Syrup vs. Suspension: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on December 24, 2023
Syrup is a thick, sweet liquid, while a suspension is a mixture where solid particles are dispersed in a liquid but do not dissolve.

Key Differences

Syrup is typically a concentrated solution of sugar in water, often flavored or medicated. A suspension, however, is a heterogeneous mixture where solid particles are suspended in a liquid without dissolving.
Syrups are characterized by their viscosity and sweetness, often used as flavor enhancers or in medicines. Suspensions appear cloudy or murky due to the undissolved particles and require shaking before use to redistribute the particles.
In pharmaceuticals, syrup is used as a vehicle for delivering medications in a palatable form, especially for children. Suspension in medication allows insoluble drugs to be administered orally in a liquid form.
Syrups are generally stable and do not require special handling. Suspensions can settle over time, requiring agitation to ensure uniform distribution of the solid particles before use.
In culinary uses, syrup refers to a sweet, thick liquid used in food and drinks. In pharmaceuticals, suspension provides a means to deliver insoluble medicinal compounds in a liquid form.
