How to Make Soap

Homemade soap making is my number one passion, so if I have a day to do nothing, I’ll just make it all day.

People always ask me how to make soap, so today I show you how I do it!

Master Soap Maker for 20+ Years

In 1994 I came across a book on soap making and thought, “Well, gee, it can’t be too hard.” I remembered my great grandmother from Sweden had made it, and so had my mother when I was much younger.

So I gathered my ingredients and set forth to make soap.

The First Batch of Homemade Soap

The first batch turned out great, then the next, but the next after that was a dismal failure. So what did I do wrong? I wasn’t sure, so I decided to take a class. I contacted the local adult education center and found the instructor had left the area. Would I be interested in teaching? I got talked into it and started the following January. I taught people how to make soap for a total of 11 years in Minnesota.

When I came to North Carolina in 2004, I had to hunt around a bit to find a venue, but ended up at a local college in 2007 and have been there ever since. I now teach classes on how to make soap, along with several other natural products. I also sell my soaps and other products online, at local tailgate markets, and at the state fair each year.

Soap Making: The Basics

Soap making can be very simple or you can make it as complicated as you like.

First, the beauty of making your own is that you can make it with the ingredients that you choose and the fragrances that you like. And adjustments aren’t hard but do take some practice. Further, most homemade soap recipes use ounces or grams and ingredients must be weighed to get good results. But I’ve found a way to simplify the process by converting the ingredients to cups and portions of cups. Consequently, it’s much easier and you get the same results time after time.

Lye in Homemade Soap

The one thing in homemade soap you can’t substitute is lye. You should always use 100% sodium hydroxide, or lye in crystal form. Don’t substitute liquid lye or drain cleaners such as Drano. These may cause inaccurate measurements or have bits of metal in them. You don’t want either.

Lye is caustic. It can eat holes in fabric and cause burns on your skin. Always be extra careful when using lye. Use gloves and eye protection and a mask if desired. When you mix the lye with water, it will heat up and fume for about 30 seconds to a minute. It may cause a choking sensation in your throat. Don’t worry, it’s not permanent and will go away after a few minutes. Always add lye to the water (not water to lye), and start stirring right away. If allowed to clump on the bottom, it could heat up all at once and cause an explosion.

There is No Lye in Finished Soap

Even though lye is caustic and dangerous to work with, after it reacts with the oils in your soap (through a process called saponification), no lye will remain in the finished product.

The lye reacts with the oils, turning what starts out as a liquid into blocks of soap. When made properly, no lye remains in the finished product.[1]

(For more information, read our article: Can You Make Soap Without Lye?)

Homemade Soap Making Equipment

When learning how to make soap, remember to use equipment that will not be used for cooking. While you could clean everything really well, it’s best not to take a chance.

Stainless steel, tempered glass, and enamel are all good choices for mixing bowls. Don’t use copper or aluminum, they will react with the lye. Some plastics may melt, so don’t use plastic bowls.

For spoons, use styrene plastic or silicone. For molds, you can get soap molds at your local craft store or online here, or use silicone baking pans (like this). These are great because you can peel the mold right off. Other things you want to have are a pint and a quart canning jar, newspaper, a stainless steel thermometer that reads between 90° and 200° (find it here), an old towel, and any additions you want to add to the soap.

How to Make Soap: The Additives

There are as many variations of soap as there are colors in the rainbow. You can literally do almost anything. Here are the basics of additives:


All herbal material must be dried. Lavender is popular, as well as chamomile. I love lemongrass and oakmoss, though not together. Use about ¼ cup of dried plant material per batch of this size. (Find high quality dried herbs here.)

Essential Oils

Essential oils are from plants. They come from the roots, stems, flowers, or seeds. Fragrance oils can be blends of essential oils or they can be artificially produced. Be sure you know what you have. Most oils can be used at the rate of 15-20 drops or around a teaspoon per batch of this size. (Find 100% pure essential oils here.)


Natural colors are easy. Use cinnamon or cocoa powder for brown soap, powdered chlorophyll for green, turmeric for yellow, and beetroot for orange. However, sometimes things change colors, like magenta beet powder turning yellowish-orange. I would avoid food colors since they don’t hold up well in soap. Check out our article, 44 Ways to Color Homemade Soap Naturally, for even more ideas.

Other Items

This would include aloe vera gel, oatmeal, dry milk powder, clays, cornmeal, ground coffee, salt, and anything else you may want to use.

Step 1

  1. Cover your work area with newspaper. Put your gloves and other protective wear on. Measure your water into the quart canning jar. Have a spoon ready. Measure your lye, making sure you have exactly ¼ cup. Slowly pour the lye into the water, stirring as you go. Stand back while you stir to avoid the fumes. When the water starts to clear, you can allow it to sit while you move to the next step.

Step 2

  1. In the pint jar, add your three oils together. They should just make a pint. Heat in a microwave for about a minute, or place the jar of oils in a pan of water to heat. Check the temperature of your oils – it should be about 120° or so. Your lye should have come down by then to about 120°. Wait for both to cool somewhere between 95° and 105°This is critical for soap making. Too low and it’ll come together quickly, but be coarse and crumbly.

Step 3

  1. When both the lye and oils are at the right temperature, pour the oils into a mixing bowl. Slowly add the lye, stirring until it’s all mixed. Stir by hand for a full 5 minutes. It’s very important to get as much of the lye in contact with as much of the soap as possible. After about 5 minutes, you can keep stirring or you can use an immersion blender (like this). The soap mixture will lighten in color and become thick. When it looks like vanilla pudding it’s at “trace” and you’re good to go. (Watch this video to see what trace looks like.)

Step 4

  1. Add your herbs, essential oils or other additions at this point. Stir thoroughly to combine. Pour the mixture into mold(s) and cover with plastic wrap. Set in an old towel and wrap it up. This will keep the residual heat in and start the saponification process. Saponification is the process of the base ingredients becoming soap.

Step 5

  1. After 24 hours, check your soap. If it’s still warm or soft, allow it to sit another 12-24 hours. When it’s cold and firm, turn it out onto a piece of parchment paper or baking rack. If using a loaf pan as your mold, cut into bars at this point. Allow soap to cure for 4 weeks or so. Be sure to turn it over once a week to expose all the sides to air (which is not necessary if using a baking rack). For a DIY soap drying rack, I took an old potato chip rack and slid cardboard fabric bolts (from a fabric store) through the rungs.

Step 6

  1. When your soap is fully cured, wrap it in wax paper or keep it in an airtight container. Hand made soap creates its own glycerin, which is a humectant, pulling moisture from the air. It should be wrapped to keep it from attracting dust and debris with the moisture.

Recipe Video


When you’re done making soap, always clean your equipment that has been exposed to lye. You can neutralize the lye with white vinegar, then wash the equipment well as you normally would. For the rest of it, let it sit for several days. Why? Because when you first make soap, it’s all fat and lye. You’ll be washing forever and you could burn your hands on the residual lye. If you wait, it becomes soap and all it takes to clean it is a soak in hot water.

  1. Cynthia Hoelscher says

    I have been making soap for 4 years. LOVE IT!! One tip I have learned is to be very careful when buying fragrant oils that contain vanilla. Some of the disclosures will say ” some vanilla may cause discoloration”. And trust me, it does.

    My siblings and children love using my soaps. First they would ask for a few bars. Now they ask for a full batch ( my recipe makes about 18 bars per batch).

    What started out as a hobby is now a necessity but I still love making it!

    • Kelly says

      Hi, did you ever get a response to your question? I had the same issue. It molded fine but then all crumbled when I cut it. Not sure what went wrong.

      • Amy says

        It sounds like your oils and lye were too hot. Make sure they have cooled down to about 95 degrees before mixing.

  2. Radhika says

    Hi – I understanding the items you use here, you should never use for cooking. However, in Step 3 where its says to use the hand blender – at this point is it okay to use a blender that is also used for cooking?

    • Amy says

      A stick blender is used. Not a traditional hand blender. I would recommend that it only be used for soaping

  3. Grace Ford says

    I’m a beginner soap maker just for my own family’s use. I love your blog. A question…whether I decide to use milk cartons or silicone moulds or plastic containers what’s best to use as a liner/barrier? I’ve read everything from parchment paper to wax paper to Vaseline to olive oil. Sorry if this has been answered before… I’ve read lots of your followers comments but didn’t finish. You have quite an audience. Thanks and keep soaping!
    (I’m from Canada so for the long winter I’m going to give this soap making a go)


    your tutorial has inspired me to try this, I wondered how much whey/coffee/kelp powder I would add to the batch? and will it come out clear if I add nothing but just scent? sorry to be a pain but nothing here in the UK seems as helpful as your article. thank you Christine.

  5. Hillary waters says

    Hi I made your soap and it turned out great. I was wondering if I can use cocoa butter in place of any of the ingredients for a chocolate smell and if so which ingredient do I replace? Would the measurement remain the same?


  6. Peter says

    I note that in the recipe it speaks to mixing the solid lye with water. As regards the fumes made in this process; these should not be inhaled. Work in a well ventilated area. Lye is caustic and some of it will be in the fumes resulting when the lye is added to the water – they can burn the throat and they should certainly not be inhaled. I taught chemistry so have a background in his matter.

    • Debra Maslowski says

      That is correct Peter. The fuming only lasts 30 seconds to a minute, but the area should be well ventilated. I keep my face turned away then leave the room for a few minutes after it’s mixed. You can use a mask if you like.

      • Romina says

        Do you have any tips on how I can incorporate fennel leaves and rosemary from the back garden into your recipe? Should I infuse them into an oil, or infuse them into a tea, or chop and add straight in?

  7. MEENA SOOD says

    I think reading the method of making soap, has made my mind quite clear about the method of making soap, will try and let you know.

    • Debra Maslowski says

      Once you try it Meena, you’ll never go back to store bought. I have a lot of soap all over the house and I still make more! Just remember to use lye in pellet form, not flakes, measure correctly and have all your oils liquid when you measure. Those are the most important things.

  8. sarah says

    Hey Debra! I can’t wait to start making soap and move to a remote area of the world and just revel in the purity of making my own hygiene and beauty products. There is definitely something to being able to rely on yourself like that! Just need to wait for my kiddos to be a little older to start playing with lye!

    • Debra Maslowski says

      You are so right about that Sarah! I don’t buy much of anything anymore. I do still buy conditioner for my hair, but I’m working on that now. Maybe someday I’ll be totally self sufficient!

  9. Gabby says

    Thanks for the recipe! If I plan to add honey into the soap, do I need to compensate for the added liquid by removing some water?

    • Debra Maslowski says

      Honey is tricky, Gabby. I usually add a tablespoon or so at the trace, after I’ve warmed it a bit. I don’t cut the water at all since it’s only a tablespoon. But…if you add too much, the sugars will heat the soap too much in the first few hours and could cause volcanoing. Not sure if that’s a real word, but you get the picture. I’ve tried honey powder, and it seems to cut down on it some, but the soap turned dark and got even darker over time. And your soap can stay sticky since honey is a natural humectant.

  10. Shelagh says

    Enjoyed your soap making directions & comments. I also have experienced great and dismal batches of soap. Your article has encouraged me to jump into soap making again. Thank you! Can you share what olive oil you recommend? Extra-virgin? Pure?

    • Debra Maslowski says

      Hi Shelagh! I tend to use cheaper olive oils as I find they have more fat to them. Look at the nutritional label on the back of the bottle. It should have 14 grams of fat per serving. Any less, and the soap may not turn out right. You can use virgin or extra virgin if you like, but make sure it has enough fat. Also, make sure that the olive oil you’re looking at is 100% olive oil. There are many out there that aren’t. Buy a trusted brand!

  11. Nina says


    Thank you for this informative article. You’ve made the process really simple. I wanted to know how much the quantity of lie should be if it’s in powder/crystal form. I’m guessing the quantity you e mentioned here is that of liquid lye. TIA!

    • Debra Maslowski says

      Hi Nina! I always use bead form in the lye. If you use liquid or flake form, it won’t measure right. If you can’t get it in bead form, you’ll need to use a lye calculator like soapcalc.com or one of the many available online. Because this is a small amount of soap being made, even a small miscalculation can result in soap that doesn’t turn out.

  12. Kristen says

    Hi there, i am so exited about making this, but i just wanted to clarify. When you say 90-120 degrees, are you talking Celsius or Fahrenheit? Many thanks 🙂
