The problem with those recipes is two-fold. One they are not CP and are doing a rebatch. The lotions are pre-mades. There is nothing wrong with that if that is the direction you want to go but if you want to do CP you are going to need to come up with your own recipe. The other problem is that they are calling for MSM which is not the same as sulfar. MSM is used for pain and I think that would be awesome in a lotion/cream. Not sure of the benefits of it in soap though.
Sulfar soaps are made for acne and you should be making a recipe that is extremely conditioning with little or no coconut or palm kernel oils. Palm oil, tallow or lard would be great in this. I would recommend a 10% addition of the sulfar to get the best results.
I think I'm gong to have to make some MSM lotion because my mum has a lot of pain (she was in a pain clinic for a while) and see if this will help.
