Soap, with its simple formula yet significant benefits, has played a crucial role in maintaining personal hygiene throughout thousands of years of human history. Although soap has become commonplace today, few are aware that before the invention of modern soaps, people primarily relied on water and other rudimentary methods to cleanse their bodies.
Primitive Soap and Bathing in Pre-Modern Times
Since ancient times, early civilizations recognized the importance of bathing. In the Indus Valley Civilization (around 2600 to 1900 BC), the area of Mohenjo-daro featured primitive public baths, believed to be among the first bathing systems in the world. However, during this period, bathing mainly relied on water without the assistance of effective cleansing agents.

Before soap became common for personal hygiene, “people had a very unpleasant smell,” according to Judith Ridner, a historian at Mississippi State University. This was because, at that time, soap had not yet been invented or widely used.
Prior to the invention of soap, ancient people employed various clever and natural methods to cleanse their bodies and belongings. Bathing with water was the simplest and most common method. People often bathed in rivers, lakes, springs, or in bathtubs made from natural materials.
The Simple Yet Effective Formula of Soap
Soap, although today it contains many additional ingredients, is fundamentally a simple chemical compound – the salt of a fatty acid. Soap is created by combining fat with alkali, a compound soluble in water. According to Kristine Konkol, a chemist at the State University of New York at Albany, soap works by separating dirt and oil from surfaces, thanks to the unique properties of soap molecules which have a hydrophilic head and a hydrophobic tail. This allows it to easily remove dirt when in contact with water.
Soap in Ancient History
Soap has been used for a long time, but tracing the origins of ancient soaps has proven challenging due to their perishable nature. According to Seth Rasmussen, a chemical historian at North Dakota State University, the earliest records of soap-like substances date back around 2500 BC in Mesopotamia. The Sumerians used sodium carbonate – a type of salt derived from plant ash – to cleanse their bodies and wounds.
Meanwhile, during the Akkadian Empire in the region of Mesopotamia, a mixture of date palm, pine cones, and tamarisk was used to create cleansing agents similar to soap. This formula contained basic components similar to modern soap: alkali from tamarisk, oil from date palms, and abrasives from pine cones.

Many cultures used clay or sand to rub on their skin to remove dirt and oil. Natural clays with high absorbency were effective for cleansing the skin. Ash from certain plants, when mixed with water, had mild alkaline properties that could also help remove grease and cleanse the skin.
The Discovery of Soap Through Practice
Although modern science did not exist in ancient times, people inadvertently created soap through daily activities. For instance, boiling animal fat with plant ash or washing greasy pans with wood ash could produce soap. These methods were present in civilizations like Babylon and Ancient Egypt. Additionally, the Egyptians used ingredients such as natron (salt), clay, and talc-based soapstone in their bathing rituals.
The Cleansing Methods of the Greeks and Romans
The ancient Greeks and Romans had a different approach to cleansing. Instead of using soap, they typically bath in water and then apply fragrant olive oil to their bodies. They then used a curved tool called a “strigil” to scrape off dirt and excess oil. However, this method leaned more towards fragrance than effective cleaning.

Many herbs possess antibacterial and natural cleansing properties. These herbs were often boiled to create bathing water or crushed to be rubbed on the skin.
The Development of Soap in the Modern World
For thousands of years, soap was primarily used for cleaning textiles and had more industrial properties than personal hygiene. It wasn’t until the 19th century that soap became more popular in personal bathing routines. According to Ridner, the rise of soap in personal hygiene was attributed to several factors, including the Industrial Revolution, the availability of cheap fats, and the awareness of hygiene importance in hospitals after wars.
As manufacturers like Procter & Gamble began to capitalize on this demand, soap quickly became a mainstream product. Engineers and city reformers also contributed to promoting clean bathing, especially in immigrant communities, helping soap become an essential part of modern life.

From the primitive soaps accidentally created in ancient civilizations to the modern soap products we use today, the development of soap is a long and fascinating story. Nowadays, with advanced and diverse formulas, soap has become an indispensable part of daily life, contributing to health protection and improving the quality of life for humanity.
