Zinc PCA causing thinning in gel-cream formula: How to fix?

Based on the staff's reply, the issue with your formula not thickening is likely due to Zinc PCA (ID: 252). Zinc PCA is an electrolyte that can interfere with the thickening agent, Satin Cream Maker (ID: 247).

Regarding your questions:

1. Why is the formula not thickening? As the staff explained, Zinc PCA (ID: 252) is an electrolyte that causes the formula to thin, preventing proper thickening with Satin Cream Maker (ID: 247).
2. Will adding Pro Polymer (ID: 234) at 1% help? Yes, the staff suggests using an electrolyte-tolerant gel maker like Pro Polymer (ID: 234) at 1% can help thicken the formula even with Zinc PCA (ID: 252).
3. Will adding Pro Polymer (ID: 234) cause stickiness? Pro Polymer (ID: 234) is known for creating a non-sticky gel texture.

To achieve your desired fast-absorbing, non-sticky gel-cream texture suitable for acne-prone skin, the staff recommends:

• Removing Zinc PCA (ID: 252), OR
• Keeping Zinc PCA (ID: 252) but adding it last and increasing Satin Cream Maker (ID: 247) to 2-3%, OR
• Using an electrolyte-tolerant gel maker like Pro Polymer (ID: 234) at 1% or Xanthan Gum (ID: 216) at 1%. Adding Pro Polymer (ID: 234) at 1% is a good approach.
