What is STPP used for?

Sodium tripolyphosphate (STPP) — is widely used as a component for the production of synthetic detergents, water treatment, as well as in the ceramic, paint, varnish and other industries.

What is STPP in detergent?

Sodium tripolyphosphate (STPP) is a solid inorganic compound used in a large variety of household cleaning products, mainly as a builder, but also in human foodstuffs, animal feeds, industrial cleaning processes and ceramics manufacture.

What is pentasodium triphosphate?

Pentasodium Triphosphate is an inorganic salt. PENTASODIUM SALT TRIPHOSPHORIC ACID, PENTASODIUM TRIPHOSPHATE, SODIUM TRIPOLYPHOSPHATE, and TRIPHOSPHORIC ACID, PENTASODIUM SALT.

What is the full form of Na3PO4?

Sodium phosphate (Na3PO4) sodiumphosphate. Sodium orthophosphate, tribasic.

Is STPP a foaming agent?

In cleaning products, STPP improves the ability of detergents to penetrate fibers and other materials. It also aids in foaming, and its pH buffering ability makes it useful as a water softener.

What is the pH of STPP?

Uses. Sodium tripolyphosphate is a binder, stabilizer, and sequestrant that is mildly alkaline, with a pH of 10, and moderately soluble in water, with a solubility of 15g in 100ml of water at 25°C.

Why is pentasodium triphosphate used in toothpaste?

Hydrated Silica + Pentasodium Triphosphate These delicate silicates work together to polish unwanted surface staining from your teeth, brightening them daily back to a beautiful natural white.

What is E450 E451 E452?

E450 (vi) Calcium di hydrogen di phosphate E450b and E450c are renamed as E451 and E452.

Which type of salt is na3po4?

trisodium phosphate, also known as NA3PO4 or sodium phosphoric acid, belongs to the class of inorganic compounds known as alkali metal phosphates.

What ions are in na3po4?

Sodium Phosphate is an ionic compound formed by two ions, Sodium Na+ and Phosphate PO−34 . In order for these two polyatomic ions to bond the charges must be equal and opposite. Therefore, it will take three +1 sodium ions to balance the one -3 phosphate ion. This will make the formula for Sodium Phosphate Na3PO4 .

What is the function of STPP in bar soap?

STPP, Sodium Tripolyphosphate is actually added to detergents as opposed to soap. When mixed with a suitable detergent, it acts as a chelating agent and binds with Mg2+ and Ca2+ ions. Such ions are common and responsible for hard water.

What is the best foaming agent for liquid soap?

Foam or lather is created when foaming agents in soaps, detergents and shampoos mix with air and water. The most common foaming agents used in personal care are chemicals sodium laureth sulfate (SLES), sodium lauryl sulfate (sometimes referred to as sodium dodecyl sulfate or SLS) and coco-glucoside.
