Shea butter is a common skin-care product. I use the "raw" stuff with no additives. Hyaluronic acid is a high-end skin-care product that’s supposed to prevent wrinkles; it is sometimes injected into lips or the penis to plump them up, and sometimes into knee joints as a lubricant.
I used to mix various other things into them when I was working on the scars; now that those are gone, I just use the acid and butter. They’re both supposed to make the skin soft and stretchy. I credit it with being able to make significant gains without developing stretch marks.
On a scale of 1 to 5, it’s about a 4 as a lubricant. It doesn’t stain underwear or bedding, is absorbed by the skin in a few hours, doesn’t dry out in long pumping sessions, and any excess left over after PE work wipes off with a paper towel.
I have not been happy with any of the water-based lubricants, and note that most "silicone" lubes are water-based now. Real silicone lubes cost a *lot* more, and some of them aren’t friendly to sheets or underwear.
Plain old mineral oil will work reasonably well as a pumping lube. It’s cheap, odorless, non-staining, and you can wipe most, but not all of it from your skin. I don’t care for the slightly slimy feel if I don’t wash afterward, but it might not bother you. If you decide to try mineral oil, look in the "laxative" aisle; that’s the plain stuff without additives. In my area, all the mineral oil in the "baby care" and "skin care" sections is contaminated with "fragrance"; some kind of chemical that smells like a goat’s asshole.
