Definition of the wetting angle of apricot GUM (Gummi Armeniaceae)water solutions, collected from the different regions of Armenia

Abstract

Apricot gums 5-15% water solutions having the contact angles in the range 0°<θ<45° are impermissible to be used as stabilizers in drug technology. Meanwhile, apricot gum 20% water solution from Vayots Dzor, having wetting contact angles in the range 45°<θ<90°, is characterized as a limited hydrophobic solution with typical diphilic molecules, which may convert the hydrophobic molecules into the hydrophilic, and vice versa, hydrophilic molecules in the hydrophobic, regulating the wettability in different technological processes.
