How is glycerin made and why is it important?

Glycerin is a natural byproduct formed during the saponification process, where fats or oils react with an alkali to create soap. In this chemical reaction, triglycerides break down into soap molecules and glycerin. Glycerin is highly beneficial for the skin due to its humectant properties, meaning it attracts and retains moisture. This helps to keep the skin hydrated, promoting a soft and supple complexion. 

However, many commercial soap companies extract glycerin from their products to be used in other applications, leaving their store-bought soaps devoid of this moisturizing component. As a result, these mass-produced soaps can be drying to the skin. To compensate, these companies often incorporate glycerin into lotions and skincare products, creating a cycle where consumers may feel the need to purchase additional items for adequate skin hydration. Handmade soaps, on the contrary, typically retain glycerin, offering a more moisturizing and nurturing cleansing experience without the need for extra products.
