INTRODUCTION

If you look up detergent in a dictionary it is simply defined as cleaning agent. During the last two to three decades, however, the word detergent has tended to imply synthetic detergent, or syndet for short, rather than the older soap. In fact, commercial formulations consist of a number of components, and we shall use the term surface-active agent, or it's abbreviation surfactant, to describe the special active ingredients that give detergents their unusual properties. Synthetic detergents dissolve or tend to dissolve in water or other solvents. To enable them to do this, they require distinct chemical characteristics. Hydrophilic (water loving) groupings in their molecular structure, and hydrophobic (water hating) groupings, help the detergent in it’s “detergency” action. The first soaps were manufactured in ancient times through a variety of methods, most commonly by boiling fats and ashes. Archaeologists excavating sites in ancient Babylon have found evidence indicating that such soaps were used as far back as 2800 B.C. In Europe, the use of soap declined during the Middle Ages. However, by...
