I found it quite interesting that of all the products in the line that I regularly use, you managed to pick out those products which I do not use. Interesting, huh?
As for Rudolph Steiner, I certainly wouldn't assume anything that he might be doing regarding the changes in the Dr. Hauschka line. And that's me.
And regarding Titanium Dioxide:
Another word for it is Titania. Titania is the largest moon of Uranus.
There are far more to material substances than just the chemistry and physical composition of them. After viewing a shot of Titania, I'm not so sure that Rudolph Steiner would be as displeased as you profess.
And still, I won't be eating the products with titanium dioxide, given that I already don't use them.
