Bars of soap will eventually become smaller and smaller until they are no longer usable. Instead of throwing away small bits of bar soap, however, you can collect them and turn them into liquid soap that you can use to conveniently wash your hands. Here are the steps to making your own.
Gather and dry. You will need a degree of patience in order to create your own liquid soap, especially since you will depend on the leftover slivers of bar soap. In a few months, however, you should be able to collect enough slivers to create a bottle of liquid hand soap. Collect the bits of bar soap, and place in a small dish. Let the soap slivers dry under the sun and then place in airtight Ziploc bags. This will ensure that molds will not grow out of the soap. Soap is usually made from oils and vegetable fat, which can house germs and microbes when left unused for prolonged periods of time. Drying the soap will keep the slivers usable.
Blend. When you have a pound or so of soap, use a small knife to chop these into smaller cubes. Once the soap has been cubed, place these into a blender. Turn on the blender so that the soap is ground down into smaller and finer bits. You may need to add in a few drops of water so that the blender will be able to process the soap bits, especially if the soap is very dry.
Add water. Next, add half a cup of water into the blender and soap slivers. Turn on the blender and allow the mixture to become smooth and creamy. It is best to turn on the blender in medium speed and process in twenty second intervals for around a minute. Add a cup of water, and then turn on the blender again until you reach a rich and creamy consistency.
Add fragrance. Even fragrant bar soap will lose its scent over time, especially if the small sliver has been stored for several months. To add fragrance to your liquid soap, you can use the zest from oranges or other fragrant citrus fruits. Do this by using a zester to remove essence from orange rinds and peeling. Add the fragrance and blend as usual. Add enough zest until you arrive at the scent that you want. You can also use essential oils such as sandalwood and vanilla, if you do not want citrus scented liquid soap. To test the liquid soap, take a dollop and use it on your hands. It should be thick enough not to drip quickly, and should foam when used.
Once you have finished processing the liquid soap, place these into a small bottle and then store these into dispensers that have hand pumps. Add one dispenser for each sink around the house to allow you to easily wash your hands wherever you are. You can also make larger batches of liquid soap that you can use for the whole body while showering.
