Surfactant vs. Detergent — What's the Difference?
By Tayyaba Rehman — Updated on September 18, 2023
Surfactants are compounds that lower surface tension between liquids, while detergents are cleaning agents containing surfactants.

Key Differences
Surfactants are a broad category of compounds known for their ability to decrease the surface tension between two liquids or between a liquid and a solid. Detergents, on the other hand, are specific types of cleaning agents that utilize the properties of surfactants to remove dirt and grease.

The primary function of surfactants is to act as a bridge between two substances that typically don't mix, like oil and water. Detergents incorporate these surfactants to make them more effective in cleaning by ensuring that oil or dirt gets suspended in water and can be rinsed away.

While surfactants can be found in a multitude of products ranging from shampoos to industrial lubricants, detergents are predominantly linked to cleaning applications, whether for laundry, dishes, or general-purpose cleaning.

Surfactants come in various categories, including anionic, cationic, nonionic, and amphoteric, based on their molecular charge. Detergents may contain one or more types of these surfactants, tailored to specific cleaning requirements.

In essence, while all detergents contain surfactants, not all surfactants are used in detergents. Some surfactants may find applications in industries far removed from cleaning, such as in the medical field or agriculture.

Surfactant
Surfactants are compounds that lower the surface tension (or interfacial tension) between two liquids, between a gas and a liquid, or between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, or dispersants.

Surfactant
A substance composed of lipoprotein that is secreted by the alveolar cells of the lung and serves to maintain the stability of pulmonary tissue by reducing the surface tension of fluids that coat the lung.

Detergent
A detergent is a surfactant or a mixture of surfactants with cleansing properties in dilute solutions. These substances are usually alkylbenzene sulfonates, a family of compounds that are similar to soap but are more soluble in hard water, because the polar sulfonate (of detergents) is less likely than the polar carboxylate (of soap) to bind to calcium and other ions found in hard water.
