Added titanium dioxide to a batch but below is what it looked like when I shaved top of bar. The titanium dioxide I use is oil solueable so I add it to my warm oils prior to adding lye. Any ideas as to what happened and how I can eliminate this.

Was it just not well-mixed before the lye was added? I'd actually have pulled some oil out into a separate cup, used my frother to mix it all in nice and even, and then poured that oil-TD mixture back into the batch and mix that all together before adding lye.

My TD says oil soluble but it dissolves better in water.
Use oil or water (water or oil from the recipe) and dissolve the TD in it making a thick smooth paste before adding it to the oils.

I use water soluble as I had issues with oil soluble leaving spots too. Not quite that many but more times than not. Try adding it to water as PJ states, it may disperse better.
I use oil soluble but I pre-mix several ounces using a frother to mix it, if I decide I want to fuss with it. The longer it sits the better it mixes, I am talking days to weeks not just when I want to use it. The oil soluble TD can be mixed in either oil or glycerin. There is a TD available that can be mixed in either or as Shunt mentioned there is water soluble TD. I still find water TD is better premixed so any undissolved particles fall to the bottom. Soapsupplies.net sells a premixed TD which is easy. I actually do not use much TD anymore just work with the discoloring fo's by separating off the batter and not adding fragrance to the entire batch and using a recipe with light color oils. It is so much easier than dealing with TD. Here is the link for the pre-mixed td, just scroll past the micas http://www.soapsupplies.net/colorant.html My daughter always pre-mixed hers in a pint mason jar using the balloon beater in her hand mixer.

And here is a video on how pre-mixing TD.
She mentions buying stainless steel ball bearings, but I couldn't find any, so I bought SS sinkers in the fishing section of WalMart. Works great for shaking up pre-mixed colors in bottles.

I have tried the ball bearings and my daughters method works much better for me
When I first make my pre-mix colors, I use a mixer (I use a Badger). But I prefer to store it in a squirt bottle with mixing balls, because all it takes is few vigorous shakes to ensure the color is still well mixed. I should have mentioned that in my post above, but we were about to leave to do some shopping and I cut my post short.
