If asked would I rather have detergent suds that comes with the potential side effects of a cancer causing agent, I say a resounding - NO! SLS is put in most sudsing agents from Shampoos, facila cleanser, bath gels, shaving cremes and even our tooth paste where it is quickly absorbed through the mucosa. Is it any surprise so many people have cancer when it is SLS is in so many products that an accumulation could casue damage, yet no one lets the public know on their containers. Products without SLS can be bought. But even items marked as "Organic" can carry SLS. You can't get around reading labels today and checking out ingredients yourself. The FDA does not forbid their usage or make big corporations put it under a "caution" warning. WE have to protect ourselves.

I found this chemical listed in an expensive designer pet shampoo in a main pet store described as watermelon skin soothing! My dog is tiny and delicate. I dumped it and found an earthbath product instead.
