Liquid Glucose 80% BP
Liquid Glucose 80% BP is a purified, concentrated aqueous solution of glucose (dextrose), typically containing 80% w/w of glucose and other related saccharides. It is a clear, colorless to pale yellow, viscous liquid with a sweet taste. Derived primarily from starch hydrolysis (usually corn or rice), it is widely used in pharmaceutical formulations as a sweetener, humectant, and stabilizing agent. Liquid glucose enhances the viscosity and mouthfeel of syrups, acts as a base for tonics and elixirs, and provides a source of energy in nutritional supplements. The British Pharmacopoeia (BP) standards ensure its purity and safety for pharmaceutical and food use.

British Pharmacopoeia (BP) Specification for Liquid Glucose 80%

• Description: Clear, viscous, colorless or slightly yellow liquid; sweet in taste.
• Glucose Content: Not less than 80% w/w (expressed as D-glucose equivalent).
• pH: Between 4.0 and 6.5.
• Clarity and Color of Solution: Should remain clear and colorless.
• Sulphated Ash: Not more than 0.1%.
• Heavy Metals: Not more than 10 ppm.
• Dextrin (qualitative test): Passes test (confirms presence and type of polysaccharides).
• Microbial Contamination: Should comply with BP microbial limits for oral preparations.
• Reducing Sugars (as Dextrose): Should comply with the stated range (usually 30%–45% depending on the grade).

Foreign Sugars (e.g., fructose or maltose): Within acceptable BP limits.
