“1,4-Dioxane is primarily used in solvent applications for the manufacturing sector; however, it is also found in fumigants and automotive coolant. Additionally, the chemical is also used as a foaming agent and appears as an accidental byproduct of the ethoxylation[1] (1,4-Dioxane - Wikipedia) process in cosmetics manufacturing. It may contaminate cosmetics and personal care products such as deodorants, shampoos, toothpastes and mouthwashes.[2] (1,4-Dioxane - Wikipedia)”

MHarris seems obsessed with product quality (read some of his old posts) and is likely in a better position than any of us to worry about trace contamination…
I know.. it’s good to know about these things though I think.
