Soap and surfactants are two essential ingredients used in the manufacturing of cleaning products, including detergents. While both are highly effective at removing dirt and grime from surfaces, they are fundamentally different in how they work.
(why is soap described as a detergent? why is it described as a surfactant?)
To understand why soap is described as a detergent, we must first consider what a detergent is. A detergent is a substance that dissolves or removes dirt, stains, and other substances from surfaces. The active ingredient in most detergents is typically soap, which contains sodium hydroxide or another. This chemical reaction causes the surface to become softened or suspended, making it easier to clean.
However, soap is not just any type of soap; it is specifically designed to effectively remove dirt and grime from various types of surfaces. Detergents contain surfactants, which are molecules that help to create a thin film of water on the surface of the dirty item being cleaned. This layer of water helps to hold onto dirt and grime, allowing the soap to more easily dissolve and lift away from the surface.
So, why is soap described as a detergent when it contains surfactants? Surfactants are added to detergents to enhance their cleaning properties. They help to increase the surface tension between the water and the surface of the dirt, making it easier for the soap to penetrate and dissolve into the dirt. Additionally, surfactants can also help to prevent dirt from sticking to the surface of the item being cleaned, ensuring that it remains clean after washing.

In short, soap is described as a detergent because it contains an active ingredient called soap that helps to soften and suspend dirt and grime, while surfactants help to prevent dirt from adhering to the surface of the item being cleaned. Together, these ingredients make soap a powerful cleaning solution that is widely used in households and commercial settings.
