Question

I have a serum formulation that contains white jelly-like particles. What are these particles, what causes them, and are they beneficial or problematic?

  • Which substances cause it? Common culprits are thickeners or gel makers such as:

This indicates that the ingredients are not fully compatible or properly dispersed in the formula. It generally does not provide any additional benefit to the product's performance.
