SODIUM LAURYL SULPHATE

First lauryl alcohol (C₁₂H₂₆O) is reacted with Sulfur trioxide (SO₃) then neutralized with Sodium hydroxide (NaOH) to form Sodium Lauryl Sulfate (SLS).

Sodium Lauryl Sulfate (SLS) is a anionic surfactants and commonly used in cosmetics. It is utilized for its strong cleansing and foaming properties, effectively removing dirt and oils from the skin and hair. It is found in personal care products  where its ability to create lather enhances the sensory experience. As a surfactant, it works by reducing the surface tension of liquids, enabling them to mix more easily and aiding in the removal of impurities during cleansing routines. While effective, this ingredient can sometimes be harsh and potentially irritating to sensitive skin.
