Sodium Sesquicarbonate Supplier in Malaysia
- Also known as
- Trona
- Urao
Sodium sesquicarbonate supplier for cleaning, water-treatment, metal-finishing and general industrial buyers in Malaysia. It is the double salt of sodium carbonate and sodium bicarbonate, Na2CO3·NaHCO3·2H2O (CAS 533-96-0), and the same material occurs naturally as the minerals trona and urao. Solutions are mildly alkaline, sitting between soda ash and sodium bicarbonate in strength.
Traded forms are white crystals or needles, milled powder and free-flowing granules. Crystals dissolve readily into soak tanks and made-up solutions, powder blends into dry formulations, and granules meter with less dust. State the form and any particle-size limits the process needs.
Buyers use sodium sesquicarbonate as a mild alkaline builder in detergents and hard-surface cleaners, for alkalinity and pH buffering in process and pool water, and in metal cleaning, leather and textile treatment. Lower causticity than soda ash is the reason it is chosen where surfaces, fabrics or operators cannot take a stronger alkali.
It is neither soda ash nor sodium bicarbonate, so ask for sodium sesquicarbonate by name when the double salt is specified. Tell us the form, the specification you work to, the tonnage and where it ships. Pack format, availability and paperwork follow in the quotation.

Sodium Sesquicarbonate grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Sodium sesquicarbonate crystals | white crystals or needles | — | Made-up alkaline cleaning solutions, soak and dip tanks, and batch dissolution where a coarse crystal that goes into water quickly is easier to weigh out than a fine powder. | Bag packing, with the size confirmed with the quotation. |
| Sodium sesquicarbonate powder | milled white powder | — | Dry-blended detergent powders, laundry boosters, hard-surface cleaner concentrates and other formulations where the alkali has to disperse evenly through a solid blend. | Bag packing, with the size confirmed with the quotation. |
| Granular sodium sesquicarbonate | free-flowing white granules | — | Metered and volumetric dosing into water alkalinity and pH control duty, and dry sorbent feeding, where low dust and consistent flow matter more than dissolution speed. | Bag packing, with the size confirmed with the quotation. |

Sodium Sesquicarbonate applications
Safety and handling
Keep sealed in a cool, dry place, since the crystals lose water and cake if left open to warm or humid air. Keep it away from acids, which decompose it with vigorous effervescence. Handle the powder with dust control and the usual gloves and eye protection, and read the safety sheet issued with the grade.
Common questions about sodium sesquicarbonate
What is the difference between sodium sesquicarbonate, soda ash and sodium bicarbonate?
They are three separate materials. Sodium sesquicarbonate is the double salt carrying both carbonate and bicarbonate, so its solutions are more alkaline than sodium bicarbonate and gentler than soda ash. Order each one by name, because substituting changes both the alkalinity and the dose rate.
Is trona another name for sodium sesquicarbonate?
Broadly yes. Trona and urao are the mineral names for naturally occurring sodium sesquicarbonate, and refined material is traded under both descriptions. Say which specification you are working to, since mineral and refined grades are described in different terms.
Which form should I request, crystals, powder or granules?
Crystals and needles go into soak tanks and made-up solutions quickly. Milled powder blends into dry detergent and cleaner formulations. Granules meter with less dust in automated dosing. Send the dosing method and any particle-size limits so the form can be matched.
Why choose sodium sesquicarbonate over soda ash in a cleaning formulation?
It contributes alkalinity and buffering while being less aggressive than soda ash, which matters on softer metals, painted surfaces, leather and fabrics. It also dissolves without the strong heat release of a caustic alkali, so manual make-up is simpler.
Can sodium sesquicarbonate be used to raise water alkalinity?
Yes. It is used to lift carbonate alkalinity and buffer pH in process water, cooling circuits and pool water, where a milder alkali is easier to hold inside a target range. State the water volume, the target range and the dosing equipment with the enquiry.
What should a sodium sesquicarbonate enquiry contain?
Name the form, the particle size where it matters, any specification limits you work to, the tonnage and the site it ships to. Adding the pack format you prefer and the paperwork your goods-in team expects saves an exchange of emails later.
