Glycerin on top of cream surface as extra layer of protection
Would it be a good idea or a bad idea to put a little layer of glycerin on the surface of a cream AFTER it’s cooled to room temp. (as in, the next day after making it)?
I figure the glycerin will give an extra layer of protection to the cream against bacteria & fungi AND from drying on the surface.Of course I have preservative in the cream, and there are lids on the jars, I’m just figuring the glycerin would be an extra little ‘layer of protection’. I would pour off the glycerin before using the cream because personally, I do not like the stickiness of glycerin and have switched to sodium lactate at 2% for its humectification (new word) properties.Thanks for any comments. -

Don’t do it.

What is the down-side to putting a little glycerin on top of cream? I’m ignorant here…

If the product is made and packaged properly there is no need.
It would look amateurish - it would appear as if the product were separating. -
I only want the glycerin on there till the cream’s going to be used, then I’ll pour it off before using it. I certainly see your point that if the glycerin was just sitting on the surface, it would appear like something’s gone awry.

If it’s just for your own use, try it and see - but it might destabilize your emulsion if it’s o/w.
Commercially, I would strongly recomend against it.
