    Can anyone advise on how propylene glycol affects a formula, I have been using 9% in my pomade which goes too thin and goey when broken down in the hands, would a different humectant work better?

    “Oil and wax phase is 42% with required HLB calculated at 11.
    I am using ceteareth 25 at 4.5% and peg 7 glycerol cocoate at 9.5% in the complete formula, rest of formula is water at 15% and polymers, clays.”

    I’d be surprised if your product would be stable. PEG-7 Glyceryl Cocoate has an HLB value of 11 (source: makingcosmetics) and found and another source with an HLB value of 10.  Ceteareth 25 has an HLB value of 16.27 (source: makingcosmetics).  You are using two O?W emulsifiers, but your emulsion is W/O.  Unless you are trying a GelTrap strategy, I don’t see this formulation can be stable. 
    Another issue, 15% emulsifiers seems a lot. 

    Hi, thanks for feedback, why would my formula be water in oil emulsion, isn’t that decided by what emulsifiers I use with their relevant hlb numbers. Would it not be possible to mix 15% water as oil in water emulsion. I use water to blend polymers.
