Calcium Carbonate USP
Carbonic acid, calcium salt (1:1)
Calcium Carbonate, dried at 200 for 4 hours, contains calcium equivalent to not less than 98.0 percent and not more than 100.5 percent of CaCO3.
Packaging and storage— Preserve in well-closed containers.
Identification— The addition of acetic acid to it produces effervescence (presence of carbonate), and the resulting solution, after boiling, responds to the tests for Calcium.
Loss on drying— Dry it at 200 for 4 hours: it loses not more than 2.0% of its weight.
Acid-insoluble substances— Mix 5.0 g with 10 mL of water, and add hydrochloric acid, drop wise, with agitation, until it ceases to cause effervescence, then add water to make the mixture measure 200 mL, and filter. Wash the insoluble residue with water until the last washing shows no chloride, and ignite: the weight of the residue does not exceed 10 mg (0.2%).
Limit of fluoride— The limit is 0.005%.
Arsenic— The limit is 3 ppm.
Barium— A platinum wire, dipped in the filtrate obtained in the test for Acid-insoluble substances and held in a non-luminous flame, does not impart a green color.
Lead —the limit is 3 ppm.
Iron— To pass the test
Mercury— the limit is 0.5 µg per g.
Limit of magnesium and alkali salts— Mix 1.0 g with 35 mL of water, carefully add 3 mL of hydrochloric acid, heat the solution, and boil for 1 minute. Rapidly add 40 mL of oxalic acid TS, and stir vigorously until precipitation is well established. Add immediately to the warm mixture 2 drops of methyl red TS and then 6 N ammonium hydroxide, drop wise, until the mixture is just alkaline. Cool to room temperature, transfer to a 100-mL graduated cylinder, dilute with water to 100 mL, mix, and allow to stand for 4 hours or overnight. Filter, and to 50 mL of the clear filtrate in a platinum dish add 0.5 mL of sulfuric acid, and evaporate the mixture on a steam bath to a small volume. Carefully heat over a free flame to dryness, and continue heating to complete decomposition and volatilization of ammonium salts. Finally ignite the residue to constant weight.
The weight of the residue does not exceed 5 mg (1.0%).
Heavy metals— the limit is 0.002%.
Organic volatile impurities— meets the requirements.
Calcium Carbonate BP Specifications
CaCO3 -- 100
Action and use: Antacid.
98.5 per cent to 100.5 per cent (dried substance).
White or almost white powder.
Practically insoluble in water.
A. It gives the reaction of carbonates
B. 0.2 ml of solution S (see Tests) gives the reactions of calcium
Dissolve 5.0 g in 80 ml of dilute acetic acid R . When the effervescence ceases, boil for 2min. Allow to cool, dilute to 100 ml with dilute acetic acid R and filter, if necessary, through a sintered-glass filter.
Substances insoluble in acetic acid: Maximum 0.2 per cent.
Chlorides : Maximum 330 ppm.
Sulphates : Maximum 0.25 per cent.
Arsenic: Maximum 4 ppm, determined on 5 ml of solution S.
Barium: To 10 ml of solution S add 10 ml of calcium sulphate solution R . After at least 15 min, any opalescence in the solution is not more intense than that in a mixture of 10 ml of solution S and 10 ml of distilled water R.
Iron: Maximum 200 ppm.
Magnesium and alkali metals : Maximum 1.5 per cent.
Heavy metals: Maximum 20 ppm.
Calcium Carbonate FCC Food Grade as per US Food Chemical Codex
CaCO3 Formula wt 100.09
Calcium Carbonate occurs as a fine, white or colorless, microcrystalline powder. It is stable in air, and it is practically insoluble in water and in alcohol. The presence of any ammonium salt or carbon dioxide increases its solubility in water, but the presence of any alkali hydroxide reduces the solubility.
Function: pH control agent; nutrient; dough conditioner; firming agent; yeast nutrient.
Identification: A sample dissolves, with effervescence, in 1 N acetic acid, in 2.7 N hydrochloric acid, and in 1.7 N nitric acid, and the resulting solutions, after boiling, give positive tests for Calcium.
Assay: Not less than 98.0% and not more than 100.5% of CaCO3 after drying.
Acid-Insoluble Substances: Not more than 0.2%.
Arsenic: Not more than 3 mg/kg.
Fluoride: Not more than 0.005%.
Lead: Not more than 3 mg/kg.
Loss on Drying: Not more than 2%.
Magnesium and Alkali Salts: Not more than 1%.

For ease of swallowing, the tablets should be made as small as possible. The high density of calcium carbonate allow the maximum antacid active to be packed in a small tablet. Calcium carbonates must be granulated before converting to tablets though they have poor compressibility, so are not directly compressible. Granulation involves mixing the calcium carbonate with some binder such as starch, acacia gum or maltodextrin, , usually at a 5 to 10 percent binder level and then agglomerating to a larger particle. All the logic is covered in our directly compressible calcium carbonate product.
