In this article, we will show you how to make your own soap at home using three different methods: cold process, melt and pour, and hot process. We will also give you some tips on how to choose the best ingredients for your soap, how to use various additives to enhance your soap, how to package and store your soap properly, and how to answer some common questions about soap making. So let's get started!
Section 1: The Cold Process Method
The cold process method is one of the most popular and traditional ways of making soap. It involves mixing fixed oils (such as olive, coconut, or palm oil) with an alkali (such as sodium hydroxide or lye) in a precise ratio. The result is a chemical reaction called saponification, where the oils and the lye combine to form soap and glycerin. The soap is then poured into a mold and left to harden for several hours or days. The soap is then cut into bars and cured for four to six weeks to allow the excess water to evaporate and the soap to become milder and harder.
The advantages of the cold process method are:
You have complete control over the ingredients and the quality of your soap.
You can create a wide range of soap types and styles by varying the oils, additives, colors, and scents.
You can make a long-lasting bar of soap that has a rich and creamy lather.
The disadvantages of the cold process method are:
You need to handle lye with care as it is a corrosive and dangerous substance that can cause burns, blindness, or even death if ingested or inhaled.
You need to measure the ingredients accurately and follow the instructions carefully to avoid mistakes or accidents.
You need to wait for a long time before you can use or sell your soap as it needs to cure properly.
You may encounter some problems such as trace, gel phase, soda ash, cracking, seizing, rancidity, etc. that can affect the appearance or performance of your soap.
Here are the steps to make cold process soap:
Gather your ingredients and equipment. You will need:
Oil or fat - 3 liters / 2.75 kg / 13 cups
Alkali - 370 g of caustic soda crystals made up as directed on the container, or lye solution made from plant ashes (see below)
Water - 1.2 liters / 5 cups
Additives - such as fragrances, colors, herbs, flowers, exfoliants, etc. (optional)
A large stainless steel or enamel pot
A heat-resistant glass or plastic container
A digital scale
A thermometer
A stick blender
A wooden spoon
A rubber spatula
A soap mold
A knife or cutter
A wire rack
Paper towels or newspapers
Protective gear - such as gloves, goggles, apron, mask, etc.
Prepare your work area. Make sure you have a clean, well-ventilated, and clutter-free space to work on. Cover your work surface with paper towels or newspapers to catch any spills or drips. Keep your ingredients and equipment within reach but away from children, pets, or food. Put on your protective gear and make sure you have some vinegar nearby to neutralize any lye spills.
Make your lye solution. If you are using caustic soda crystals, follow the instructions on the container to make your lye solution. If you are using plant ashes, follow these steps:
Slowly add 7.6 liters of water to 19 liters of ashes in a bucket with holes at the bottom. Place another bucket underneath to collect the brown lye water that will drip out after about an hour.
When no more lye drips out, put the lye water through the ashes again to increase its strength.
Test the strength of your lye water by floating an egg or a potato in it. If it sinks, the lye water is too weak and needs to be boiled down or run through more ashes. If it floats with a small part exposed, the lye water is ready to use. If it floats with a large part exposed, the lye water is too strong and needs to be diluted with more water.
Measure out 1.2 liters / 5 cups of your lye water and set it aside.
Note: Always add the lye to the water and not the other way around. Adding water to lye can cause a violent reaction that can splash or explode.
Melt your oil or fat. Measure out 3 liters / 2.75 kg / 13 cups of your oil or fat and put it in a large pot over low heat. Stir occasionally until it is completely melted and smooth. Turn off the heat and let it cool slightly.
Mix your oil and lye solution. Check the temperature of your oil and your lye solution with a thermometer. They should be around 100F / 38C. If they are too hot or too cold, you can either heat them up or cool them down by placing them in a hot or cold water bath. When they are at the right temperature, slowly pour your lye solution into your oil while stirring with a wooden spoon. Be careful not to splash or spill any of the mixture.
Blend your soap batter. Use a stick blender to blend your soap batter until it reaches trace. Trace is when the soap batter thickens and leaves a trail on the surface when you lift the blender. This can take anywhere from 5 to 30 minutes depending on your ingredients and equipment. You can check for trace by drizzling some soap batter on top of the rest of the batter. If it stays on the surface for a few seconds before sinking back in, you have reached trace.
Add your additives. If you want to add any fragrances, colors, herbs, flowers, exfoliants, or other additives to your soap, now is the time to do so. Stir them in gently with a wooden spoon or a spatula until they are well distributed throughout the soap batter. Be careful not to overmix or you may lose trace.
Pour your soap into a mold. Prepare your soap mold by lining it with parchment paper or plastic wrap. You can use any kind of mold that can withstand heat and hold its shape such as a wooden box, a plastic container, a silicone mold, or even a cardboard box. Pour your soap batter into your mold and tap it gently on the counter to remove any air bubbles. Smooth out the top with a spatula or a knife.
Insulate your soap. Cover your soap mold with a lid or another piece of cardboard and wrap it with a towel or a blanket. This will help keep the heat in and allow your soap to go through gel phase. Gel phase is when your soap heats up and becomes translucent and shiny. This can improve the color and texture of your soap, but it is not necessary for every recipe. If you want to avoid gel phase, you can either put your soap mold in the freezer or use a water discount (use less water than the recipe calls for).
Unmold and cut your soap. After 24 to 48 hours, you can unmold your soap and cut it into bars with a knife or a cutter. Be careful not to touch your soap with bare hands as it may still be caustic. Wear gloves and goggles for protection.
Cure your soap. Place your soap bars on a wire rack in a cool, dry, and well-ventilated area away from direct sunlight and humidity. Let them cure for four to six weeks, turning them over once a week to ensure even drying. Curing allows your soap to lose excess water, become harder and milder, and develop a better lather.
Section 2: The Melt and Pour Method
The melt and pour method is one of the easiest and fastest ways of making soap. It involves melting a pre-made base of glycerin soap that is ready to use as is or can be customized with various additives. The melted base is then poured into a mold and left to harden for a few hours or minutes. The soap is then unmolded and ready to use or sell.
The advantages of the melt and pour method are:
You don't need to handle lye or worry about measuring ingredients accurately.
You can make soap quickly and easily with minimal equipment and skills.
You can create a wide range of soap types and styles by using different bases, additives, colors, scents, molds, etc.
The disadvantages of the melt and pour method are:
You have less control over the ingredients and the quality of your soap base.
You may encounter some problems such as sweating, cloudiness, bubbles, cracking, etc. that can affect the appearance or performance of your soap.
Your soap may not last as long as cold process soap or may melt easily in hot weather or water.
Here are the steps to make melt and pour soap:
Gather your ingredients and equipment. You will need:
Soap base - 1 kg / 2.2 lbs of glycerin soap base (available in clear, white, or colored varieties)
Additives - such as fragrances, colors, herbs, flowers, exfoliants, etc. (optional)
A large microwave-safe bowl or a double boiler
A knife or a grater
A wooden spoon or a spatula
A soap mold
A spray bottle of rubbing alcohol
Paper towels or newspapers
Prepare your work area. Make sure you have a clean, well-ventilated, and clutter-free space to work on. Cover your work surface with paper towels or newspapers to catch any spills or drips. Keep your ingredients and equipment within reach but away from children, pets, or food.
Melt your soap base. Cut or grate your soap base into small pieces and put them in a large microwave-safe bowl or a double boiler. If using a microwave, heat the soap base in 30-second intervals, stirring after each one, until it is completely melted and smooth. If using a double boiler, heat the soap base over low to medium heat, stirring occasionally, until it is completely melted and smooth. Be careful not to overheat or boil your soap base as it may scorch or lose its clarity.
Add your additives. If you want to add any fragrances, colors, herbs, flowers, exfoliants, or other additives to your soap, now is the time to do so. Stir them in gently with a wooden spoon or a spatula until they are well distributed throughout the soap base. Be careful not to add too much as it may affect the quality or performance of your soap.
Pour your soap into a mold. Prepare your soap mold by spraying it with rubbing alcohol to prevent bubbles from forming on the surface of your soap. You can use any kind of mold that can withstand heat and hold its shape such as a plastic container, a silicone mold, or even a cookie cutter. Pour your soap base into your mold and tap it gently on the counter to remove any air bubbles. Smooth out the top with a spatula or a knife.
Spray your soap with rubbing alcohol. This will help prevent bubbles from forming on the surface of your soap and give it a smooth and shiny finish.
Unmold and use your soap. After a few hours or minutes depending on the size and shape of your mold, you can unmold your soap and use it right away or sell it. Be careful not to touch your soap with bare hands as it may be hot or sticky. Wear gloves for protection.
Section 3: The Hot Process Method
The hot process method is similar to the cold process method but with one major difference: the soap batter is cooked over heat after reaching trace until it is fully saponified and ready to use. The cooked soap is then scooped into a mold and left to harden for a few hours or days. The soap is then cut into bars and ready to use or sell.
The advantages of the hot process method are:
You don't need to wait for a long time before you can use or sell your soap as it doesn't need to cure.
You can use any fragrance, color, or additive that may not survive in cold process without worrying about losing its scent or quality.
You can make a rustic-looking bar of soap that has a soft and creamy texture.
The disadvantages of the hot process method are:
You need to handle lye with care as it is a corrosive and dangerous substance that can cause burns, blindness, or even death if ingested or inhaled.
You need to measure the ingredients accurately and follow the instructions carefully to avoid mistakes or accidents.
You need to cook your soap batter over heat which can be time-consuming and messy.
You may encounter some problems such as separation, scorching, volcanoes, etc. that can affect the appearance or performance of your soap.
Here are the steps to make hot process soap:
Gather your ingredients and equipment. You will need:
Oil or fat - 3 liters / 2.75 kg / 13 cups
Alkali - 370 g of caustic soda crystals made up as directed on the container, or lye solution made from plant ashes (see above)
Water - 1.2 liters / 5 cups
Additives - such as fragrances, colors, herbs, flowers, exfoliants, etc. (optional)
A large stainless steel or enamel pot with a lid
A heat-resistant glass or plastic container
A digital scale
A thermometer
A stick blender
A wooden spoon
A rubber spatula
A soap mold
A knife or cutter
A wire rack
Paper towels or newspapers
Protective gear - such as gloves, goggles, apron, mask, etc.
Prepare your work area. Make sure you have a clean, well-ventilated, and clutter-free space to work on. Cover your work surface with paper towels or newspapers to catch any spills or drips. Keep your ingredients and equipment within reach but away from children, pets, or food. Put on your protective gear and make sure you have some vinegar nearby to neutralize any lye spills.
Make your lye solution. If you are using caustic soda crystals, follow the instructions on the container to make your lye solution. If you are using plant ashes, follow the steps above to make your lye water and measure out 1.2 liters / 5 cups of it.
Note: Always add the lye to the water and not the other way around. Adding water to lye can cause a violent reaction that can splash or explode.
Melt your oil or fat. Measure out 3 liters / 2.75 kg / 13 cups of your oil or fat and put it in a large pot over low heat. Stir occasionally until it is completely melted and smooth. Turn off the heat and let it cool slightly.
Mix your oil and lye solution. Check the temperature of your oil and your lye solution with a thermometer. They should be around 100F / 38C. If they are too hot or too cold, you can either heat them up or cool them down by placing them in a hot or cold water bath. When they are at the right temperature, slowly pour your lye solution into your oil while stirring with a wooden spoon. Be careful not to splash or spill any of the mixture.

This can take anywhere from 5 to 30 minutes depending on your ingredients and equipment. You can check for trace by drizzling some soap batter on top of the rest of the batter. If it stays on the surface for a few seconds before sinking back in, you have reached trace.
Cook your soap batter. Cover your pot with a lid and place it over low to medium heat. Stir occasionally to prevent scorching or separation. You will notice some changes in your soap batter as it cooks such as bubbling, expanding, changing color or texture, etc. This is normal and part of the saponification process. Cook your soap batter until it is fully saponified and ready to use. You can test this by doing one of these methods:
The zap test: Take a small amount of soap batter and let it cool slightly before touching it to your tongue. If it zaps you like a battery, it means there is still some lye left in it and you need to cook it longer. If it doesn't zap you but tastes like soap, it means it is done and ready to use.
The pH test: Take a small amount of soap batter and let it cool slightly before dipping a pH strip into it. If the pH is between 8 and 10, it means it is done and ready to use.
Note: The cooking time may vary depending on your ingredients and equipment but it usually takes between 1 to 3 hours.
Add your additives. If you want to add any fragrances, colors, herbs, flowers, exfoliants, or other additives to your soap, now is the time to do so. Stir them in gently with a wooden spoon or a spatula until they are well distributed throughout the soap batter. Be careful not to add too much as it may affect the quality or performance of your soap.
Scoop your soap into a mold. Prepare your soap mold by lining it with parchment paper or plastic wrap. You can use any kind of mold that can withstand heat and hold its shape such as a wooden box, a plastic container, a silicone mold, or even a cardboard box. Scoop your soap batter into your mold and tap it gently on the counter to remove any air bubbles. Smooth out the top with a spatula or a knife.
Unmold and cut your soap. After a few hours or days depending on the size and shape of your mold, you can unmold your soap and cut it into bars with a knife or a cutter. Be careful not to touch your soap with bare hands as it may still be hot or sticky. Wear gloves for protection.
Use or sell your soap. Your soap is ready to use or sell as soon as it is cut. You don't need to cure it as it is already fully saponified and mild. However, you can still let it dry for a few days to make it harder and longer-lasting.
Section 4: Soap Recipes and Variations
Now that you know how to make soap using three different methods, you can start experimenting with different recipes and variations to create your own unique and personalized soap. Here are some tips on how to choose the best ingredients for your soap and how to use various additives to enhance your soap.
How to choose the best oils and fats for your soap
The oils and fats you use for your soap will determine its properties such as hardness, lather, moisturizing, cleansing, etc. Different oils and fats have different fatty acid compositions that affect their saponification values (the amount of lye needed to turn them into soap) and their iodine values (the degree of unsaturation of their fatty acids). Generally, the higher the saponification value, the more lye is needed and the harder the soap will be. The higher the iodine value, the more unsaturated the fatty acids are and the softer and more moisturizing the soap will be.
The oils and fats used in soap making fall into three categories as shown in the table below:
