Body Wash Separation, but everything is water soluble?
I’m having some issues with a body wash formulation. In the lab, we had no stability issues and everything remained completely uniform. After our production run, we’re seeing a clear layer forming on top of the formula, and the bottom layer is cloudy. What can be causing this, and how can I fix it?
Formula:
Water - q.s.
Glycerin - 5%
Xanthan Gum - 0.5%
Euxyl K 712 - 1.5%
Tetrasodium Glutamate Diacetate - 0.2%
Surfactant Blend (40% Active: C14-16 Olefin Sulfonate, Cocamidopropyl Hydroxysultaine, Cocamide MIPA) - 28%
Decyl Glucoside - 4%
Sodium Chloride - 0.3%
Citric Acid - q.s. pH to 4.5 -

Through what period does this develop?

Was your xanthan gum properly hydrated in the manufactured batch?

Have you tried a solubalizer?

I’ve seen so many times separation issues of surfactant based formulas that have glucosides and gums. I’d replace Xanthan gum. If you have nothing to suspend, then rely on the power of mixing anionic-amphoteric-salt. You could alternatively add a fatty amide (like Cocamide DEA or similar).
