Abstract
Embodiments of a skin dye protectant formulation comprise at least about 30% by weight of a film forming composition, at least about 40% by weight of a solvent, water, at least 0.1% by weight of a dye, and at least about 1% to about 5% of antioxidants, wherein the formulation is operable to substantially maintain the color of the dye when the skin dye protectant formulation is subjected to gamma sterilization.
