ABSTRACT

Saponification is the process of converting fats or oils into glycerol and soap by reacting with alkalis such as potassium or sodium hydroxide. This process is crucial for understanding the chemical makeup of soap and its applications. This review article focuses on the product’s historical and modern applications while providing a thorough understanding of the chemistry and saponification process. This article explains the process of saponification, which turns natural fats or oils into soap and glycerol by using an alkali like KOH or NaOH. We explain the steps involved in saponification, which include the hydrolysis of the ester link, the creation of soap molecules, and the impact of the fatty acid chain on the soap’s properties. Glycerol, another economically useful byproduct, has multiple uses across many industries and a reputation for sustainability. We also assess the impact of several factors on the soaps, such as temperature, alkali content, mixing techniques, curing times, and additive usage. This paper reviews the valid literature in depth using a thorough historical, scientific, and industrial examination of soap manufacture, including saponification techniques and soap chemistry. Using the bibliometric approach, this review draws attention to the scientific and technological elements of soap manufacture, as well as its wide range of uses in the disciplines of pharmacy, hygiene, and cosmetics.

Keywords: Saponification, Soap chemistry, Alkali, Fatty Acids, Glycerol.
