Aseprox - FG is designed for use in all type of Aseptic packaging machines (Immersion type, Spray type & Bath type). These machine require high purity, low residue hydrogen peroxide to maintain clean, deposit-free nozzles and heating elements. Aseprox - FG fulfills all the above requirements. Aseprox - FG is strictly conforming to specification laid down by Tetra Pak India Pvt. Limited.

Physical Properties

Aseprox - FG is a clear, colourless liquid. It’s density is slightly higher than of water, but it is miscible with water in all proportions. Hydrogen Peroxide decomposes exothermally to water and oxygen with no toxic residues. The decomposition is normally slow (<1%/yr), but is accelerated by heat and decomposition catalysts, such as metals and their compounds; strong acids and strong alkalis.

Carbamide Peroxide 99 (Dental:Stable)

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]

Hydrogen peroxide–Urea adduct
Carbamide peroxide, also called urea peroxide, urea hydrogen peroxide, and percarbamide, is an oxidising agent, consisting of hydrogen peroxide compounded with urea. The molecular formula is CH6N2O3, or CH4N2O.H2O2. It is a white crystalline solid that releases oxygen in contact with water.

The chemical is a skin, eye and respiratory irritant. It is also corrosive and causes burns. It doesn't hurt at 10% concentration (3% hydrogen peroxide equivalent) but it might hurt at 35% (12% equivalent), causing white chemical burns on skin and gums alike.

Pure carbamide peroxide has the form of white crystals or crystal powder, is slightly soluble in water (0.05 g/mL)[1], and contains approximately 35% hydrogen peroxide.

PHYSICAL STATE -- white crystal
MELTING POINT -- 75 - 85 C (Decomposes)
SOLUBILITY IN WATER -- 80 (g/l at 20 C)
NFPA RATINGS -- Health: 3; Flammability: 1; Reactivity: 0
STABILITY -- Stable under ordinary conditions atleast for 6 month, Air & moisture sensitive.

APPLICATIONS -- Urea Hydrogen Peroxide is an unstable combination of urea and hydrogen peroxide in equal amounts. It is soluble in water, alcohol, and ethylene glycol. It decomposes at 75-85 C or by moisture. It's application is on the release hydrogen peroxide as a source of water-free hydrogen peroxide. It is used as a disinfectant, bleaching agent, catalyst in organic synthesis, blueprint developer, modifier of starches and antistatic agent. It is used as an oxygen source for crops.it is used in formulating oral and dental care products and ear wax removers.

Other Uses:Carbamide peroxide is used to whiten teeth.
Relieve minor inflammation of gums, oral mucosal surfaces and lips including canker sores and dental irritation[4]; and to emulsify and disperse ear wax.

Carbamide peroxide is commonly encountered in cosmetic dentistry, where it is used to "bleach" teeth. The active ingredient is hydrogen peroxide, which acts to oxidise inter prismatic extrinsic staining within tooth enamel. There are several methods of applying the peroxide gel to the tooth ranging from night-guard application at home or in-surgery application. The bleaching obtained is proportional to the length of time the peroxide is applied to the tooth, and the concentration used. The concentration most commonly used for tooth whitening purposes is 15%.
A 10% solution in glycerol is used to treat ulcers and other lesions in the mouth.
A 6.5% concentration solution is used to loosen and remove earwax.
