Gum rosin, a marvel of natural resin, is meticulously extracted from the sap of majestic pine trees. Revered for its eco-conscious, non-toxic, and biodegradable attributes, this exquisite light yellow to transparent solid captivates with a gentle pine fragrance. It showcases a density of 1.07-1.09 g/cm³ and boasts a versatile softening point between 70-85ºC. The resin's acid value, ranging from 150-180 mg KOH/g, highlights its exceptional solubility in organic solvents like ethanol and acetone, while remaining impressively water-insoluble.
