Gum rosin, a divine gift from nature, is meticulously extracted from the sap of pine trees, celebrated for its eco-conscious, non-toxic, and biodegradable allure. This exquisite substance, ranging from a delicate light yellow to an enchanting transparent solid, whispers the faint, invigorating aroma of pine. Its robust density lies between 1.07-1.09g/cm³, while its versatile softening point spans gracefully from 70-85ºC. With an impressive acid value of approximately 150-180mg KOH/g, it boasts remarkable solubility in organic solvents like ethanol and acetone, yet remains proudly insoluble in water.
