    It depends on your comparison. If you compare it to other paste / waxy type lipids, it should not be “a good occlusive”, more so when compared to petrolatum.

    Good stuff…but makes things shiny…as it is just lip gloss. :) 

    But I use it…at low rates…then mattify the heck out of it.

    It is, chemically speaking, related to the waxy component in petrolatum ;) . Mix with a liquid hydrocarbon such as isoeicosane and you have fake vaseline, possibly from renewable feedstock.
