Many people are not aware of what ingredients are used to make soap. We just know that soap makes us clean and that it is slippery when it is wet. We also assume that soap is being rubbed off the bar with the friction of our hands rather than the soap bar dissolves when it comes into contact with water.
The truth of the matter is that your soap bar will dissolve in water with enough time. This is because your soap bar is made with fats, which are soluble in water. This does not mean that a bar of soap will dissolve rapidly if left in a bucket of water, but water will eventually dissolve the entire bar of soap.
How Long Will it Take for a Bar of Soap to Dissolve in Water?
A bar of soap will take about a day to dissolve in warm water. In cold water, it could take a few days for the soap to dissolve. Soap is much easier to melt than it is to dissolve due to the nature of the fats that are used in each bar of soap.
When you use your bar of soap to bathe, you are dissolving small amounts of the bar of soap each time. This is not something that happens rapidly, or bars of soap would be almost useless. The warm water of a bath or a shower will be more likely to dissolve a bar of soap, and having your soap in contact with the moisture in the air in a shower or near a bath can help speed the process.
Most people imagine that a dissolved bar of soap will look more like a melted bar of soap, but that is not the case. The chemical processes are different, which leads to the impression that your soap is not actually dissolving when it is used. Water is the best cleaning product for many reasons, and it can break down all kinds of substances with ease, given enough time.
If your bar of soap did not dissolve in water, it would not be very useful to you for the purposes of washing your body or your hands!
Soap is Water Soluble Given Enough Time
While your soap will not dissolve in a matter of a few hours, you can expect your bar of soap is dissolving every time you use it. This is necessary for a bar of soap to be useful for cleaning purposes. The fats in a bar of soap keep the soap from dissolving rapidly, which is why you might not be sure that the bar of soap you are washing with is actually being affected by the water when you use it. Soap can be fully dissolved in water, given enough time.
