Excipient (pharmacologically inactive substance)
What is it?
Colophony comes from the sap of coniferous trees such as pines, junipers, firs, and cedars. It is semi-transparent and varies in color from light brown, to yellow to black. Colophony (also known as rosin, gum rosin or rosin gum) is found in personal care and beauty products, topical medications, surface coatings, lubricants, adhesives and sealants, as well as the rosin for string instruments and dancers’ shoes. Some people have a contact allergy to colophony. Typical symptoms of a colophony contact dermatitis may include redness, swelling, itching, and fluid-filled blisters.
