Buyers sourcing sorbitol usually face one decision before anything else: liquid or powder. Both are the same polyol, CAS 50-70-4, INS 420, HS code 38246000, and both are covered by BP, USP, EP and FCC standards. What changes is how you handle them.
What the two forms actually are
Sorbitol Solution is a water-based syrup, commonly supplied at 70% solids. Sorbitol Powder is a crystalline solid, typically above 99% solids. The difference sounds small but it drives packing, freight and process design.
When the solution wins
- Your formulation is already liquid and you do not want a dissolving step. Toothpaste, mouthwash, liquid sweetener blends and syrup bases all fall here.
- You want dust-free handling. A drum pumps straight into the process; powder needs dust control and weighing.
- You need the non-crystalline behaviour. A 70% solution stays in solution and does not grain out the way crystalline powder can in a high-solids system.
When the powder wins
- Dry blends, tableting, chewing gum base and bakery premixes. Adding water is a disadvantage in these processes.
- Freight economy on solids. A 70% solution carries roughly 30% water, and you pay freight on that water. Per tonne of actual sorbitol solids, powder is the lighter shipment.
- Long storage without crystallisation risk. Powder keeps well in a sealed bag; solution must not be allowed to freeze.
Packing and storage
Solution is supplied in drums, with 275kg the standard drum size for bulk shipment. Powder is supplied in 25kg kraft bags with a PE inner liner. Solution should be stored above freezing and mixed before use if it has been cold; powder should be kept dry and sealed to avoid caking.
What to ask your supplier
- Which grade: food, cosmetic or pharma excipient
- For powder, the mesh range, because fine and granular powder behave differently in dry blending
- A batch COA with the parameters you actually test
- Certification status: ISO 9001, ISO 22000, Halal and Kosher where your market requires it
The short version: if your line is wet, buy the solution; if your line is dry, buy the powder. If you are not sure, tell the supplier your process and let them recommend the form, not the other way round.
