Safety

Carbamide peroxide, also called urea peroxide, urea hydrogen peroxide (UHP), and percarbamide, an adduct of hydrogen peroxide and urea. Like hydrogen peroxide, it is an oxidizer. This compound is a white crystalline solid which dissolves in water to give free hydrogen peroxide; the solubility of commercial samples varies from 0.05 g/mL[1] to more than 0.6 g/mL.[2] The chemical formula is CH6N2O3.

Carbamide peroxide is mainly used as a disinfecting and bleaching agent in cosmetics and pharmaceuticals.[3] As a drug, this compound is used in some preparations for the whitening of teeth.[3][5][6] It is also used to relieve minor inflammation of gums, oral mucosal surfaces and lips including canker sores and dental irritation,[7] and to emulsify and disperse ear wax.[7]

Peracetic acid (also known as peroxyacetic acid, or PAA), is an organic compound with the formula CH₃CO₃H. This organic peroxide is a colorless liquid with a characteristic acrid odor reminiscent of acetic acid. It can be highly corrosive.

Peracetic acid is a much weaker acid than the parent acetic acid, with a pK_a of 8.2.

Peracetic acid arises upon treatment of acetic acid with hydrogen peroxide, the equilibrium constant being 0.37 at room temperature:

H₂O₂ + CH₃CO₂H CH₃CO₃H + H₂O

As an alternative, acetyl chloride and acetic anhydride can be used to generate products with lower water content.

Peracetic acid is produced by continuously feeding acetic acid and hydrogen peroxide into an aqueous reaction medium containing a sulfuric acid catalyst. The reaction is allowed to continue for up to ten days in order to achieve high yields of product according to the following equation.^[2]

Peracetic acid production

Peracetic acid is always sold in solution with acetic acid and hydrogen peroxide to maintain the stability of the chemical. The concentration of the acid as the active ingredient can vary, and usually depends on its application. Additional methods of preparation involve the oxidation of acetaldehyde or, as an alternative, as an end-product of the reaction of acetic anhydride, hydrogen peroxide, and sulfuric acid. Another method involves the reaction of tetraacetylethylenediamine (TAED) in the presence of an alkaline hydrogen peroxide solution.^[2] PAA is also formed naturally in the environment through a series of photochemical reactions involving formaldehyde and photo-oxidant radicals.
