Saponification is the science of soap making
The process that makes the biggest difference in bar soap is saponification, the chemical reaction that transforms oils and fats into soap. Another important process is curing, where soap bars are left to dry and harden after saponification, affecting their texture and longevity.

Benefits of Using Cold Process Bar Soap
Indulging in cold-process bar soap is an investment in higher quality skincare. The gentle nature of cold process soap makes it an ideal choice for those with sensitive skin or allergies, offering a soothing cleanse without the harsh ingredients in commercial soaps. The high natural glycerin content, a byproduct of the saponification process, acts as a humectant, drawing moisture to the skin and providing deep, lasting hydration. Unlike soaps laden with synthetic fragrances and detergents, cold process soap relies on essential oils and plant-based components to cleanse and scent.
We make all of our soaps with oils made with natural ingredients. We do not use any stripping agents, drying detergents, or fillers.

Elaboration:
- Saponification: This is the core process where soap is created. It’s a chemical reaction where oils and fats are combined with a strong base, typically sodium hydroxide (lye), to produce soap and glycerol. The lye is consumed in the reaction, so none remains in the final soap bar.
- Curing: After saponification, the soap needs time to cure. During this period, the soap continues to dry out and harden, as excess water evaporates. Curing also influences the soap’s texture, making it harder and more durable.
- Other Processes: While saponification and curing are the main processes, other steps can further refine the bar soap. This can include milling or extrusion, which can create a denser, longer-lasting bar.
