Facial Mask Tube Swelling and Bursting Issue

Question

I have a facial mask formulation packaged in a plastic tube. After just one day, the tube swells and bursts. The pH of the formulation is 6.00, and I used Phenonip P4 1% + Mild Preserved Eco 2% as preservatives. What could be causing this issue? Please provide your full formula and manufacturing process details to help diagnose the problem.

Hello,

Thank you for providing the details about your mask formulation, including the pH (6.00) and the preservatives you added (Phenonip P4 1% + Mild Preserved Eco 2%).

The issue of the plastic tube swelling and bursting after only one day is a significant problem. This typically indicates either:

Microbial growth: Microorganisms can produce gas as a byproduct of their metabolism, especially in formulations containing natural ingredients. Even if you believe your process is clean, natural materials can carry a high microbial load.
Chemical reaction: Some ingredients might react with each other or the packaging material, producing gas.

As the staff mentioned, to accurately diagnose the cause and recommend a solution, it is essential to know the complete list of ingredients in your mask formulation and the detailed steps of your mixing process. This information will help determine if there are potential incompatibilities, sources of contamination, or issues with the formulation stability.

Please provide the full formula and process details so that the staff can assist you further in troubleshooting this issue.
