The problem with chemicals is knowing the way they are added, exact quantities and when in the process. I have spent a lot of money over the years developing chemicals and paying to have someone trying to reverse engineer some of them. It is very difficult with most of them. e.g. if you try making mayonnaise and you add all the correct ingredients, but don’t add them in the correct order and at the correct speed then it simply curdles. This is what happens with chemicals only it is a lot more complicated than Mayonnaise. I say leave well alone, leave chemicals to the experts, pay the money if they work for you.
