The Soap Factory's Silk Series Soaps are meticulously produced using the cold process method. This method is quite common in soap making and involves mixing oils with a sodium hydroxide solution at room temperature. The cold process preserves the soap’s natural moisturizing properties and the benefits of sensitive ingredients like essential oils or herbal extracts. This method allows for great creativity in soap production, but it requires a slightly longer time for the soaps to be ready for use.
