SULPHUR
Sulphur is present in laundry detergents as sodium sulphate and minor other compounds. Sodium sulphate is often used as a "manufacturing agent" (filler) with larger quantities used in standard laundry powders than concentrates.
Sulphur degrades in anaerobic (without air) systems to produce hydrogen sulphide (rotten-egg gas) which may be the cause of odour around wastewater systems, such as septic tanks and sewer outlets. This gas is then oxidised and dissolves in water to form sulphuric acid that may have detrimental effects upon plumbing fitting and equipment in aerated wastewater treatment systems.
Whether sulphur products are required or nor is not the purpose of displaying these data. Simply showing that some products are high in sulphur may correlate with the type of product. However, sulphur is an essential plant macro-nutrient and may have a benefit to the landscape plants.
The spelling of "sulphur" as "sulfur" is now acceptable but the former will be used throughout this website.
