Oil is coagulating?

So I am now trying a new oil to use while pulling, Sunflower Oil (cold-pressed) from Trader Joe's, and it coagulates into blobs in my mouth during the pull. When I'm finished (20 min)swishing and then spit, the oil appears to have become thick white blobs.

My previous oil, which was unrefined organic sesame oil, did not do this. The oil was watery and white in color upon completion.

Is there something wrong with this new sunflower oil? Should I go back to using the sesame oil?

PS: I've only been oil pulling for about 2 months for 20min every day and have not experienced any positive results or negative side effects. It seems like it's not doing anything at all.
