Table 3. Mean and SD of cell viability measurements and of viability
precentages after 60 min (+/- 1 min) of application and 42 h (+/-4 h)
Predition model: test items that reduce the viability to 50% or below
are irritant (I); test items with a percentage viability above 50% are
considered to be non-irritant (NI).
NC: Negative control
PC: Positive control
The skin irritation
potential of Tetrakis
[[2,2',2"-nitrilotris[ethanolato]](1-)-N,O]zirconium was assessed in
vitro according to OECD Test Guideline 439: In Vitro Skin irritation:
Reconstructed Human Epidermis Test Method.
After 60 +/- 1 min
exposure on the surface of the EpiDerm™ reconstructed human epidermis
and a 42 +/- 4 h post-exposure incubation time, viability of the tissues
was assessed and compared to the negative control. The percentage of
viability obtained was 90.85% and therefore the target substance was
classified as non-irritant to the skin.
