Sodium Starch Glycolate
Sodium starch glycolate is a white or almost white free-flowing very hygroscopic powder. Synonyms: Carboxymethyl starch, sodium salt; carboxymethylamylum natricum; Explosol; Explotab; Glycolys; Primojel; starch carboxymethyl ether, sodium salt; Tablo; Vivastar P. CAS No. 9063-38-1. Product ID: PE-0643. Mole weight: 5×10^5~1×10^6. Category: Disintegrants; Suspending Agentss. Product Keywords: Excipients for Liquid Dosage Form; Suspending Agents; PE-0643; Sodium Starch Glycolate; Disintegrants; Suspending Agentss; ; 9063-38-1. UNII: N/A. Chemical Name: Sodium carboxymethyl starch. Grade: Pharmceutical Excipients. Administration route: Oral. Dosage Form: Oral capsules and tablets. Stability and Storage Conditions: Tablets prepared with sodium starch glycolate have good storage properties. Sodium starch glycolate is stable although very hygroscopic, and should be stored in a well-closed container in order to protect it from wide variations of humidity and temperature, which may cause caking. The physical properties of sodium starch glycolate remain unchanged for up to 5 years if it is stored at moderate temperatures and humidity. Source and Preparation: Sodium starch glycolate is a substituted derivative of potato starch. Typically, commercial products are also crosslinked using either sodium trimetaphosphate (Types A and B) or dehydration (Type C). Starch is carboxymethylated by reacting it with sodium chloroa
Sodium Starch Glycolate Type A
Sodium starch glycolate is a white or almost white free-flowing very hygroscopic powder. Synonyms: Carboxymethyl starch, sodium salt Type A. CAS No. 9063-38-1. Product ID: PE-0641. Mole weight: 5×10^5~1×10^6. Category: Disintegrants; Suspending Agentss. Product Keywords: Excipients for Liquid Dosage Form; Suspending Agents; PE-0641; Sodium Starch Glycolate Type A; Disintegrants; Suspending Agentss; ; 9063-38-1. UNII: N/A. Chemical Name: Sodium carboxymethyl starch. Grade: Pharmceutical Excipients. Administration route: Oral. Dosage Form: Oral capsules and tablets. Stability and Storage Conditions: Tablets prepared with sodium starch glycolate have good storage properties. Sodium starch glycolate is stable although very hygroscopic, and should be stored in a well-closed container in order to protect it from wide variations of humidity and temperature, which may cause caking. The physical properties of sodium starch glycolate remain unchanged for up to 3 years if it is stored at moderate temperatures and humidity. Source and Preparation: Sodium starch glycolate is a substituted derivative of potato starch. Typically, commercial products are also crosslinked using either sodium trimetaphosphate (Types A and B) or dehydration (Type C). Starch is carboxymethylated by reacting it with sodium chloroacetate in an alkaline, nonaqueous medium, typically denatured ethanol or methanol, followed by neutralization
Sodium Starch Glycolate(Type B)
Sodium starch glycolate is a white or almost white free-flowing very hygroscopic powder. Synonyms: Carboxymethyl starch, sodium salt. CAS No. 9063-38-1. Product ID: PE-0642. Mole weight: 5×10^5~1×10^6. Category: Disintegrants; Suspending Agentss. Product Keywords: Excipients for Liquid Dosage Form; Suspending Agents; PE-0642; Sodium Starch Glycolate(Type B); Disintegrants; Suspending Agentss; ; 9063-38-1. UNII: N/A. Chemical Name: Sodium carboxymethyl starch. Grade: Pharmceutical Excipients. Administration route: Oral. Dosage Form: Oral capsules and tablets. Stability and Storage Conditions: Tablets prepared with sodium starch glycolate have good storage properties. Sodium starch glycolate is stable although very hygroscopic, and should be stored in a well-closed container in order to protect it from wide variations of humidity and temperature, which may cause caking. The physical properties of sodium starch glycolate remain unchanged for up to 4 years if it is stored at moderate temperatures and humidity. Source and Preparation: Sodium starch glycolate is a substituted derivative of potato starch. Typically, commercial products are also crosslinked using either sodium trimetaphosphate (Types A and B) or dehydration (Type C).
