Question

I am making a formula using Pro Polymer, Mahad extract, and `Eye Preserved™ (Polyaminopropyl Biguanide)`. Why does the mixture turn into a rubbery lump?

Answer

Based on the staff's response, the issue you encountered with your formula turning into a rubbery lump when combining Pro Polymer and Mahad extract is due to an incompatibility with the preservative Eye Preserved™ (Polyaminopropyl Biguanide).

  • The staff confirmed that Eye Preserved™ (Polyaminopropyl Biguanide) is incompatible with gel bases, causing the mixture to coagulate.
  • The company has temporarily stopped selling this preservative because of this issue and is currently sourcing a replacement that is compatible with general gel formulations.
  • The company has offered compensation for the damaged ingredients.
