How bad is Glyceryl Stearate for Foam?
I have been experimenting with Glyceryl Stearate in Syndet/Combo Bars.
0.5% undeniably changes the cohesion of my mix quite successfully. My bar also contains 5% Sodium Stearate.
How much of a negative impact on foaming would Glyceryl Stearate create? Am I going down a bad path ?
Polawax NF gave excellent results but I am trying to avoid the PEGs and Polysorbates on the label.

Have you tried cetearyl alcohol? They all reduce foaming the question is how much. I think the best idea would be to experiment with fatty acids and fatty alcohols that you don’t mind to have on the label and see which is the best. I use GMS in surfactant product I make and it does reduce foaming but still acceptable for me.

Well, I am looking for an emulsifier I can use. I have tried
Lanette N (90% cetearyl alcohol, 10% Sodium Cetearyl Sulfate) - Not a good skin feel/ glide and requires a high percentage.
Polawax NF - excellent.
Candellila Wax - Not an emulsifier but tried and it had the opposite effect, less cohesion and plasticity.
The syndet in question contains high levels of Fatty Acids and Fatty Alcohols (25% not including emulsifier) with no issues with foaming.
I also have on hand Euperlan 3000 by BASF - Glycol Distearate, Laureth-4, CAPB.
