I can appreciate where you're coming from @Gaisy59
and I regret that you find our discussion of tweaks to be stressful.
But I have to say I don't see anything inappropriate about discussing adjustments to a formulation to make the product meet the needs of a wider group of people. Teresa's original recipe (babassu with clay) in this thread was a tweak of other people's ideas. The idea of using magnesium hydroxide was a "tweak" of T's recipe that was suggested by Irish Lass. The combination of babassu and mag hydroxide is thus an amalgam of tweaks.
Given how this idea came about, I don't know that anyone can draw a line in the sand and say the "original idea" for this deo is on one side of the line and all "tweaks" are on the other. I agree you can argue a 2 ingredient formulation is really simple and adding ingredients to increase the glidy-ness and melt temperature is adding complexity. But if the added complexity also adds usefulness and pleasantness to the product so it pleases a wider group of people, I see that as a positive thing.
Look at general soap making and all the crazy things people add to soap or do to soap. I think a fair bit of it is silly, but I can see people are having fun, so I generally don't say much if I think there is no harm in what they're doing. I see the discussion here in much the same vein -- people are having fun, the tweaks are hopefully helping the basic formulation work better for more people, and the results are not harmful as best we can see.
