Washing Soda (Soda Ash) 1 kg

Sodium Carbonate for Industrial Water Treatment and Household Formulas

Sodium carbonate, commonly sold as washing soda or soda ash, ranks among the most widely used alkaline reagents worldwide by consumption volume. This product belongs to the Acids, Salts, Alcohols, and Alkalis category, which gathers reagents used for pH adjustment, cleaning processes, and chemical reactions across industries. The largest global demand for soda ash comes from glass manufacturing, detergent production, the pulp and paper sector, and water treatment plants, where its ability to soften water and create an alkaline environment is used on an industrial scale.

In manufacturing, sodium carbonate is applied during glass melting, in metallurgy for ore purification, in textile processing before dyeing fibers, and as a component of drilling fluids. In household chemistry it forms the base of many dishwasher powders and tablets, degreasing gels, and descaling agents. By softening water, soda ash improves the performance of surfactants and allows their concentration in a formula to be reduced, which is why it is typically added together with surfactants during the dry-mixing stage, before liquid components are introduced.

Unlike caustic soda, sodium carbonate is a milder alkali and safer to handle, although protective gloves are still recommended. When a stronger saponifying or degreasing effect is needed for tougher stains, formulators often pair it with liquid caustic soda, combining two alkalis of different strength to fine-tune a formula for anything from household cleaning to industrial surface treatment.

The 1 kg package is convenient for home production of cleaning formulas: kitchen degreasing gels, oven cleaners, and water softeners for laundry. Typical dosage ranges from 5 to 30 grams per liter of water depending on the level of soiling. It dissolves best in warm water around 40-50 degrees Celsius rather than cold or boiling water. In decorative and cosmetic formulations, such as fizzing bath bombs, soda ash is combined with organic acids: contact with moisture triggers a reaction releasing carbon dioxide, producing the characteristic fizz. For this purpose succinic acid works well, giving a gentler and longer-lasting fizzing reaction than citric acid.

In household chemistry and personal care formulas, sodium carbonate is sometimes paired with antioxidants to stabilize a mixture during storage. In such cases a small amount of ascorbic acid is added separately from the alkaline component to prevent premature neutralization before use.

Store soda ash in a tightly sealed container in a dry place away from moisture, since the substance is hygroscopic and clumps when exposed to humid air. For small and medium production batches, the 1 kg package suits home workshops and small studios testing a formula before scaling up to larger volumes.

Homemade Dishwasher Booster Powder

Sodium carbonate 300 g

Citric acid substitute (succinic acid) 50 g

Coarse salt 100 g

Baking soda 50 g

Combine all dry ingredients in a large bowl and mix thoroughly until evenly blended, breaking up any lumps with a spoon. Transfer the powder into an airtight jar and add one to two tablespoons to the detergent compartment of a dishwasher alongside a regular detergent tablet to boost water softening and reduce mineral buildup on glassware.
