Sodium Lignosulfonate is a sodium salt of polysulfonated lignin, which is a dark brownpolymeric material found in wood. Synonym(s): DESULFONATED SPENT PULPING LIQUOR; SODIUM BASE SPENT SULFITE LIQUOR; SODIUM LIGNOSULFONATE; LIGNOSULFONIC ACID, SODIUM SALT; SODIUM POLIGNATE; SODIUM SALT LIGNOSULFONIC ACID; SULFONATED LIGNIN SODIUM SALT; DISPERGATOR REAX; DISPERGATOR UFOXANE; MARASPERSE B; MARASPERSE CBS; MARASPERSE N; MARASPERSE N […]
The sulfur bound in lignosulfonates is oxidized to sulfate – not sulfur – after application. There are no studies in the scientific literature citing sulfate as a causative factor in asthmatic reactions.
Lignins are no more toxic than table sugar. In other words, they are relatively harmless. Animal toxicity studies reveal that baking soda, table salt and Vitamin C all are significantly more toxic than lignins. Perhaps the best testimony to the safety of lignosulfonates is the fact that the U.S. Food and Drug Administration has issued […]
Dioxins are occasionally associated with the pulp bleaching process used in the wood pulp industry. However, since lignosulfonates are removed from the pulp prior to bleaching, dioxins are not manufactured into the product. However, just as with other substances, lignins can contain trace amounts of dioxins if they come into contact with dioxin-containing materials. The […]
A.Lignosulfonates are extremely versatile and are used in a wide variety of industrial applications. While generally associated with dust control and surface stabilization for roads, they are used as binders, dispersants, emulsifiers and sequestrants in a host of products such as gypsum board, animal feed pellets and micronutrient systems.
