Does anyone add Titanium dioxide directly to lye water?

I have used Zinc Oxide instead of TD a lot. But I have learned it yellows quite a bit faster so I would recommend it only if you are going to be selling them fairly soon so they don't yellow on your customers. It works at close to the same ratio and imo is close, but not quite as white. I used it a good bit when making soaps like pumpkin spice that have an orangey/yellow tint anyway so it works.

Yep, I wasn't as happy with the zinc oxide either. Going to stick with the TD.

I am just noticing and reading this thread and now I'm second guessing my decision to order TD from Nurture instead of mica (I've never used either one before).
Question: I keep reading that some of you pre-dissolve your TD in water and store it in a squeeze bottle. Wouldn't this need a preservative since it's water based?
