Calcium Lignosulfonate

What is Calcium Lignosulfonate?

Calcium lignosulfonate is a lignin derivative salt obtained by the sulfonation of wood fibers or plant waste.

• Physical state: Colored powder, slightly odorous
• Packaging type: Bag
• Structure: An environmentally friendly additive with water-retaining, dispersing, and binding properties

Calcium lignosulfonate is a versatile compound widely used in the construction, agriculture, paper, textile, and food industries.

Calcium Lignosulfonate Properties

In Which Industries Is Calcium Lignosulfonate Used?

• Construction Industry
  • Concrete, cement, lime additive
  • Increases durability, enhances water retention capacity, reduces cracking and erosion
• Agricultural Industry
  • Used in the granulation of fertilizers and agricultural chemicals
  • Supports plant growth by increasing the soil’s moisture retention capacity
• Paper Industry
  • Facilitates the separation of cellulose fibers
  • Improves paper quality and strength
• Textile Industry
  • Provides dispersion in painting and printing processes
  • Helps colors become more vivid and lasting
• Food Industry
  • Used as a foam stabilizer in some types of beer

How is Calcium Lignosulfonate Produced?

1. Lignin Extraction
   • Lignin is extracted from wood pulp, plant fibers, or paper waste.
2. Sulfonation Process
   • Lignin is made water-soluble by adding sulfonic acid groups.
3. Reaction with Calcium
   • Sulfonated lignin is reacted with calcium hydroxide (Ca(OH)₂).
   • At this stage, calcium lignosulfonate is formed.
4. Latest Transactions
   • The mixture is filtered, dried, and granulated.
   • It is presented to the end user in bag packaging.

The calcium lignosulfonate obtained as a result of this process is preferred in many industries due to its durability, dispersion power, and environmentally friendly nature.
