SECTION 6: HEALTH HAZARD INFORMATION
Inhalation
Not applicable
Skin contact
Prolonged contact may cause light skin irritation in
sensitive individuals.
Eye contad
Avoid. Any foreign material in the eyes can cause
irritation.

Toxicity
LD5O, Toxicological studies on lignosulfonates
indicate that they are non toxic. During rat tests to
determine toxicity where lignosulfonates were
administered orally, no deaths were produced.
In the literature, LD50 for lignosulfonates has been reported to be 20,000 mg/kg body weight
by ingestion. Materials with LD50 values of 5,000 mg/kg of body weight and greater are
considered to be non toxic.

None
Sensitization effects
None
Irritation
Practically none

SECTION 10: ADDITIONAL INFORMATION
For many years, toxicological studies have demonstrated the non toxic, non hazardous
nature of lignosulfonates. Lignosulfonates were always found to be non toxic.
Use of lignosu!fonates in animal feed and other food related applications is approved by
the US FDA and Agriculture Canada. Use as a pelleting aid for animal feed, in boiler water
treatment, sealing gaskets for food containers, etc. is indicated in Title 21 of the code of
regulations of the US FDA. Use of lignosulfonate for pelletizing animal feed is permitted by
Agriculture Canada in the Feeds Act and Feeds Regulations.
Safe use history of lignosulfonates, government regulations that permit use of
lignosulfonates in animal feeds, and toxilogical studies have all demonstrated that
lignosulfonates are safe, non toxic, non hazardous products.
