dish washing liquid ingredients

[darkoshi]

I noticed today that Seventh Generation dish washing liquids contain benzisothiazolinone and methylisothiazolinone. Earlier this year, I had read that some people are allergic to those ingredients and can get skin rashes from them. I don't think I am sensitive to those chemicals, but I usually wear gloves while washing dishes anyway. Ecos is another brand I use, which doesn't have those ingredients.

Some Seventh Generation Products contain Methylisonthiazolinone ("MIT") and/or Benzisothiazolinone ("BIT") as preservatives to keep the product stable and free of microbial contamination over its shelf life. Although these products have been evaluated to be hypoallergenic and/or Made for Sensitive Skin, it does not mean that a product will not cause any allergic reaction or irritation in any person, and that a small percentage of individuals may have some form of allergic reaction or irritation to MIT or BIT. Always use as directed.

Deleo tested Lucy for sensitivity to around 70 different allergens and, at last, finally reached a conclusion: Lucy had a severe response to methylisothiazolinone.
At home, her parents tracked down the source of the MI — Suave Kids Body Wash, a product made by Unilever and marketed as “hypoallergenic” and “safe for kids’ delicate skin.”

“Of note, products marketed as ‘gentle,’ ‘sensitive,’ ‘organic,’ or ‘hypoallergenic’ often contained MI, thus emphasizing the importance of consumer scrutiny of product choices,” the researchers noted.

As for labels that use words like “natural” and “hypoallergenic,” Deleo says those terms mean nothing and shouldn’t guide your buying choices.

Indeed — even the federal government notes that “there are no Federal standards or definitions that govern the use of the term ‘hypoallergenic.'” The term means whatever a particular company wants it to mean… The term ‘hypoallergenic’ may have considerable market value in promoting cosmetic products to consumers on a retail basis, but dermatologists say it has very little meaning.
