It’s a common misconception that if a product has the same name as something that is in an industrial product that it is the same in both application. There are several different grades of ingredients – industrial, cosmetic, food grade, pharma grade. Industrial is the lowest grade and has the lowest purity and that is what is used in cleaners. Pharma grade is the highest purity and reserved for pharmaceutical use. All of our products are food grade. Hope that helps.

Relax. Methocel is Dupont’s brand of methyl cellulose. It is derived from cotton fibers or at least that was the raw material when I visited the plant years ago while working on a graduate degree in Chem. Engineering.
It is a common thickening agent for any number of products from cleaners to food and beverages.
I vividly remember walking through a unit where a pipe had burst and long tendrils of a very viscous fluid that could best be compared to snot in appearance was hanging from the burst pipe all the way to the floor, twenty feet below.
Guys in Tyvek suits and rubber boots were busy shoveling the methyl cellulose from the floor into wheelbarrows so the plumbers could get in with their ladders and man lifts to fix the pipe.
