Problems solved by technology

Unfortunately, these desired characteristics of elastomeric gloves create a harsh environment for the wearer's skin.
For example, perspiration is a common problem for glove wearers, and the resulting moist environment may lead to various skin problems, including, for example, growth of fungi and yeast, as well as bacterial and viral infections of the skin.
This constant cleaning is harsh on the skin, causing excessive skin dryness that may exacerbate other skin problems.
However, while powders may still be acceptable in certain applications, they are typically undesired in surgical or cleanroom-type environments.

example

[0044] The ability to form an elastomeric glove in accordance with the present invention was demonstrated. Initially, a pre-heated, glove-shaped former was dipped into a coagulant solution that contained calcium nitrate, calcium carbonate, a surfactant, and water. The coated former was then dipped into a dip tank containing compounded, pre-vulcanized natural rubber latex. After dipping, the former was removed from the natural rubber latex dip tank and leached with water. Thereafter, the latex-coated former was cured in an oven at a temperature of 115° C. for about 20 minutes. The glove was manually removed from the former by turning the glove inside out as it was stripped from its corresponding former. After being removed from the former, the glove was also rinsed in deionized water. The thickness of the resulting glove was 0.24 millimeters. After the drying process, the glove was turned inside out and placed into a chlorinator. Chlorine gas mixed with a water stream was injected in...

Abstract

An elastomeric glove that contains a hydrogel coating is provided. The present inventors have discovered that the hydrogel coating is capable of improving donning (damp and / or dry) and also imparting certain other benefits to a wearer of the glove. Specifically, the hydrogel coating includes an active agent that is retained within a crosslinked hydrogel network. When the hydrogel coating is exposed to an aqueous environment, it swells, allowing the active agent to diffuse through pores and contact the skin of a wearer.

Description

BACKGROUND OF THE INVENTION [0001] Elastomeric gloves are formed to fit tightly against a user's hand and provide good gripping and tactile characteristics during use. In addition, elastomeric gloves are normally liquid-impermeable to provide a barrier between the wearer and the environment in which the gloves are used. Unfortunately, these desired characteristics of elastomeric gloves create a harsh environment for the wearer's skin. For example, perspiration is a common problem for glove wearers, and the resulting moist environment may lead to various skin problems, including, for example, growth of fungi and yeast, as well as bacterial and viral infections of the skin. In addition, those who utilize elastomeric gloves in the medical field frequently clean their hands with soap or sanitary alcohol formulations. This constant cleaning is harsh on the skin, causing excessive skin dryness that may exacerbate other skin problems. [0002] In the past, the wearer-contacting surface of el...
