RS-Freetext:

Explosive vapour mixtures are formed at atmospheric pressure when the  hydrogen peroxide concentration in the vapour phase exceeds 26 mol %.  This vapour concentration is, for example, reached at solution  temperatures above 110°C of a 100 wt % aqueous hydrogen peroxide solution  or at solution temperatures above 125°C of a 75% aqueous hydrogen  peroxide solution. Aqueous hydrogen peroxide solutions with  concentrations below about 70% do not reach the critical concentration in  the vapour phase.

Applicant's summary and conclusion

Executive summary:

Explosive vapour mixtures are formed at atmospheric pressure when the hydrogen peroxide concentration in the vapour phase exceeds 26 mol %. This vapour concentration is, for example, reached at solution temperatures above 110 °C of a 100 wt % aqueous hydrogen peroxide solution or at solution temperatures above 125 °C of a 75 wt % aqueous hydrogen peroxide solution. Aqueous hydrogen peroxide solutions with concentrations below about 70 % do not reach the critical concentration in the vapour phase.
