Natural Soap Making Supplies for Cold Process Soap

When you’re first starting out, all the necessary supplies you need for making cold process soap can feel overwhelming. What items do you absolutely need from that recipe? What items are optional? Here are all the soap making supplies I use for my soaps and when I use them.

Many years ago, I took a soap making course. I didn’t realize at the time just how much I would love it. Since then, it’s turned into one of my favourite pastimes. I love testing out new soap recipes and sharing all of my successes with you.

With soap making, as well as other beauty and herbal products, I have amassed quite a collection of soap making supplies. There are the basics you absolutely need to make cold process soap, like a scale, immersion blender, oils, and lye, and then there are all the fun extras like essential oils for fragrance and mica powders for colour.

Here is my personal collection of things you need for making soap, as well as some of the soaps you might use the soap making supplies for.

Natural Soap Making Supplies for Cold Process Soap

When it comes to soap making, you do need to acquire quite a few supplies upfront. Then, you slowly accumulate more oils, scents, colours, and other fun stuff to make some truly beautiful custom soaps. Here are all the things you need for making soap and the ones I personally use.


The core of your soap making supplies will be the equipment you use every time you make your soap. Alongside every soap recipe I make, these are the materials I pull out and use every single time.

Safety Gear

Don’t even think about skimping out on your safety gear! When working with lye, you want to be extra careful as it can burn the skin before it goes through saponification and turns into soap.

Since lye is caustic, wear gloves the entire time you work on your soap.

Soap Moulds

Soap moulds are where you can really get creative. Loaf soap moulds are the most traditional, where you pour it all in, then cut it into squares or rectangles once it has set.

Alternatively, you can find some really fun shapes to turn your soap into. Here are some of my favourite moulds, though there are so many out there in just about any shape. Just look for silicone ones for easy removal.

Want a DIY soap mould for your first one? Use a milk carton and cut off the top. Once you’re ready to take the soap out, just tear away the milk carton.

It can be difficult to know exactly how much soap to make when working with specialty moulds, so make sure to have two ready for any extra soap that may not fit in the first mould so it doesn’t go to waste.

Oils, Butters, and Fats

Oils and butters will compromise the base of your recipe. You can mix many of these oils together, and I really suggest you do so to get the perfect lather, clean, and moisturizing properties you’re looking for. Now, there are SO many you can use, but these are my go-to cold process soap making supplies.

For most of my soap recipes, I infuse beneficial plants like calendula, chamomile, rose, lavender, and more. You can see how I infuse my oils following these instructions.

I keep lots of infused oils on hand so I can easily use them whenever I need to make a new batch of soap.


You can’t have cold process soap without lye. Luckily, this ingredient is pretty straightforward. If you want to read more about what lye is and how to use it properly, I encourage you to read this post. Otherwise, you will just need lye (also known as sodium hydroxide) mixed with water (ideally distilled).

When lye and water mix together, they generate immediate high heat, so you need a heat-proof container for mixing the two.

Essential Oils

Combining scents and making your own custom perfume blend is one of the best parts about making your own soap. While you can buy fragrance for soaps, I always use essential oils as they’re natural and very effective. Also, you can easily go for an unscented soap as well if you have a sensitive nose.

Another way to display your artistry when making soaps is the colours you decide to you. You can layer different colours for an ombre effect or make swirls in your soap where every piece turns out differently.

Once again, you can buy artificial colourants, but these are the natural colourants I keep in my soap making supplies for cold process soaps.

Of course, decorations are optional. My preferred way to top off my soaps is using dried flower petals I saved from the garden. But there are some other fun ways to top them off as well! Adding decorations is a simple way to polish off your soap.

Extra Ingredients

Some soaps are extra special and call for some more ingredients. Here are some other soap making supplies I use occasionally and the soap recipes I created with them.

Frequently Asked Questions About Soap Making Supplies

Where’s the best place to buy soap-making supplies?

If you live in a city, you might have a store designed especially for soap, candles, and beauty making. Other great places are refillable stores, as they often carry specialty oils, essential oils, and colourants that may be difficult to find elsewhere. Many homestead-style stores that sell things like gardening supplies, animal feed, and more will have sections for at-home soap makers as well.

You can always order your supplies online if you can’t find a hobbyist store.

Are soap making kits worth it?

For a beginner, the convenience of buying a soap making kit is great. It should have your mould, which you can use time and time again, as well as supplies like oils, lye, colourants, and scents. They may also come with a recipe for you to follow.

If you’ve made soap before and have some of the supplies, it’s probably a better deal to get refills of what you need rather than buying a new kit.

What kind of mould should I use?

Loaf soap moulds are the go-to, as you can create one long block of soap that you then cut into traditional bars of soap. No matter the mould type, try to use a silicone mould, as it’s easier to get the soap out once it has been set.
