I have a body wash formula (and dish soap, for what it's worth) that did not meet my viscosity expectations so I added some xanthan gum to the formulas as a quick fix in order to get to the desired viscosities.
Both formulas are now constantly getting clogged at the tip of the dispenser pump, from what I can only assume is the xanthan gum drying out and forming the stringy "snot" that I've only now heard about.
Does everyone agree that the xanthan gum is actually the culprit, or could it be a different ingredient? I've heard that non-ionics can get 'sticky' sometimes - has anyone had issues with alkyl polyglucosides forming this crust when exposed to air?
I still have plenty of bulk product yet to be bottled, so I'm wondering if there is anything I can add to the batch that is already produced in order to eliminate the residue from forming once it's in the bottle?
General ingredients for each formula:
Body wash - pH 5.5
Sulfonate/Sultaine (was hoping this would provide appropriate viscosity)
Dish Soap - pH 7.5
