Sulfodene May Not Be Safe
from Tiamae

Backstory:
      Sulfodene (for dogs) Worked for Her
      Sulfodene — The Dog Shampoo that Helps P

Hello: I was browsing the internet and came upon the following pages (listed below) from your site that recount the experience of a woman who tried Sulfodene for her scalp and had great success.  I noted your caution in promoting it before you had all the facts including dangers and cautions from the manufacturer located on the Material Safety Data Sheet (MSDS).  I want to thank you for your caution and I appreciate your desire to ensure products are safe before you promote them on your site.  However, I feel there is some room for confusion, and I believe you only have half of the facts.  You see, the woman states that she wasn't able to successfully treat her scalp with scalp oils and shampoos, so she finally tried Sulfodene.  Because she states she had no luck with shampoos, I suspect she is not using the Sulfodene dog shampoo, but rather the Sulfodene skin medication for dogs.  Each product has different active ingredients.  The dog shampoo seems less threatening with sulfur, coal tar and triclosan as ingredients, though I am not completely convinced of the 100% safety of triclosan, and from what I understand its safety is still under the investigation by the FDA.  However, the active ingredient for the Sulfodene skin medication, which I believe is the product to which the woman was referring, is 2-mercaptobenzothiazole, also known as MBT, which is indeed considered hazardous and listed as such on the product's MSDS.

You see, I first came into contact with the Sulfodene skin medication when my dog had a terrible condition on her chin.  She had marble-like swellings that were red, inflamed and irritated.  There was no hair left around the swellings and the irritation was so great she was constantly scraping her chin on the ground.  Also, upon squeezing them, I found they were filled with puss.  I had very little money at the time, so I thought I'd try an OTC treatment before taking her to the vet.  At the local Walmart I found a bottle of Sulfodene medicated liquid, the same liquid to which I believe your reader was referring.  The bottle said it would help heal skin irritations that were red, inflamed, losing hair and complicated by secondary infection.  I figured it would be a perfect match since it was also very affordable (one bottle was only three dollars).  However, I always like to know the details of chemicals to which I am exposing my household, so I looked at the ingredients listed on the back.  2-mercaptobenzothiazole was listed as the active ingredient and the only other ingredient listed was 2% alcohol.  I looked up the active ingredient and found enough concerning information that I decided not to use it on my dog after all.  I found a pollution score card for the active ingredient, 2-mercaptobenzothiazole, also known as MBT, and the results were very concerning.  Though on the Sulfodene skin medication MSDS it states that there is no known (or, in other words, proven) carcinogenic effects of the Sulfodene medicated product, the active ingredient MBT is indeed a SUSPECTED carcinogen, as well as a suspected cardiovascular/blood toxicant, gastrointestinal/liver toxicant, immunotoxicant, neurotoxicant, and skin/sense organ toxicant.  MBT also ranks more hazardous than most chemicals in 2 out of 7 ranking systems.  Though enough studies have not yet been performed to determine the exact toxicity of MBT on all systems of the body, the fact that it is suspected to be toxic to so many vital human systems helped me to decide not to use the product.  I didn't want to risk being part of the evidence that could prove all the suspicions to be true.  Many products in the past have been shown to be extremely effective, and only later were they discovered to also be very toxic or even deadly.  Just because they get the job done doesn't mean they don't harbor other harmful side effects.  I believe that today is no different, and we still must exercise caution with products that are suspected hazards, even if they haven't yet been proven to be harmful.  Thus, I feel it is important for everyone to know all about the various suspected dangers, so they can make a well-educated decision for themselves that best fits their needs, desires and lifestyles.

Below, I have included a number of sites for your convenience, including the two pages on your site to which I am referring, the environmental score card for MBT, and a new link to the MSDS for Sulfodene medicated dog shampoo (the old link listed on one of your pages wouldn't work for me when I clicked on it, so I looked up another one), as well as the MSDS for the Sulfodene skin medication which I believe your reader was using.  Thank you kindly for your time and attention.  I hope this information helps shine some more light on the matter!

Sincerely, -Tiamae
