This patient information on
Mercaptobenzothiazole is provided by John L. Meisenheimer, M.D. a board certified Dermatologist
and skin care specialist based in Orlando, Florida. This information is
not intended as a substitute for the medical advice or treatment of a dermatologist or other
physician.
The results from your patch testing showed a positive reaction (contact allergy)
to Mercaptobenzothiazole. Your immune system reacts with its defense
mechanisms with each exposure of Mercaptobenzothiazole to your skin. It is
unknown why certain individuals develop allergic sensitivities. In some it
may take repeat exposures over long periods of time before an allergy develops.
Once you have become sensitized (allergic) your immune system always "remembers"
and you will continue to be Mercaptobenzothiazole sensitive. If you
currently have eczema this chemical may be the cause but other factors may play
a role as well. This information below will help you avoid this allergen.
This agent is commonly used in the production of rubber products. It is
the most common cause of shoe contact dermatitis and rubber contact dermatitis.

Hints on avoiding chemical:
►Try to minimize your exposure to all rubber
products. It may be difficult to determine which rubber products contain
MBT. You may substitute products made of vinyl, plastic, leather, wood and
fabric.
►Be suspicious of any product containing
rubber that seems to cause a rash where it touches your body.
►Choose products listed only on your
personalized Contact Allergen Database, which has been provided to you.
Products listed on your contact allergen resource database will be free of
Mercaptobenzothiazole and safe to use.
►It may take 2 to 3 weeks of avoiding
exposure before improvement of your eruption begins.

Possible Occupational Exposures*

Machine operators
*Other occupational exposures to mercaptobenzothiazole can occur.
If you have a shoe contact dermatitis:
Wear solid leather shoes like moccasins or wood clogs (no inner or outer rubber
soles). Try insoles free of MBT to see if this makes dress shoes wearable
for you.
Socks and stockings worn with shoes containing MBT can be contaminated and may
not wash out easily and should be discarded.
Leather shoes can have mercaptobenzothiazole in soles, lining and adhesives.
Ask your shoe store for rubber free shoes.
