No misconception. You're right. It is an emollient and is conditioning for any skin type when used as a butter or in a lotion. Babassu's fatty acid profile is very similar to coconut so it has about the same benefits when used in a body product and soap. In soap, it reacts the same way to lye as coconut - cleansing, hardness, creates bubbly lather. It's a great substitute for CO in facial soaps, IMO. It's gently cleansing at 20%-25% and unclogs my pores. Unfortunately, it's a bit more expensive and may not have as long as a shelf life as CO.
However, I think it's worth it since I don't use a large percentage in facial soaps.
eta: I'm using the last bar from a batch I made about 18 months ago. (I know it sounds odd but I don't go through facial soap like I do with bars for the shower.) Anyway, there isn't any DOS so you don't think you'd have to be concerned about rancidity once babassu is saponified.
I've tried it as a whipped butter but it stiffened up more than shea so it didn't maintain the whipped texture. I thought if I had added a liquid oil it probably would have stayed whipped. Later I found a recipe for
Whipped Babassu on swiftcraftymonkey and she used a liquid oil so her's stayed whipped. However, it was still lovely on my skin - spread easily because it melted very quickly, didn't take long to absorb and didn't leave me feeling greasy.

I'm sorry. I didn't mean to hijack your thread.
