  • Help with formulating solid serum bar

    Posted by Rockstargirl on August 22, 2020 at 11:39 pm

    Here is the start of my formula: 

    Propylene Glycol 45%
    Distilled Water 15%
    Glycerin 
    Liquid allantoin (aqua/allantoin)10%
    Licorice Extract 8%
    Sodium Stearate 8%
    Room for some more liquid actives 

    it’s not hard enough. I’m looking for a smooth glide in a solid bar. 

    Any advice?

    Have you tried adding more sodium stearate? Perhaps with a little silicone?
