To make soap, the basic method involves mixing lye (sodium hydroxide) with water to create a lye solution, then blending it with oils or fats. The mixture undergoes a chemical reaction called saponification, turning into soap after it thickens and is poured into molds to harden and cure. Here is a summarized cold process soap-making guide:
- Prepare the lye solution by slowly adding lye to water (never the reverse) and let it cool.
- Melt solid oils and combine with liquid oils, heating to about 100°F (38°C).
- When both the oils and lye solution are roughly the same temperature, mix them using an immersion blender until the mixture thickens to a "trace" stage (like pudding consistency).
- Add essential oils or colorants if desired.
- Pour the mixture into molds, cover, and insulate for 24-48 hours for initial hardening.
- Unmold the soap, cut into bars, and cure for about 4-6 weeks to complete saponification and drying.
Essential safety measures include wearing gloves and goggles when handling lye, as it is caustic. This process can vary slightly by recipe (hot process speeds curing by applying heat, for instance) but this cold process method is common for homemade soap. If desired, a simple recipe would use coconut oil, olive oil, distilled water, and sodium hydroxide (lye), with optional fragrance oils or natural colorants.
