ACUTE TOXICITY OF THE SUPERABSORBENT POLYMER
INGESTION
Single dose oral toxicity is considered to be low. The oral LD50 for rats is >2500mg/Kg. No hazards anticipated from swallowing small
amounts incidental to normal handling operations.
SKIN CONTACT
A single prolonged exposure is not likely to result in the material being absorbed through skin in harmful amounts. The LD50 for skin
absorption in rabbits is >2000mg/kg.
IRRITATION OF THE SUPERABSORBENT POLYMER
SKIN
Prolonged or repeated exposure not likely to cause significant skin irritation.
EYES
May cause eye irritation. May cause very slight transient (temporary) corneal injury.
INHALATION
Dust may cause irritation to upper respiratory tract (nose and throat).
MUTAGENICITY
In vitro mutagenicity studies were negative. Animal mutagenicity studies were negative.
CARCINOGENICITY
A chronic (two years) lifetime inhalation study with micronized superabsorbent polymer dust (to get completely respirable particles)
performed on rats resulted in a non – specific inflammatory response in the lungs of the rats, followed in the highest chronic
exposure level by tumour development in some animals (regarding Exposure Controls/Personal Protection). In the absence of chronic
inflammation, tumours are not expected. The study found a definite NOEL of 0.05mg/m of micronized superabsorbent polymer dust.
