Sorbitol Solution 70% BP
Sorbitol Solution 70% BP is a clear, colorless to slightly yellowish, viscous aqueous solution containing 70% w/w of D-sorbitol, a sugar alcohol derived from glucose. It is widely used in pharmaceutical formulations as a sweetener, humectant, and stabilizer. In oral liquids, it serves as a non-cariogenic sweetening agent and improves the palatability of syrups and suspensions. Additionally, sorbitol acts as a laxative at higher concentrations due to its osmotic properties. The British Pharmacopoeia (BP) standard ensures that the solution is safe, consistent in quality, and suitable for pharmaceutical use.
