Request SDS →Sodium sesquicarbonate (CAS 533-96-0) is a double salt of sodium carbonate and sodium bicarbonate, occurring naturally as the mineral trona. HSDB documents its use as a detergent and soap builder, a mild alkaline agent for general cleaning and water softening, in bath salts, and in leather tanning. It is also used to produce sodium carbonate.
Frequently Asked Questions
What is another name for sodium sesquicarbonate?
It is a double salt of sodium carbonate and sodium bicarbonate (CAS 533-96-0), and it occurs naturally as the mineral trona. Trona is the common mineral name for the naturally occurring form. Confirm the CAS and grade on the CoA.
Is sodium sesquicarbonate the same as borax?
No. Sodium sesquicarbonate is a sodium carbonate/bicarbonate double salt, while borax is a sodium borate. They are chemically distinct and not interchangeable. Verify CAS 533-96-0 to avoid confusing the two.
What is sodium sesquicarbonate used for?
HSDB documents its use as a detergent and soap builder, a mild alkaline agent for general cleaning and water softening, a buffering agent in bath salts, and an alkaline agent in leather tanning. It is also used as a feedstock to produce sodium carbonate. RawSource supplies it in bulk for these industrial uses.
Is sodium sesquicarbonate water soluble?
Yes, it is water-soluble and dissolves to give a mildly alkaline solution, which is the basis for its cleaning and water-softening function. Confirm the supplied form and grade against your CoA. RawSource supplies it for industrial cleaning and processing.
What is the cost of bulk sodium sesquicarbonate?
Bulk pricing depends on grade, order volume, and packaging. Request a current quote from RawSource with your target quantity and we will return delivered pricing along with a CoA and SDS. We do not quote fixed list prices online.
