How Soap Works
Soap molecules have a unique structure. One end is attracted to water (hydrophilic), while the other end is attracted to oils and grease (hydrophobic). This allows soap to lift dirt and grime from surfaces and suspend them in water, allowing them to be rinsed away.
Different Types of Soap
There are many different types of soap, each with its own unique properties. These include bar soaps, liquid soaps, and powdered soaps, among others. The specific fatty acids used in the soap-making process influence the soap's characteristics, such as lather, hardness, and moisturizing properties.
Soap Making
While the exact process of soap making is beyond the scope of a simple explanation for class 7, it involves a chemical reaction called saponification. This reaction combines fats or oils with a strong alkali (like lye) to produce soap and glycerol.
