VWR Soluble Starch (from potato) is a technical-grade polysaccharide with the empirical formula (C₆H₁₀O₅)n, used in titrimetric analysis, adhesive formulations, and various industrial and educational settings. Supplied as a white powder, it dissolves in hot water to form a colloidal solution and is best known for its use as a visual indicator in iodometric titrations, where it forms a deep blue complex with iodine.
This technical-grade starch is suitable for non-critical applications that do not require food or pharmaceutical-grade material.
