Why Does Soap Actually Clean? The Science Behind How Soap Works

Soap seems almost too ordinary to be interesting. You rub a bar between your hands, add water and watch the foam appear before rinsing everything away. But what actually happens to the dirt and grease on your skin? Water alone struggles to remove oily substances because oil and water do not mix. Soap solves this problem using molecules with two very different ends. One is attracted to water, while the other is attracted to oils and grease. That simple chemical trick allows soap to lift unwanted substances from your skin and carry them away when you rinse.
