Sodium lauryl ether sulfate, is a chemical used in many detergents and cosmetics, such as shampoos, dishwashing liquid, shower gels, and lotions. It acts as a surfactant, which is a substance that reduces the surface tension of liquids and helps them mix better.

Sodium lauryl ether sulfate structure and properties

This substance is a chemical compound that is obtained by combining fatty alcohols (such as lauryl alcohol) with ethylene oxide and then sulfonating it. It has a polar head (sulfate) and a nonpolar tail (hydrocarbon chain). The polar head dissolves in water, and the nonpolar tail sticks to fats and oils. This special structure makes it a very effective emulsifier and helps oil and water mix.

High foaming properties: Due to its chemical structure, it produces a lot of foam, which helps to effectively clean surfaces.
Emulsifying properties: It can mix oil and water together and create stable emulsions.
Softening: It can make skin and hair soft and smooth.
Colorless and odorless: It is usually a clear, colorless liquid and has a slight odor.
