Abstract

Antimicrobial protection may be provided to protective gloves by mixing an antimicrobial agent in a glove material plastisol so that the antimicrobial agent migrates to the exposed surfaces of the gloves when the agent on the glove surface has been depleted. Antimicrobial gloves suitable for use in the food industry may be manufactured using a cold dip process with a plastisol that includes the following weight percentages of (a) a polymer resin, such as polyvinyl chloride (PVC), polypropylene polyethylene (PE), or polyurethane, 43 to 53%, (b) a plasticizer, such as DINP, 43 to 53%, (c) a stabilizer, such as CaZn, 2.7 to 4.7%, and (d) triclosan (2,4,4'"'"'-trichloro-2'"'"'-hydroxydiphenyl ether), 0.3 to 1.0%.

Claims

1. An antimicrobial protective glove having an antimicrobial agent homogeneously distributed in a material from which the glove is formed, and in which the agent migrates to the exposed surface of the glove to restore the antimicrobial effect when the agent at the exposed surface has been removed, the glove material comprising by weight percent:

polyvinyl chloride, 48%;

a plasticizer, 48%;

a stabilizer, 3.7%; and

triclosan, 0.3%,

wherein said triclosan internal to the glove material will migrate to the surface of the glove when said triclosan at the surface of the glove is removed.

2. The glove of claim 1 wherein said plasticizer is DINP.

3. The glove of claim 1 wherein said stabilizer is CaZn.

4. The glove of claim 1 wherein said glove is seamless.

5. An antimicrobial protective glove having an antimicrobial agent homogeneously distributed in a material from which the glove is formed, and in which the agent migrates to the exposed surface of the glove to restore the antimicrobial effect when the agent at the exposed surface has been removed, the glove material comprising by weight percent:

polyvinyl chloride, 43 to 53%;

DINP plasticizer, 43 to 53%;

CaZn stabilizer, 2.7 to 4.7%; and

triclosan, 0.3 to 1.0%,

wherein said triclosan internal to the glove material will migrate to the surface of the glove when said triclosan at the surface of the glove is removed.

6. The glove of claim 5 wherein the weight percentages are:

said polyvinyl chloride, 48%;

said DINP plasticizer, 48%;

said CaZn stabilizer, 3.7%; and

said triclosan, 0.3%.

7. The glove of claim 6 wherein said glove is seamless.
