propolis extract (30% flavonoids) on the webpage states that it is also soluble.
Propylene Glycol ,
Butylene Glycol but from trying In Bee propolis 0.1% formula
Propylene Glycol 5% not completely dissolved, would like some advice on what to do to dissolve completely. There is no sediment left. Thank you very much.
