other: IVIS (in vitro irritancy score)
Basis:
mean
Score:
12.1

Any other information on results incl. tables

The opacity value of the test item was 121, 15 x Permeability value was 0.013 which resulted in an MS of 12.1.

The opacity value of the vehicle control “Glycerol” was 7.7, 15 x Permeability value was 0.573 which resulted in an MS of 8.2 thus demonstrating that Glycerol had no adverse effects on the test system.
