Introduction




What are natural liquid soaps and why make them?




Natural liquid soaps are soaps that are made from natural ingredients such as vegetable oils, fats, water, and lye. They do not contain any synthetic chemicals, preservatives, or detergents that can harm your skin or the environment. Natural liquid soaps are gentle, moisturizing, and biodegradable. They can be used for washing your hands, body, face, hair, dishes, laundry, and more.


Making your own natural liquid soaps has many advantages over buying commercial ones. First of all, you can save money by using inexpensive and readily available ingredients. Second, you can customize your soap according to your preferences and needs. You can choose the type of oils, fats, fragrance, and color that suit your skin type and personal taste. Third, you can avoid waste and plastic pollution by reusing old bottles or jars to store your soap. Fourth, you can have fun and be creative by experimenting with different recipes and techniques.


Benefits of natural liquid soaps




Natural liquid soaps have many benefits for your health and the environment. Here are some of them:



  • They are gentle on your skin. Unlike commercial soaps that can strip your skin of its natural oils and cause dryness, irritation, or allergic reactions, natural liquid soaps are mild and nourishing. They contain glycerin, a natural humectant that attracts moisture to your skin. They also contain fatty acids that help repair your skin barrier and protect it from infections.



  • They are eco-friendly. Natural liquid soaps are biodegradable and do not pollute the waterways or harm aquatic life. They do not contain any synthetic chemicals or detergents that can disrupt the natural balance of the ecosystem. They also reduce plastic waste by allowing you to reuse old bottles or jars instead of buying new ones.



  • They are versatile. Natural liquid soaps can be used for various purposes around the house. You can use them for washing your hands, body, face, hair, dishes, laundry, and more. You can also add different ingredients such as essential oils, herbs, or clay to enhance their properties or create different effects.

Some of the common vegetable oils and fats that are used for making natural liquid soaps are:



  • Olive oil: a mild and moisturizing oil that produces a soft and creamy soap. It is suitable for all skin types, especially dry and sensitive ones.



  • Coconut oil: a hard and cleansing oil that produces a bubbly and lathering soap. It is suitable for oily and acne-prone skin, but can be drying if used in excess.



  • Palm oil: a hard and stable oil that produces a hard and long-lasting soap. It is suitable for all skin types, but can be controversial due to its environmental impact.



  • Castor oil: a thick and sticky oil that produces a rich and conditioning soap. It is suitable for all skin types, but can be sticky if used in excess.



  • Sunflower oil: a light and moisturizing oil that produces a soft and silky soap. It is suitable for all skin types, but can go rancid quickly if not stored properly.



  • Sweet almond oil: a light and nourishing oil that produces a smooth and gentle soap. It is suitable for all skin types, especially dry and irritated ones.



  • Grapeseed oil: a light and astringent oil that produces a thin and cleansing soap. It is suitable for oily and acne-prone skin, but can go rancid quickly if not stored properly.



  • Cocoa butter: a hard and creamy fat that produces a hard and moisturizing soap. It is suitable for dry and mature skin, but can be greasy if used in excess.

How to make natural liquid soaps: step by step instructions




Now that you have gathered all the ingredients and equipment, you are ready to make your own natural liquid soaps. Here are the steps you need to follow:


Step 1: Prepare the lye solution




The first step is to prepare the lye solution. Lye is a caustic substance that can cause severe burns if it comes in contact with your skin or eyes. Therefore, you need to handle it with care and wear protective gear such as gloves, goggles, and a mask. You also need to work in a well-ventilated area and keep children and pets away from your workspace.


To make the lye solution, you need to measure the amount of lye and water needed for your recipe using a digital scale. Then, you need to pour the water into a heat-resistant glass or plastic container and slowly add the lye while stirring with a wooden spoon or spatula. Be careful not to splash or inhale the fumes. The mixture will heat up and become cloudy. You need to let it cool down to about 120F (49C) before using it.


Step 2: Melt the oils and fats




The next step is to melt the oils and fats. You need to measure the amount of oils and fats needed for your recipe using a digital scale. Then, you need to put them in a stainless steel or enamel pot and heat them over low to medium heat until they are completely melted. You need to stir them occasionally with a wooden spoon or spatula. You need to let them cool down to about 120F (49C) before using them.


Step 3: Mix the lye solution and the oils




The third step is to mix the lye solution and the oils. You need to make sure that both the lye solution and the oils are at the same temperature of about 120F (49C). Then, you need to slowly pour the lye solution into the pot with the oils while blending with a stick blender. You need to blend until you reach a light trace, which means that the mixture has thickened slightly and leaves a faint trail when you lift the blender. This may take anywhere from 5 to 15 minutes depending on your recipe.


Step 4: Cook the soap paste




The fourth step is to cook the soap paste. You need to transfer the soap mixture from the pot to a slow cooker or crockpot and set it on low heat. You need to cover it with a lid and let it cook for about 3 to 4 hours, stirring it every 15 to 30 minutes with a wooden spoon or spatula. The soap paste will go through different stages as it cooks, such as separating, bubbling, gelling, and becoming translucent. You will know that it is done when it looks like mashed potatoes or vaseline.


Step 5: Dilute the soap paste




The fifth step is to dilute the soap paste. You need to measure the amount of water needed for your recipe using a digital scale. Then, you need to heat it up in a pot over low to medium heat until it is hot but not boiling. You need to add some of the water to the soap paste in the slow cooker or crockpot and stir well until it dissolves. You may need to use a stick blender or a whisk to help break up any clumps. You need to repeat this process until you have used up all of the water and have a smooth liquid soap.


Step 6: Add fragrance and color (optional)




The sixth step is to add fragrance and color if you want. You can use essential oils, fragrance oils, herbs, spices, clay, mica, or other natural ingredients to scent and color your soap. However, you need to be careful not to add too much as they can affect the pH or consistency of your soap. You also need to make sure that they are compatible with your soap base and do not cause any adverse reactions. You can test a small amount of your soap on your skin before using it.


to add them to your liquid soap and stir well until they are evenly distributed. You can use a stick blender or a whisk to help incorporate them.


Step 7: Bottle and label your soap




The final step is to bottle and label your soap. You need to let your liquid soap cool down completely before bottling it. You can use any clean and dry bottles or jars that have a tight-fitting lid or cap. You can also reuse old bottles or jars that you have washed and sterilized. You need to use a funnel or a pitcher to transfer your liquid soap into the bottles or jars. You need to leave some headspace at the top to allow for expansion.


You also need to label your soap with its name, date, ingredients, and any other information that you want to include. You can use stickers, tags, or markers to create your labels. You need to store your soap in a cool and dark place away from direct sunlight and heat. Your soap should last for about 6 months to a year if stored properly.


Tips and tricks for making natural liquid soaps




Here are some tips and tricks that can help you make better natural liquid soaps:


How to test the pH of your soap




The pH of your soap is an indicator of how acidic or alkaline it is. The ideal pH range for liquid soaps is between 9 and 10. If your soap is too acidic, it can be harsh on your skin and cause irritation. If your soap is too alkaline, it can be drying on your skin and cause cracking.


To test the pH of your soap, you can use a pH meter or strips that you can buy online or at a local store. You need to dip the meter or strip into a small sample of your soap and compare the reading or color with the scale provided. If your soap is within the desired range, you are good to go. If not, you may need to adjust it by adding more water or lye.


How to adjust the consistency of your soap




The consistency of your soap is a matter of personal preference. Some people like their soap thick and creamy, while others like it thin and runny. You can adjust the consistency of your soap by adding more or less water when diluting it.


To adjust the consistency of your soap, you can use a digital scale to measure the amount of water you add or remove from your recipe. You can also use a blender or a whisk to help mix the water and the soap paste. You can test the consistency of your soap by pouring some into a bottle or jar and shaking it. If it flows easily, it is thin. If it clumps or sticks, it is thick.


How to prevent separation and spoilage of your soap




Separation and spoilage are common problems that can affect your liquid soaps over time. Separation occurs when the oils and water in your soap separate into layers. Spoilage occurs when bacteria or mold grow in your soap and cause it to smell bad or change color.


To prevent separation and spoilage of your soap, you need to follow these tips:



  • Use distilled water instead of tap water to make your lye solution and dilute your soap paste. Distilled water is free of minerals and impurities that can cause separation or spoilage.



  • Add a preservative such as vitamin E oil, grapefruit seed extract, rosemary oleoresin extract, or sodium lactate to your soap. A preservative can help extend the shelf life of your soap by inhibiting the growth of bacteria or mold.



  • Shake your bottle or jar before using your soap. Shaking can help recombine the oils and water in your soap and prevent separation.



  • Store your soap in a cool and dark place away from direct sunlight and heat. Sunlight and heat can cause oxidation and degradation of your soap.
