According to this chart 290 ppm DMDM hydantoin that has 92ppm total formaldehyde in it has the same efficacy as 60 ppm formaldehyde.
As this data is from supplier, i wanted to ask you
does the same amount of total formaldehyde for example 200ppm from DMDM hydantoin vs from formalin has the same efficacy or formalin is 50% more effective as in this data?
0.115% DMDM hydantoin 55% (200 ppm total formaldehyde)
0.054% formalin ( 200ppm total formaldehyde)
