The tint process for ChloraPrep Scrub Teal™ and Hi-Lite Orange™ tints is a patented technology that adds color to the solution as it enters the sponge pad. When applied to the skin, each tint allows for easy visualization of the prepped area. Unlike iodine-based preps, which are brown, Scrub Teal and Hi-Lite Orange tints are easy to see when applied to a variety of skin tones.
The dyes in Scrub Teal and Hi-Lite Orange tints are Food, Drug and Cosmetic (FD&C) Green #3 and Yellow #6 dyes, and have been "generally recognized as safe" (GRAS) by the Food and Drug Administration (FDA). For an ingredient to be listed as GRAS, extensive safety testing is conducted, reviewed and accepted. FD&C Green #3 is a common colorant used in many applications throughout the healthcare field (e.g., eye angiography and screening for ocular dryness, routine lab testing, dye injections, histological/cytological stains for cancer screening of tissues). FD&C Green #3 and Yellow #6 were found to be stable when combined with the 2% chlorhexidine gluconate/70% isopropyl alcohol ChloraPrep formulation, which offers proven, stable and uncompromised chlorhexidine-based solutions.
