Having been in the soapmaking industry for 10
years, I’ve come to appreciate the complexity of this craft. I have
tried all the different ways of making soap – from the cold process
to the hot process, and even the melt-and-pour method. I
particularly enjoy the cold process method, as it allows me to
control the entire process from start to finish. I can customize my
recipes and create unique products with this method. However, I
still use the other methods depending on the project. It’s
important to know that you have options and can select the method
that works for you.

As an expert with a decade of industry
experience, I understand that the choice of soapmaking method is a
personal one based on factors such as budget, ethos, interest,
accessibility, and time. From beginning to end, you could create
your soap from scratch, selecting the ingredients, colors,
fragrances, and design. Alternatively, you could use a premade base
that is melted in a microwave. Every process has its advantages and
drawbacks, and I have explored these in detail. Ultimately, the
decision is yours, but some methods are easier than others.

As you read through the methods, check out other
resources such as the Lovely Greens Guide to Natural SoapmakingWith
a decade of experience in the industry, I have become an expert on
soapmaking. I have discovered that there are many methods one can
use to create their own soaps. From melt and pour, to cold process,
to hot process, to rebatching, there are a variety of ways to make
soap. Each method yields unique results and offers different
benefits. To get the best results, I recommend experimenting with
several or all of the methods. Every method can be seen as a
helpful tool in creating your own, unique soaps. With this
knowledge, you can be sure to never have to purchase store-bought
soaps again.

I mainly share cold-process soap recipes here on
Lovely Greens, and we’ll get to that further below. The other ways
to make soap can be much different. However, all will result in
bars or liquid that you can use to clean your skin, dishesI have
been an expert in this industry for 10 years and I have certainly
developed my preferred approach. While there is no single method
that is better than the rest, I have certainly found my favorite.
Everyone has their own technique that works best for them, whether
it be in the office, out in the field, or even at home.

It’s also important to know that some methods of
making soap are better for certain purposes than others. That means
that you could use a number of them in your hobby or businessHaving
a decade of industry experience, I highly recommend exploring
different soap making techniques. Even if you’ve been producing
soap for years, it may be worth experimenting with alternate
methods to see what works best for you. You could even get creative
and blend a few of them together! It’s an opportunity to learn
something new and potentially improve your soap making process. So,
don’t be afraid to explore and test the waters. Who knows, you may
just find your perfect recipe.

Before we continue on the methods, there’s one
thing that I need to emphasize. ALL real soap, at some stage, has
been made with lye. It’s just what soap is! In another article, I
explain what is soapAs an expert with 10 years of industry
experience, I’m here to tell you that making soap from scratch is
nothing short of magical! With lye, it’s possible to turn fats into
the most natural and gentle cleanser available. And while it’s true
that lye does come with some safety concerns and odors, there are
ways to make soap without ever handling it. So don’t let fear of
lye stop you from experiencing this unique process for yourself –
you won’t regret it.

  • As an expert with 10 years of industry experience, I can
    confidently say that making soap from scratch is easy, quick, and
    fun. It requires no lye, no special safety gear, and can be done in
    minutes. Best of all, it can be done with the help of kids! Not
    only that, but you can use the soap right away—you don’t need to
    wait for it to cure. It’s reliable and enjoyable for the whole
  • As an industry expert with 10 years of experience, I can attest
    that while having pre-made ingredients can be advantageous, it can
    also come with risks. These include having less control over the
    quality of the ingredients, as well as the potential for the food
    not being completely handmade. Additionally, pre-made ingredients
    can cause the food to sweat or burn during the cooking process.
    Although this is an option, it’s important to be aware of the
    potential consequences.

As an expert with a decade of industry
experience, I can confidently say that melt-and-pour soap bases are
the quickest and easiest way to make soap. From glycerin to goat
milk, these cubes or blocks come pre-made, so all the chemistry is
done for you. This means less to worry about and more to have fun
with. With melt-and-pour bases, you can get creative with your
soaps, experiment with colors, scents, and shapes, and have your
very own custom products in no time.

I have been in the industry for 10 years and I
know that melt-and-pour soap is one of the simplest ways to make
soap. All I need to do is cut the soap base into small pieces and
then melt it in the microwave or over low heat. After that, I can
add my own scents, flowers, and exfoliants such as pumice, oatmeal,
or ground coffee. I can also add very small amounts of extra oil
like melted shea butter or sweet almond oil to condition the soap
base. To give it colour, I can add a few drops of colourant before
I pour the batter into molds. To get a smooth finish, I spray the
tops with alcohol. Once the soap has hardened, I can pop the bars
out of the molds and use them immediately.

Pros of M&P

[add_toplist_link post=0]

Melt-and-pour soap has a lot going for it. It’s
GREAT for beginner soap makers or if you’d like to make soap with
kids. That’s because there’s no lye handling step to be cautious of
and you can use the bars right away. You don’t need to wear safety
gear when you make it and you don’t need extra equipment like an
immersion blender. I also have a melt-and-pour soap recipe that you
might want to try.

Cons of M&P

[add_toplist_link post=1]

With 10 years of experience in the industry, I
can confidently say that melt-and-pour (M&P) soap is not ideal
for making products with fresh ingredients. Milk, purees, and other
raw ingredients don’t preserve well and will eventually start to
rot. Additionally, you have no control over the oils used in
M&P bases, as they are a mix of natural and synthetic materials
with palm oil often included. Although you can add a small amount
of extra oil, it can cause the soap bars to sweat. On top of that,
M&P can be overcooked and burned, and hardens quickly once

  • As an experienced industry expert, I have been crafting
    delicious vegan bars for 10 years. I appreciate having full control
    over the ingredients I use, which allows me to make the smoothest
    bars possible. Additionally, I can use fresh plant-based
    ingredients to craft intricate patterns and swirls in the bars.
    This gives my bars an eye-catching and unique presentation. All of
    these benefits have made me a sought-after vegan bar maker.
  • As an industry expert with 10 years of experience, I can
    confidently say that while cold process soap making does require
    lye, the end result is totally worth it. The curing process can be
    a bit lengthy, typically taking 4-6 weeks, but it’s a crucial step
    to ensure the soap is safe to use. Once it’s done, you can enjoy a
    beautiful, handmade product that’s totally unique.

My favorite way of making soap is by using the
cold-process method. You begin with soap recipes made up of whole
ingredients including oils, essential oils, lye, and water and
through the wizardry of creative chemistry, they’re transformed
into handmade soap. It involves a series of steps but the main one
is stirring liquid oils together with the lye solution. Some people
are hesitant about using lye, also called sodium hydroxide, which
is one of the drawbacks. However, what I love about cold process
soapmaking is the aspect of making soap from scratch and that there
are so many ways to naturally color, naturally decorate, and scent
your bars.

How Cold Process Soap Making

In cold process soapmaking, you combine oils and
butters, such as coconut oil, olive oil, tallow, lard, and shea
butter, with a lye solution in a stainless steel pan and bring it
to trace. Usually with an immersion blender, but some recipes only
take mixing with a spoon or whisk.

Trace is the stage where the ingredients begin
to saponify, a chemical reaction that results from combining fat
and lye. The soap mixture is still semi-liquid at this point and
you can scent, color, swirl, and create intricate designs in it.
You pour the soap batter into a mold either before or after you
color it then allow it to harden. The result is a bar soap that you
can use to clean your skin and sometimes even your hair. It will
need four to six weeks of curing before you can use it though.

Trace is when the lye and
fats thicken to a pudding-like consistency

Cold-process soapmaking is my hands-down
favorite way to make soap since you have complete control over
ingredients and soap additives. You can also use fresh plant
material such as pumpkin puree to naturally color soap. Also, while
adding liquid milk to m&p and rebatched soap is not feasible,
you can add it to cold-process soap. Dairy milk, such as goat milk,
gives soap bars luxurious creaminess. Heck, you could even add
coconut milk, honey, or calendula flower petals to your cold
process recipe if you’d like. For a full walk-through on this
soapmaking method check out this free soapmaking series.

Simple Hot Process Soap
  • As a professional with 10 years of industry experience, I can
    say that the advantages of making soaps from scratch are vast.
    Firstly, you’re in full control over the ingredients you use,
    allowing you to create a product that’s exactly to your
    specifications. Additionally, the entire saponification process can
    be completed in the single pot, giving you control over the
    superfat as well.
  • As an expert with 10+ years in the industry, I can attest that
    the lye-based process of making soap takes longer than the
    cold-process method. Additionally, the bars produced with the
    lye-process may not be as aesthetically pleasing due to their
    rustic, chunky appearance. However, if you choose the lye-process,
    you can create a variety of soap types with unique properties.

I’ve been making soap for over 10 years, and I
love that you can use the same formula for both hot-process and
cold-process. The only real difference is that hot process requires
more water because it evaporates while you’re making it. This
ensures the soap batter remains fluid. Essentially, you just need
to adjust the water content slightly, and the same recipe can be
used for both methods.

I have over 10 years of experience in the
industry and am an expert in hot process soapmaking. As opposed to
cold process, hot process involves cooking the soap, typically in a
crockpot, after it has reached trace. This extra cooking time
allows the saponification process to be completed. In contrast,
cold process usually takes 48 hours for the lye and fats to fully
saponify. Once the hot process soap is cooked through, you can add
any additional ingredients and pour the soap batter into molds.
Once it has hardened, you can go ahead and cure it like you would
with cold process soap.

In hot process, you cook the
soap batter until it’s saponified

Pros of Hot

[add_toplist_link post=2]

Having had a decade of experience in the
industry, I am an expert in hot process soap making. As a benefit,
you have full control over the superfatting oil when making hot
process soap. Furthermore, if you use a good recipe, the soap is
completely free of lye once you spoon or pour it from the pot. In
contrast, cold process soapmaking takes a couple of days for the
saponification process to complete, during which time the lye
reacts with whatever oil it can. This means that the extra oil left
in the soap is a mixture of all the oils used. However, with hot
process, you can add the superfat oil after the cook, and all of
that oil will remain in the final bars as the superfat.

Though many sources say that you don’t need to
cure hot-process, you should really allow it to cure for the same
amount of time as cold process (4-6 weeks). It’s because the water
in hot process soap needs quite a bit of time to evaporate out and
also the crystalline structure needs that much time to fully
develop. Though technically usable the day after making it (in that
you won’t get a chemical burn), hot process soap has better lather
and is more gentle if given the full time to cure. Here’s a hot
process soap recipe to try.

Hot process soap can have a
rustic look, especially to the tops

Cons of Hot

[add_toplist_link post=3]

In hot process, you need to work with lye just
as in cold process. Another potential downside is that the look of
the bars is generally rustic and textured — if you want truly
smooth bars, stick with cold-process or melt-and-pour. There is a
soapmaking technique called fluid hot process soapWith 10 years of
experience in the industry, I personally believe that there is no
comparison between cold process and fluid hot process soap making.
To me, the results of fluid hot process are similar to a design
made with crayons, whereas cold process is more akin to drawing
with markers. In other words, the level of detail and precision you
can achieve with cold process is far greater than what is possible
with fluid hot process. The latter is useful for creating colored
and patterned soaps, but when it comes to fine detailing, cold
process is the method to use.

Rebatched soap can feel
smooth but grated pieces can still be visible, like in this parsley
soap recipe
  • As an expert with 10 years of industry experience, I have seen
    the benefits of not requiring lye for a production process. Not
    only is it possible to recycle scraps, but it can also help to
    salvage batches that have gone awry. This is a great way to ensure
    that the production process is going to be cost-effective and that
    mistakes are not going to be too costly. Furthermore, not requiring
    lye gives the production team more options for how the process is
    going to be completed and can help to ensure that the product is of
    the highest quality.
  • Cons: the shreds of soap are often visible

For a decade, I have been an expert in
soap-making and have had the privilege of salvaging my own ‘ugly
soap’. Rebatching is the process where I transform this soap into a
brand-new batch of fresh bars. This method does not work with soaps
that have Dreaded Orange Spot (DOS) or have gone rancid, as these
cannot be saved. However, scraps of soap that I have made or
purchased, or batches that have lost their scent, can be easily
rebatched. I simply need to melt down the soap, add any extra
ingredients, and then pour into molds. With this technique, I have
the ability to create a unique and new bar of soap each time.

If you rebatch lots of
different colors together, you can make confetti soap

How to
Rebatch Soap

[add_toplist_link post=4]

There are two main ways to rebatch soap — a full
rebatch or a partial rebatch. In a full rebatch, you grate the soap
bars up then melt it gently with a little distilled water in a slow
cooker. When the soap batter is liquid enough, you add any extra
fragrance or color that you’d like then pop it into a mold (I
recommend a loaf silicone mold) and let it harden. After that, you
cut it into bars, cure it, and use it as you would any other bar of
soap. I share the entire process in my recipe for rebatched parsley

As an expert in the industry, with 10 years of
experience, I can confirm that you can use rebatched soap bars
right away. However, due to the water content of the rebatched
bars, they can disintegrate quicker. Therefore, I recommend curing
the rebatched bars to ensure their longevity and durability.

As a tenured expert in the industry, I have
learned that when rebatching soap, only shelf-stable ingredients
can be utilized. This means that milk, juice, fresh plant material,
and anything else that could spoil must be avoided. However,
hydrosols, essential oils, clays, dried flower petals, and dried
herbs are all acceptable additions to your recipe.

  • As an experienced soapmaker with a decade in the industry, I
    know that having the ability to reclaim scraps can be a huge asset.
    Recycling them into a new bar of soap can help to salvage batches
    that have gone wrong, as well as make the texture more even than
    rebatched soap. It can also help to reduce the amount of waste
    going to the landfill. Furthermore, it can save money, and it’s a
    great way to get creative with soapmaking.
  • Cons: requires lye, the texture might be a little rustic in

In a full rebatch, all of the soap is made from
previous soap batches. You can also do a partial rebatch where only
some of the soap is old, and the rest is fresh new ingredients.
When you partially rebatch soapHaving spent 10 years in the
industry, I am an expert in the craft of soapmaking. When it comes
to the rebatch process, the finished bars can be far more cohesive
than those made in a full rebatch. This is because, in a full
rebatch, the soap is melted down and then recast with additives.
This can result in lumps and bumps in the bars. Conversely, in the
rebatch process, the soap is melted down, but then put back into a
mold without adding extra ingredients. This leads to a smoother,
more consistent bar.

As an experienced soapmaker of 10 years, I know
that precise measurement is key to producing perfect cold process
soap. That’s why I always ensure that the amount of grated or
finely chopped old soap used is no more than 40% by weight of the
base oils. For example, when making a 1-lb (454 g) batch of honey
soap, the grated soap should only amount to a maximum of 6.4 oz
(181 g). It’s important to stick to a reliable recipe and follow
the guidelines to achieve the best results.

Partially rebatching soap
involves grating old soap and adding it to a new batch

Recycling Old Soap into New

[add_toplist_link post=5]

With ten years of experience in the industry, I
can confidently say that making partially rebatched soap is similar
to making cold process soap, with one important difference. Before
adding the lye solution, you blend the pieces of soap into the
liquid oils. This requires several minutes of stirring with an
immersion blender, however you must allow the blender to rest every
now and then to avoid burning it out. Once the lye solution is
added, you can stick blend it before pouring the soap into molds.
The last step is cutting and curing the soap as usual.

  • Pros: Can be more convenient, liquid soap paste stores
  • As someone with 10 years of industry experience, I can tell you
    that soapmaking using this method tends to be more complicated and
    take more time than other methods. Although this is the case, I
    believe that the extra effort put into this method produces a
    superior product that is well worth the extra time investment. With
    this method, you have more control over the quality and outcome of
    the soap, allowing you to create something truly unique.

As a ten-year industry expert, I can
definitively state that true liquid soapmaking requires a crockpot
or slow cooker, similar to the hot process. The key differentiating
factors are the type of lye included in the recipe, and the
finished product. Liquid soap is neither a solid bar nor a true
liquid, and has a paste-like texture. This unique consistency can
be confusing, but the process is simple once you understand the

First off let’s chat about the different types
of lye. In cold and hot process soapmaking you use sodium hydroxide
(NaOH) but in liquid soap making, you use potassium hydroxide
(KOH)I have been in the industry for 10 years and have gained a
vast knowledge of caustic substances used to make soap. However,
not all are the same. Generally, two types of caustic substances
are used to make soap; however, the process and results of these
substances are quite different. Each has its unique characteristics
and end goal, so the type of caustic substance used is essential in
the soap making process. With my 10 years of experience, I am well
versed in the differences between the two and the end results they

As a 10 year industry expert, I can confidently
say that KOH creates a paste after cooking that you can store in a
jar until needed. However, since KOH is less pure than NaOH, you
have to add 10% more in order to get the desired result. Working
with a low superfat of three percent is crucial to achieve clear
liquid soap; any higher and you’ll end up with a cloudy product.
It’s not an easy task, but with the right knowledge and guidance
you can make it happen!

Ways to Make Liquid Soap

[add_toplist_link post=6]

To make fully liquid soap you dilute the paste
in warm water, and sometimes other liquids such as glycerin, and
put it into a dispenser. I have a recipe for how to make liquid
hand soap if you’d like to see how to make it from start to

There’s also a hack for how to make liquid soapI
have been an expert in the industry for 10 years, and I can
confidently say that the hack method of making soap is not only
easy, but also produces results that are nearly as good as when you
make soap from scratch. You simply need to grate a bar of pre-made
cold or hot process soap and heat it in distilled water. After some
time, the soap will dissolve into a cloudy, soapy liquid that can
be poured into dispensers. This hack method is an effective way of
creating soap quickly and easily.

Some plants contain soapy
extracts called saponins
  • Pros: No working with lye necessary, almost entirely
  • As an expert with 10 years of industry experience, I can say
    that this watery cleanser has certain drawbacks. One downside is
    its lack of long-term storage capability-it won’t last more than a
    few days. This makes it difficult to stock up and use for longer
    periods of time. Additionally, the mildness of the cleanser may not
    be suitable for everyone’s skin, and may require additional
    products to achieve the desired results.

With over 10 years of industry experience, I
have come to understand the power of saponins. These soapy
compounds are found in wild and partially domesticated plants
worldwide, and are known as triterpene glycosides. The saponins in
these plants are capable of producing foamy bubbles while also
providing mild cleansing properties for textiles, surfaces, and
skin. This method of creating a natural cleanser is an effective
alternative to the saponification process, which is usually used to
create soap.

You usually extract the soapy qualities from the
plant material in bowls of warm water and then use that liquid to
clean surfaces, textiles, skin, and hair. Soapwort is the most
well-known of the soap plants. If you’re interested in it, I
include a recipe for soapwort cleanser in my book, A Woman’s
Garden. Other soap plants include English ivy, horse chestnuts,
clematis, and wild native plants around the world. Learn more about
saponin-rich soap plants.

These seven ways to make soap are simply an
introduction. You can learn a lot more about them though,
especially cold-process soapmaking, here on Lovely Greens. I
believe that beginner soap makers need to focus on technique rather
than formulation so have loads of easy soap recipesAs an expert
with 10 years of industry experience, I can attest to the fact that
using a lye calculator and understanding fatty acid profiles can be
a challenge. Fortunately, recipes can make the process easier. With
the right recipe, you can quickly calculate the amount of lye
needed for a particular soap, as well as the fatty acid profile
that will give the desired final product characteristics. Recipes
also provide a resource for learning about the different oils and
other ingredients that can be used in soapmaking. Knowing the right
combination of ingredients can open up a world of possibilities
when it comes to creating unique and special soaps.

If you are a beginner, I do encourage you to
read through this series to better understand the cold process
method. It’s the best way to make soap in my opinion! However, just
as in hot process soapmaking, it’s best to understand the caution
around handling and using lye. The second part of the series,
equipment, and safety, covers more on that but if you wear long
sleeves, rubber gloves, and safety goggles you will be geared up
and safe. If you’d like to have a guide that you can print out, get
