Applicant's summary and conclusion

Conclusions:
Application of an unspecified amount of Chlorowax 500C (a C12 chlorinated paraffin; 59% chlorinated) to the skin of 200 male and female subjects evidently showed no skin sensitising potential.
Executive summary:

In an unpublished study, Chlorowax 500C (a C12 chlorinated paraffin; 59% chlorinated) was applied to the skin of 200 male and female subjects. No data is available as to the frequency or duration of exposure or the amount of test material applied. No local skin sensitisation reactions were reported in the 200 volunteers.
