Chlorination is used for several reasons: Chlorination is a manufacturing step used to decrease the sticky or tacky feel of gloves. By reducing surface drag and creating a slippery surface, the need for powder is eliminated. Chlorination helps break down natural rubber latex proteins on or near the glove surface. Subsequent removal through multiple wash …

Chlorination reduces tackiness by oxidation and additional cross-linking of unbound or partially bound molecules on the glove surface. It involves multiple steps, each of which must be constantly monitored and carefully controlled. Under-chlorinated gloves are tacky and difficult to don; over-chlorinated gloves rapidly degrade becoming brittle and darkly coloured.

Poor chlorination practices can result in gloves that are weak, tear easily, have pinholes, are discoloured and can become brittle or gummy. Therefore, it is essential that all steps in the chlorination process be carefully regulated. Improper storage conditions can shorten the shelf life of chlorinated and non-chlorinated gloves.

Chlorination can potentially affect the shelf life of gloves. Poorly chlorinated gloves rapidly degrade. Discoloration, cracking, tearing and enhanced heat and light sensitivity may occur, thereby shortening the shelf life and reducing barrier effectiveness. Storage conditions including, but not limited to, temperature, humidity, sunlight and/or fluorescent light exposure may affect chlorinated gloves.
