화학적 성질

Aluminum hydroxide, Al(OH)3, also known as aluminum trihydroxide, aluminum trihydrate, aluminum hydrate, hydrated alumina, and hydrated aluminum oxide, is a white to whitish-yellow water-insoluble powder with a specific gravity of 2.42. Aluminum hydroxide is used as a baseforpigments, as a water repellent in textile coatings, and as an antacid in medicine. Aluminum hydroxide is soluble in hydrochloric or sulfuric acids or in sodiumhydroxide.

화학적 성질

Aluminum hydroxide adjuvant is a white hydrogel that sediments slowly and forms a clear supernatant.

용도

aluminum hydroxide is an inorganic compound used to make a product less transparent. It is also used by formulators as a humectant, and to soften, smooth, and protect the skin. In addition it helps control product viscosity. often found in facial masks and make-up preparations.

용도

Mainly used as an Active medicament in an Antacid Formulations, also used in manufacturing of Lake Colors, Inks, glass, effluent treatment, and fire retardants.

생산 방법

Aluminum hydroxide adjuvant is prepared by the precipitation of a soluble aluminum salt by an alkali hydroxide, or the precipitation of an alkali aluminate by acid.

정의

aluminium hydroxide: A white crystalline compound, Al(OH)3; r.d. 2.42-2.52. The compound occurs naturally as the mineral gibbsite (monoclinic). In the laboratory it can be prepared by precipitation from solutions of aluminium salts. Such solutions contain the hexaquoaluminium( III) ion with six water molecules coordinated, [Al(H2O)6]3+. In neutral solution this ionizes:
[Al(H2O)6]3+→H+ + [Al(H2O)5OH]2+
The presence of a weak base such as S2- or CO32- (by bubbling hydrogen sulphide or carbon dioxide through the solution) causes further ionization with precipitation of aluminium hydroxide
[Al(H2O)6]3+(aq) → Al(H2O)3(OH)3(s) + 3H+(aq)
The substance contains coordinated water molecules and is more correctly termed hydrated aluminium hydroxide. In addition, the precipitate has water molecules trapped in it and has a characteristic gelatinous form. The substance is amphoteric. In strong bases the aluminate ion is produced by loss of a further proton:
Al(H2O)3(OH)3(s) + OH-(aq)
[Al(H2O)2(OH)4]-(aq) + H2O(l)
On heating, the hydroxide transforms to a mixed oxide hydroxide, AlO.OH (rhombic; r.d. 3.01). This substance occurs naturally as diaspore and boehmite. Above 450℃ it transforms to γ-alumina.
In practice various substances can be produced that are mixed crystalline forms of Al(OH)3, AlO.OH, and aluminium oxide (Al2O3) with water molecules. These are known as hydrated alumina. Heating the hydrated hydroxide causes loss of water, and produces various activated aluminas, which differ in porosity, number of remaining -OH groups, and particle size. These are used as catalysts (particularly for organic dehydration reactions), as catalyst supports, and in chromatography. Gelatinous freshly precipitated aluminium hydroxide was formerly widely used as a mordant for dyeing and calico printing because of its ability to form insoluble coloured lakes with vegetable dyes.

상표명

Pharmaceutical Applications

Aluminium hydroxide (Al(OH)3) has several medical applications. It is used as an antacid for treating heartburn as well as acid indigestion (reflux oesophagitis). It is also known to have healing properties of peptic ulcers. In patients suffering from kidney failure, who show elevated serum phosphate levels (hyperphosphataemia), Al(OH)3 is used as a phosphate binder.
Al(OH)3 is an amphoteric compound , which means it can react as a base or as an acid. In its application as an anti-acid, Al(OH)3 reacts with any excess stomach acid (mainly HCl) with the formation of AlCl3 and water .
Al(OH)3 + 3HCl → AlCl3 + 3H2O
Al(OH)3 is known to cause constipation, so formulations of anti-acids often include a combination with Mg2+ antacids. Usually, oral antifoaming agents, such as simethicone, are added in order to reduce bloating and discomfort/pain.

Pharmaceutical Applications

Aluminum hydroxide adjuvant is used in parenteral human and veterinary vaccines.It activates Th2 immune responses, including IgG and IgE antibody responses. It is also used for the isolation of certain serum components such as blood clotting factors.

Safety Profile

Poison by intraperitoneal route. Human systemic effects by ingestion: fever, osteomalacia, and gastrointestinal effects. When coprecipitated with bismuth hydroxide and reduced by H2, it is violently flammable in air. Incompatible with chlorinated rubber.

Safety

Aluminum hydroxide adjuvant is intended for use in parenteral vaccines and is generally regarded as nontoxic. It may cause mild irritation, dryness, and dermatitis on skin contact. On eye contact, aluminum hydroxide adjuvant may also cause redness, conjunctivitis, and short-term mild irritation. Ingestion of large amounts may cause gastrointestinal irritation with nausea, vomiting, and constipation. Inhalation of the dried product may cause respiratory irritation and cough. Type I hypersensitivity reactions following parenteral administration have been reported.

Veterinary Drugs and Treatments

Orally administered aluminum hydroxide is used to reduce hyperphosphatemia in patients with renal failure.

저장

Aluminum hydroxide adjuvant is stable for at least 2 years when stored at 4–308℃ in well-sealed inert containers. It must not be allowed to freeze as the hydrated colloid structure will be irreversibly damaged.

비 호환성

When exposed to phosphate, carbonate, sulfate, or borate anions, the point of zero charge for aluminum hydroxide adjuvant decreases.

Regulatory Status

GRAS listed. Accepted for use in human and veterinary parenteral vaccines in Europe and the USA. The limits for use in human vaccines are 0.85 mg aluminum/dose (FDA) and 1.25 mg aluminum/ dose (WHO). There are no established limits for use in veterinary vaccines. Reported in the EPA TSCA Inventory.
