❓ Frequently Asked Questions

❓ Why is my gel not thickening?

Carbomer needs to be neutralized to work. Add a base (TEA/NaOH) dropwise while mixing until pH reaches 6-7.

❓ Is Carbomer natural?

No, it's synthetic. For natural gelling, use Xanthan Gum or Guar Gum.

❓ How much Carbomer do I need?

Typically 0.2-0.5% for gels, 0.1-0.3% for lotions. Very economical due to low usage rate.
