What is Ammonium lignosulfonate?

Ammonium Lignosulfonate is extensively used as animal feeds, dust suppressant, anti-caking and anti-dusting properties in fertilizer particles, also used to stimulate the germination. These chemicals are odorless and are made available in light tan to dark brown color with the thickness similar to that of motor oil.

What is lignosulfonate used for?

Lignosulfonates are used to disperse pesticides, dyes, carbon black, and other insoluble solids and liquids into water. They are used in tanning leather. They are also used to suppress dust on unpaved roads. Oxidation of lignosulfonates from softwood trees produced vanillin (artificial vanilla flavor).

Can you use lignosulfonate in organic fertilizer?

Calcium lignosulfonate and sodium lignosulfonate have not been removed from the EPA 127 List 4B and are therefore allowed for use as inert ingredients in pesticide products (NOSB, 2009). 128 129 Ammonium lignosulfonate is allowed, with restrictions, for use as a nutrient chelate in organic fertilizer 130 products.

What are the symptoms of exposure to ammonium ligninsulfonate?

SYMPTOMS: Prolonged exposure to the dust of this compound may cause sneezing, coughing or other nuisance symptoms. (NTP, 1992) Acidic salts, such as AMMONIUM LIGNINSULFONATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH’s of less than 7.0.

What is the sulfur content of lignosulfonates?

1 Introduction Property Lignosulfonates Kraft lignin Ref. sulfur amount [wt %] 3.56 – 21 sulfonated content [mmol g −1] 1.25–2.5 0 18 sulfonated content [mmol g −1] 0.7–1.9 0 20 sulfonated content [mmol g −1] 1.38 – 22

Which is more soluble in water kraft lignin or lignosulfonate?

Lignosulfonates have generally more sulfur groups, and thus, a higher degree of sulfonation than that of kraft lignin. Due to the presence of the sulfonated group, lignosulfonates are anionically charged and water soluble.
