Ingredients Required For Cold Process Soap Making

Every ingredient in this cold process soap-making method adds something to the soap; they help to bind it, give it a glossy texture and smell, and have health benefits for the consumer. Let's look at some of the materials' positive features in this cold soap-making procedure.

Cold process soap ingredients

Sodium Hydroxide: Sodium hydroxide is a catalyst or a material that is used to generate other compounds in a chemical reaction. Saponification is caused by caustic soda, which is an important element in soap production. A lye solution is formed when sodium hydroxide flakes or beads are introduced to a liquid.

Distilled Water: The sodium hydroxide lye is dissolved in water so that it can mix with the soaping oils and begin the polymerization reaction. Some of the water evaporates while the soap dries, resulting in a firmer, longer-lasting bar of soap.

Virgin Coconut Oil: In soap, virgin coconut oil acts as a cleaner. This indicates that it is primarily a substance that has the ability to purify the skin of bacteria and filth. In addition to being cleaner, coconut oil in soap has other properties. One of the very few oils that produce huge bubbles is coconut. This oil is also known as cold process soap oil.

Shea Butter: Shea butter is a triglyceride fat-containing stearic and oleic acid that comes from the African shea tree. This means it's ideal for making soap. Oleic acid adds to a solid lather while nourishing, hydrating, and making skin creamier texture and smoother.

Virgin Olive Oil: Virgin olive oil produces a hard, long-lasting soap with a soft washing lather that is ideal for all skin types, even those with sensitive skin. Olive oil soap is high in Oleic acid, which helps to nourish and moisturize your skin.

Castor Oil: When castor oil is added to a soap formulation, it produces a stable, rich, and creamy lather. It does, however, contribute moisturizing properties to soap. It's thick and sticky right out of the bottle, but it absorbs quickly into the skin. Castor oil is also known as cold process soap oil.

  • Stainless steel pan - For melting the solid oils

Process of Cold Soap Making

Preparing your homemade cold processed soap may appear difficult if you're a newbie, but it's actually fairly simple. Let's talk about some easy-to-follow cold process soap-making recipes you can try.

Process Of Making cold Process soap
  1. Gather your tools and materials and set up your workstation. Put on an apron, rubber gloves, and eye protection. Pre-measure the components with care. The solid oils should go into the pan, the liquid oils should go into a jug, the water should go into another heat-resistant jug, and the lye should go into yet another container.
  2. Make sure your recycled soap mold is ready. Wipeout an empty beverage carton and hang it upside down to dry. Cut out the side with the pouring spout when it's completely dry. For this, a slicing blade is preferable to scissors. Block the open end of the box with a portion of the cut-out material. This aids in the creation of a level surface on that side of the mold, as opposed to a quirky form resulting from the curvature of the top.
  3. The lye (Sodium hydroxide) granules should then be dissolved in water. Pour the lye granules into the water in a well-ventilated area, preferably outside. Be cautious because there will be a lot of energy and vapor. Make an effort not to inhale it. To cool, set outside in a safe location or in a deep basin of water.
  4. In a stainless pan over extremely low heat, melt the solid oils. Remove from heat and set on the potholder once the chocolate has melted. Pour the liquid oils into the container. If you're using the same bottle for the olive and castor oils, combine them first before pouring them into the pan. Castor oil is somewhat sticky, so mixing it with a lighter oil makes it simpler to pour.
  5. The temperature and pressure of the lye water and the oils should be recorded. You should aim for a temperature of 35-38°C for each of them.
  6. Put the lye mixture into the oil-filled pan. To catch any undissolved lye, I recommend straining the liquid through a sieve.
  7. Put your immersion blender into the pan and whisk the mixture while it is switched off. Next, pull it to the center of the pan and, using both hands, hold it on the pan's bottom for a few seconds to blitz it. Turn it off and use the blender as a spoon to mix the soap batter. Continue until the mixture reaches trace thickness. When the mixture leaves a distinct trail on the surface, this is what it means. It will have the consistency of thin custard.
  8. Put the soap into the mold as quickly as possible. To settle it, give it a tap.
  9. Put the soap in the freezer and keep it there overnight for a completely pure white soap. Alternatively, you can leave the soap on the countertop during this time. If the home is warm, there's a chance the center will melt and your bars will be slightly darker in the middle.
  10. Pull the soap out of the freezer the next day and lay it aside to rest another day. You can remove the soap out of the mold and cut it into bars with a kitchen knife once 48 hours have passed. This recipe will provide 6 to 8 decent-sized soap bars.

It must be cured for a period of 28 days. Curing entails spacing the bars out on a sheltered surface away from direct sunlight and in a ventilated area. This permits the excess water to evaporate completely. Here are detailed directions for curing soap. Your soap will last for up to two years after it is produced.


The cold process is an excellent alternative if you want to customize your soap down to the last ingredient. You get to pick the oils, colorants, fragrances, and other ingredients. You can begin getting imaginative with the patterns once you've found your perfect recipe.

Oils and sodium hydroxide lye are combined to make cold process soap. Saponification is the result of this chemical process. If you're searching for natural soap, give this recipe a try because it's inexpensive, enjoyable, and healthful.

FAQ: Cold Process Soap Making

Q1. How long does cold process soap take to cure?

Ans. Patience is required while making cold process soap. In the mold, it takes several days to harden. After that, it must be let to cure for 4-6 weeks to allow the extra water to drain. Curing makes the bar firmer and allows it to last longer in the shower.

Q2. Is melt and pour soap better than cold process soap?

Ans. If larger ingredients are not introduced at a lower temperature, they will sink to the bottom of the soap. Melt-and-pour soap hardens and cools quickly. This implies that some spirals that can be done with cold process soap can't be done with melt and pour soap. If melted and poured soap gets too hot, it can burn.

Q3. What is the fastest way to cure cold process soap?

Ans. Reduce water consumption in the mixture by 7-10% to speed up the cure time. Because the lye and oil amounts remain constant, there is no risk of the soap turning lye-heavy and harsh.

Q4. Cold Process Vs Hot Process.

Ans. The components are added at the conclusion of the cooking phase in hot process soaps. The ingredients are added to cold process soaps while the soap remains fluid, resulting in a smoother finished product.
