Specification strategy
What buyers should specify before comparing Calendula Flower Extract.
Calendula Flower Extract grades can differ in marker profile, extract ratio, carrier system, colour, sensory profile and physical powder behaviour. These variables should be confirmed against the exact commercial specification.
For this ingredient, commercial specifications may be differentiated by flavonoids and triterpenes where specified. NutriCo does not assume every available grade uses the same target; the current specification should be used for confirmation.
