Chemical Description

  • Sodium Lauryl Sulfate (SLS) Needle, also known as Sodium Dodecyl Sulfate (SDS), is an anionic surfactant widely recognized for its properties as a detergent and foaming agent. It is characterized by its needle or flake-like appearance, ranging from white to light yellow. SLS is particularly notable for its high solubility in water, where it exhibits excellent lathering capabilities.
  • SLS finds extensive application in the manufacturing of household and industrial detergents, where its grease-cutting and soil-removing capabilities are highly valued. It is a key ingredient in a variety of cleaning products, including floor cleaners, engine degreasers, and dishwashing liquids.
  • In personal care products, Sodium Lauryl Sulfate is an essential component in the formulation of soaps, shampoos, toothpastes, and foaming facial cleansers, offering deep cleansing properties and the ability to produce a rich foam.
  • The pharmaceutical industry employs SLS as an excipient, utilizing its wetting and solubilizing properties to improve the solubility of poorly soluble drugs, thus enhancing their absorption and efficacy.
  • SLS is also used in the textile and leather industries, serving as an emulsifying agent in the processing of fabrics and leather, aiding in the removal of oils and facilitating the even application of dye.
  • In the realm of scientific research, SLS serves as a standard reagent in protein separation techniques, including polyacrylamide gel electrophoresis, due to its ability to denature proteins.
  • Sodium Lauryl Sulfate's role in bubble baths, shaving creams, and toothpastes can be attributed to its foam-building qualities, improving the user experience and efficacy of these products.
  • Despite its widespread usage, the environmental and health impacts of SLS have prompted research into more skin-friendly and biodegradable alternatives, reflecting the industry's move towards more sustainable and less irritating compounds.
  • Sodium Lauryl Sulfate (SLS) Needle stands out for its versatility across various industries, marked by its effective detergent, surfactant, and foaming properties. Its applicability in a broad spectrum of products from detergents to pharmaceuticals underlines its integral role in modern manufacturing and product development.
