The primary function of detergents in cleaning is to dissolve dirt and organic materials. Detergents are composed of molecules that have both hydrophobic (water-repelling) and hydrophilic (water-attracting) properties. This unique structure allows them to surround and lift away dirt, grease, and other organic substances from surfaces when mixed with water.

When used in cleaning solutions, the hydrophobic end of the detergent molecule attaches to oils and dirt, while the hydrophilic end interacts with water, allowing these impurities to be washed away easily. This effective encapsulation and removal of grime is why detergents are essential for cleanliness in various applications, from laundry to dishwashing and surface cleaning.

Although some detergents can have fragrances added for an appealing scent and may also have disinfectant properties, their primary role remains focused on breaking down and removing dirt and organic contaminants.
