Many products I find around the house (shampoo, toothpaste, food, etc.) have their ingredients listed on the packaging, and they all seem to have incredibly long lists.
How does a simple product like toothpaste, found in every house, have *so many* ingredients, and yet still cost only a few £? If you removed just one, surely it would be basically the exact same thing? Do they all get added in the factory, and how did anyone figure out how much of each is needed and why?
Sorry for the list of questions, I just have so many! Thanks 🙂
