Update!

I just wanted to let everyone know that I did make my own laundry detergent. It does work. I ended up using Ivory Soap bar. I couldn't find the laundry soap bar. The first load I washed didn't come out too clean. So, I decided with my next load to use a full cup of detergent. Yup, it works great now! I'm going to keep on making my own detergent! Completely satisfied!
