June Junk Claim #3 – Mrs. Meyers Clean Day Dish Soap Not So Clean As It Contains 1,4-Dioxane

June Junk Claim #3 is Mrs. Meyer’s Clean Day Liquid Dish Soap and the company’s claim that the products are “always EARTH FRIENDLY.”

Mrs. Meyer’s products are sold and marketed as “green” products. The packaging is retro inspired cute.

But, the thing is, they are not as eco-friendly as you think. For example, the Dish Soap was found to have high levels of the carcinogen 1,4-dioxane. In fact, according to testing commissioned by the Organic Consumers Association (OCA), Mrs. Meyers’ Clean Day Dish Soap had the highest levels of 1,4-dioxane in the group of products tested. The levels in the Mrs. Meyers Clean Day Liquid Dish Soap were 204 parts per million (ppm), ten times higher than any other similar product in the study.

1,4-dioxane is a by-product of the ethoxylation process. Ethoxylation is used to make certain ingredients milder and change solubility and foaming properties. It involves the addition of petroleum-derived ethylene oxide. You’ll find 1,4-dioxane in products with ethoxylated ingredients, usually identified by the “eth” – such as sodium laureth sulfate. Several “eth” ingredients are derived from natural sources – such as coconut – so you’ll find carcinogenic 1,4-dioxane in a number of products that claim to be derived from natural ingredients.

Unfortunately, the ethoxylation process results in a contaminant, 1,4-dioxane. So those allegedly naturally derived ingredients can have a carcinogence contaminant that is not identified on the ingredient label.

And Mrs. Meyer’s Liquid Dish Soap has it.

I don’t know if using the product poses a health risk. Since it is a rinse off product intended for use on dishes, I wouldn’t think that there is much dermal exposure (exposure through the skin) at all. Even if used as a hand soap I doubt there is any significant dermal exposure. And exposure from inhalation is probably minimal too.

But, the presence of carcinogenic 1,4-dixoane as a result of using petroleum derived ethylene oxide doesn’t really seem earth friendly to me.
