[[File:Zeoliter korr.JPG|thumb|400px|]] Common detergents today always contain [[surfactants]] of various types for easier cleaning. In order to soften the water, sequestrants in form of phosphates or [[zeolites]] and [[polycarboxylic acids]] are added. The sequestrants should also take care of the hardness formers (calcium and magnesium) of the soiled wash load. Phosphates are difficult to remove from wastewater and often ends up in rivers and lakes, where they cause algae blooms that negatively effect ecosystems and marine life. Has been banned in Europe for use in consumer detergents.'''[1 5''' ] In addition, alkali is added, which consist mostly of soda and / or metasilicate. [[Metasilicate]] also works as a corrosion inhibitor, and a peroxide stabilizer. Because of the mercury structure, however, the substance is classified as hazardous, and with very high acute toxicity and thus belongs to the so-called phase-out substances in the prioritization guide. NPE (nonylphenol ethoxylate)has been banned in Europe as it is persistent in the aquatic environment, moderately bioaccumulative and extremely toxic to aquatic organisms.'''[2 3, 3 4''' ] Sodium lauryl sulfate (SLS)/sodium laureth sulfate (SLES) can cause irritation of the skin and eyes '''[4 1''' ] and 1,4-dioxane is possibly carcinogen, bioaccumulative in the environment, contaminate groundwater and is non-biodegradable.'''[5 2''' ] Other ingredients including linear alkyl sodium sulfonates (LAS), petroleum distillates (a.k.a. naphthas), phenols, optical brighteners, sodium hypochlorite (bleach), EDTA (ethylene-diamino-tetra-acetate) and artificial fragrances, have also been linked to various toxic effects on fish and animals, as well as allergic reactions in humans.
