White Jelly-Like Particles in Serum

Asked by: nonae.maple On: July 22, 2016 Product Type: Cosmetics

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?

Answer

Based on the information provided, the white jelly-like particles in your serum are likely undissolved thickeners or gel makers.

  • What is it? It is the thickening agent or gel-forming ingredient that has not fully dissolved.
  • What causes it? This occurs due to insufficient mixing during the formulation process. The ingredients were added but not blended long or vigorously enough to ensure complete dissolution and dispersion.
  • Which substances cause it? Common culprits are thickeners or gel makers such as:
    • Gel Makers (e.g., Pro Polymer Acrylate Crosspolymer)
    • Thickeners (e.g., Xanthan Gum)

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.
