System for providing a method for applying a skin sealant having a phase change visual indicating component

摘要

A system for providing a method of sealing skin with a film forming polymer is provided. The system includes providing an at least two part applicator containing a sealant composition in one or more frangible containers, providing instructions for using the applicator associated therewith, where the method including moving at least one of said applicator parts from a first position to a second position and applying said sealant to skin. The composition has film former, a plasticizer and 3000 to 10000 ppm of a dye that changes color when is undergoes a phase change. The color change is visible to a human eye under normal light conditions. changing dyes may be used to indicate that the composition has dried. The dyes change color in response to the phase change, i.e., drying of the film former. The dye may be added either directly to the composition, incorporated into a sponge on an applicator through which the composition is dispensed and applied, applied separately or applied simultaneously from a separate reservoir. The amount of dye in the composition can be adjusted to provide a visual cue to the user of the application area and the extent of cure though should generally be in the range of 3000 to 10000 ppm.
