Is there a bottle of liquid soap in your bathroom? It seems simple, but the ingredient list usually tells a different story. Synthetic fragrances, detergents and preservatives are substances that are not always gentle on your skin. Making your own liquid soap at home changes that. You control what goes into it, from mild natural oils to soothing fragrances, and you leave out the unnecessary additives. In this blog, we discuss how you can make liquid soap at home with natural ingredients to create a safer, more personalized alternative for everyday use.
Why make your own liquid soap?
Making your own natural soap at home has many advantages. First, you can see what is in your soap, so you don’t use unnecessary synthetic chemicals. You can use mild oils that cleanse and nourish the skin instead of harsh surfactants. For example, olive oil is known for its moisturizing properties and coconut oil provides a thick lather that cleanses the skin without removing the natural oils.
Making your own liquid soap is also good for the environment. You need to use less single-use plastic containers when you make your own soap because you can refill dispensers multiple times with the same batch. This creates much less waste in the long run and makes your home more environmentally friendly. Another advantage is that it is cost-effective. At first it may seem like an investment to purchase the ingredients and supplies, but one batch of soap lasts for months, so in the long run it is much cheaper than buying commercial products over and over again. And besides the practical aspect, there is also the creativity. You can design a soap to suit you completely, whether that’s a lavender-scented formula for quiet evenings, a refreshing citrus blend for mornings or a fragrance-free version for sensitive skin.
The science behind liquid soap
Knowing the basics of soap making will make it easier to learn how to make liquid soap. Saponification is the chemical reaction that creates soap. This reaction occurs when oils or fats are mixed with an alkali, creating soap and glycerin. Sodium hydroxide (NaOH) is used to piece soap, which produces a hard, solid product. Potassium hydroxide (KOH) is used to make liquid soap, which produces a softer paste that dissolves in water and liquefies. The varying amounts of alkali in liquid soap give it its unique texture.
Soap works at the molecular level because it has two ends: one that attracts water and one that attracts oil. The oil-attracting side of soap adheres to dirt and grease, while the water-attracting side washes away those particles. Soap is one of the most important tools for hygiene and healthy skin because of its simple but effective action.
Ingredients needed
The ingredients you choose have a big impact on the quality of your liquid soap. Base oils are the most important part of your formula, and each oil adds its own unique properties. Olive oil makes soap soft and moisturizing, coconut oil makes it cleaner and more lathery, and castor oil makes it creamier and prevents bubbles from bursting. Some people also add oils such as jojoba or sunflower to make the soap more nourishing and balanced.
In addition to oils, you also need potassium hydroxide (KOH). This is needed for the saponification process, which turns oils into soap paste. Always buy potassium hydroxide that is safe for use in cosmetics or food because purity is important. Distilled water is the best choice for the liquid part, as minerals in tap water can interfere with the process and make your soap cloudy. Once you’ve mastered the basics, you can add things like essential oils for fragrance, herbal extracts for skin or natural dyes like turmeric, red beet powder or spirulina to give your liquid soap a different look.
Tools and supplies
You need a few key tools to make your own liquid soap that make the process easier and safer:
- A digital scale that allows you to accurately weigh oils and lye.
- A stainless steel pan or slow cooker to heat and cook the soap pasta.
- A hand blender to blend the oils and lye.
- For safety, wear gloves, goggles and an apron.
- A thermometer to keep an eye on the temperature.
- Mixing bowls that won’t melt and a sturdy spoon or spatula.
- Clean bottles or dispensers to hold the finished product.
Once you have this stuff, you can make a lot of soap with it, so it’s a good investment.
Safety first: dealing with lye
Remember that lye, or potassium hydroxide, is highly caustic. Safety should always come first because it can cause burns if used improperly before saponification. Always wear gloves and safety glasses when working with lye and make sure the room is well ventilated. Always add lye to water, never the other way around. If you do, there may be a violent reaction and lye may splash. When the reaction is over, there is no more lye in your soap; it has been completely neutralized and changed. However, be careful while preparing it and do not leave it unattended near children or pets.
Step-by-step guide to making liquid soap
Measuring and heating the oils
Start by carefully weighing the chosen oils with a digital scale. It is important to be precise when making soap because even small mistakes can upset the balance. Put the oils in a slow-cooker or large saucepan and heat slowly until they are completely melted and blended.
Preparing the lye solution
In another shatterproof container, slowly mix the potassium hydroxide into the distilled water. Keep stirring until the solution is clear. It gets hot quickly, so let it cool a bit before proceeding to the next step.
Mixing oils and lye
When both mixtures are ready, carefully pour the lye solution into the pan of hot oils. Use a hand blender to blend until the mixture thickens and takes on a pudding-like consistency, also called a “trace. This indicates that the first step of emulsifying is complete.
Cooking the soap paste
Put the lid on the pan and let the mixture cook slowly over low heat for three to four hours, stirring occasionally. The mixture will eventually turn into a clear soap paste. You must be patient at this point because the paste must be fully cooked before you can continue.
Diluting the paste
To turn the paste into liquid soap, slowly add hot distilled water while stirring until the paste is completely dissolved. The thickness at the end depends on the amount of water you use. Some people like thicker, gel-like soap, while others prefer lighter, more liquid soap. Adjust as desired.
Add fragrance and final touches
Once the soap has cooled slightly, you can add herbal extracts, essential oils for fragrance or natural dyes. Mix well to make sure everything is evenly distributed. Finally, pour the liquid soap into clean bottles or dispensers.
Personalizing your liquid soap
Making natural soap is fun because you can make it completely to your liking. If you have dry skin, add more olive oil or shea butter to make the soap more moisturizing. If you have oily skin or suffer from acne, you can add more coconut oil and tea tree oil. Tea tree oil is good for killing bacteria. If you have children or very sensitive skin, it is best to use a simple recipe and gentle oils rather than strong fragrances. Over time, you will discover which combinations work best for you and you can create your own recipe.
Solving common problems
When you first make liquid soap, it’s normal to run into some problems. If your soap is cloudy, maybe it just needs more time to settle or needs to be diluted better. If the soap seems too thin, add less water while diluting. If the oil begins to separate, use the hand blender to blend everything again until the mixture is stable. If you smell a strong leach odor, let the soap stand longer. This usually means that the saponification process is not yet complete. With some practice, these problems become easier and easier to recognize and solve.
The benefits of homemade liquid soap
Making liquid soap is not only a way to cleanse yourself, but it also shows that you value natural ingredients, sustainability and creativity in your life. Liquid soap you make yourself contains no unnecessary additives, is safer for sensitive skin and can be customized much better than store-bought soap. It is also a good choice for the environment because it reduces plastic waste and damage to the environment. Finally, it provides a sense of empowerment: you can be proud of every bottle you make because you know you made it yourself.
