FAQs

What are the primary formulation applications of Watercress Leaf?
Most buyers use it in detox-category liquid formulations and greens beverage bases. As with any new water-soluble extract, pilot-test in your specific base before committing to a full production run.

Which carrier should I choose — water, propylene glycol or glycerin?
Water alone suits most aqueous formulations. Propylene glycol improves cold-stability and solvency in preserved systems; glycerin gives a milder, skin-friendlier carrier for leave-on formulations. PG and glycerin variants are offered at 500 g and 1 Kg, with PG also available at 5 Kg.
