Specifications of Sodium Starch Glycolate BP Ph Eur (Type A)
DEFINITION
Sodium salt of a cross-linked partly O-carboxymethylated potato starch.
Content
2.8 per cent to 4.2 per cent of Na (A 22.99) (substance washed with ethanol (80 per cent V/V) and dried).
CHARACTERS
Appearance
White or almost white, fine, free-flowing powder, very hygroscopic.
Solubility
Practically insoluble in methylene chloride. It gives a translucent suspension in water.
Examined under a microscope it is seen to consist of: granules, irregularly shaped, ovoid or pear-shaped, 30-100 µm in size, or rounded, 10-35 µm in size; compound granules consisting of 2-4 components occur occasionally; the granules have an eccentric hilum and clearly visible concentric striations; between crossed nicol prisms, the granules show a distinct black cross intersecting at the hilum; small crystals are visible at the surface of the granules. The granules show considerable swelling in contact with water.
IDENTIFICATION
A. pH (see Tests).
B. Prepare with shaking and without heating a mixture of 4.0 g of the substance to be examined and 20 ml of carbon dioxide-free water. The mixture has the appearance of a gel. Add 100 ml of carbon dioxide-free water and shake. A suspension forms that settles after standing.
C. To an acidified solution, add iodinated potassium iodide solution. The solution becomes blue or violet.
D. Solution S2 (see Tests) gives reaction of sodium.
TESTS
Meets all the tests for Specifications of Sodium Starch Glycolate BP Ph Eur (Type A) mongograph.
Sodium Starch Glycolate BP Ph Eur (Type B)
DEFINITION
Sodium salt of a cross-linked partly O-carboxymethylated potato starch.
Content
2.0 per cent to 3.4 per cent of Na (A 22.99) (substance washed with ethanol (80 per cent V/V) and dried).
CHARACTERS
Appearance
White or almost white, fine, free-flowing powder, very hygroscopic.

TESTS
Meets all the tests for Specifications of Sodium Starch Glycolate BP Ph Eur (Type B) mongograph.
Sodium Starch Glycolate BP Ph Eur (Type C)
DEFINITION
Sodium starch glycolate (type C) is the sodium salt of a cross-linked by physical dehydration, partly O-carboxymethylated starch. It contains not less than 2.8 per cent and not more than 5.0 per cent of Na (A 22.99), calculated with reference to the substance washed with alcohol (80 per cent V/V) and dried.
CHARACTERS
A white or almost white, fine, free-flowing powder, very hygroscopic, soluble in water, practically insoluble in methylene chloride. It gives a translucent gel-like product in water.
Examined under a microscope it is seen to consist of granules, irregularly shaped, ovoid or pear-shaped, 30 µm to 100 µm in size, or rounded, 10 µm to 35 µm in size; compound granules consisting of two to four components occur occasionally; the granules have an eccentric hilum and clearly visible concentric striations; between crossed nicol prisms, the granules show a distinct black cross intersecting at the hilum; small crystals are visible at the surface of the granules. The granules show considerable swelling in contact with water.
IDENTIFICATION
A. It complies with the test for pH (see Tests).
B. Mix with shaking and without heating 4.0 g and 20 ml of carbon dioxide-free water. The mixture has the appearance of a gel. Add 100 ml of carbon dioxide-free water and shake: the gel remains stable (difference from types A and B). Keep the gel for the tests for appearance of gel and pH.
C. To 5 ml of the gel obtained in identification test B add 0.05 ml of iodine solution. A dark blue colour is produced.
D. Solution S (see Tests) gives reaction of sodium.
TESTS
Meets all the tests for Specifications of Sodium Starch Glycolate BP Ph Eur (Type C) mongograph.
Sodium Starch Glycolate USP NF
Sodium Starch Glycolate USP NF
Starch carboxymethyl ether, sodium salt.
Sodium Starch Glycolate is the sodium salt of a carboxymethyl ether of starch or of a cross-linked carboxymethyl ether of starch. It may contain not more than 7.0 percent of Sodium Chloride. The pH and assay requirements for Type A and Type B are set forth in the accompanying table.
| ------- pH ------- __________ ---- % Sodium ---- | |
| Type | Minimum -- Maximum __________ Minimum -- Maximum |
| A | 5.5---- -- 7.5---- __________ 2.8---- -- 4.2 |
| B | 3.0---- -- 5.0---- __________ 2.0---- -- 3.4 |
Identification—
A: Infrared Absorption.
B: A slightly acidified solution of it is colored blue to violet by the addition of iodine and potassium iodide TS 1.
C: To a 2-mL portion of the solution prepared for the test for Limit of iron, add 4 mL of Potassium pyroantimonate solution. If necessary, rub the inside of the test tube with a glass rod. A white, crystalline precipitate is formed.
Potassium pyroantimonate solution—To 2 g of potassium pyroantimonate add 100 mL of water. Boil the solution for about 5 minutes, cool quickly, and add 10 mL of a solution of potassium hydroxide (3 in 20). Allow to stand for 24 hours, and filter.
D: Sodium Starch Glycolate imparts an intense yellow color to a non-luminous flame.
Microbial limits — It meets the requirements of the tests for absence of Salmonella species and Escherichia coli.
TESTS
Meets all the tests for Specifications of Sodium Starch Glycolate USP NF mongograph.
