Sodium Lauryl Ether Sulphate (SLES Ungero)

Sodium Lauryl Ether Sulphate (SLES Ungero)

Sodium Lauryl Ether Sulfate (SLES) is an anionic surfactant commonly used in various personal care and cleaning products. It is derived from lauryl alcohol and ethylene oxide, followed by sulfation to produce the final compound. SLES is known for its excellent foaming and cleaning properties, making it a popular ingredient in shampoos, body washes, toothpaste, and household cleaners.

As a surfactant, SLES acts as a detergent and emulsifier, helping to remove dirt, oil, and grease from surfaces. It lowers the surface tension of liquids, allowing them to spread and penetrate more effectively. Additionally, SLES can create a rich and stable foam, enhancing the cleansing experience.

It’s worth noting that SLES can be derived from natural or synthetic sources, and its production may involve the use of petroleum-based ingredients. However, formulations can vary among manufacturers, so it’s important to check product labels or consult the manufacturer directly for specific information on the origin and processing of SLES.

Overall, SLES is widely used due to its effectiveness in cleaning and foaming properties, contributing to its presence in many everyday products.
