Cold process soap making is the original, traditional method of making soap by combining fat or oil (animal or plant based) with sodium hydroxide lye then blending in addition of essential oils and colorants as required. This treatment causes a chemical reaction called saponification followed by a curing time of 6 to 8 weeks. This method retains natural glycerine which acts as a humectant, making the soap moisturizing.

Normal soaps (like commercially produced bars) are typically made using a process that involves heating, while cold process soaps are made without external heat, allowing the saponification reaction to occur naturally at room temperature. Cold process soap often results in a more moisturizing, smoother bar and is considered more natural due to preserving the beneficial properties of oils and additives. 

Yes, cold process soap naturally contains glycerine.

Cold process soap offers several benefits, primarily due to its gentle making process and the preservation of natural ingredients. These soaps tend to be milder, more moisturizing, and suitable for sensitive and dry skin as well.
