Abstract:
A bone cement has a liquid acrylic monomer component, a powdered acrylic polymer component and yellowish beta-carotene (Pro-vitamin A) mixed into one of the liquid or powdered component and FDC blue No. 2 Lake powder mixed into the powdered component. The beta-carotene and FDC blue adds a greenish (yellow plus blue) color to the combined liquid and powdered component. The yellowish color disappears on setting of the bone cement leaving the cement blue.
