Antiseptic wipes

Abstract

A personal skin cleansing wipe comprising a flexible substantially dry matrix formed from synthetic, woven, non-woven or knitted fibers impregnated with a substantially anhydrous antimicrobial, antiseptic, antifungal solution in an amount wherein the matrix retains its substantially dry characteristics and the treatment solution includes an amount of PVP-iodine as active in solution in glycol and or glycerin. The treatment solution, in addition to an effective amount of PVP-iodine as active, contains surfactants, preferably Tego® Betaine CK D, and optionally a compatible fragrance and / or moisturizer. The wipe is activated with water just prior to use.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a continuation-in-part of application Ser. No. 12 / 589,820 filed Oct. 30, 2009, which in turn is a continuation-in-part of application Ser. No. 11 / 118,197 filed May 2, 2005.FIELD OF INVENTION[0002]The present invention relates to a personal skin-cleansing wipe incorporating a non-aqueous solvent, a surfactant, and an antimicrobial / antifungal / antiseptic component. The wipe contains PVP-iodine as active component which is incorporated in substantially anhydrous form. The wipe is activated by the addition of water before use and residual debris, including PVP-iodine remaining on the skin following use is removed by rinsing with water. The structure of the wipe should preferably comprise synthetic fibers. The wipe can be used as an antiseptic hand washcloth, an antifungal body or skin wipe or for first aid or wound cleaning, among other applications.BACKGROUND OF THE INVENTION[0003]It is well known that topical skin surfaces...

AI Technical Summary

Benefits of technology

"The present invention is about a special skin-cleaning wipe that can kill harmful bacteria and fungi. The wipe is made by soaking a dry cloth in a solution containing PVP-iodine and a surfactant. The cloth can be made from synthetic, woven, non-woven, or knitted fibers. When the wet cloth is rubbed on skin, it creates a foam that cleans the skin without leaving any stains or discoloration."

Problems solved by technology

Currently, there are only two over-the-counter antimicrobial active ingredients enjoying unqualified approval by the U.S. Food and Drug Administration for use in antiseptic skin cleansing, for first aid and wound cleansing, and in antifungal cleansing wipes.

However, there is a long list of negative attributes associated with the use of the ethyl alcohol.

It dries and irritates healthy skin and stings injured or abraded skin.

Moreover, as ethyl alcohol is highly volatile, it dissipates rapidly if not packaged in a proper barrier container.

Other disadvantages of ethyl alcohol include its stringent regulation by governmental agencies, its ability to erode some metals, its tendency to remove paint and varnish and to delaminate some plastics.

While elemental iodine has been used in antiseptic applications (U.S. Pat. No. 4,045,364), elemental iodine is known to possess a number of undesirable properties.

Free elemental iodine is highly toxic, irritative, sensitizing, odorous and it also causes stains and readily vaporizes due to sublimation.

But such wet wipes are expensive because they require barrier packaging to prevent evaporation or “dryout”.

Also contributing to the expense of such wipes is the need for special binder-free substrates for hydro-alcoholic formulations and starch-free substrates for aqueous iodophor formulations.

Thus, the use of these ingredients has been limited and reserved for higher risk healthcare and medical environments where other considerations justify the higher costs.
