“…Hydrogen peroxide vapor can cause stability problems of active ingredients in dry granular mixes such as powder detergents with added bleach particles [2] , [3] , [4] , [5] . The aim of this study was to develop an experimental method to quantify the amount of H 2 O 2 vapor inside powders at an interparticle level.…”

An image-based method for determining H 2 O 2 vapor pressures in powder systems was developed based on cellulose pellets loaded with potassium titanium oxide oxalate (PTO Pellets) as probe particles. Solid titanyl salts change color after exposure to hydrogen peroxide vapor and the quantitative response of PTO pellets to H 2 O 2 has been established by comparing reactions with H 2 O 2 in liquid and solid states. Analysis of pictures of the color changes of PTO Pellets mixed into powders can be used to monitor the presence of ppm levels of H 2 O 2 vapor inside powder systems such as bleach containing dry detergent powders. H 2 O 2 vapor quantification in dry systems with titanyl loaded cellulose particles. Simple fabrication of H 2 O 2 probe particles. High sensitivity with LOD 0.190 ppm H 2 O 2 .

“…The most exposed but partially buried Met222 was found to be the only oxidized Met (the other two Met residues are more structurally hindered and inaccessible to solvent). 169 The chloroperoxidase from Caldariomyces fumago can catalyze a wide range of industrially important oxygen insertion reactions. Unfortunately, it displays low operational stability, especially when H 2 O 2 is used as the oxidant.…”
