Shower Gel Too Thick: How to Reduce Viscosity?

Your shower gel became too thick after adding Sugar Thick (PEG-120 Methyl Glucose Dioleate), making it difficult to pump.

Regarding your question about using Propylene Glycol: While adding a high amount of Propylene Glycol might help reduce the viscosity, it would also dilute the other ingredients in your formula.

The recommended solution is to dilute the entire mixture by adding more of the other components in your formula (Sulfate Free Shampoo base, distilled water, Creamy Foamer, and fragrance) while keeping the amount of Sugar Thick you have already added constant. This is a better approach as it helps reduce the viscosity while maintaining the concentration of the other ingredients.
