Magnesium Oxide SDS of BP IP USP ACS AR Analytical Reagent FCC Food Grade Manufacturers

Magnesium Oxide

Synonyms: Magnesia
CAS Number: 1309-48-4, Molecular Weight: 40.30, Chemical Formula: MgO, EINECS EC Number: 215-171-9, FEMA: ----,

Light Magnesium Oxide BP Grade
Light Magnesia
Ph Eur
MgO -- 40.30 -- 1309-48-4
Action and use: Antacid; osmotic laxative.

DEFINITION
Content: 98.0 per cent to 100.5 per cent of MgO (ignited substance).

CHARACTERS
Appearance: Fine, white or almost white, amorphous powder.
Solubility: Practically insoluble in water. It dissolves in dilute acids with at most slight effervescence.

IDENTIFICATION
A. 15 g has an apparent volume (2.9.15) before settling of at least 100 ml.
B. Dissolve about 15 mg in 2 ml of dilute nitric acid and neutralise with dilute sodium hydroxide solution. The solution gives the reaction of magnesium.
C. Loss on ignition (see Tests).

TESTS
Solution S: Dissolve 5.0 g in a mixture of 30 ml of distilled water and 70 ml of acetic acid, boil for 2 min, cool and dilute to 100 ml with dilute acetic acid. Filter, if necessary, through a previously ignited and tared porcelain or silica filter crucible of a suitable porosity to give a clear filtrate.
Appearance of solution: Solution S is not more intensely coloured than reference solution.
Soluble substances: Maximum 2.0 per cent.
Substances insoluble in acetic acid: Maximum 0.1 per cent.
Chlorides: Maximum 0.15 per cent.
Sulphates: Maximum 1.0 per cent.
Arsenic: Maximum 4 ppm, determined on 5 ml of solution S.
Calcium: Maximum 1.5 per cent.
Iron: Maximum 0.1 per cent.
Heavy metals: Maximum 30 ppm.
Loss on ignition: Maximum 8.0 per cent, determined on 1.00 g at 900 ± 25 °C.
ASSAY
Dissolve 0.320 g in 20 ml of dilute hydrochloric acid and dilute to 100.0 ml with water. Using 20.0 ml of the solution, carry out the complexometric titration of magnesium.
1 ml of 0.1 M sodium edetate is equivalent to 4.030 mg of MgO.

Magnesium Oxide USP Grade
MgO 40.30 -- [1309-48-4].
Magnesium Oxide, after ignition, contains not less than 96.0 percent and not more than 100.5 percent of MgO.

Labeling: Label it to indicate its bulk density. The indicated density may be in the form of a range.
Identification: A solution in diluted hydrochloric acid meets the requirements of the tests for Magnesium.
Loss on ignition: Transfer to a tared platinum crucible about 500 mg, weigh accurately, and ignite at 800 ± 25 to constant weight: it loses not more than 10.0% of its weight.
Free alkali and soluble salts: Boil 2.0 g with 100 mL of water for 5 minutes in a covered beaker, and filter while hot. To 50 mL of the cooled filtrate add methyl red, and titrate with 0.10 N sulfuric acid: not more than 2.0 mL of the acid is consumed. Evaporate 25 mL of the remaining filtrate to dryness, and dry at 105 for 1 hour: not more than 10 mg of residue remains (2.0%).
Acid-insoluble substances: Mix 2 g with 75 mL of water, add hydrochloric acid in small portions, with agitation, until no more dissolves, and boil for 5 minutes. If an insoluble residue remains, filter, wash well with water until the last washing is free from chloride, and ignite: the weight of the ignited residue does not exceed 2 mg (0.1%).
Limit of calcium: the limit is 1.1%.
Heavy metals: the limit is 20 <g per g.
Iron: the limit is 0.05%.

Magnesium Oxide FCC Food Grade
MgO Formula wt 40.30
INS: 530 CAS: [1309-48-4]

DESCRIPTION
Magnesium Oxide occurs as a very bulky, white powder known as Light Magnesium Oxide or as a relatively dense, white powder known as Heavy Magnesium Oxide. Five grams of Light Magnesium Oxide occupies a volume of approximately 40 to 50 mL, while 5 g of Heavy Magnesium Oxide occupies a volume of approximately 10 to 20 mL. It is soluble in dilute acids, practically insoluble in water, and insoluble in alcohol.
Function: pH control; neutralizer; anticaking agent; freeflowing agent; firming agent.

REQUIREMENTS
Labeling: Indicate whether it is Light Magnesium Oxide or Heavy Magnesium Oxide.
Identification: A solution of sample in 2.7 N hydrochloric acid gives positive tests for Magnesium.
Assay: Not less than 96.0% and not more than 100.5% of MgO after ignition.
Acid-Insoluble Substances: Not more than 0.1%.
Alkalies (Free) and Soluble Salts: Passes test.
Arsenic: Not more than 3 mg/kg.
Calcium Oxide: Not more than 1.5%.
Lead: Not more than 4 mg/kg.
Loss on Ignition: Not more than 10.0%.
