Water-Soluble Modified Starch Powder is a pharmaceutical-grade compound developed from corn-based raw materials. It is formulated through a specialized process involving modified starch, inorganic salts, cyclodextrins, and auxiliary ingredients, yielding a highly stable and functionally versatile excipient. This powder exhibits excellent water solubility, high dispersibility, neutral pH, and strong flow characteristics, making it ideal for use as a carrier in water-soluble formulations such as powders, granules, or oral sachets.
Designed specifically for pharmaceutical and veterinary industries, this product solves common problems such as clumping, moisture absorption, and instability in conventional excipients like anhydrous glucose or oral glucose. It can significantly enhance drug stability, improve appearance, reduce production losses, and increase efficiency across various manufacturing environments.
Its microgranular structure offers large surface area and high adsorption capacity, ensuring uniform mixing with active pharmaceutical ingredients (APIs) without affecting their stability or assay results. The product is chemically inert and free from crystallized water or reactive ions, resulting in prolonged shelf life (up to five years in original packaging). It dissolves rapidly in both hot and cold water, forming a transparent, non-stratifying solution.
This innovative starch-based material can replace traditional carriers and reduce dependency on expensive excipients, offering both cost efficiency and improved product performance. It is particularly effective in formulations that demand excellent solubility, moisture resistance, and bioavailability enhancement.
