  • Anionic surfactants are important components of detergents and cleaners because they remove a variety of textile contaminants. Anionic surfactants are particularly effective in fatty soils. However, on contact with skin, they may also interact with it and dry it out, for example, by removing the skin fat.
  • Milder anionic surfactants as used for example in personal cleansers, do not give adequate performance in laundry detergents and cleaners for textiles, especially with regard to fatty soiling.
