A typical mixture is 3 parts of concentrated sulfuric acid and 1 part of 30 wt. % hydrogen peroxide solution; [1] other protocols may use a 4:1 or even 7:1 mixture. A closely related mixture, sometimes called "base piranha", is a 5:1:1 mixture of water, ammonia solution ( NH 4 OH , or NH 3 (aq) ), and 30% hydrogen peroxide.
Life-threatening, major or permanent damage may result from single or repeated overexposures (e.g., hydrogen cyanide). 3. Major injury likely unless prompt action is taken and medical treatment is given. 2. Temporary or minor injury may occur (e.g., diethyl ether). 1. Irritation or minor reversible injury possible. 0.
Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.

Accelerated hydrogen peroxide (AHP) is a trademark [a] for solution of hydrogen peroxide whose antibacterial efficacy is enhanced by a surfactant and an organic acid. [ 1 ] [ 2 ] It is also a disinfectant / cleaning agent that stabilizes hydrogen peroxide so that it can be used for extended periods of time.
Hydrogen peroxide can be used as an oxidizing mouthwash (e.g. Peroxyl, 1.5%). [59] [80] It kills anaerobic bacteria, and also has a mechanical cleansing action when it froths as it comes into contact with debris in mouth. [59] It is often used in the short term to treat acute necrotising ulcerative gingivitis. [59]
Hydrogen peroxide is always used alongside a neutralizing product. [2] The intention is to prevent the hydrogen peroxide from contact with the eye, which could damage the corneal cells in the epithelium. While this would not result in permanent damage, it can cause an intense burn that can linger even after an eye rinse.
Hydrogen peroxide works best as a propellant in extremely high concentrations (roughly over 70%). Although any concentration of peroxide will generate some hot gas (oxygen plus some steam), at concentrations above approximately 67%, the heat of decomposing hydrogen peroxide becomes large enough to completely vaporize all the liquid at standard pressure.
