Issue
Skin antisepsis is carried out before a surgical procedure. The use of a colored antiseptic is essential for clearly showing the disinfected area. This provides assurance that a given area has been properly disinfected. For a colored antiseptic to be effective for users, particularly surgeons, it should color the skin sufficiently, be hypoallergenic, and be presented in a stable, ready-to-use solution.
Existing solutions either provide insufficient coloration of the disinfected area, have high allergic risks, or an instable formula. This instability can materialize through inhomogeneity of the antiseptic/colorant mix, diminishing the properties of the end product and/or ease of application.
