Various Methods of Soap Making

If you’re interested in understanding the basics of melt and pour soap, it’s essential to recognize how it contrasts with other soap-making methods. There are four primary categories:

Cold Process
Hot Process
Rebatch
Melt and Pour

Key Differences Between Soap Making Methods

Cold Process Soap

Cold process soap is the traditional and most labor-intensive method of soap making. It appeals to artisans who desire maximum control over the entire process. This method allows for personalized choices in oils, plant butters, and natural additives like fruit purees or milk. As the name suggests, this technique does not involve heat, and the resulting soap must cure for a minimum of 30 days before use. Because this method employs potentially hazardous hydroxide lye and requires precise measurements, it is generally best learned in a classroom setting. Consider the cold process if you’re serious about soap making, especially if you plan to sell your creations in the future.

Hot Process Soap

Similar to cold process soap, hot process also involves hydroxide lye, but the saponification process is accelerated by heat, which eliminates the lengthy curing time. This method typically requires only about 12 hours of curing before the soap is usable—a significant time saver compared to 30 days! However, the use of fresh ingredients is discouraged, as they can scorch and spoil during storage. The hot process results in a mixture that resembles mashed potatoes before curing, lending a rustic aesthetic but making it challenging to achieve intricate designs or layers. Embedding heavier ingredients is also not recommended due to the dense consistency.

Rebatch Soap

Rebatching soap is a fantastic way to rescue a failed cold process batch. Essentially, it combines aspects of both cold and hot processes. However, unless you’re already making soap from scratch, this method may not be of interest to you.

Melt and Pour Soap

Melt and pour soap offers numerous advantages over the aforementioned methods. The most significant benefit is that the hard work of creating the soap base is already done for you. This method is perfect for anyone looking to explore soap making without the hassle of dealing with chemicals or waiting weeks for the final product. Melt and pour soap bases come in a variety of formulations, available in both clear and opaque options. While this pre-made product doesn’t provide the same level of customization as cold process soap, you can select a soap base that best fits your needs. Clear bases often include glycerin, honey, aloe vera, and hemp, which are great for vegans. Opaque options typically feature shea butter, goat milk, donkey milk, and oats. You can find a limited selection at popular craft stores, and many favorites are available for easy online ordering.

Another advantage of melt and pour soap is its quick setting and hardening time, meaning there’s no curing period. If you’re looking for soap you can use soon after making, this is the ideal option. Technically, you could simply cut the melt and pour soap block into bars and use them as-is, but that would be rather plain. Though melt and pour soap doesn’t require curing, it’s unsuitable for adding fresh ingredients like cold process soap. However, there are numerous ways to customize your soap to make it unique. The thinner, more liquid consistency is not ideal for embedding heavier additives but is perfect for layering colors, marbling, and swirls. Like other soap types, melt and pour can scorch if overheated, making it thick and difficult to work with. Don’t worry—I’ll guide you through the safest melting methods. Cleanup is a breeze; just rinse your tools and containers when you’re done, and you’re ready for your next project! Best of all, the tools and supplies for this craft take up minimal space and are easy to store.

Essential Tools and Supplies for Melt and Pour Soap Making

One of the primary reasons I was drawn to melt and pour soap is that it requires no specialized tools. In fact, you can find nearly everything you need at dollar or thrift stores. It’s crucial to remember that any equipment used for soap making should never be used for food!

Let’s explore what you’ll need, including some handy options:

Block of melt and pour soap
Heat-proof glass measuring bowl
Measuring cups and spoons
Small silicone spatula or large wooden popsicle sticks
Large kitchen knife
Optional: large rimmed cookie sheet
Silicone soap molds or loaf soap mold
Essential and/or fragrance oils (safe for soap making) – check out my Guide to Buying Essential Oils
Colorants: natural options like fine fruit or vegetable powders, activated charcoal, cocoa powder; synthetic colors specifically made for soap making; cosmetic-grade mica powders (for color and shimmer)
Other mix-ins such as finely ground herbs, dried lavender buds, ground oats, and pumice
Small plastic cups for mixing colors
Glycerin and/or 99% rubbing alcohol for mixing colors
99% rubbing alcohol in a small spray bottle
A heat source like a microwave or double boiler on the stovetop
Well-lit, protected work surface
Apron or old shirt to protect your clothing while you work
Plastic wrap or parchment paper for wrapping your finished soap

Many of these tools are a one-time investment, while items like colorants and essential oils can last quite a while! Note: 99% rubbing alcohol evaporates much faster and is the best choice for soap making; 91% can also work in a pinch, while 70% has too high a water content and is better suited for hand sanitizer spray.

Key Considerations Before You Start Making Melt and Pour Soap

Even though this project is straightforward for beginners, there are several important things to keep in mind before you begin. When I created my first batches using melt and pour soap, they turned out reasonably well; they performed their function, but they weren’t something I would have felt proud to share. I want you to achieve better results from the start.

Work with Manageable Batches

While it might be tempting to cut and melt an entire 5 lb block of soap at once, resist that urge! The beauty of melt and pour is that you can easily cut off a portion and save the rest for later. Just wrap the leftover block tightly in plastic wrap. Working with smaller batches gives you much greater control. Not sure how much liquid soap you’ll need for your molds? There’s a simple, low-tech method to determine the volume: fill one of the mold cavities with water, drain it into a measuring cup, and multiply by the number of cavities in your mold. Most of my molds hold about 4 oz of soap, which is a standard size. The goal is to create a soap bar that lasts a while—not too small, or it will be used up quickly, and not too large, or it may be difficult to hold.

Use Proper Amounts of Add-ins

Figuring out the right amounts can be tricky, but there are basic guidelines to ensure your finished soaps are successful. As a rule of thumb, never exceed 1 tablespoon of oils or other liquids per pound (16 oz) of soap, as more will result in excess liquid oozing from the soap. Mix colors and other additives before incorporating them into the soap liquid, adding a little at a time until you achieve the desired effect. Remember, when working with mica powder, a little goes a long way!

The Process of Making Soap with Melt and Pour Formulas

Creating soap with melt and pour is not a complicated process. It’s something you can even do with older children, but be sure to supervise closely, especially when working with hot soap. Preparing everything ahead of time will make the entire process run much more smoothly, trust me! It’s all about working smarter, not harder! Be sure to read this post thoroughly to understand the full process before diving in. My favorite tips and tricks are at the bottom.

Setting Up

Good preparation is vital for a smooth soap-making experience and easy cleanup. Begin by gathering all the necessary tools and materials from the list above. Cover your work area with thick craft paper or several layers of newspaper. Working near your heat source is essential, so using a kitchen counter is usually ideal. My favorite tip is to place a rimmed cookie sheet under the soap molds; line it with parchment paper or aluminum foil to catch any drips! Even though melt and pour soap hardens quickly, you may need to move the molds before the soap is fully set. Using a rigid cookie sheet allows for easy movement even when the soap isn’t completely hardened. If your soap contains any additives, ensure everything is ready and easily accessible before melting the soap base. This includes mixing colors, preparing herbs, and measuring fragrance oils.

Decide how many soaps you plan to create, and measure your ingredients accordingly. More detailed suggestions about ingredient amounts will follow.

Melting the Soap

Melt and pour soap is easy to cut into manageable chunks. For even and efficient melting, work with smaller batches—around 1 to 1.5 lbs at a time is ideal. Remember, you can always add more if needed. Melting can be done in a heat-proof bowl in the microwave. Most manufacturers recommend starting with 30 seconds, then continuing in 10- to 15-second intervals. Be sure to stir well after each round in the microwave. You’ll find it surprisingly quick to melt the soap. Alternatively, you can gently heat the soap in a double boiler. The melting temperature for melt and pour soap is relatively low, around 120 – 125 degrees Fahrenheit (approximately 50 degrees Celsius). If overheated, the soap can scorch, causing it to seize and become hard to work with, as well as discolor. Exercise caution when handling the hot soap container. I recommend using a large measuring bowl with a handle to avoid holding the rim with oven mitts. Once the soap is entirely melted, you can proceed to the next step.

Pouring the Liquid Soap

In its melted state, melt and pour soap resembles thick cream. Now is the perfect time to add colors, other additives, and essential or fragrance oils. Adding oils while the soap is still too hot can cause their scent to dissipate. You can introduce essential oils (around 3-5 drops per 4 oz bar) as soon as the soap is poured, but be sure to stir them in thoroughly. Consider how this will affect your soap if you’re using layers or creating a marbling effect.

Finishing Your Melt and Pour Soaps

After pouring, all that’s left is to wait for your soap to harden completely. This usually takes around 2 hours, depending on the room temperature. You can speed up the process by placing the molds in the refrigerator after the soap has set for about 30 minutes. This is where the tray tip comes in handy! If you have more soaps to create, simply repeat the process. If not, it’s time to clean up!

Storing and Using Your Finished Melt and Pour Soap

When stored correctly, finished melt and pour soap can last for a long time. We’ve used soap bars that were a year old, and they were perfectly fine. I hope you’ll store yours in a way that makes them easy to find! As a glycerin-based product, all melt and pour soap will “sweat” to some degree. Wrap your soap tightly in plastic wrap or parchment paper (my preferred method) and store it in a cool, dry location. To use your soap in the shower or bath, create a nice lather with a shower pouf. If you’ve avoided bar soap due to a preference for body wash lather, rest assured that it performs just as well! While it’s your choice, we prefer not to use bar soap for hand washing in shared spaces; liquid soap is the better option for keeping germs at bay.

Allow your soap bars to dry thoroughly between uses by keeping them on a soap holder that promotes airflow around all sides. Look for designs that can be easily disassembled for cleaning.

Additional Tips and Troubleshooting Common Melt and Pour Soap Issues

Bubbles on Top of the Soap

While bubbles don’t impact the soap’s effectiveness, they can be visually unappealing. To prevent this, ensure that your soap is at the correct temperature when pouring. To eliminate bubbles, give the freshly poured soap a quick spray with 99% rubbing alcohol.

Color Not Dispersing Well or Fading

To achieve even color distribution in your finished soap, mix your coloring agent (whether synthetic or natural) thoroughly with a small amount of glycerin or 99% rubbing alcohol. Ensure there are no lumps in the color mixture. Add this to your liquid soap and stir well until fully incorporated. While consistent color is often desired, streaks and marbling can also create stunning effects! To prevent colors from fading or bleeding, only use synthetic colors designed for soap making. Natural colors can be more muted, so consider this when selecting your coloring products. Avoid using food coloring, as it may stain and tends to blend together and fade.

Clear Soap Turns Cloudy

If you’ve chosen a clear soap base for its transparency, it can be frustrating when it turns cloudy. Unfortunately, once it becomes opaque, you cannot revert it to its original clear state. The most common cause of cloudiness is excessive stirring, which introduces tiny air bubbles that remain suspended in the soap. Too much heat can also cloud clear soap, so always opt for lower, gentler heating methods.

Finished Soap is Sweating

A small amount of sweating is normal for melt and pour soap. As a product that is nearly finished before you start working with it, it can only hold a certain amount of additional volume. Once it reaches saturation, it can’t absorb any more water. For optimal results, never add more than 1 tablespoon of additional oils or liquids per pound of soap. The general guideline for essential oils and fragrance oils is to use about 3% per pound, equating to approximately 0.48 oz.

Added Ingredients Won’t Disperse Evenly

The thinner liquid consistency of melt and pour soap makes it fun for creating layers, swirls, and marbling, but it also allows heavier ingredients to sink to the bottom of the mold. To counteract this, mix some of the heavier ingredients thoroughly before pouring. You can also create layered pours using the same mixture. There are specialized suspension soap bases available that are formulated to hold larger particles in place.

Pro Tips

Purchase a clear glycerin soap base and add white titanium dioxide pigment to achieve a more opaque appearance.
Lightly spray intricate soap molds with 99% isopropyl alcohol to ensure a clean release of the soap.
Utilize Vanilla Color Stabilizer to prevent discoloration when using vanilla fragrance oil.
Always use high-quality essential and fragrance oils, as low-cost options may not be pure and could contain unwanted chemicals.
