N-aminoethylpiperazine
for piperazine:
Exposure to piperazine and its salts has clearly been demonstrated to cause asthma in occupational settings. No NOAEL can be estimated for
respiratory sensitisation (asthma).
Although the LD50 levels indicate a relatively low level of oral acute toxicity (LD50 1-5 g/kg bw), signs of neurotoxicity may appear in humans
after exposure to lower doses.
Ethyleneamines are very reactive and can cause chemical burns, skin rashes and asthma-like symptoms. It is readily absorbed through the skin
and may cause eye blindness and irreparable damage.
The material may produce moderate eye irritation leading to inflammation. Repeated or prolonged exposure to irritants may produce
conjunctivitis.
The material may cause severe skin irritation after prolonged or repeated exposure and may produce on contact skin redness, swelling, the
production of vesicles, scaling and thickening of the skin. Repeated exposures may produce severe ulceration.

The following information refers to contact allergens as a group and may not be specific to this product.
Contact allergies quickly manifest themselves as contact eczema, more rarely as urticaria or Quincke's oedema.

Asthma-like symptoms may continue for months or even years after exposure to the material ends. This may be due to a non-allergic condition
known as reactive airways dysfunction syndrome (RADS) which can occur after exposure to high levels of highly irritating compound.
