What about castor oil? A popular BPCR lube here is 50/50 beewax and castor oil.
I did a quick search and literally stumbled upon this. It kinda sounds like it is exactly what you are looking for. Used in cosmetics.
PEG-40 Hydrogenated Castor Oil
Okay
Used for conditioning, thickener, and to keep product from separating into oil and water components. This is made from Castor oil that's been thickened by hydrogenation, then processed with polyethylene glycol.
This is an off-white solid that's water soluble in warm water, considered to be safe and mild in cosmetics. The main difference between PEG-40 Hydrogenated Castor Oil and PEG-40 Castor Oil is that the Hydrogenated Castor Oil is more solid at room temperature, and it has less of a "Castor" scent. [Hunting (Conditioning) pg 318].

I've seen that too, it's in my "little black book" of lube ingredients. Thanks for the mental jog.
