No it isn't made from petroleum... I mean it can be just because chemistry is amazing, but in industry they use another process. It could be made alongside any plant oil or tallow processing.
The problem is that it is such a simple, and small, molecule that it could be doing a whole lot of things and is extremely hard to track. That makes it suspicious to me, but that is all I got. It is generally categorized as harmless, but to me that just means there are no obvious short term effects. Long term effects are hard to discern.
I couldn't find reference to the ingredients that Tom's used as chemically processed. Any other reference? I've been suspicious of them also... as the most popular brand that makes fluoride free, they may be substituting something just as bad and not listing it or something.
I'll give you my take because it is slightly different. Your head generates oils, let's call them natural oils. When you wash hair first the "soap" takes effect which removed the smells, but also all of the oils. Then the other ingredients take effect. For nearly all cheap soaps these are silicone based things like dimethicone. Silicone based oils do make hair dry and lifeless longterm, at least from what I can tell.
The oils have a function, so if you are removing them, you probably should be replenishing them, with something that can serve a similar enough purpose. Unlikely to find a shampoo that can do both the soaping and the replenishing together.. they are literally contradictory effects.
So what you are left with is the realization that you shouldn't expect shampoo to replenish your hair, and have to think about what would do that properly.
If the shampoo is doing that wrong, then you are just left with soap, and a question as to the point of shampoo.
The word processed is overused and doesn't specifically make something bad. You can argue that mixing your ingredients is processing them.
That being said I love your recipe.
I'm only calling out that we should have some understanding of what about the processing makes it bad. Like lots of heat treating/solvent extracting processes are bad. Lots of stabilizers are bad.
Looking through this thread to compare what other people like/hate, this recipe has the best ingredients. There is some concern about long term baking soda (abrasive) use depending on how often you brush, but that is relatively small. Make me some toothpaste! :-D
It should be fine. Your body generates peroxidases quite rapidly.
As to whether you need it, that isn't as clear. If you think it gives you a refreshing feeling then it is ok. I would strongly suggest oil pulling as an alternative since it helps clearing lymph and that is more important for fresh breath.
Some toothpastes have flavor crystals, some have other additives. I imagine they add xylitol or other sugar alcohol in crystal form to get a minty cool feeling when you brush. We'd have to know which toothpaste you mean to be sure.
Thank you! If it wasn't for posts like this I would feel crazy sometimes. This is what I was calling out with u/rooftoptendie, and I am somehow accused of personal attacks. His comments need a lot of support for the level of confidence provided.
This thread is literally called "Red pill me on toothpaste," and you advocate mostly the same advice I would expect to hear from the dentist. If you don't see a disconnect there then there is not much I can do to help you.
Is thinking that I'm downvoting you across the board a cope of your own? As if only I would disagree?
Sodium salts dissolve readily in water. The presence of sodium does not have any substantial effect on the characteristics of dissolved fluoride. I'm pointing out the complete lack of knowledge of chemistry, or attention put into these posts.
This doesn't mean much if the shots are given same day as delivery, as is often the case. It confounds the cause so you can't be sure.
