I've looked everywhere for information on the occlusive ratings for waxes and can't seem to find any information.
Do thickeners, such as glyceryl stearate SE, beeswax, cera bellina, etc. still allow penetration of goodies such as vitamin e, panthenol, and vitamins? Obviously, the percentage of wax would be a factor, but are some less occlusive than others? You'd think there would be some sort or rating guide out there somewhere.
Or is cetyl alcohol an option? I'm asking htis in regard to facial and lip serums.
