Contact dermatitis is a skin condition that develops from repeated exposure to certain chemicals. In dental, this exposure is commonly found from remnants of chemical accelerators used in the manufacture of gloves.

D Chemical accelerators are used in glove manufacturing to stabilize synthetic rubber molecules into strong and durable gloves. These accelerators are the major cause of Allergic Contact Dermatitis reactions.

Accelerator-Free gloves are manufactured without the use of accelerator chemicals such as Mercaptobenzothiazole (MBTs), thiazoles, thiurams and dithiocarbamates to help protect glove users from a nonallergic reaction to any of the numerous irritants from both glove and non-glove associated sources.

For nitrile glove users, the possibility of glove allergy should be considered in all case of hand dermatitis. the usual culprits are additive chemicals called accelerators. because of their effects on the chemical reactions that change liquid rubber formulations into tough rubber films. Accelerator-free nitrile gloves are strongly recommended for people who are sensitive to these additives.

It varies, depends on the skin conditions (personal experience). The effectiveness can lead from 1 week to several months.
