Benefits of technology

[0007]The present invention is directed to wipes and packaging for a plurality of wipes that in combination help maintain the original constitution of a wipe lotion incorporated into a wipe. More particularly, the present invention relates to wipe lotions incorporated into a wipe substrate and to barrier packaging for a plurality of wipes. The combination of wipe lotion and barrier packaging maintain an essentially constant concentration of volatile and nonvolatile components of the wipe lotion in each wipe throughout the shelf life of the packaged wipes. The plurality of wipes can be packaged under reduced pressure, e.g., a vacuum, or at atmospheric pressure.
[0009]a) a wipe lotion containing volatile and nonvolatile ingredients and having a rheology that helps prevent settling of the wipe lotion in the barrier package and that maintains an essentially constant concentration of active agents in each wipe throughout the life of the multiwipe product, and

Problems solved by technology

This approach is unacceptable for wipes containing a drug because the drug dosage must be constant from wipe to wipe in a multiwipe package over time.
The need to provide equivalent efficacy for all wipes in a package containing more than one wipe has been difficult, and has limited the commercialization of sophisticated products in multiwipe form.

example

[0074]In order to demonstrate the present invention, sunscreen wipes were prepared and packaged in flow wrap film under vacuum to reduce the headspace in the package to essentially zero. The packages then were placed in an environmental chamber at 50° C. for 14 days to simulate a long teen storage of the wipes packages at room temperature. The packages were removed from the chamber, opened, and the wipes were weighed. This weight was compared to their initial weights. The data from this example is summarized in Table III.

[0075]The data in Table III shows that when the headspace is reduced to essentially zero, the migration of volatiles in the wipe stack also is greatly reduced. Because the elimination of headspace in flow wrap packaging is difficult to achieve in practice, an experiment was performed to determine the effect of headspace reduction on improvement in wipe stability, as measured by a reduction in volatiles migration.

[0076]In this respect, a wipe package was prepared (i....

Abstract

A multiwipe package having enhanced wipe storage stability is disclosed. The wipe package contains a stack of wipes in a barrier packaging film, wherein the headspace in the package between the stack of wipes and the packaging film is minimized.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of the filing date of U.S. provisional Patent Application No. 60 / 900,235, filed Feb. 8, 2007.FIELD OF THE INVENTION[0002]The present invention relates to wipe products having an enhanced ability to maintain efficacy throughout the shelf life / expiration dating necessary for commercial products. More particularly, the present invention relates to wipes and packaging designs that impart wipe stability in packages containing a plurality of wipes per package.BACKGROUND OF THE INVENTION[0003]The explosive growth of wipes has been well documented by multiple market research organizations and periodicals. Once a market led by the simple baby wipe, the wipe industry has blossomed into a wide variety of wet, dry, and chemically-treated dry wipe products for industrial, household, and personal care applications.[0004]As wipes are developed for sophisticated applications, care must be taken to ensure that the wipe ...
