Difference between H2O2 and HUWA-SAN
Hydrogen peroxide
Decomposes slowly, spontaneously in water and oxygen
H2O2
IP
H2O + O2
water
oxygen
Not stable in closed, clean packaging!

Summary
Hydrogen peroxide
 Not stable:
slow, spontaneous
decomposition in closed
packaging
 Almost complete
decomposition in contact
with pollution
 Moderate disinfection
Huwa-San
 Stable in closed packaging
(2 – 3 years)
 Depot-storage effect:
non-reacted hydrogen
peroxide remains
stabilised
 Excellent disinfection
