ASs have excellent foaming properties, especially if some unsulfated alcohol is retained in the product. ASs are also good detergent in the absence of high water hardness. Food-grade-quality ASs are also used in food and pharmaceutical applications.

ASs readily hydrolyze in hot acid medium. They may cause skin and eye irritation. In the absence of builders, ASs readily form calcium and magnesium salts in the presence of high water hardness, reducing their effectiveness as cleaners
