Sodium lignosulfonate
Encyclopedia
Sodium lignosulfonate is used in the food industry as a de-foaming agent for paper production and in adhesives for items that come in contact with food. It has antimicrobial
and preservative
properties, and is used as an ingredient in animal feeds. It is also used for construction, ceramics, mineral powder, chemical industry, textile industry (leather), metallurgical
industry, petroleum industry, fire-retardant
materials, rubber vulcanization
, organic polymerization

Direct contact should be avoided. Goggles, respirator, and gloves should be used. Primary health risks are:
Antimicrobial
An anti-microbial is a substance that kills or inhibits the growth of microorganisms such as bacteria, fungi, or protozoans. Antimicrobial drugs either kill microbes or prevent the growth of microbes...

Preservative
A preservative is a naturally occurring or synthetically produced substance that is added to products such as foods, pharmaceuticals, paints, biological samples, wood, etc. to prevent decomposition by microbial growth or by undesirable chemical changes....

Metallurgy
Metallurgy is a domain of materials science that studies the physical and chemical behavior of metallic elements, their intermetallic compounds, and their mixtures, which are called alloys. It is also the technology of metals: the way in which science is applied to their practical use...

Fire retardant
A fire retardant is a substance other than water that reduces flammability of fuels or delays their combustion. This typically refers to chemical retardants but may also include substances that work by physical action, such as cooling the fuels; examples of these include fire-fighting foams and...
materials, rubber vulcanization
Vulcanization
Vulcanization or vulcanisation is a chemical process for converting rubber or related polymers into more durable materials via the addition of sulfur or other equivalent "curatives." These additives modify the polymer by forming crosslinks between individual polymer chains. Vulcanized material is...

Direct contact should be avoided. Goggles, respirator, and gloves should be used. Primary health risks are:
- Sneezing and coughing (move to fresh air)
- Eye irritation (wash immediately)
- Skin irritation (wash with soapy water)
- Ingestion (drink large quantities of water and induce vomiting)
Properties
Sodium lignosulfonate has the following properties.- CAS# 8061-51-6
- FlammableFlammabilityFlammability is defined as how easily something will burn or ignite, causing fire or combustion. The degree of difficulty required to cause the combustion of a substance is quantified through fire testing. Internationally, a variety of test protocols exist to quantify flammability...

- Strong oxidizing acidOxidizing acidAn oxidizing acid is a Brønsted acid that is also a strong oxidizing agent . All Brønsted acids can act as moderately strong oxidizing agents, because the acidic proton can be reduced to hydrogen gas. Some acids contain other structures that act as stronger oxidizing agents than hydrogen....
