Toxicological Reviews, 2004
Hydrogen peroxide is an oxidising agent that is used in a number of household products, including general-purpose disinfectants, chlorine-free bleaches, fabric stain removers, contact lens disinfectants and hair dyes, and it is a component of some tooth whitening products.

The American Journal of Surgery, 1951
Abstract There is no doubt that enemas using hydrogen peroxide solutions are effective in relieving fecal impactions. It is apparent, however, that the strength of the solutions used must be closely supervised in order to avoid complications. In my experience no more than 30 cc. (1 ounce) or at most 60 cc. (2 ounces) of a U. S. P.

Nature, 1958
AFTER consultation with Holman, his experiment1 was repeated as closely as possible in all details, except the strain of rat used, which was an inbred strain of Wistar origin. Experimental animals and controls carried tumours of the 9th, 10th, 11th and 15th successive transplants into this strain of a Walker carcinoma obtained from the Chester Beatty ...

Photoreduction of hydrogen peroxide by hydrogen
The Journal of Physical Chemistry, 1976The photoreduction of hydrogen peroxide in water under hydrogen of up to 100 atm pressure has been investigated. The reaction involves a chain mechanism with the quantum efficiency for the disappearance of hydrogen peroxide being strongly dependent upon the concentration of hydrogen peroxide. A maximum quantum efficiency of about 35 mol/einstein occurs

Reactions of Hydrogen Atom with Hydrogen Peroxide
The Journal of Physical Chemistry A, 2007Rate coefficients are calculated using canonical variational transition state theory with multidimensional tunneling (CVT/SCT) for the reactions H + H2O2 --> H2O + OH (1a) and H + H2O2 --> HO2 + H2 (1b). Reaction barrier heights are determined using two theoretical approaches: (i) comparison of parametrized rate coefficient calculations employing CVT ...

Hydrogen peroxide and hematin in microsomal lipid peroxidation
Journal of Inorganic Biochemistry, 1981Lipids of rat liver microsomes underwent peroxidation with production of malondialdehyde in the presence of H2O2 and hematin. Rates of peroxidation of 27-33 nmol of MDA formed/mg of microsomal protein/30 min were measured with 5 mM H2O2 and 10 microM hematin at 22 degrees C. Histidine (0.01 M) caused a 55% inhibition.

Ocular Response to Hydrogen Peroxide
Optometry and Vision Science, 1988A controlled, randomized, double-masked study was conducted on eight human subjects to determine the threshold level of hydrogen peroxide, which is toxic when introduced into the eye via a high water content (75%; Durasoft 4) hydrogel contact lens. Subjective comfort, conjunctival hyperemia, corneal and conjunctival epithelial staining, and corneal ...

Troilite oxidation by hydrogen peroxide
Journal of Colloid and Interface Science, 2006The kinetics and mechanism of troilite oxidation by H(2)O(2) was studied at temperatures of 25 and 45 degrees C. Solutions within the range 0.1-0.85 mol L(-1) H(2)O(2) in HClO(4) (0.01-0.1 mol L(-1)) were used as dissolution media. The experimental amount of dissolved iron was plotted versus t(n), with n ranging from 0.25 to 1.55.
