STEP-BY-STEP GUIDE: HOW TO MAKE HERBAL LIQUID SOAP FROM SCRATCH

Making liquid soap from scratch once seemed daunting to me, but after trying it, I discovered it’s much simpler than it looks!

If you’ve already mastered cold process or hot process soap making, then crafting liquid soap is a natural next step.

This guide was originally part of my newest print book, The Big Book of Homemade Products for Your Skin, Health & Home. Unfortunately, due to space constraints, it didn’t make the final cut—so I’m sharing the tips and recipes here with you instead. Enjoy!

Liquid Soapmaking Tips

Before you dive into making liquid soap, here are a few key points to keep in mind.

YOU’LL NEED A DIFFERENT TYPE OF LYE:

One major difference between liquid soap and bar soap lies in the type of lye used.

Bar soap hardens thanks to sodium hydroxide (NaOH), which acts as the agent that turns oils into solid soap.

Liquid soap, on the other hand, is made by combining oils with potassium hydroxide (KOH). This type of lye is readily available from Etsy or online soap-making suppliers.

Keep in mind that potassium hydroxide purity levels can vary. My recipes are based on 90% purity, a common standard. If your bottle lists a different purity level, you can adjust your recipe using the Soapee calculator. Simply select Liquid Soap – using KOH and input the lye purity number in the first box.

CROCKPOT SIZE FOR LIQUID SOAP:

For this recipe size, I use a 4-quart crock pot (slow cooker), which I picked up at a local big-box store. Make sure to avoid slow cookers with non-stick or Teflon-coated interiors, as these materials can react negatively with lye.

SUPERFAT IS A LITTLE DIFFERENT THAN BAR SOAP:

Liquid soap differs slightly from bar soap in that it requires a lower superfat—typically no higher than 3%. A higher superfat may cause the soap to develop an oily layer.

YOU’LL NEED TO USE MORE WATER IN YOUR RECIPE:

When making liquid soap, the water amount is higher than in bar soap recipes. You’ll need roughly three times the weight of potassium hydroxide in water.

IT’S A GOOD IDEA TO DILUTE SOAP PASTE ONLY WITH WATER AND/OR GLYCERIN:

To ensure your liquid soap has the longest shelf life, dilute the finished soap paste with water or a combination of water and glycerin.

Avoid diluting with herbal teas or milk, as these can cause the soap to spoil more quickly—unless they were cooked into the recipe, like in the Calendula & Coconut Liquid Soap below.

OILS ACT DIFFERENTLY IN LIQUID SOAP THAN BAR SOAP:

When creating your own liquid soap recipes, remember that the choice of oils affects the soap’s consistency.

Using more olive oil results in a thicker soap, while more coconut oil creates a thinner soap.

YOU HAVE LOTS OF HERBAL OPTIONS:

“There are many herbs you can experiment with beyond the ones listed in the recipes below. You can easily substitute them or omit them entirely, using plain oils and water in place of infused oils and herbal teas.

I’m currently working on a resource to provide more detailed options, but in the meantime, here are a few herbs and flowers you might consider exploring:

  • Chamomile
  • Plantain
  • Calendula
  • Dandelion
  • Sunflower
  • Violet leaf”

MY WAY IS NOT THE ONLY WAY:

First and foremost, it’s important to note that this is how I make liquid soap—it’s just one of many methods, not necessarily the best or only method.

There are many fantastic resources available for learning how to make liquid soap. Here are a few to get you started:

  • Soapmaking Forum (I frequently recommend this site; it’s an invaluable resource for soapmakers.) – Liquid Soap & Cream Soap Forum
  • Ultimate HP Soap – 30-Minute Liquid Soap
  • Wholesale Supplies Plus – Learn to Make: Liquid Soap From Scratch
  • Modern Soapmaking – Easy & Quick Tips for Making Liquid Soap Successfully

A quick search for ‘liquid soap’ on any search engine will lead you to even more helpful information!

Liquid Soap Making Overview

Step 1:
Weigh the oils for your recipe and place them into a slow cooker. Turn the heat to high. If you’re using milk powder, briefly blend it into the combined oils using an immersion blender.

Step 2:
Place the distilled water or cooled herbal tea in a stainless steel or heatproof plastic container. While wearing gloves and goggles, weigh out the potassium hydroxide and carefully sprinkle it into the water. Stir well. It’s normal for the lye solution to make a crackling noise when it’s first mixed.

Step 3:
Turn the slow cooker’s heat to low, then pour in the lye solution. Hand stir the mixture for about 5 minutes to ensure it’s fully incorporated. After that, begin blending with your immersion blender. Blend for 1 minute, then allow the blender to rest for a few minutes before blending again for another minute. Avoid running the motor continuously to prevent burning it out. It may take anywhere from 10 to 20 minutes to reach trace.

Step 4:
Keep the heat on low, cover the slow cooker with its lid, and check the mixture every 20 to 30 minutes. Stir with a heatproof spoon or spatula. The soap will start to darken and develop gel-like spots, with other areas separating into clear or cloudy liquid. This is completely normal—just stir everything back together, replace the lid, and continue cooking.

Step 5:
After 1 to 2 hours, the soap batter should become thicker and more concentrated. Continue cooking for another 30 minutes to 1 hour, or until the soap is glossy and resembles Vaseline, as shown in the photo. The total cook time for liquid soap may vary between 2 to 4 hours, depending on the temperature settings of your slow cooker.

Step 6 (Optional):
To check if the soap is fully saponified, you can perform an old-fashioned zap test to ensure there’s no residual lye.

To do this, scoop out 1 teaspoon (5 ml) of soap paste and allow it to cool to a safe, comfortable temperature. Mix the cooled paste with 1 teaspoon (5 ml) of distilled water. Dip your fingertip into the diluted paste and taste it with just the tip of your tongue (don’t swallow the soap!). If it gives your tongue a zapping or electric feeling, the soap needs more cooking. If it just tastes like soap without any zappy sensation, the soap is ready. Be sure to rinse your mouth thoroughly with cold water afterward.

If you’d prefer not to taste the soap but are still unsure, you can turn off the slow cooker, keep the soap covered, and let it sit for 6 hours or overnight to finish the saponification process on its own before proceeding with the next steps of the recipe.

Step 7:
Store the soap paste in covered jars if you want to dilute small amounts at a time. This method extends the shelf life of the undiluted soap paste, which can last for several years. If you choose to dilute the entire batch at once, the shelf life will be shorter. The pH of finished diluted soap typically ranges from 9 to 10.5, and because of its natural alkalinity, it generally doesn’t require a preservative for home use—provided it’s diluted with only distilled water or vegetable glycerine. However, those who sell liquid soap or prefer extra protection often add a preservative like Liquid Germall Plus. I personally don’t add preservatives to my soap, but it’s your choice.

Step 8:
To determine the starting dilution amount, weigh the fully cooked soap paste and multiply the weight by 0.2 (20%) to find how much glycerine you need. Then, multiply the weight by 0.8 (80%) to figure out how much distilled water is required.

For example, if your soap batch weighs 30 ounces (850 g), you would need 6 oz (170 g) glycerine and 24 oz (680 g) distilled water.
If you prefer to dilute a smaller amount, such as 4 ounces of paste, you’d need 0.8 oz (23 g) glycerine and 3.2 oz (91 g) distilled water.

If you don’t have glycerine or choose not to use it, simply substitute more distilled water in its place.

Step 9:
Combine the glycerine and distilled water in a deep stainless steel saucepan and bring to a boil. Add the soap paste to the boiling mixture, stirring gently to ensure the paste is covered by the liquid. Then, cover the pan and turn off the heat, leaving it on the still-hot burner. Allow the mixture to cool to room temperature, stirring occasionally and mashing with a fork, spatula, or potato masher to break up any lumps.

Repeat the boiling and cooling process 1 to 2 more times, allowing the soap paste to dissolve completely. Don’t rush this step or stir too vigorously, as the process takes time. Leave the mixture at room temperature for 2 to 3 days, stirring occasionally, until the paste is fully dissolved.

Step 10:
To add fragrance, gently warm the soap one last time, but do not allow it to simmer or boil. Once the soap is warmed (around 100°F), stir in the essential oil. To calculate the right amount, use 1% of the total diluted soap weight. For example, if you have 8 ounces (237 ml) of diluted soap, you would use 0.08 ounces or about 2.4 ml of essential oil, which is approximately ½ teaspoon. You can also use EO Calc for more precise measurements.

Some essential oils, such as lavender, blend well into liquid soap, while others may cause cloudiness or separation. If this is the case, you might want to use a solubilizer to keep the essential oils mixed evenly. A future article will go into more detail on adding essential oils to liquid soap.

Step 11:
Pour the diluted soap into jars using a fine mesh strainer to catch any undissolved lumps. Let the soap sit undisturbed for several days so it can settle and clear. While the soap can technically be used immediately, giving it time to rest will improve its clarity.

Liquid Soap Recipes

Here are two recipes to kick off your liquid soapmaking journey. You can also check out the Dandelion & Honey Liquid Soap recipe already published on my site. Use the Soapee Calculator, the tips shared earlier in this article, and your creativity to experiment and create your own unique liquid soap recipes!

CALENDULA & COCONUT LIQUID SOAP

This soap captures the essence of sunshine in a jar, thanks to the bright yellow color from calendula flower-infused coconut oil. For added nourishment and appeal, I included a small amount of coconut milk powder in the oils, but you can also use cow or goat milk powder, or skip it altogether. Just keep in mind that milk powders should be used in small amounts for liquid soap to avoid scorching during the long cook time.

It’s important not to dilute soap paste with fresh milk, as it can spoil easily. For more on how to make calendula-infused oil, check out my article on Calendula Oil & Salve.

Yield: 60 ounces (1.7 kg) of diluted soap

Ingredients:

  • 13.75 oz (390 g) distilled water
  • 4.63 oz (131 g) potassium hydroxide (3% superfat)
  • 8 oz (227 g) calendula-infused coconut oil (40%)
  • 3 oz (85 g) castor oil (15%)
  • 9 oz (255 g) high oleic sunflower oil (45%)
  • 1/2 tsp coconut milk powder
  • Up to 6 oz (170 g) vegetable glycerine, for dilution (or more distilled water)
  • Up to 24 oz (680 g) distilled water, for dilution
  • Equal amounts of orange and grapefruit essential oils (see step 10 in the Liquid Soap Making Overview for how to calculate essential oil amounts)

Directions:

  1. In a stainless steel or heatproof plastic container, place the distilled water. Wearing gloves and goggles, weigh out the potassium hydroxide and carefully add it to the water. Stir well and set the lye solution aside.
  2. Weigh the coconut, castor, and sunflower oils into a slow cooker. Blend in the coconut milk powder using an immersion blender. Turn the heat to low, then pour in the lye solution. Alternate between blending with the immersion blender and stirring by hand until trace is reached.
  3. Keep the heat on low, cover the slow cooker with the lid, and check every 30 minutes. Stir with a heatproof spoon or spatula. Continue cooking for approximately 2 to 3 hours.
  4. Store the paste in covered jars. Follow the dilution and scenting guidelines in the full Liquid Soap Making Overview.

HEMP & PLANTAIN LIQUID SOAP

This soap combines plantain-infused coconut oil, extra virgin olive oil, and nourishing hemp oil for a truly unique blend. It’s lightly scented with lavender essential oil, though you can skip the scent for a more natural version.

Note: I used rich, unrefined hemp seed oil from Mountain Rose Herbs to give the soap a subtle green hue. However, hemp seed oil has a shorter shelf life, so it’s best to use this soap within 4 to 6 months. Over time, the green hue may fade to a brownish color, though the soap remains effective and fragrant. I’ve had a jar of this recipe for over a year, and it’s still good, but the color has changed.

Yield: 60 ounces (1.7 kg) diluted soap

Ingredients:

  • 13.75 oz (390 g) distilled water
  • 4.63 oz (131 g) potassium hydroxide (2% superfat)
  • 7 oz (198 g) plantain-infused coconut oil (35%)
  • 2 oz (57 g) castor oil (10%)
  • 6 oz (170 g) extra virgin olive oil (30%)
  • 4 oz (113 g) high oleic sunflower oil (20%)
  • 1 oz (28 g) unrefined hemp or avocado oil (5%)
  • Up to 6 oz (170 g) vegetable glycerine, for dilution (or more distilled water)
  • Up to 24 oz (680 g) distilled water, for dilution
  • Lavender essential oil (see step 10 in the Liquid Soap Making Overview for how to calculate essential oil amounts)

Directions:

  1. Place the distilled water in a stainless steel or heatproof plastic container. Wearing gloves and goggles, carefully weigh out the potassium hydroxide and sprinkle it into the water. Stir well, and set the lye solution aside.
  2. Weigh the coconut, castor, olive, sunflower, and hemp oils into a slow cooker. Turn the heat to low, then pour in the lye solution. Alternate between using an immersion blender and stirring by hand until trace is reached.
  3. Keep the heat on low, cover the slow cooker with the lid, and check every 30 minutes. Stir with a heatproof spoon or spatula. Continue cooking for approximately 2 to 3 hours.
  4. Store the soap paste in covered jars. Follow the dilution and scenting guidelines in the full Liquid Soap Making Overview.

CONCLUSION

In conclusion, making your own liquid soap allows for creative freedom in selecting nourishing oils, natural ingredients, and essential oils to customize the formula to your needs. With the right ingredients, like plantain-infused coconut oil, hemp oil, or calendula, and careful attention to the cooking and dilution process, you can create a luxurious, natural soap that’s both effective and gentle on the skin.

By following the detailed steps provided in the soapmaking process—from creating the lye solution to diluting the soap paste—you’ll be able to craft a product that suits your preferences. Whether you want a soothing lavender scent, a bright, sunny color from calendula, or a gentle, unscented bar, homemade liquid soap offers a unique, customizable experience. Remember that patience is key, and each batch will have its own characteristics, including color changes over time depending on the oils used.

So, whether you’re making soap for personal use or as a creative gift, the process is both rewarding and satisfying. Happy soapmaking!

FRESHMAN YEAR COLLEGE SUPPLY CHECKLIST

What You Need for Class: Freshman Year College Supply Guide. Do you have your college supply list ready yet?

If not, you’re not alone! Unlike in grade school, universities and community colleges don’t typically provide an official list of supplies to bring.

This often leaves incoming freshmen asking: What school supplies do I actually need for college?

Transitioning from high school to college comes with its fair share of uncertainties, and this is definitely one of them. But don’t worry—I’ve got you covered!

In this post, I’ll outline all the essential supplies you’ll need for class and provide a handy, printable freshman college supply list. With this guide, you can start your first semester of college feeling organized and prepared!

What Supplies Do I Need for College?

Starting college can feel like stepping into a whole new world. If you’re feeling anxious or uncertain, don’t worry—that’s totally normal!

Many freshmen share common fears about this big transition, and one of the biggest is not being prepared enough.

As a current college student myself, I know how hectic the weeks leading up to college can be. With everything on your plate, it’s easy to forget about the supplies you need to thrive academically.

But don’t stress—you’ve landed here for a reason! This guide will ease some of your worries and help you check off one of the most important things on your to-do list: getting prepared for class.

Below, I’ll break down 17 essential school supplies every college freshman needs, along with some top recommendations to help you stay organized and ready to tackle your studies!

School Supplies for College List

PENCILS AND ERASERS

Pencils and erasers are number ONE on my college supply list because you’ll use them daily—whether you’re jotting down notes or filling out forms.

While pens might be your go-to writing tool, you’ll definitely need at least one pencil for things like filling out scantrons and multiple-choice tests.

As for the type of pencil, it doesn’t really matter if you choose mechanical or traditional—it’s all about what feels most comfortable for you. Just make sure you have extra lead if you opt for mechanical pencils!

And let’s face it: Mistakes happen. That’s where erasers come in. You’ll definitely want a reliable one for those inevitable missteps!

BLACK/BLUE AND RED INK PENS

Red and black pens may seem like basic supplies, but trust me—they’ve come through for me more times than I can count!

From peer editing to jotting quick notes, they’re versatile tools you’ll find yourself reaching for often.

At my college, professors prefer assignments to be written in black ink, though this may vary depending on your school. It’s always a good idea to check any specific preferences your professors have.

While many students take notes on their laptops, research has shown that writing by hand can help with memory retention. Something to consider when deciding how to organize your notes—handwriting could give you the edge!

HIGHLIGHTERS OR MILDLINERS

It’s no surprise that highlighters (or Mildliners, if you’re into the pastel, aesthetic vibe) make the list of must-haves for college.

With all the reading and homework you’ll be tackling, these tools will quickly become your best friends. They’re perfect for marking key points in textbooks, highlighting important details in notes, or simply making study sessions more organized.

Trust me, when it’s crunch time and you need to quickly review, you’ll be so glad you have them! I know I always am.

FOLDERS

Honestly, you’re going to get so many handouts in college—it can be overwhelming trying to keep track of them all!

To stay organized, grab a couple of folders. I recommend opting for plastic folders, as they’re more durable than paper ones and can withstand spills or wear and tear. A good plastic folder can last you throughout your entire college career!

A tip: Clearly label each folder on the front with the class name or subject. This simple step will save you time when you’re digging through your backpack looking for a specific paper.

For even more organization, consider color coordinating your notebooks, binder, and folders for each class. It’s an easy way to keep things in order and make sure you’re never caught off guard when you need a particular handout!

BINDER/S OR ACCORDION

Another essential for your college supply list is a binder or accordion folder—both are fantastic ways to keep track of and organize all the papers you’ll accumulate throughout the semester.

Some students prefer having a separate binder or folder for each class, while others like to keep everything in one place. It really depends on what works best for you, but I’d suggest starting with less rather than more.

You can always buy more after the semester starts if you need them, and it’s a lot easier to avoid unnecessary clutter in the meantime. Keeping things simple and organized will save you time and stress when you’re searching for that one assignment or syllabus!

PAPER AND BINDER

You’ve got to have a way to control all that loose leaf paper, right? That’s where binder clips come in.

I use them all the time to keep important papers organized, like homework assignments I’ve started or the instructions I need to refer to. They’re perfect for keeping everything neatly together and preventing any loose sheets from getting lost in the shuffle.

And when it’s time to turn in a big project or a stack of papers, binder clips are a lifesaver. They help you present your work neatly and keep everything intact—definitely a must-have for staying organized!

STICKY NOTES

Next up on the school supplies for college list are sticky notes—a must-have for anyone who might be a little forgetful (guilty over here!).

I use sticky notes as colorful reminders for tasks, assignments, or things I need to follow up on. They’re also great for jotting quick notes or highlighting important points in textbooks without actually writing in them.

Flag sticky notes are especially helpful for marking your place in a book or emphasizing key information you’ll need to revisit later. They make organizing and studying so much easier! Plus, they add a little pop of color to your study materials.

SCOTCH TAPE AND SCISSORS

As a college student, tape and scissors will come in handy more often than you might think!

Whether you’re working on projects, need to fix a torn paper, or just find yourself in a situation where something needs to be cut or taped down, having these supplies on hand will save you time and hassle.

Trust me, you’ll be thanking yourself later when you realize you need them, and they’re not hard to pack. So, add a roll of tape and a pair of scissors to your list—you won’t regret it!

NOTEBOOKS

Notebooks are a must-have for taking notes, journaling, or brainstorming ideas.

I’m sure you already figured you’d need these for college, but it’s always reassuring to have that confirmed, right? 😊

How many notebooks you need depends on how much you prefer to write by hand, but a good rule of thumb is to get one spiral notebook per class. This keeps everything organized, and you won’t risk mixing up your notes from different subjects. Plus, having dedicated notebooks for each class makes studying a lot easier when it’s time to review!

FLASH DRIVE

If it wasn’t obvious, much of college work is done digitally these days. From assignments to presentations, you’ll often need to store and share files.

That’s why a portable flash drive is a must-have for your freshman college supply list. When it’s time to print a paper or present in class, you’ll be glad you have one to easily transport your work.

Make sure to grab one before classes start—many students forget this essential item, and it can be a lifesaver when you need to save or transfer files quickly!

ACADEMIC PLANNER

A planner should be a top priority on your college supply list. Whether you used one in high school or not, I highly recommend getting an academic planner for college.

With everything going on—classes, assignments, tests, work, and social life—it’s easy to get overwhelmed. Personally, I find it impossible to keep track of everything without some help. That’s where a planner comes in handy.

I use mine to keep track of my class schedule, important due dates, upcoming test dates, work schedule, personal appointments, and more. It’s an absolute lifesaver that keeps everything organized and helps me stay on top of my busy life.

Trust me, a good planner will make your college life feel so much more put together. I can’t recommend it enough!

WITE-OUT

Let’s face it—none of us are perfect, and mistakes happen. That’s why White-Out is a college essential you’ll want to have on hand.

It’s super useful when you’re working on tests where only pen is allowed, or if you notice a spelling error in your essay just before you’re about to turn it in. White-Out can save you from those last-minute panics and help you present your work without a hitch.

Trust me, it’s one of those small supplies that’ll come in clutch more than once during your college journey!

LOOSE LEAF PAPER

This one’s definitely a no-brainer—loose leaf paper is a must-have for your college supply list! Like pencils, it’ll get daily use in almost every class.

While most notebooks come with perforated paper, some instructors prefer cleaner edges, especially when you’re turning in assignments or writing notes. To be fully prepared, it’s a good idea to get some extra loose leaf paper in addition to your notebooks.

Having this on hand ensures you’re ready for anything, whether it’s last-minute notes, assignments, or just a quick jot of an idea during class!

BACKPACK

Yes, you still need a backpack for college!

Especially if your campus is large and your classes are back-to-back, you’ll need something to carry all your books, supplies, and possibly your laptop. There are usually no lockers, and no time to run back to your car between classes, so having a sturdy backpack is essential.

If you’re bringing a laptop with you, make sure to choose a backpack that’s specifically designed for carrying one. The last thing you want is for your laptop to get damaged—replacing it is not cheap!

Look for a laptop backpack with a padded sleeve for extra protection, and consider one that’s water-resistant for that added peace of mind. You’ll be carrying it around a lot, so it’s worth investing in something that keeps your gear safe and secure!

CALCULATOR

Will you be taking any math classes or other courses that require calculations? If so, a calculator definitely needs to be on your college supply list.

Sure, you might have one on your phone, but keep in mind that phones aren’t allowed during most exams or tests, especially in math-heavy courses. Having a dedicated calculator will save you from scrambling at the last minute.

That being said, it’s a good idea to check with your instructor before purchasing one—some may have brand or model preferences. And if you’re lucky, you might even be able to score a calculator from a graduating student at a great price!

Laptop

As a college student, you will basically live on your laptop.

From researching assignments, writing papers, and communicating with instructors, your laptop will become your essential tool for everything academic and beyond. It’s a must-have in today’s digital age!

Important tip: Before you buy a laptop, make sure it meets the requirements for your college courses. Some programs or majors (like engineering or graphic design) may require specific software that needs a more powerful machine, so double-check the specs to ensure it can run everything you’ll need.

Personally, the laptop I use has been amazing—it meets all my needs and even doubles as a tablet. It’s versatile and portable, which is exactly what you need for college life!

SMALL STAPLER

We may be living in a digital age, but not everything in college is submitted online. Some assignments still require the “old-fashioned” method—on actual paper.

That’s where a mini stapler comes in handy. It’s saved me more than a few times when I’ve had to submit papers or projects in person. You never know when you’ll need to staple your work together, and having one in your backpack ensures you’re always prepared.

You can easily pick one up for cheap at stores like The Dollar Store, Target, or Walmart—a small investment for big peace of mind!

CONCLUSION

Preparing for your freshman year can be overwhelming, but with the right supplies, you’ll feel more confident and ready to take on college life. From essentials like notebooks and pens to the must-have tech gear like a laptop and flash drive, having the right tools will help you stay organized, productive, and prepared for anything.

Remember, everyone’s needs are different, and you can always adjust your list as you go. But starting with these college essentials will give you a solid foundation for a successful first year.
