Palm kernel oil has both the gentle moisturizing of palm oil and the foaming and cleansing power of coconut oil. It can be said that it has the advantages of both coconut oil and palm oil, and its nutritional content is higher than that of palm oil, and its hardness is also improved. Larger than palm oil. If cost is not a consideration, palm kernel oil is the best choice for making cold process soap that combines the advantages of coconut oil and palm oil!
Mix sodium hydroxide powder and water in a certain ratio (usually 1:1) to form a sodium hydroxide solution. This step needs to be done in a well-ventilated area, and you need to wear gloves and a mask to prevent sodium hydroxide from causing damage to the skin.
Saponification reaction: When sodium hydroxide solution encounters grease, a saponification reaction will occur to generate fatty acid salts with washing functions. During this process, some other ingredients, such as salt or other alkaline substances, are usually added to promote the reaction.
Stirring and cooling: In order to ensure that the saponification reaction proceeds smoothly, the mixture of sodium hydroxide and oil needs to be constantly stirred. Stirring helps reduce the temperature of the mixture, preventing dangerously high temperatures or affecting the quality of the final soap.
Mold placement and saponification completion: When the viscosity of the soap solution increases and appears solid like tofu curd, it indicates that the saponification reaction is complete. At this point, the soap solution can be poured into the mold and allowed to cool and solidify naturally to form soap.
Finished Cutting: After saponification is complete, remove the soap from the mold and cut it. The cut soap can be used directly or allowed to dry for a period of time in a cool place for further maturation.
During the production process, it is necessary to pay attention to safety and hygiene to avoid injuries caused by sodium hydroxide splashing. At the same time, attention should be paid to controlling the reaction conditions, such as temperature and time, to achieve the best saponification effect.
The basic steps of making soap include preparing raw materials, dissolving alkali, saponification reaction, stirring and cooling, saponification in molds, cutting and drying of finished products.
