What is Cold Process Soap?
Cold Process Soap is a traditional method of soapmaking where nourishing oils and butters are combined with a water–sodium hydroxide solution, triggering saponification—the chemical reaction that creates real soap and natural glycerin.
Unlike other methods, no external heat is used. The mixture is poured into molds and left to cure for 4–6 weeks, allowing water to evaporate creating a harder, longer-lasting bar.
Benefits of Cold Process Soap:
• Allows artisans to choose natural ingredients, colorants, and essential oils to create soaps with specific benefits (moisturizing, exfoliating, clarifying, etc.).
• No sodium hydroxide remains after about 48 hours—only gentle, skin-loving glycerin.
• Ingredients retain their beneficial properties because no extra heat is applied.
• Produces a smooth, creamy texture with a rich, luxurious lather.
• Cleanses without stripping the skin’s natural acid mantle.
• Has a pH where bacteria can’t survive
(not labeled “antibacterial,” but great for kitchens and bathrooms).
