How to Make Soap at Home

My experimentations with do-it-yourself soap began once I began to get soft on with creating things reception the long way: creating and maintaining my very own sourdough starter, painting my very own room cupboards, and repairing my very own garments. although long, I found that doing things myself, from beginning to completion, was vastly profitable. It gave Maine a way bigger appreciation for the products that came to my manner and created Maine plenty of additional awareness (in a decent way) of the standard of ingredients.

As time slid and my life got busier, my hobbies started absorbing less of it. However, somehow, soapmaking stuck around. though it will appear terribly difficult initially, and thus off-putting to some, I’ve truly found it’s one amongst the simplest effort-to-reward ratios of all the “pioneer crafts” I’ve tried. very like knitting, it’s a pondering activity and an inventive outlet—but in contrast to knitting, simply some evenings or weekends of labor reap nice rewards, furthermore as furnish Maine with numerous readymade gifts for the folks i like.

With just a few tools (many of that area unit recent friends within the kitchen), associate degreed armed with an understanding of however it all comes along, do-it-yourself soap extremely does not feel that {much additional|far more|rather more|way more} bold than a number of the more adventuresome baking comes I’ve started over the years—and the results area unit well worthwhile (and fill your home with delicious scents, very like freshly baked goodies). Once you’ve got a base direction down, you’ll be able to additionally play with shapes, colors, scents, and additives to customize every batch, and build them your own.

What you’ll need:


16 ounces oil

14 ounces vegetable oil, ideally from an accountable supply (alternatives to vegetable oil are often found here.)

21 ounces oil, the most cost-effective you’ll be able to notice

19 ounces water

sodium hydroxide (lye), a pair of pound instrumentality of which is able to build concerning four batches of soap

7 teaspoons volatile oil or fragrance oil (optional)


Large heat-safe vessel like associate degree cooking utensil soup pot*

Measuring cup or little bowl*

Heat-safe vessel, ideally with a handle, like an important glass pitcher*

Silicone spatula or different stirring utensil*

Instant-read thermometer*

Immersion blender*

Scale that may live in grams and ounces

Soap mold or a 9-inch by 12-inch baking pan*

Plastic wrap (if employing a baking pan)

Waxed paper or parchment paper

Teaspoon and extra cup (if victimization fragrance)

Old towel or blanket

Sharp, thin knife

Rubber gloves

Safety eyeglasses

*Any tools that bit caustic mustn’t be reused for cooking!

Notes on safety, lye, and sourcing tools:
Although the method of creating soap is by and enormous easy and safe, it’s necessary to follow caution throughout the method that involves handling caustic. caustic may be a caustic salt (also refered to as Na hydroxide) that principally comes in crystalline kind and if handled incorrectly will burn skin and eyes. to shield yourself, bear in mind to invariably wear gloves, eye protection, and long sleeves, and add a well-ventilated space. Keep your face aloof from the caustic as you combine it, and keep pets and kids aloof from it as it’s cooling. however don’t worry concerning your soap being unsafe—all the caustic are going to be spent within the reaction method (the reaction between caustic and fat that produces soap and renders the caustic safe to handle) and none can stay within the finished product.

If you are in the least involved concerning operating with caustic, a simple thanks to guarantee none remains in your finished soap is to use a bit additional fat than the number that will specifically be off out by the reaction method. this is often known as “superfatting,” and can nearly undoubtedly be coated in any calculator, chart, or alternative resource used for developing soap recipes.

For soapmaking, i like to recommend buying caustic marked as “pure” or “food-grade,” and buy it on-line instead of in stores. i do not advocate shopping for caustic that is specifically marketed as a drain opener (its alternative primary use) for this method as a result of it’d produce other ingredients similarly. It comes in numerous forms, very {little} beads or little flakes; it does not matter that you select for this method. (Interestingly, caustic is additionally utilized in some recipes. I’ve haven’t done it nonetheless, however i have been desperate to strive creating these Bavarian-style soft pretzels.)

Although soapmaking becomes efficient if you are doing it usually, creating your 1st batch will seem to be a touch of AN investment since none of the tools may be reused for preparation (a sensible reason to create soap once more and again). I’ve coupled on top of to cheap choices for several of the tools needed, and thrift stores are a good possibility for things just like the pitcher and pot. Oils for soapmaking may be purchased in 7-pound baggage, which is able to keep prices down quite bit if you make over one batch.

How to create soap at home:

1. combine the caustic. placed on your rubber gloves and safety spectacles, ANd established during a} very well-ventilated space like next to an open window. If you’ve got access to the outside, take this step there. Use your scale and cup to rigorously weigh 201 grams of caustic soda and set it aside. Then, weigh nineteen ounces of water into your glass pitcher or alternative durable, heat-safe vessel. Now, rigorously pour the caustic soda into the pitcher of water, and stir simply long enough to create certain it all dissolves. This creates a chemical change that heats the water to over 200° F and produces robust fumes initially, thus work quickly and be additional careful here—I attempt to hold my breath whereas I stir. (Safety note: invariably add this order and add caustic to water. ne’er add water to caustic, which may cause spattering of the new caustic resolution or maybe AN explosion.)

The caustic currently has to cool to below 100° F. I sometimes place mine outside on my construction to hurry up this method. betting on however cold it’s out, it will take between thirty and ninety minutes for the caustic to chill, that is why i like to recommend obtaining this get out of the means 1st.

2. Prepare the mould and measure fragrance. If you are employing a picket loaf mould or a baking pan, rigorously line the within with waxed paper or parchment paper thus its easier to urge the soap out later. I usually use some masking paper to assist hold everything in situ. If you employ a silicone polymer mould, you’ll skip this step.

If you like the simplicity of plain rectangular soap bars and think you’ll make more than a couple batches of soap, having a wooden loaf mold like the one shown here makes the process easy and consistent. (I’ve found eBay and Etsy to be good sources for wooden versions at lower prices.) Other options include silicone and PVC plastic molds, which come in many shapes and patterns. If you’re not ready to invest yet, a 9 by 12-inch baking pan or Pyrex dish that have seen better days and that your kitchen is willing to part with should also work just fine for this recipe.

Now is also a good time to measure out your essential oils into an extra measuring cup, for ease of adding them later. Blending fragrances is probably one of the most fun parts of making soap. For this batch, I used 5 teaspoons of orange essential oil and 2 of sandalwood. Synthetic fragrance oils also work well and are generally less expensive than pure essential oils. Mixing fragrances is akin to mixing spices and other ingredients when experimenting with cooking a dish—here is a great set of tips for having fun with blending fragrance oils. You can also opt to make unscented soap (if you’re very sensitive to scents and perfumes) and simply leave this ingredient out.

3. Melt and mix the oils. You can now prepare the blend of oils to which you’ll add the lye. If you’re using oils that are solid at room temperature, such as the coconut and palm oils in this recipe, you’ll first need to melt them so they can be poured, either by placing the container in a saucepan of simmering water or by melting them in the microwave.

Once your oils are in a liquid state, place your large pot on the scale and weigh (or re-weigh, if you’ve already done so) each oil into it for precision. Stir everything together and then check the temperature with a heat-safe thermometer. For the next step, the oils need to be between 80 and 100° F. I often find that mine are already in the correct range from being melted, but if not, place the pot on the stove over low heat until the oils reach the proper temperature or set aside to cool down.

4. Blend and pour your soap. 
When both your lye and your oil mixture are between 80 and 100° F, you’re ready to blend. After removing the pot from the heat to a trivet or heat-safe surface, put your gloves and eye protection back on and carefully pour the lye into the pot of oil. They’ll begin to react with each other, turning the mixture cloudy. Begin blending with your immersion blender, and over the next 3 to 5 minutes you’ll see the mixture become thicker and more opaque. You’re aiming for a mixture with the consistency of a runny pudding. If you lift the blender out and let some drips fall across the surface of the mixture, you should see them leave a visible pattern, called “trace,” before sinking back in.

Once the soap mixture has reached trace, stir in the fragrance oil, if using, until blended. Carefully pour the finished mixture into your lined soap mold, and cover with the lid (or plastic wrap, if your mold has no lid). Being sure to keep it level, wrap the whole thing in a towel or blanket to insulate it, and leave undisturbed in an airy out-of-the-way place like a shelf for 24 hours.

This method that I use for making soap is called cold process, where no additional heat is used to facilitate or speed up the saponification process. Hot process, on the other hand, uses an external heat source to accelerate it. While cold process soaps take longer to cure (the next stage, below), the choice to use one or the other isentirely personal.

5. Cut and cure your soap. When your clock indicates that 24 hours is done (don’t try and rush it), your soap is ready to be removed; many wooden loaf molds have fold-down sides or removable bottoms to make this process easier. If you’ve used a baking pan, you may need to use a knife to help pry the soap loaf out. Cut the loaf into bars with a sharp knife.

Naturally, you don’t want your soaps to crumble when you cut them—and soapmakers have all sorts of ideas on which tools to use to cut soap with. Some use guitar strings, others use butcher’s knives. Still others opt for specialty tools like this (and this). Some DIY-ers even fashion their own instruments. I use a ruler and score the top of the loaf with a sharp knife before cutting to make sure everything stays straight and even. I like generous bars, so I cut them about an inch thick.

Your work is now done, but the bars need to cure for 4 to 6 weeks (remember what I said about patience?) before being used. This time allows the water in the bars to fully evaporate, resulting in a harder and milder soap. Leave the soap to cure on a paper bag or baking rack in the same airy location. If you use a paper bag, turn the bars once or twice during the curing time to make sure all sides are equally exposed to air.

Cleaning up:

The pitcher, measuring cup, and spatula just need to be thoroughly rinsed with water. For the pot with raw soap residue in it, I usually wipe it out first with paper towels before washing it with dish soap and water. Use any tools that touched the lye only for soapmaking, and store them away from the kitchen, ideally on a shelf separate from other kitchen tools in common use, to prevent any chance of confusion.

Creating your own recipes:

This recipe is only one of practically endless combinations and ratios of fats, lye, and other ingredients that you can use to make soap. A lot of the fun of soapmaking is in exploring new recipes and seeing what turns out. Some of my favorite combinations have been orange and sandalwood with poppy seeds, lavender and clary sage with dried lavender blossoms, and rosemary and cedar wood with dried thyme.

You can also change the ratios and types of fat to make soaps with different properties, as well as using liquids other than water (such as milk). Online oil charts and lye calculators can help you finish your recipe. The proportions for this particular recipe are taken from Susan Miller Cavitch’s The Soapmaker’s Companion, a good all-around resource for learning about the science of soapmaking, exploring options for ingredients and techniques, and troubleshooting problems.

Congratulations, you’re a soapmaker! Now get creative and have fun—but please be safe.
