Overheard someone at the grocery store this morning say, "I only buy chemical-free products—much safer." The cashier nodded enthusiastically. I almost said something, then remembered nobody likes a lecture while buying soap. But it got me thinking about how deeply this misconception runs.
Here's the thing: there's no such thing as a chemical-free product. A chemical is simply matter with a defined composition. Water is a chemical (H₂O). Salt is a chemical (NaCl). The air you're breathing right now? A mixture of chemicals, mostly nitrogen and oxygen. Everything you can touch, taste, or smell is made of chemicals. The term "chemical-free" is scientifically meaningless—it's marketing, not chemistry.
Think of it this way: saying "chemical-free" is like advertising "matter-free" shampoo. What would that even be? A bottle of nothing? The soap itself is chemicals. The fragrance, the preservatives, the water—all chemicals, whether they're synthesized in a lab or extracted from plants.
