Piranha solution, also known as piranha etch, is a mixture of sulfuric acid ( H2SO4) and hydrogen peroxide ( H2O2 ). The resulting mixture is used to clean organic residues off substrates, for example silicon wafers. [ 1] Because the mixture is a strong oxidizing agent, it will decompose most organic matter, and it will also hydroxylate most ...
Tooth whitening or tooth bleaching is the process of lightening the color of human teeth. [ 1] Whitening is often desirable when teeth become yellowed over time for a number of reasons, and can be achieved by changing the intrinsic or extrinsic color of the tooth enamel. [ 2] The chemical degradation of the chromogens within or on the tooth is ...
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.
A peroxy acid (often spelled as one word, peroxyacid, and sometimes called peracid) is an acid which contains an acidic –OOH group. The two main classes are those derived from conventional mineral acids, especially sulfuric acid, and the peroxy derivatives of organic carboxylic acids. They are generally strong oxidizers .
Accelerated hydrogen peroxide. 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.
The agents most commonly used to intrinsically change the color of teeth are hydrogen peroxide and carbamide peroxide. Oxygen radicals from the peroxide in the whitening agents contact the stains in the interprismatic spaces within the enamel layer. When this occurs, stains will be bleached and the teeth now appear lighter in color.
This salt is widely used in laundry detergents, as one of the peroxide-based bleaches. Sodium perborate was first obtained in 1898, independently, by Sebastian Tanatarand by P. Melikoff and L. Pissadewsky; the researchers prepared sodium perborate by treating sodium borate with a solution of hydrogen peroxide and sodium hydroxide, but Tanatar ...
She suggests adding two to three drops of clove oil in a teaspoon of coconut or olive oil. "Clove oil's eugenol compound is known for its ability to ease nerve pain," Khan adds. Use over-the ...
