What It’s Used For

Sesqui® is perfect for a variety of household product and industrial uses such as bath salts, mild industrial and specialty cleaners, swimming pool pH balancers, laundry detergents, and water softeners. It is popular for these varied uses because it combines the benefits of both soda ash and sodium bicarbonate into a single, uniform product. Those benefits include its free-flowing and dust-free characteristics as well as having excellent buffering capacity, complete and rapid dissolving properties in water, superior water softening capabilities, mild yet effective alkali cleaning properties, and a silky-smooth feel. Sesqui® is commonly used in the following:

How It’s Made

Our proprietary sesquicarbonate processing method has been utilized at our facility in Green River, Wyoming, since 1953. This process begins as trona ore is crushed and dissolved. The insoluble materials are separated and removed, and the trona is crystallized as pure sodium sesquicarbonate, or Sesqui®.

Physical mixtures of both sodium carbonate (soda ash) and sodium bicarbonate (baking soda) can be created that approximate the chemical composition of Sesqui®, but Sesqui® is superior to such mixtures because of the following characteristics and benefits:

  • A single particle size that maintains uniformity and eliminates the possibility of separation.
  • Free-flowing, dustless crystals with an average pH of 9.9.
  • An appealing luster that mixtures of soda ash and sodium bicarbonate cannot match.
  • No formation of decahydrate and/or monohydrate when Sesqui® is combined with water.
  • Ability to maintain an inventory of only one product with uniform consistency, instead of two.
