Applicant's summary and conclusion

Conclusions:
Tin(II) pyrophosphate is not classified for skin irritation according to Regulation (EC) n. 1272/2008 criteria
Executive summary:

1,5 g of Tin(II) purophosphate were applied to one intact skin site for 3 albino rabbits. The entire hair-slipped part of each animal was then covered with an impervious sleeve for a skin contact period of 24 hours. The animals were observed for 7 days after treatment. None of the intact skin sites was affected.
