Soda lye (sodium hydroxide in aqueous solution) is one of the basic chemical raw materials that is used in almost all branches of industry. Literature data also confirm the disinfecting properties of sodium hydroxide. The main recipient of soda lye is the construction industry, which uses the product for:

  • the process of obtaining water glass from silica, which is a component of high-quality silicone adhesives and paints,
  • production of titanium white which is one of the basic components of paints,
  • production of synthetic dyes,
  • the production process of specialized surfactants for the construction and construction industry as:
    • sodium carrier in the process of synthesis of specialized, ionic surfactants, – catalyst (reagent) of the ethoxylation and propoxylation process, – neutralizer (reagent) in the sulfonation process,
  • the final stage of the production process of plastic additives used, among others, in construction as a neutralizing factor,
  • production of concrete additives and cement mortars (superplasticizers, dispersants) as a neutralizing substance.

Other applications of soda lye:

  • synthesis of various organic and inorganic compounds (e.g. as a raw material (sodium carrier) for the production of ionic surfactants),
  • pulp and paper industry (grinding, removing lignin, bleaching pulp and wastewater treatment processes),
  • component of disinfection products in the agri-food industry,
  • processes for obtaining aluminum from bauxite,
  • production of soaps and detergents,
  • neutralization of acidic waste streams and purification of waste gases from acidic components,
  • Textile industry – cotton processing, dyeing synthetic fibers (such as nylon or polyester),
  • water treatment processes,
  • production of dyes and bleaches,
  • obtaining artificial silk,
  • rubber production and regeneration of rubber,
  • mining industry,
  • refining of crude oil and mineral oils,
  • as a laboratory reagent
