Abstract

A method of manufacturing nitrile rubber latex medical examination gloves during which (a) the glove formers are dipped into a coagulant solution containing divalent calcium cations and calcium nitrate particles, to which has been added a composition comprising Alcohol ethoxylate, Amine oxide, Ethylenediaminetetracetic acid, Glutaraldehyde, Chlorhexidine di-gluconate, Chlorhexidine di-hydrochloride, Salisept, Titanium Dioxide, nano particle silver; and during which (b) the coated glove formers are then dipped into a nitrile rubber latex dispersion to which has been added a composition comprising Alcohol ethoxylate, Amine oxide, Lactic acid, Ethylenediaminetetracetic acid, Glutaraldehyde, Salisept; and during which (c) the nitrile rubber latex gloves are finally placed in to packaging utilizing a clear coat varnish that it is impregnated with a phenolic chlorine compound, micronized nanosilver colloid, and a quaternary compound.

Claims (8)

1. A method of manufacturing medical examination gloves comprising:

(a) contacting glove formers with a coagulant solution, to which has been added a composition comprising: 1% to 3% alcohol ethoxylate, 0.1% to 0.5% amine oxide, 0.1% to 0.5% ethylenediaminetetraacetic acid, 0.1% to 0.5% glutaraldehyde, 0.5% to 1% chlorhexidine di-gluconate, 0.5% to 1% chlorhexidine di-hydrochloride, 0.1% to 0.25% 4-isothiazolin-3-one-5-chloro-2-methyl-; 3(2H)-isothiazolone, less than 0.2% titanium dioxide, less than 0.2% nanoparticle silver to form coated glove formers;

(b) contacting the coated glove formers with a nitrile rubber latex dispersion to which has been added a composition comprising: 1% to 3% alcohol ethoxylate, 0.1% to 0.5% amine oxide, 0.1% to 0.3% lactic acid, 0.1% to 0.5% ethylenediaminetetraacetic acid, 0.1% to 0.5% glutaraldehyde, 0.1% to 0.25% 4-isothiazolin-3-one-5-chloro-2-methyl-; 3(2H)-isothiazolone to form nitrile rubber latex gloves.

2. The method according to claim 1 , wherein the coagulant solution in (a) further contains divalent calcium ions and calcium nitrate particles.

3. The method according to claim 1 , wherein the gloves are placed in antimicrobial packaging.

4. The method according to claim 3 , wherein the antimicrobial packaging contains a solution containing a phenolic chlorine compound, micronized nanosilver colloid, and a quaternary compound.

5. The method according to claim 1 , wherein the medical examination gloves are selected from the group consisting of sterile and non-sterile gloves.

6. A medical examination glove, manufactured according to the method recited in claim 1 .
