Petroleum Jelly

White Petrolatum, also known as Petroleum Jelly, often recognized under the trademarked name Vasoline, is one of the most useful skin protectants.

Vasoline has always been sold to consumers in small tubs.   This makes zero sense unless the goal is to sell as much of the stuff as possible.

With a tub, every time you use the stuff you dip your finger in the tub, pulling out a small bit for whatever purpose, you leave all sorts of germs, skin oils, and other crap (sometimes literally) on the remaining stuff.  After I've done this for awhile, I'm motivated to buy a new tub next time, wasting most of the earlier tub contents.

OR, if I use one tub of Petroleum Jelly for mechanical purposes, such as lubricating the corner of the door threshold, I'm motivated to get another tub for personal uses, because I don't want any of the crud from the doorway getting into my personal care.

It's much more reasonable to have Petroleum Jelly in tubes, allowing you to squeeze out exactly what you need and leaving the rest unadulterated.  This is the way it is sold to dermatologists and other medical doctors.

But since Vasoline was first sold to consumers in tubs, virtually everyone else who sells Petroleum Jelly in a retail store sells it in something like a Vasoline shaped tub so they'll recognize what it is.

The now disappearing Walgreens was the one retail store where you could buy Petroleum Jelly in nice blue flexible plastic tubes where you can squeeze it out like a professional.

It looks like when I need to buy more Petroleum Jelly in a tube, I'm have to get some professional variant at Amazon.  And I worry that the tubes may not be as nice as the Walgreens ones were.

100% pure Petroleum Jelly is generally far superior to all the other sorts of products which add extra ingredients, such as Aquaphor.  Now, Aquaphor IS conveniently sold in tubes.  But those extra ingredients are almost never necessary or useful but just create the conditions for the product to degrade over time.
