Description
Sodium Lauryl Sulfate Product Overview
Sodium lauryl sulfate (C12H25NaO4S) is supplied as white needles, powder or a 28–30% paste. It foams strongly and removes oil and dirt efficiently, which explains its wide use in cleaning and personal care.
In addition, toothpaste producers use it as the main foaming agent, and shampoo and body wash producers use it, often together with milder co-surfactants such as Cocamidopropyl Betaine. Similarly, pharmaceutical companies use pharmacopoeia grades as a wetting agent and lubricant in tablets and capsules, and laboratories use high-purity SDS in protein electrophoresis. Detergent producers also use technical grades.
Because SLS can irritate sensitive skin, many personal care producers combine it with milder surfactants or use Sodium Lauryl Ether Sulfate.
