Dextrine White / Yellow- 1 Kg Packs

Dextrine White / Yellow, commonly known as Dextrin, is a starch-derived carbohydrate material produced through the partial breakdown or thermal treatment of starch. It consists of a mixture of lower-molecular-weight carbohydrate chains containing glucose units linked primarily through glycosidic bonds. White and yellow dextrins differ in their processing characteristics and physical appearance, making the specific type relevant to laboratory selection. This material is generally supplied as a white to yellow powder and is useful in chemistry practicals, material studies, and selected research procedures involving starch-derived substances. Dextrin is also studied for its solubility, adhesive properties, and behaviour in aqueous systems. Its composition is variable, so it does not have one universal molecular weight or a single definitive molecular formula. Lab Wale offers Dextrine White / Yellow in 1 kg packs for appropriate educational, experimental, and research laboratory applications.

Key Features of Dextrin

• Starch-derived carbohydrate composition: Dextrin consists of shorter glucose-based carbohydrate chains formed through the partial breakdown or thermal treatment of starch.
• White and yellow variants: Available dextrin types differ in colour and processing characteristics, making identification of the required variant important for laboratory work.
• Variable molecular composition: Its polymeric structure means that molecular weight depends on the distribution and length of the carbohydrate chains.
• Useful aqueous behaviour: Depending on its type and preparation, dextrin can disperse or dissolve in water and is suitable for investigating the behaviour of starch-derived materials.
• Laboratory investigation potential: Its carbohydrate chemistry and binding properties support appropriate studies in polymer chemistry, material science, and educational experiments.

Laboratory Applications of Dextrin

• School and college chemistry practicals: Used in supervised demonstrations and experiments involving starch-derived carbohydrates and their physical properties.
• Carbohydrate chemistry studies: Supports investigations into starch breakdown, carbohydrate structure, and changes in material properties following starch processing.
• Solubility and dispersion experiments: Used to examine the behaviour of carbohydrate materials in water under different experimental conditions.
• Material science research: Suitable for selected studies of starch-derived binders, film-forming behaviour, and interactions between carbohydrate materials and other components.
• Adhesion and formulation investigations: Used in appropriate laboratory studies evaluating the binding properties of dextrin in paper-related materials and other technical formulations, depending on the specific grade and variant.

Frequently Asked Questions About Dextrin

What is Dextrin used for in laboratories?

Dextrin is used in carbohydrate chemistry experiments, studies of starch-derived materials, solubility investigations, and selected material science research. Its binding and dispersion properties can also be examined in technical formulation studies. The appropriate application depends on the white or yellow variant and the specifications required by the experimental method.

What is the chemical formula of Dextrin?

Dextrin is a variable-composition carbohydrate material commonly represented by the general formula (C₆H₁₀O₅)ₙ. The value of n depends on the length of the carbohydrate chains. C₆H₁₀O₅ represents the repeating anhydroglucose-unit composition rather than the complete molecular formula of every dextrin molecule.

What is the CAS number of Dextrin?

The CAS Registry Number commonly associated with dextrin is 9004-53-9. This identifier is used for the general dextrin material. Because white and yellow dextrins can differ in processing and properties, verify that the specified variant matches the requirements of the intended laboratory application.

What is the difference between White Dextrin and Yellow Dextrin?

White and yellow dextrins differ primarily in their processing history, colour, and certain functional properties. These differences can affect solubility, viscosity, and binding behaviour. The appropriate variant should be selected according to the experiment or formulation, rather than assuming that the two types are interchangeable in every procedure.

How should Dextrin be stored and handled safely?

Store dextrin in a tightly closed container in a cool, dry, well-ventilated location, protected from moisture and excessive heat. Minimise dust generation during handling, avoid unnecessary inhalation, and use appropriate eye protection and gloves. Keep the material away from incompatible substances, particularly strong oxidising agents, and follow the applicable Safety Data Sheet and laboratory waste procedures.

Storage Conditions for Dextrin

Store Dextrine White / Yellow in its original, tightly closed, compatible container in a cool, dry, well-ventilated area. Protect it from moisture, excessive heat, and physical contamination. Keep the material away from incompatible substances, particularly strong oxidising agents, and ensure that the storage area remains clean and dry. Follow the supplier’s specific storage recommendations for the selected variant.

Precautions for Handling Dextrin

Review the relevant Safety Data Sheet before use and wear suitable protective gloves, safety goggles, and laboratory clothing. Avoid generating or inhaling airborne powder, and use appropriate ventilation when handling quantities that may produce dust. Prevent contact with incompatible chemicals and clean up spills using methods that minimise dust dispersal. Dispose of residues according to institutional chemical-waste procedures and applicable local requirements.
