Abstract

A presaturated wipe product having a dilute glutaraldehyde saturated pad secured to a layer of packaging material is provided. The saturated pad is sealed in the packaging and the entire package is subjected to γ-irradiation in order to maintain the disinfectant activity of the pad over an extended period of time.

Claims

1. A presaturated wipe product for applying an active disinfectant solution to a work surface comprising:

a first layer of packaging material;

a second layer of packaging material;

a pad secured to said second layer;

a dilute glutaraldehyde solution impregnated in the pad for providing disinfecting activity to the pad;

wherein the first layer and the second layer are heat sealed to each other so as to form a sealed envelope for maintaining the presaturated pad therein; and

further wherein the presaturated pad has been γ

-irradiated after the first and second layers are heat sealed so that said envelope maintains disinfecting activity for the glutaraldehyde over an extended period of time.

2. The presaturated wipe product of claim 1, wherein at least one of the layers of packaging material comprises a layer of foil and a layer of polyethylene.

3. The presaturated wipe product of claim 2, wherein the at least one layer comprising a layer of foil and a layer of polyethylene further comprises a layer of paper.

4. The presaturated wipe product of claim 1, wherein the pad is secured to the second layer using a bonding adhesive.

5. The presaturated wipe product of claim 1, wherein the pad is a nonwoven material.

6. The presaturated wipe product of claim 5, wherein the nonwoven material is rayon.

7. The presaturated wipe product of claim 1, wherein the dilute glutaraldehyde solution comprises less than about 2% glutaraldehyde.

8. The presaturated wipe product of claim 7, wherein the dilute glutaraldehyde solution comprises about 0.25% glutaraldehyde, about 1.5% triethylene glycol, about 0.75% inert ingredients and about 97.5% water.

9. The presaturated wipe product of claim 8, wherein the water used to prepare the dilute glutaraldehyde solution is distilled water.

10. The presaturated wipe product of claim 1, wherein the presaturated wipe product is effective on a surface having a surface area up to 40 times greater than the area of the presaturated pad.

11. The presaturated wipe product of claim 1, wherein the product is effective against gram negative bacteria, gram positive bacteria and viral agents.

12. A presaturated wipe for applying an active disinfectant solution to a work surface prepared by the process comprising:

securing a pad to a first layer of packaging material;

impregnating said pad with a dilute glutaraldehyde solution for providing disinfecting activity to the pad;

heat sealing the first layer to a second layer of packaging material to form a sealed envelope for maintaining the presaturated pad therein; and

subjecting the sealed enveloped to γ

-irradiation in order to prevent microbial growth inside the envelope and to maintain the effectiveness of the dilute glutaraldehyde solution over an extended period of time.

13. The product prepared by the process of claim 12, wherein the γ

-irradiation is used at an intensity of less than about 1.0 mR.
