GONIOCHROMIC INDICATOR FOR SKIN SEALANT

摘要

A skin sealant composition having a film former like cyanoacrylate and a goniochromic dye or pigment is provided. The addition of mica/metal oxide powders to the sealant formulation makes it possible to see where it has been applied, due to the mica/metal oxide's goniochromic (e.g. irhdescent or pearlescent) appearance, and it is also still possible to view the underlying skin, especially from an angle at which the color is less apparent. Thus, mica/titanium dioxide or other goniochromic or light interfering particles may be used as an additive to allow for determination of complete coverage, while not significantly obscuring the incision site.
