🧴 Cold Process Arabic Soap – Production, Formulation and Properties
Overview:
Cold Process Arabic Soap is a natural, handmade liquid soap produced through a low-temperature saponification method, where vegetable oils react with potassium hydroxide (KOH) without external heating.
This method preserves the natural glycerin and nutrient content of the oils, resulting in a gentle, moisturizing, and eco-friendly soap suitable for both personal and household cleaning applications.
Cold process Arabic soaps are valued for their smooth texture, authentic formulation, and mild cleaning performance, making them ideal for artisanal and small-scale manufacturing.
Production and Formulation:
In the cold process method, carefully measured vegetable oils such as olive, coconut, or sunflower oil are saponified by slowly mixing with an aqueous KOH solution at room temperature.
No heating is applied, allowing the natural glycerin formed during the reaction to remain within the soap.
After saponification, the soap mixture is stirred until trace formation, then left to rest and cure for several days to ensure complete reaction and stability.
Optional additions such as essential oils, natural colorants, or plant extracts can be incorporated to enhance the final product’s aesthetic and functional qualities.
