  • accelerators
  • activators
  • antidegradants (antioxidants, antiozonants)
  • vulcanizing agents
  • retarders
  • reinforcing agents
  • fillers
  • pigments
  • processing help
  • blowing agents

Allergy can probably occur to any of these chemicals, although rubber accelerators seem to cause the biggest problems.

What are rubber accelerators?

Rubber accelerators are chemicals used to speed up the rubber manufacturing process (vulcanization). This process makes untreated natural rubber latex suitable for use in the manufacture of many rubber products. There are many types of rubber accelerators in use, but the ones listed below cause the most cases of rubber contact. dermatitis:

How did I get allergic to rubber accelerators?

In these cases, the rubber allergy can come as a consequence of trying to protect your hands from others. Allergens.

Am I allergic to rubber accelerators?

The allergy to rubber accelerators is diagnosed by medical history and by special allergy tests, patch tests These tests can identify which specific rubber accelerators you are allergic to.

The thiuram mixture tests four thiuram chemicals with one test. One of these four will cause about 9 out of 10 cases of allergy to thiuram mixture. Similarly, the mercapto mixture tests for 3 chemicals in one test.

You can do a self allergy test on a rubber product, but this should only be done after talking to your dermatologist. Do this only with items designed to stay on the skin, such as underwear or shoes. Initially, allow the item to be in contact with the skin of your forearm for a short period of time, say 1 hour. For the next 4 days, look for any reaction. If no reaction occurs, slowly extend the period of contact with your skin to a maximum of 48 hours.

Do not test insecticides or other chemicals in this way.

What should I do to avoid a rubber accelerator allergy?

The best way to avoid a rubber accelerator allergy is to learn about products that contain rubber accelerators. However, it is generally difficult to determine which products contain rubber accelerators and which do not.

Minimize your exposure to all rubber products. Use alternative products made from vinyl, plastic, wood, leather, or fabric. Although some rubber gloves are labeled 'hypoallergenic', it is wise to contact the manufacturer to determine if they contain any of the rubber accelerators to which you are allergic. Vinyl gloves may be a suitable alternative, although some people are allergic to rubber and vinyl. Tactylon® gloves are a good alternative for most people. Be aware that some rubber gloves provide less protection against viruses and certain chemicals than rubber gloves. Discuss your glove requirements with your supplier / manufacturer.

If you are sensitive to rubber accelerators and are undergoing dental work or surgery, you should inform your dentist or doctor so that they can use alternative gloves that do not have rubber accelerators or perform a patch test in advance with the gloves that plan to use.

Avoid shoes made with rubber accelerators. Try on the shoes by wearing them for a few days and watch for a skin rash (shoe dermatitis) or do a patch test on the shoes. Any socks or socks that have been worn with shoes that cause allergies can become contaminated with rubber. They should not be reused, as even washing may not remove the contaminant.

Rubber-free condoms (for example, Durex Avanti) and plastic diaphragms may be suitable contraceptive alternatives. Cover the padded arms of upholstered furniture with a towel and avoid walking barefoot on rubber-coated rugs.

Acute dermatitis can be treated with wet bandages of Burrow's solution or dilute vinegar. Short courses of systemic Corticosteroids can speed healing. Chronic shoe dermatitis may need to be treated with long-term treatment of current corticosteroids and / or coal tar and emollients. It is essential that you wear shoes that are free from the causative allergens.
