# Sorbitol vs Glycerin as Humectants: Cost and Performance

Sorbitol and glycerin are both humectants, but they are not interchangeable. Each brings different moisture behaviour, sweetness and cost, and the right choice depends on the application.

Moisture behaviour
------------------

Both hold water, but they release it at different rates and have different effects on texture and stickiness. In some systems glycerin is more effective; in others sorbitol gives a cleaner result.

Sweetness and taste
-------------------

- Sorbitol is mildly sweet; glycerin is sweet but can taste warming.
- Glycerin can affect flavour release at higher levels.
- Sorbitol is more neutral in many food systems.

**Buyer tip:** compare on a cost-per-unit-of-humectancy basis, not cost per kilogram, and test in the real formulation.

Application fit
---------------

Pharma and oral care often favour sorbitol for its purity grades and neutral profile; certain foods and cosmetics favour glycerin. Match the humectant to the product, the label and the cost target.
