Liquid Soap Formulation: Thickener Alternatives, pH Adjustment, and Foam
คำถาม
I have a liquid soap formula using Pro Polymer. I have a few questions regarding formulation adjustments:
- Can I substitute Pro Polymer with other thickeners like Xanthan Gum (clear gel type) or Sugarthick? What are the considerations for using these alternatives?
- Can I mix ingredients 1-4 (Lauryl Glucoside, Coco-Wash, emulPearl, Glycerin) and 7 (BroadPreserve or Phenoxyethanol) and adjust the pH using Citric Acid before adding the thickener?
- Are there any suggestions for improving foam in the formula?

Formulation Questions from Topic 1288
Based on the discussion in topic 1288:
Substituting Pro Polymer
Yes, you can use Xanthan Gum (clear gel type) or Sugarthick as alternatives to Pro Polymer in your liquid soap formula.
- Using Xanthan Gum will result in a different texture compared to Pro Polymer, potentially being more sticky and having air bubbles, as noted in the thread. To mix Xanthan Gum, it's recommended to disperse it in water first to form a gel before adding other surfactants to avoid excessive foaming.
- Sugarthick was suggested as a potentially cheaper and easier-to-mix liquid option that also works as a thickener for detergent-based formulas and can help reduce irritation from harsh surfactants.
While Organic Natural Thickener (ECOCERT) was mentioned, the discussion focused more on Xanthan Gum and Sugarthick as direct alternatives for cost-saving.
Adjusting pH
Yes, you can mix ingredients 1-4 (Lauryl Glucoside, Coco-Wash, emulPearl, Glycerin) and 7 (BroadPreserve or Phenoxyethanol) and adjust the pH using Citric Acid before adding the thickener (like Xanthan Gum or Sugarthick). Adjusting the pH while the mixture is less viscous is generally easier.
Additional Suggestion
The discussion also suggested adding a foam booster like Creamy Foamer or BabyFoam to get more abundant and softer foam, potentially reducing the amount of Lauryl Glucoside or Coco-Wash slightly.
