Description:

Sodium Starch Glycolate is the sodium salt of a carboxymethyl ether of starch. The molecular weight is typically 500000-11000000. Sodium Starch Glycolate is widely used as a pharmaceutical grade dissolution excipient for tablets and capsules.  It absorbs water rapidly. The reason is by absorbing water quickly so the pill swells and breaks apart into small pieces. It can also be used to help form gels. By this way it will swell and accelerate the disintegration of tablets and granules. It consists of oval or spherical granules, 30-100 μm in diameter with some less-spherical granules ranging from 10-35 μm in diameter. Sodium Starch Glycolate can be made from several different starchy foods, for example corn, wheat, rice and potatoes.

As a professional China Sodium Starch Glycolate USP NF BP Pharmaceutical Grade supplier and Manufacturer, FENGCHEN GROUP CO., LTD has been supplying and exporting Sodium Starch Glycolate USP NF BP Pharma Grade from China for almost 10 years.

---------------------

Sodium Starch Glycolate BP (Type A)

DEFINITION

Sodium Starch Glycolate USP NF BP is the 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).

Appearance: Sodium Starch Glycolate USP NF BP is White or almost white, fine, free-flowing powder, very hygroscopic.

Solubility: Sodium Starch Glycolate USP NF BP  is 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.

----------------------

Sodium Starch Glycolate USP NF BP is the sodium salt of carboxymethyl ether. It is white to off-white, odorless, tasteless, and free-flowing powder. Sodium Starch Glycolate USP NF BP is produced by cross-linking and carboxy methylation of potato starch. It can also be produced from other starch foods like corn, wheat, and rice. Sodium Starch Glycolate USP NF BP is practically insoluble in water and insoluble in most organic solvents. It exists in the form of oval, rounded, irregularly shaped, or spherical granules. These granules exhibit considerable swelling upon contact with water. Based on the empirical formula and molecular weight, sodium starch glycolate can be classified into two types: type A and type B. Based on pH value, it is classified into three types that include type C. Type A and Type B are sodium salts of cross-linked, partly O-carboxymethylated potato starch.

 

Sodium Starch Glycolate USP NF BP is widely used in pharmaceuticals, as a disintegrant, in the formation of tablets and capsules. It absorbs water rapidly, which leads to fast disintegration of granules and tablets. Sodium Starch Glycolate USP NF BP dissolves better, which makes it easier for the body to absorb medication. It can also be used as gelling and suspending agent. The usage of sodium starch glycolate in the formation of tablets and capsules involves either wet granulation or direct compression. In higher concentration, it can be used as a dissolution acing agent. Sodium starch glycolate can be more effective when used as an intragranular or extragranular disintegrant or when equally divided between intragranular and extragranular locations. Sodium starch glycolate does not have any side-effect.

 

However, depending on the source, Sodium Starch Glycolate USP NF BP can cause adverse effects on certain individuals. People with allergy to corn or with celiac disease may experience adverse effects. Tablets or capsules that are prepared using Sodium Starch Glycolate USP NF BP have excellent storage properties, due to its physical properties like stability and hygroscopic nature. In order to prevent caking, Sodium Starch Glycolate USP NF BP should be stored in a well-closed container. This can protect it from changes in temperature and humidity. One of the important characteristics of Sodium Starch Glycolate USP NF BP is that its physical properties remain the same for up to 3 years, if handled and stored at a moderate humidity and temperature.

 

Europe and North America regions dominate the global Sodium Starch Glycolate USP NF BP market, followed by Asia Pacific. This growth of the market is attributable to application of sodium starch glycolate in pharmaceuticals. Countries such as the U.S., Switzerland, China, and India have large-sized pharmaceutical companies. Technological advancements for using this product is increasing day by day as medical industry have wide applications globally. Rest of the World held minimum share of the global market in the last few years. However, the market in the region is expected to expand during the forecast period.

-------------------------

Sodium Starch Glycolate USP NF BP takes up more than 20 times its own weight of water. Rapid water penetration into the tablets and powerful swelling results in rapid disintegration.

 

Applications

Sodium Starch Glycolate USP NF BP is suitable for many tablet and capsule formulations. In higher concentrations, Sodium Starch Glycolate USP NF BP can act as a dissolution enhancing agent. Sodium Starch Glycolate USP NF BP is effective when used as intra-granular or extra-granular super- disintegrant, or when divided between these locations.

-------------------------

Sodium Starch Glycolate side effects: Although it isn't likely to cause any side effects in most people, depending on the source it could cause adverse effects for certain individuals. People who are gluten intolerant or who have celiac disease may experience adverse effects if they consume medications made with a wheat-based Sodium Starch Glycolate. Those who suffers a corn allergy should also take steps to determine the source of sodium starch glycolate before using medications.

Usage:

Sodium Starch Glycolate can be used as a disintegrant, a suspending agent and as a gelling agent.

Pharmaceutical companies add Sodium Starch Glycolate to capsules and tablets to help make them disintegrate and dissolve better, making it easier for your body to absorb the medication.
