Product Overview & Quality

Product Name: Starch soluble
Brand: Kemaus (Product Code: KA-526-2)
Grade: Analytical Reagent (AR Grade). Premium product manufactured under strict Kemaus laboratory standards. The raw starch structure has been chemically modified to achieve ready solubility in hot water, delivering an exceptionally clear indicator solution free from raw starchy residues. It features minimal residue on ignition and ultra-low trace contamination to ensure high-contrast color shifts.
Physical Properties: Odorless, fine white powder.
Solubility: Soluble in hot water (forming a clear to slightly opalescent solution); insoluble in cold water and alcohol.
Key Use: Heavily utilized as a primary chemical indicator in iodine-based redox titrations (including iodometric and iodimetric assays). Starch binds with free iodine to produce an intense, deep-blue complex that sharply transitions to colorless at the exact titration endpoint. Also applied in microbiology laboratories for formulating specific culture media to execute starch hydrolysis tests, and used in biochemistry to evaluate amylase enzymatic profiles.

Safety & Hazards

Classification: Not classified as a hazardous substance according to GHS regulations. It features an excellent safety profile with zero toxic skin reactions.
Health Risks: Direct eye contact with large amounts of dust may cause minor, temporary mechanical irritation or short-term redness. Inhalation of fine dust may trigger minor coughing or sneezing.
First Aid Measures: Flush eyes immediately with plenty of flowing water. Seek medical advice if irritation develops or persists.

Handling & Storage

Storage: Hygroscopic material and biodegradable. Subject to moisture absorption and microbial contamination if left unprotected. Must be stored in the original, tightly sealed Kemaus container in a cool, strictly dry, and well-ventilated space at stable room temperature (below 30 degrees Celsius).
Precautions: Wear standard personal protective equipment (PPE), including laboratory gloves, safety glasses, and a particulate dust mask. Ensure the container is capped tightly immediately after each use to protect the absolute dryness and analytical performance of the indicator.
