- Made in the USA
- SDS & COA Available
- No Minimum Order
- No Contracts
Soda Ash Light Grade 100 is high-purity anhydrous sodium carbonate (Na₂CO₃, CAS 497-19-8), also known as soda ash, disodium carbonate or washing soda. It is a white, odorless granular solid with a typical purity of about 99.2% minimum. Level 7 Chemical, based in Conway, Arkansas, supplies it in 50 lb bags, in quantities from a single bag up to a full 2,700 lb pallet.
The light grade has a lower bulk density than dense soda ash, which makes it a good fit for powder blending and fast dissolving. It is widely used to raise alkalinity and buffer pH, as a detergent builder, for softening hard water, in pool and industrial water treatment, and as a pH adjuster and fixative for fiber-reactive textile dyes.

Which Soda Ash Do You Need?
| Product | Grade | Package | Best for |
|---|---|---|---|
| Soda Ash Light Grade 100 (this product) | Light, anhydrous (0.70–0.90 g/cm³) | 50 lb bag | Detergent and powder blending, textile dyeing, fast dissolving for pH and alkalinity control |
| Soda Ash Dense | Dense, anhydrous (0.86–1.12 g/cm³) | 50 lb bag | Glass making and bulk industrial uses that need a heavier, lower-dust granule |
| Soda Ash pH Increaser | Sodium carbonate | 10 lb bag | Smaller pool and spa jobs that need a pH increaser |
Frequently Asked Questions
What is soda ash light?
Soda ash light is the low-density, anhydrous grade of sodium carbonate (Na₂CO₃). It is used to raise alkalinity and buffer pH, as a detergent builder, for water softening and as a fixative for fiber-reactive dyes.
What is the difference between light and dense soda ash?
Both are the same chemical, anhydrous sodium carbonate. Light grade has a lower bulk density (0.70–0.90 g/cm³) than dense grade (0.86–1.12 g/cm³), so it suits powder blending and fast dissolving, while dense grade is preferred for glass making and uses that need a heavier, lower-dust granule.
Is this soda ash food grade?
No. This is an industrial grade for detergents, water treatment, textiles and general industrial use. It is not sold for food processing.
Can I use soda ash light for tie-dye and fiber-reactive dyes?
Yes. Soda ash is commonly used to raise the pH of the dye bath or pre-soak so fiber-reactive dyes bond to cotton and other cellulose fibers. Follow your dye maker's recipe for the amount to use.
Is soda ash hazardous?
Soda ash is classified as a serious eye irritant (Category 2A) with the signal word Warning and hazard statement H319, Causes serious eye irritation. Avoid creating dust, wear eye and skin protection, and read the Safety Data Sheet before handling.
Is there a minimum order, and do you sell full pallets?
There is no minimum order — you can buy a single 50 lb bag. Volume options of 250 lb, 500 lb, 1,000 lb and a full 2,700 lb pallet (54 bags) are also available.
Do you provide an SDS and Certificate of Analysis?
Yes. The Safety Data Sheet and a sample Certificate of Analysis can be downloaded on this page, and lot-specific COAs are available on request.
We quote multi-pallet, full-truckload and recurring orders. Call us or request a quote and we'll get back to you fast.
