Popular questions
  1. What is sodium laureth sulphate?

    Sodium laureth sulphate (SLES) is an ethoxylated anionic surfactant used for cleansing and foaming in personal care and household cleaning products; it is a different substance from E514(i) sodium sulphate.

  2. What is sodium lauryl sulphate?

    Sodium lauryl sulphate (SLS) is an anionic surfactant and foaming agent commonly used in shampoos, toothpastes, and cleaners; it is not the same as E514(i) sodium sulphate.

  3. Is sodium sulphate soluble in water?

    Yes—sodium sulphate is highly soluble in water in both its anhydrous and hydrated forms.

  4. What is sodium laureth sulphate used for?

    SLES is used as a detergent, wetting, and foaming agent in shampoos, body washes, and household cleaners; it is distinct from E514(i) sodium sulphate.

  5. What is sodium sulphate used for?

    Sodium sulphate (E514i) is mainly used industrially as a filler in powdered detergents and in the kraft process of paper pulping, with additional uses in glass manufacture.

  1. What is gypsum used for?

    In foods (E516), gypsum (calcium sulfate) is used as a stabiliser/firming and anti‑caking agent, a tofu coagulant, and to adjust brewing water; outside food it’s used for plaster, drywall, and as a desiccant.

  2. What is gypsum board?

    Gypsum board (drywall) is a building panel with a calcium sulfate core faced with paper, used for interior walls and ceilings—it's a construction use of the same mineral, not a food application of E516.

  3. What does gypsum do for soil?

    It supplies calcium and sulfate without notably changing pH, and can improve structure and water infiltration in sodic (sodium-affected) soils by displacing sodium; it has little effect on non‑sodic clays.

  4. What is selenite good for?

    Selenite is the crystalline mineral form of gypsum (calcium sulfate); it’s used like gypsum in construction materials and as a source of calcium and sulfate, including limited food uses as additive E516.

  5. How much gypsum to add to soil?

    Apply based on a soil test: typical maintenance rates are about 10–40 lb per 1,000 sq ft (50–200 g/m²) for lawns/gardens, while reclaiming sodic soils can require much more (around 1–4 tons/acre, 2–9 t/ha). Over‑application won’t fix non‑sodic clays and can add unnecessary salts.
