Hi everyone,

Is there a noticeable difference in humectancy between 1.5% of propanediol and 1.5% glycerin in a basic o/w emulsion? Does anyone have any preferences?

    You probably would not notice any difference in an emulsion.  Where the difference would be notable would be in a water-based serum where the propanediol would not have the sticky sensorial that you would get with glycerin.
