Potato starch is a fine, white powder derived from potatoes. It has a high water absorption capacity and good swelling properties, making it effective as a tablet disintegrant.
Chemical Name and CAS Registry Number: Solanum tuberosum starch [9005-25-8]
Functional Category: Disintegrant; binder; diluent
Commonly used as a disintegrant (3-10%), binder, and filler in solid dosage forms. It provides rapid tablet disintegration and improved powder flow properties.
Potato starch exhibits higher swelling and disintegration efficiency compared to other starches. It is particularly useful in formulations requiring rapid disintegration in aqueous media.
