Anionic surfactants are chemical compounds that are used in cleaning products as they have the function of lowering the surface tension of water by making the molecules slide.

They could be called classics as they are the ones that have been used the longest.

Anionic surfactants are chemical substances that have had a very high rate of increase in recent years.

They have specific electrostatic and amphiphilic properties so they are very efficient compounds for the detergent industry.

They are present in many consumer products but pose the problem of their disposal in the environment. In fact, their composition is very different from neutral organic compounds.

Main uses 

• Detergents and Soaps. They are commonly used in dishwashing liquids, laundry detergents, and soaps for their deep cleaning properties, capable of efficiently dissolving grease and dirt.
• Personal Care Products. They are widely used in shampoos, body washes, and other personal hygiene products, where they help to create foam and remove sebum and impurities from the skin and hair.
• Cosmetic Industry. Anionic surfactants are also utilized in some cosmetic products to improve their texture and cleaning ability.
• Industrial Cleaning. They are applied in industrial cleaning solutions for their effectiveness in removing oils, greases, and other difficult substances.

Benefits 

• Biodegradability. Many anionic surfactants are biodegradable, which reduces the environmental impact associated with their use and disposal.
• Cost-Effective. They are generally less expensive to produce compared to other types of surfactants, making them a popular choice for a wide range of applications.
