Any other information on results incl. tables

In the study with dermally applied undiluted test material approximately 5% of the labelled tetradecane and 15% of the labelled naphthalene was absorbed over 96 hours.
In the study with the 25% concentration of test material, approximately
 7% of the labelled tetradecane and 16% of the labelled naphthalene was absorbed over 96 hours.

In the passive inhalation study approximately 2.8% (undiluted test
 material) and 1.8% (25% concentration) of the labelled naphthalene was available.  In contrast, approximately 0.2% of labelled tetradecane in undiluted and diluted test material was absorbed.

These studies demonstrate that dilution of the test material in mineral
 oil did not influence absorption of the radiolabelled "spikes" present.
