically made from a combination of fats or oils, water, and an alkali such as sodium hydroxide.

The fats and oils, which can come from animal or plant sources, react with the alkali in a process called saponification to produce soap and glycerin.

Essential oils for soap making are often added to provide natural scents, while other additives like colourants, herbs, and exfoliants can add to the soap’s appearance and benefits.

Understanding how soap is made is crucial for both commercial manufacturers and home crafters, as the process involves careful measurements and precise chemical reactions.

Modern soaps may also include preservatives and stabilisers, but many artisanal soaps focus on natural ingredients for a more organic product.

Modern Uses of Soap

Soap has become an integral part of our everyday lives, and thanks to advancements in technology, there are now several modern uses of soap. Let’s take a look at some of the most common below.
