How is Calcium Lignosulfonate Used?

Calcium lignosulfonates are polymers formed from soft trees. Normally, softwood trees are made of three components namely cellulose, hemicellulose, and lignin. However, the lignins are sulfonated during the sulfite pulping process. As a result, they become water-soluble which allows them to be separated from the insoluble cellulose. In simple words, therefore, calcium lignosulfonate can be simply defined as soluble lignins.

How is Calcium Lignosulfonate Used?

Calcium lignosulfonates are exceedingly adaptable. As a result, they can be used in a wide range of industrial settings. Here is a list of ways in which calcium lignosulfonate can be utilized:

  • They are used as water reducing admixture in concrete.
  • Many businesses use them as sequestrants in a variety of goods including gypsum board, animal feed pellets, and micronutrient systems.
  • They are commonly used in making dust control and road surface stabilization products.
  • They can also be used as emulsifiers.
  • Some people use them as dispersing agents.

The Impact of Calcium Lignosulfonates on the Environment

Like any other chemical substance, people are curious about the effect that calcium lignosulfonate for sale has on the environment. This is especially after the rise of many initiatives across the globe that aim at environmental conservation. For this reason, many studies have been done to assess the environmental effects of lignosulfonates. Fortunately, the results have been nothing short of positive.

When properly manufactured and used, calcium lignosulfonate for sale is not detrimental to plants, animals, or aquatic life. This is one of the reasons why the chemical substance has been extensively used in many states over the years. For example, since the 1920s, lignosulfonates have been used to treat dirt roads in Europe and the United States. This implies that they have been thoroughly vetted and found to have no negative effect on humans or animals.

What Kind of Metals does Calcium Lignosulfonate Contain?

Because calcium lignosulfonates are made from wood, they contain metals that are found naturally in trees. However, metal concentrations and types vary based on the species of tree and the soil in which it was grown. Remember, heavy metal levels in lignosulfonates are subject to voluntary industry regulations. Fortunately, metal concentrations in calcium lignosulfonates for sale are typically less than one part per million which is very minimal.

Concern about Dioxins in Calcium Lignosulfonate

In a few instances, dioxins have been linked to the wood pulp industry’s pulp bleaching process. However, this should not be a cause of alarm when using products that contain calcium lignosulfonate. This is because lignosulfonates are extracted from the pulp before the bleaching phase. As a result, dioxins are not incorporated into the products.

However, if lignins come into contact with dioxin-containing materials, they can contain trace levels of dioxins. This is just like other chemical compounds which are capable of contaminating any product. Moreover, regulatory bodies across the globe have determined that airborne contamination from incineration is the leading source of dioxin. That said, dioxins are nearly everywhere and they cannot be fully blamed on lignosulfonates.

Toxicity of Calcium Lignosulfonates

Contrary to popular belief, lignins are as harmless as table sugar. To put it another way, they are quite safe to use, by both humans and animals. Surprisingly, baking soda, table salt, and Vitamin C are all substantially more hazardous than lignins. This is according to numerous animal toxicity tests.

Wind Up

Calcium lignosulfonate can be used in a variety of ways. However, many people hesitate to use it because they fear for their safety. However, the fact that health safety bodies have approved lignosulfonates for use in food contact industries is perhaps the best testament to their safety. Besides this, it has been certified for use in animal feedstuff as a pelletizing agent.
