What the numbers tell you
At 50 wt% and 20 °C, aqueous hydrogen peroxide has a density of about 1196 kg/m³ (1.196 g/cm³) — roughly 1.20× the density of water. That difference carries straight into volume-to-mass conversions and pump and pipe sizing.

Before you use these numbers
- ▸Laliberte (2009) aqueous-solution correlation for H2O2-water density. Tabulated for 5-50 wt% over 0-40 degC, covering the 35 wt% and 50 wt% commercial grades. Viscosity and heat capacity are not tabulated: the correlation's H2O2 viscosity data covers only 0-20 degC (too narrow for this table) and its heat-capacity data is a single 25 degC point, so both are omitted rather than extrapolated. Concentrations are H2O2 by mass and describe a stabiliser-free solution at the stated strength; commercial grades carry stabilisers that shift properties slightly. Hydrogen peroxide decomposes slowly and is hazardous at high strength - handle per the supplier's safety data. Values are for preliminary design; verify against vendor data for critical service.
- ▸Values are tabulated only inside the 5–50 wt% and 0–40 °C ranges shown; the correlation is not extrapolated beyond them here.
- ▸Figures are for a pure hydrogen peroxide–water system. Commercial grades contain impurities (for example chloride in some caustic grades) that shift density and viscosity; check the supplier's data sheet for a specific product.
- ▸Use for preliminary design; verify for critical service.
