ARCHIVING 

NOTOX B.V. will archive the following data for at least 10 years: 

protocol, report and test substance reference sample. 

STATEMENT 

From the structural formula of 1,1,3,3-TETRAMETHYLBUTYL PEROXYPIVALATE it can 

be concluded that the test substance is incapable of developing a dangerous 

amount of (flammable) gas in contact with air, damp air or water. 

Moreover, during the production process the. test substance is washed two times 

with water.
